DevicePolicyManager

Activity action: ask the user to add a new device administrator to the system. The desired policy is the ComponentName of the policy in the EXTRA_DEVICE_ADMIN extra field. This will invoke a UI to bring the user through adding the device administrator to the system (or allowing them to reject it).

You can optionally include the EXTRA_ADD_EXPLANATION field to provide the user with additional explanation (in addition to your component's description) about what is being added.

If your administrator is already active, this will ordinarily return immediately (without user intervention). However, if your administrator has been updated and is requesting additional uses-policy flags, the user will be presented with the new list. New policies will not be available to the updated administrator until the user has accepted the new list.

Activity action: Starts the provisioning flow which sets up a managed profile.

A managed profile allows data separation for example for the usage of a device as a personal and corporate device. The user which provisioning is started from and the managed profile share a launcher.

This intent will typically be sent by a mobile device management application (mdm). Provisioning adds a managed profile and sets the mdm as the profile owner who has full control over the profile

This intent must contain the extra EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME.

When managed provisioning has completed, an intent of the type ACTION_PROFILE_PROVISIONING_COMPLETE is broadcasted to the managed profile.

If provisioning fails, the managedProfile is removed so the device returns to its previous state.

Input: Nothing.

Output: Nothing

Activity action: have the user enter a new password. This activity should be launched after using setPasswordQuality(ComponentName, int), or setPasswordMinimumLength(ComponentName, int) to have the user enter a new password that meets the current requirements. You can use isActivePasswordSufficient() to determine whether you need to have the user select a new password in order to meet the current constraints. Upon being resumed from this activity, you can check the new password characteristics to see if they are sufficient.

Activity action: begin the process of encrypting data on the device. This activity should be launched after using setStorageEncryption(ComponentName, boolean) to request encryption be activated. After resuming from this activity, use getStorageEncryption(ComponentName) to check encryption status. However, on some devices this activity may never return, as it may trigger a reboot and in some cases a complete data wipe of the device.

Result code for setStorageEncryption(ComponentName, boolean) and getStorageEncryptionStatus(): indicating that encryption is not currently active, but is currently being activated. This is only reported by devices that support encryption of data and only when the storage is currently undergoing a process of becoming encrypted. A device that must reboot and/or wipe data to become encrypted will never return this value.

Result code for setStorageEncryption(ComponentName, boolean) and getStorageEncryptionStatus(): indicating that encryption is active.

Result code for setStorageEncryption(ComponentName, boolean) and getStorageEncryptionStatus(): indicating that encryption is supported, but is not currently active.

Result code for setStorageEncryption(ComponentName, boolean) and getStorageEncryptionStatus(): indicating that encryption is not supported.

An optional CharSequence providing additional explanation for why the admin is being added.

The ComponentName of the administrator component.

A Parcelable extra of type PersistableBundle that allows a mobile device management application that starts managed profile provisioning to pass data to itself on the managed profile when provisioning completes. The mobile device management application sends this extra in an intent with the action ACTION_PROVISION_MANAGED_PROFILE and receives it in onProfileProvisioningComplete(Context, Intent) via an intent with the action ACTION_PROFILE_PROVISIONING_COMPLETE. The bundle is not changed during the managed profile provisioning.

A String extra holding the SHA-1 checksum of the file at download location specified in EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_DOWNLOAD_LOCATION. If this doesn't match the file at the download location an error will be shown to the user and the user will be asked to factory reset the device.

This extra is part of the EXTRA_PROVISIONING_ADMIN_EXTRAS_BUNDLE.

If the ACTION_PROVISION_MANAGED_PROFILE intent that starts managed provisioning contains this extra, it is forwarded in the ACTION_PROFILE_PROVISIONING_COMPLETE intent to the mobile device management application that was set as the profile owner during provisioning. It is usually used to avoid that the user has to enter their email address twice.

A String extra holding the Locale that the device will be set to. Format: xx_yy, where xx is the language code, and yy the country code.

Use in an NFC record with MIME_TYPE_PROVISIONING_NFC that starts device owner provisioning via an NFC bump.

This MIME type is used for starting the Device Owner provisioning.

During device owner provisioning a device admin app is set as the owner of the device. A device owner has full control over the device. The device owner can not be modified by the user and the only way of resetting the device is if the device owner app calls a factory reset.

A typical use case would be a device that is owned by a company, but used by either an employee or client.

The NFC message should be send to an unprovisioned device.

The NFC record must contain a serialized Properties object which contains the following properties:

• EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME
• EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_DOWNLOAD_LOCATION
• EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_DOWNLOAD_COOKIE_HEADER, optional
• EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_CHECKSUM
• EXTRA_PROVISIONING_LOCAL_TIME (convert to String), optional
• EXTRA_PROVISIONING_TIME_ZONE, optional

Called by the profile owner of a managed profile to enable widget providers from a given package to be available in the parent profile. As a result the user will be able to add widgets from the white-listed package running under the profile to a widget host which runs under the parent profile, for example the home screen. Note that a package may have zero or more provider components, where each component provides a different widget type.

Note: By default no widget provider package is white-listed.

Called by a profile owner or device owner to add a default intent handler activity for intents that match a certain intent filter. This activity will remain the default intent handler even if the set of potential event handlers for the intent filter changes and if the intent preferences are reset.

Return true if the given administrator component is currently active (enabled) in the system.

Called by device or profile owner to determine if a package is hidden.

Used to determine if a particular package has been registered as a Device Owner app. A device owner app is a special device admin that cannot be deactivated by the user, once activated as a device admin. It also cannot be uninstalled. To check if a particular package is currently registered as the device owner app, pass in the package name from getPackageName() to this method.

This is useful for device admin apps that want to check if they are also registered as the device owner app. The exact mechanism by which a device admin app is registered as a device owner app is defined by the setup process.

This function lets the caller know whether the given component is allowed to start the lock task mode.

Called by the profile owner of a managed profile to disable widget providers from a given package to be available in the parent profile. For this method to take effect the package should have been added via addCrossProfileWidgetProvider(android.content.ComponentName, String).

Note: By default no widget provider package is white-listed.

Called by a device owner to remove a user and all associated data. The primary user can not be removed.

Force a new device unlock password (the password needed to access the entire device, not for individual accounts) on the user. This takes effect immediately. The given password must be sufficient for the current password quality and length constraints as returned by getPasswordQuality(ComponentName) and getPasswordMinimumLength(ComponentName); if it does not meet these constraints, then it will be rejected and false returned. Note that the password may be a stronger quality (containing alphanumeric characters when the requested quality is only numeric), in which case the currently active quality will be increased to match.

Calling with a null or empty password will clear any existing PIN, pattern or password if the current password constraints allow it.

The calling device admin must have requested USES_POLICY_RESET_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Calling this from a managed profile will throw a security exception.

Called by a profile or device owner to set the application restrictions for a given target application running in the profile.

The provided Bundle consists of key-value pairs, where the types of values may be boolean, int, String, or String[].

The application restrictions are only made visible to the target application and the profile or device owner.

If the restrictions are not available yet, but may be applied in the near future, the admin can notify the target application of that by adding KEY_RESTRICTIONS_PENDING to the settings parameter.

The calling device admin must be a profile or device owner; if it is not, a security exception will be thrown.

Called by a device owner to set whether auto time is required. If auto time is required the user cannot set the date and time, but has to use network date and time.

Note: if auto time is required the user can still manually set the time zone.

The calling device admin must be a device owner. If it is not, a security exception will be thrown.

Called by an application that is administering the device to disable all cameras on the device, for this user. After setting this, no applications running as this user will be able to access any cameras on the device.

Calling this from a managed profile will throw a security exception.

Sets which packages may enter lock task mode.

Any packages that shares uid with an allowed package will also be allowed to activate lock task. This function can only be called by the device owner.

Called by profile or device owners to set the master volume mute on or off.

Setting this to a value greater than zero enables a built-in policy that will perform a device wipe after too many incorrect device-unlock passwords have been entered. This built-in policy combines watching for failed passwords and wiping the device, and requires that you request both USES_POLICY_WATCH_LOGIN and USES_POLICY_WIPE_DATA}.

To implement any other policy (e.g. wiping data for a particular application only, erasing or revoking credentials, or reporting the failure to a server), you should implement onPasswordFailed(Context, android.content.Intent) instead. Do not use this API, because if the maximum count is reached, the device will be wiped immediately, and your callback will not be invoked.

Called by an application that is administering the device to set the maximum time for user activity until the device will lock. This limits the length that the user can set. It takes effect immediately.

The calling device admin must have requested USES_POLICY_FORCE_LOCK to be able to call this method; if it has not, a security exception will be thrown.

Called by a device admin to set the password expiration timeout. Calling this method will restart the countdown for password expiration for the given admin, as will changing the device password (for all admins).

The provided timeout is the time delta in ms and will be added to the current time. For example, to have the password expire 5 days from now, timeout would be 5 * 86400 * 1000 = 432000000 ms for timeout.

To disable password expiration, a value of 0 may be used for timeout.

The calling device admin must have requested USES_POLICY_EXPIRE_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Note that setting the password will automatically reset the expiration time for all active admins. Active admins do not need to explicitly call this method in that case.

Called by an application that is administering the device to set the length of the password history. After setting this, the user will not be able to enter a new password that is the same as any password in the history. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested either PASSWORD_QUALITY_NUMERIC, PASSWORD_QUALITY_NUMERIC_COMPLEX PASSWORD_QUALITY_ALPHABETIC, or PASSWORD_QUALITY_ALPHANUMERIC with setPasswordQuality(ComponentName, int).

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by an application that is administering the device to set the minimum allowed password length. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested either PASSWORD_QUALITY_NUMERIC, PASSWORD_QUALITY_NUMERIC_COMPLEX, PASSWORD_QUALITY_ALPHABETIC, PASSWORD_QUALITY_ALPHANUMERIC, or PASSWORD_QUALITY_COMPLEX with setPasswordQuality(ComponentName, int).

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by an application that is administering the device to set the minimum number of letters required in the password. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested PASSWORD_QUALITY_COMPLEX with setPasswordQuality(ComponentName, int). The default value is 1.

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by an application that is administering the device to set the minimum number of lower case letters required in the password. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested PASSWORD_QUALITY_COMPLEX with setPasswordQuality(ComponentName, int). The default value is 0.

Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested PASSWORD_QUALITY_COMPLEX with setPasswordQuality(ComponentName, int). The default value is 0.

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by an application that is administering the device to set the minimum number of numerical digits required in the password. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested PASSWORD_QUALITY_COMPLEX with setPasswordQuality(ComponentName, int). The default value is 1.

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by an application that is administering the device to set the minimum number of symbols required in the password. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested PASSWORD_QUALITY_COMPLEX with setPasswordQuality(ComponentName, int). The default value is 1.

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by an application that is administering the device to set the minimum number of upper case letters required in the password. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value. This constraint is only imposed if the administrator has also requested PASSWORD_QUALITY_COMPLEX with setPasswordQuality(ComponentName, int). The default value is 0.

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by an application that is administering the device to set the password restrictions it is imposing. After setting this, the user will not be able to enter a new password that is not at least as restrictive as what has been set. Note that the current password will remain until the user has set a new one, so the change does not take place immediately. To prompt the user for a new password, use ACTION_SET_NEW_PASSWORD after setting this value.

Quality constants are ordered so that higher values are more restrictive; thus the highest requested quality constant (between the policy set here, the user's preference, and any other considerations) is the one that is in effect.

The calling device admin must have requested USES_POLICY_LIMIT_PASSWORD to be able to call this method; if it has not, a security exception will be thrown.

Called by a profile or device owner to set the permitted accessibility services. When set by a device owner or profile owner the restriction applies to all profiles of the user the device owner or profile owner is an admin for. By default the user can use any accessiblity service. When zero or more packages have been added, accessiblity services that are not in the list and not part of the system can not be enabled by the user.

Calling with a null value for the list disables the restriction so that all services can be used, calling with an empty list only allows the builtin system's services.

System accesibility services are always available to the user the list can't modify this.

Called by a profile or device owner to set the permitted input methods services. When set by a device owner or profile owner the restriction applies to all profiles of the user the device owner or profile owner is an admin for. By default the user can use any input method. When zero or more packages have been added, input method that are not in the list and not part of the system can not be enabled by the user. This method will fail if it is called for a admin that is not for the foreground user or a profile of the foreground user.

Calling with a null value for the list disables the restriction so that all input methods can be used, calling with an empty list disables all but the system's own input methods.

System input methods are always available to the user this method can't modify this.

Sets the enabled state of the profile. A profile should be enabled only once it is ready to be used. Only the profile owner can call this.

Sets the name of the profile. In the device owner case it sets the name of the user which it is called from. Only a profile owner or device owner can call this. If this is never called by the profile or device owner, the name will be set to default values.

Set a network-independent global HTTP proxy. This is not normally what you want for typical HTTP proxies - they are generally network dependent. However if you're doing something unusual like general internal filtering this may be useful. On a private network where the proxy is not accessible, you may break HTTP using this.

This method requires the caller to be the device owner.

This proxy is only a recommendation and it is possible that some apps will ignore it.

Designates a specific service component as the provider for making permission requests of a local or remote administrator of the user.

Only a profile owner can designate the restrictions provider.

Called by a device/profile owner to set whether the screen capture is disabled. Disabling screen capture also prevents the content from being shown on display devices that do not have a secure video output. See FLAG_SECURE for more details about secure surfaces and secure displays.

The calling device admin must be a device or profile owner. If it is not, a security exception will be thrown.

Called by profile or device owners to update Settings.Secure settings. Validation that the value of the setting is in the correct form for the setting type should be performed by the caller.

The settings that can be updated by a profile or device owner with this method are:

• DEFAULT_INPUT_METHOD
• INSTALL_NON_MARKET_APPS
• SKIP_FIRST_USE_HINTS

A device owner can additionally update the following settings:

• LOCATION_MODE

Called by an application that is administering the device to request that the storage system be encrypted.

When multiple device administrators attempt to control device encryption, the most secure, supported setting will always be used. If any device administrator requests device encryption, it will be enabled; Conversely, if a device administrator attempts to disable device encryption while another device administrator has enabled it, the call to disable will fail (most commonly returning ENCRYPTION_STATUS_ACTIVE).

This policy controls encryption of the secure (application data) storage area. Data written to other storage areas may or may not be encrypted, and this policy does not require or control the encryption of any other storage areas. There is one exception: If isExternalStorageEmulated() is true, then the directory returned by getExternalStorageDirectory() must be written to disk within the encrypted storage area.

Important Note: On some devices, it is possible to encrypt storage without requiring the user to create a device PIN or Password. In this case, the storage is encrypted, but the encryption key may not be fully secured. For maximum security, the administrator should also require (and check for) a pattern, PIN, or password.

Called by profile or device owners to change whether a user can uninstall a package.

Called by a device owner to switch the specified user to the foreground.

Uninstalls all custom trusted CA certificates from the profile. Certificates installed by means other than device policy will also be removed, except for system CA certificates.

Uninstalls the given certificate from trusted user CAs, if present.

Ask the user data be wiped. This will cause the device to reboot, erasing all user data while next booting up.

The calling device admin must have requested USES_POLICY_WIPE_DATA to be able to call this method; if it has not, a security exception will be thrown.
