Public methods

void addPackageToPreferred(String packageName)

This method is deprecated. This function no longer does anything. It is the platform's responsibility to assign preferred activities and this cannot be modified directly. To determine the activities resolved by the platform, use resolveActivity(Intent, ResolveInfoFlags) or queryIntentActivities(Intent, ResolveInfoFlags). To configure an app to be responsible for a particular role and to check current role holders, see RoleManager.

boolean addPermission(PermissionInfo info)

Add a new dynamic permission to the system.

boolean addPermissionAsync(PermissionInfo info)

addPackageToPreferred

Added in API level 1 
public void addPackageToPreferred (String packageName)

This method is deprecated.
This function no longer does anything. It is the platform's responsibility to assign preferred activities and this cannot be modified directly. To determine the activities resolved by the platform, use resolveActivity(Intent, ResolveInfoFlags) or queryIntentActivities(Intent, ResolveInfoFlags). To configure an app to be responsible for a particular role and to check current role holders, see RoleManager.

Parameters
packageName String: This value cannot be null.

addPermission

Added in API level 1 
public boolean addPermission (PermissionInfo info)

Add a new dynamic permission to the system. For this to work, your package must have defined a permission tree through the <permission-tree> tag in its manifest. A package can only add permissions to trees that were defined by either its own package or another with the same user id; a permission is in a tree if it matches the name of the permission tree + ".": for example, "com.foo.bar" is a member of the permission tree "com.foo".

It is good to make your permission tree name descriptive, because you are taking possession of that entire set of permission names. Thus, it must be under a domain you control, with a suffix that will not match any normal permissions that may be declared in any applications that are part of that domain.

New permissions must be added before any .apks are installed that use those permissions. Permissions you add through this method are remembered across reboots of the device. If the given permission already exists, the info you supply here will be used to update it.

Parameters
info PermissionInfo: Description of the permission to be added.
This value cannot be null.
Returns
boolean Returns true if a new permission was created, false if an existing one was updated.

addPermissionAsync

Added in API level 8
Deprecated in API level 24 
public boolean addPermissionAsync (PermissionInfo info)

Like addPermission(PermissionInfo) but asynchronously persists the package manager state after returning from the call, allowing it to return quicker and batch a series of adds at the expense of no guarantee the added permission will be retained if the device is rebooted before it is written.

Parameters
info PermissionInfo: This value cannot be null.
Returns
boolean

addPreferredActivity

Added in API level 1 
public void addPreferredActivity (IntentFilter filter, 
                int match, 
                ComponentName[] set, 
                ComponentName activity)

This method is deprecated.
This function no longer does anything. It is the platform's responsibility to assign preferred activities and this cannot be modified directly. To determine the activities resolved by the platform, use resolveActivity(Intent, ResolveInfoFlags) or queryIntentActivities(Intent, ResolveInfoFlags). To configure an app to be responsible for a particular role and to check current role holders, see RoleManager.

Add a new preferred activity mapping to the system. This will be used to automatically select the given activity component when Context.startActivity() finds multiple matching activities and also matches the given filter.

Parameters
filter IntentFilter: The set of intents under which this activity will be made preferred.
This value cannot be null.
match int: The IntentFilter match category that this preference applies to.
set ComponentName: The set of activities that the user was picking from when this preference was made.
This value may be null.
activity ComponentName: The component name of the activity that is to be preferred.
This value cannot be null.

addWhitelistedRestrictedPermission

public boolean addWhitelistedRestrictedPermission (String packageName, 
                String permission, 
                int whitelistFlags)

Adds a whitelisted restricted permission for an app.

Permissions can be hard restricted which means that the app cannot hold them or soft restricted where the app can hold the permission but in a weaker form. Whether a permission is hard restricted or soft restricted depends on the permission declaration. Whitelisting a hard restricted permission allows for the to hold that permission and whitelisting a soft restricted permission allows the app to hold the permission in its full, unrestricted form.

    There are four whitelists:
  1. one for cases where the system permission policy whitelists a permission This list corresponds to the FLAG_PERMISSION_WHITELIST_SYSTEM flag. Can only be modified by pre-installed holders of a dedicated permission.
  2. one for cases where the system whitelists the permission when upgrading from an OS version in which the permission was not restricted to an OS version in which the permission is restricted. This list corresponds to the FLAG_PERMISSION_WHITELIST_UPGRADE flag. Can be modified by pre-installed holders of a dedicated permission. The installer on record can only remove permissions from this whitelist.
  3. one for cases where the installer of the package whitelists a permission. This list corresponds to the FLAG_PERMISSION_WHITELIST_INSTALLER flag. Can be modified by pre-installed holders of a dedicated permission or the installer on record.

You need to specify the whitelists for which to set the whitelisted permissions which will clear the previous whitelisted permissions and replace them with the provided ones.

Note: In retrospect it would have been preferred to use more inclusive terminology when naming this API. Similar APIs added will refrain from using the term "whitelist".

Parameters
packageName String: The app for which to get whitelisted permissions.
This value cannot be null.
permission String: The whitelisted permission to add.
This value cannot be null.
whitelistFlags int: The whitelists to which to add. Passing multiple flags updates all specified whitelists.
Value is either 0 or a combination of the following:
Returns
boolean Whether the permission was added to the whitelist.

canRequestPackageInstalls

Added in API level 26
Deprecated in API level 24 
public boolean canRequestPackageInstalls ()

Checks whether the calling package is allowed to request package installs through package installer. Apps are encouraged to call this API before launching the package installer via intent Intent.ACTION_INSTALL_PACKAGE. Starting from Android O, the user can explicitly choose what external sources they trust to install apps on the device. If this API returns false, the install request will be blocked by the package installer and a dialog will be shown to the user with an option to launch settings to change their preference. An application must target Android O or higher and declare permission Manifest.permission.REQUEST_INSTALL_PACKAGES in order to use this API.

Returns
boolean true if the calling package is trusted by the user to request install packages on the device, false otherwise.

canonicalToCurrentPackageNames

Added in API level 8
Deprecated in API level 24 
public String[] canonicalToCurrentPackageNames (String[] names)

Map from a packages canonical name to the current name in use on the device.

Parameters
names String: Array of new names to be mapped.
This value cannot be null.
Returns
String[] Returns an array of the same size as the original, containing the current name for each package.

checkPermission

Added in API level 1 
public int checkPermission (String permName, 
                String pkgName)

Check whether a particular package has been granted a particular permission.

Note: This API returns the underlying permission state as-is and is mostly intended for permission managing system apps. To perform an access check for a certain app, please use the Context.checkPermission APIs instead.

Parameters
permName String: The name of the permission you are checking for.
This value cannot be null.
pkgName String: The name of the package you are checking against.
This value cannot be null.
Returns
int If the package has the permission, PERMISSION_GRANTED is returned. If it does not have the permission, PERMISSION_DENIED is returned.
Value is one of the following:

checkSignatures

Added in API level 1 
public int checkSignatures (String pkg1, 
                String pkg2)

Compare the signatures of two packages to determine if the same signature appears in both of them. If they do contain the same signature, then they are allowed special privileges when working with each other: they can share the same user-id, run instrumentation against each other, etc.

Parameters
pkg1 String: First package name whose signature will be compared.
This value cannot be null.
pkg2 String: Second package name whose signature will be compared.
This value cannot be null.
Returns
int Returns an integer indicating whether all signatures on the two packages match. The value is >= 0 (SIGNATURE_MATCH) if all signatures match or < 0 if there is not a match (SIGNATURE_NO_MATCH or SIGNATURE_UNKNOWN_PACKAGE).
Value is one of the following:

checkSignatures

Added in API level 5
Deprecated in API level 24 
public int checkSignatures (int uid1, 
                int uid2)

Like checkSignatures(String,String), but takes UIDs of the two packages to be checked. This can be useful, for example, when doing the check in an IPC, where the UID is the only identity available. It is functionally identical to determining the package associated with the UIDs and checking their signatures.

Parameters
uid1 int: First UID whose signature will be compared.
uid2 int: Second UID whose signature will be compared.
Returns
int Returns an integer indicating whether all signatures on the two packages match. The value is >= 0 (SIGNATURE_MATCH) if all signatures match or < 0 if there is not a match (SIGNATURE_NO_MATCH or SIGNATURE_UNKNOWN_PACKAGE).
Value is one of the following:

clearInstantAppCookie

Added in API level 26 
public void clearInstantAppCookie ()

Clears the instant application cookie for the calling app.

clearPackagePreferredActivities

Added in API level 1 
public void clearPackagePreferredActivities (String packageName)

extendVerificationTimeout

Added in API level 17
Deprecated in API level 24 
public void extendVerificationTimeout (int id, 
                int verificationCodeAtTimeout, 
                long millisecondsToDelay)

Allows a package listening to the package verification broadcast to extend the default timeout for a response and declare what action to perform after the timeout occurs. The response must include the verificationCodeAtTimeout which is one of PackageManager.VERIFICATION_ALLOW or PackageManager.VERIFICATION_REJECT. This method can be called multiple times, but the total amount of time extension time will be limited to PackageManager.MAXIMUM_VERIFICATION_TIMEOUT. If the method is called multiple times with different verificationCodeAtTimeout, then previous verificationCodeAtTimeout will be ignored and only the latest one will take effect. If this method is called after calling PackageManager.verifyPendingInstall, it may nullify the result set by verifyPendingInstall.

Parameters
id int: pending package identifier as passed via the PackageManager.EXTRA_VERIFICATION_ID Intent extra.
verificationCodeAtTimeout int: either PackageManager.VERIFICATION_ALLOW or PackageManager.VERIFICATION_REJECT. If verificationCodeAtTimeout is neither PackageManager.VERIFICATION_ALLOW or PackageManager.VERIFICATION_REJECT, then verificationCodeAtTimeout will default to PackageManager.VERIFICATION_REJECT.
millisecondsToDelay long: the amount of time requested for the timeout. Must be positive and less than PackageManager.MAXIMUM_VERIFICATION_TIMEOUT. If millisecondsToDelay is out of bounds, millisecondsToDelay will be set to the closest in bounds value; namely, 0 or PackageManager.MAXIMUM_VERIFICATION_TIMEOUT.
