Constants
CERT_INPUT_RAW_X509
public static final int CERT_INPUT_RAW_X509
Certificate input bytes: the input bytes represent an encoded X.509 Certificate which could
be generated using an CertificateFactory
Constant Value: 0 (0x00000000)
CERT_INPUT_SHA256
public static final int CERT_INPUT_SHA256
Certificate input bytes: the input bytes represent the SHA256 output of an encoded X.509 Certificate.
Constant Value: 1 (0x00000001)
COMPONENT_ENABLED_STATE_DEFAULT
public static final int COMPONENT_ENABLED_STATE_DEFAULT
Flag for setApplicationEnabledSetting(String, int, int)
and
setComponentEnabledSetting(ComponentName, int, int)
: This
component or application is in its default enabled state (as specified in
its manifest).
Explicitly setting the component state to this value restores it's enabled state to whatever is set in the manifest.
Constant Value: 0 (0x00000000)
COMPONENT_ENABLED_STATE_DISABLED
public static final int COMPONENT_ENABLED_STATE_DISABLED
Flag for setApplicationEnabledSetting(String, int, int)
and setComponentEnabledSetting(ComponentName, int, int)
: This
component or application has been explicitly disabled, regardless of
what it has specified in its manifest.
Constant Value: 2 (0x00000002)
COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED
public static final int COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED
Flag for setApplicationEnabledSetting(String, int, int)
only: This
application should be considered, until the point where the user actually
wants to use it. This means that it will not normally show up to the user
(such as in the launcher), but various parts of the user interface can
use GET_DISABLED_UNTIL_USED_COMPONENTS
to still see it and allow
the user to select it (as for example an IME, device admin, etc). Such code,
once the user has selected the app, should at that point also make it enabled.
This option currently can not be used with
setComponentEnabledSetting(ComponentName, int, int)
.
Constant Value: 4 (0x00000004)
COMPONENT_ENABLED_STATE_DISABLED_USER
public static final int COMPONENT_ENABLED_STATE_DISABLED_USER
Flag for setApplicationEnabledSetting(String, int, int)
only: The
user has explicitly disabled the application, regardless of what it has
specified in its manifest. Because this is due to the user's request,
they may re-enable it if desired through the appropriate system UI. This
option currently cannot be used with
setComponentEnabledSetting(ComponentName, int, int)
.
Constant Value: 3 (0x00000003)
COMPONENT_ENABLED_STATE_ENABLED
public static final int COMPONENT_ENABLED_STATE_ENABLED
Flag for setApplicationEnabledSetting(String, int, int)
and setComponentEnabledSetting(ComponentName, int, int)
: This
component or application has been explictily enabled, regardless of
what it has specified in its manifest.
Constant Value: 1 (0x00000001)
DONT_KILL_APP
public static final int DONT_KILL_APP
Flag parameter for
setComponentEnabledSetting(android.content.ComponentName, int, int)
to indicate
that you don't want to kill the app containing the component. Be careful when you set this
since changing component states can make the containing application's behavior unpredictable.
Constant Value: 1 (0x00000001)
EXTRA_VERIFICATION_ID
public static final String EXTRA_VERIFICATION_ID
Extra field name for the ID of a package pending verification. Passed to
a package verifier and is used to call back to
verifyPendingInstall(int, int)
Constant Value: "android.content.pm.extra.VERIFICATION_ID"
EXTRA_VERIFICATION_RESULT
public static final String EXTRA_VERIFICATION_RESULT
Extra field name for the result of a verification, either
VERIFICATION_ALLOW
, or VERIFICATION_REJECT
.
Passed to package verifiers after a package is verified.
Constant Value: "android.content.pm.extra.VERIFICATION_RESULT"
FEATURE_ACTIVITIES_ON_SECONDARY_DISPLAYS
public static final String FEATURE_ACTIVITIES_ON_SECONDARY_DISPLAYS
Feature for getSystemAvailableFeatures()
and hasSystemFeature(String)
:
The device supports running activities on secondary displays.
Constant Value: "android.software.activities_on_secondary_displays"

Public constructors
Public methods
addPackageToPreferred
public abstract void addPackageToPreferred (String packageName)
This method was deprecated
in API level 7.
This function no longer does anything; it was an old
approach to managing preferred activities, which has been superseded
by (and conflicts with) the modern activity-based preferences.
Parameters | |
---|---|
packageName |
String |
addPermission
public abstract 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. |
Returns | |
---|---|
boolean |
Returns true if a new permission was created, false if an existing one was updated. |
Throws | |
---|---|
SecurityException |
if you are not allowed to add the given permission name. |
See also:
addPermissionAsync
public abstract 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 |
Returns | |
---|---|
boolean |
addPreferredActivity
public abstract void addPreferredActivity (IntentFilter filter, int match, ComponentName[] set, ComponentName activity)
This method was deprecated
in API level 8.
This is a protected API that should not have been available
to third party applications. It is the platform's responsibility for
assigning preferred activities and this cannot be directly modified.
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. |
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. |
activity |
ComponentName : The component name of the activity that is to be
preferred.
|
canRequestPackageInstalls
public abstract 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
public abstract 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. |
Returns | |
---|---|
String[] |
Returns an array of the same size as the original, containing the current name for each package. |
checkPermission
public abstract int checkPermission (String permName, String pkgName)
Check whether a particular package has been granted a particular permission.
Parameters | |
---|---|
permName |
String : The name of the permission you are checking for. |
pkgName |
String : The name of the package you are checking against. |
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 |
See also:
checkSignatures
public abstract int checkSignatures (String pkg1, String pkg2)

pkg1 |
String : First package name whose signature will be compared. |
pkg2 |
String : Second package name whose signature will be compared. |
Returns | |
---|---|
int |

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 |
See also:
checkSignatures
public abstract 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 |

action to perform after the timeout occurs. The response must include
the verificationCodeAtTimeout
which is one of
VERIFICATION_ALLOW
or
VERIFICATION_REJECT
.
This method may only be called once per package id. Additional calls
will have no effect.
Parameters | |
---|---|
id |
int : pending package identifier as passed via the
EXTRA_VERIFICATION_ID Intent extra. |
verificationCodeAtTimeout |
int : either
VERIFICATION_ALLOW or
VERIFICATION_REJECT . If

hasSigningCertificate
public boolean hasSigningCertificate (int uid, byte[] certificate, int type)
Searches the set of signing certificates by which the package(s) for the given uid has proven
to have been signed. For multiple packages sharing the same uid, this will return the
signing certificates found in the signing history of the "newest" package, where "newest"
indicates the package with the newest signing certificate in the shared uid group. This
method should be used instead of getPackageInfo
with GET_SIGNATURES
since it takes into account the possibility of signing certificate rotation, except in the
case of packages that are signed by multiple certificates, for which signing certificate
rotation is not supported. This method is analogous to using getPackagesForUid
followed by getPackageInfo
with GET_SIGNING_CERTIFICATES
, selecting the
PackageInfo
of the newest-signed bpackage , and finally searching through the
resulting signingInfo
field to see if the desired certificate is there.
Parameters | |

hasSigningCertificate
public boolean hasSigningCertificate (String packageName, byte[] certificate, int type)
Searches the set of signing certificates by which the given package has proven to have been
signed. This should be used instead of getPackageInfo
with GET_SIGNATURES
since it takes into account the possibility of signing certificate rotation, except in the
case of packages that are signed by multiple certificates, for which signing certificate
rotation is not supported. This method is analogous to using getPackageInfo
with
GET_SIGNING_CERTIFICATES
and then searching through the resulting signingInfo
field to see if the desired certificate is present.
Parameters | |
---|---|
packageName |
String : package whose signing certificates to check |
certificate |
byte : signing certificate for which to search |
type |
int : representation of the certificate Value is |

if the available feature version is greater than or equal to the
requested version.
Parameters | |
---|---|
name |
String |
version |
int |
Returns | |
---|---|
boolean |
Returns true if the devices supports the feature, else false. |
isInstantApp
public abstract boolean isInstantApp ()
Gets whether this application is an instant app.
Returns | |
---|---|
boolean |
Whether caller is an instant app. |
isInstantApp
public abstract boolean isInstantApp (String packageName)
Gets whether the given package is an instant app.
Parameters | |
---|---|
packageName |
String : The package to check |
Returns | |
---|---|
boolean |
Whether the given package is an instant app. |
isPackageSuspended
public boolean isPackageSuspended ()
Apps can query this to know if they have been suspended. A system app with the permission
android.permission.SUSPEND_APPS
can put any app on the device into a suspended state.
While in this state, the application's notifications will be hidden, any of its started activities will be stopped and it will not be able to show toasts or dialogs or ring the device. When the user tries to launch a suspended app, the system will, instead, show a dialog to the user informing them that they cannot use this app while it is suspended.
When an app is put into this state, the broadcast action
Intent.ACTION_MY_PACKAGE_SUSPENDED
will be delivered to any of its broadcast
receivers that included this action in their intent-filters, including manifest
receivers. Similarly, a broadcast action Intent.ACTION_MY_PACKAGE_UNSUSPENDED
is delivered when a previously suspended app is taken out of this state.
Returns | |
---|---|
boolean |
true if the calling package has been suspended, false otherwise. |
isPermissionRevokedByPolicy
public abstract boolean isPermissionRevokedByPolicy (String permName, String pkgName)

permName |
String : The name of the permission you are checking for.This value must never be |
pkgName |
String : The name of the package you are checking against.This value must never be |
