高通Android 12/13冻结应用

最近开发SDK遇到冻结应用需求，于是简单记录下。总体而言比较简单，调用系统接口实现此功能。

涉及类与方法

IPackageManager .aidl #  * As per {@link android.content.pm.PackageManager#setApplicationEnabledSetting}.*/@UnsupportedAppUsagevoid setApplicationEnabledSetting(in String packageName, in int newState, int flags,int userId, String callingPackage);PackageManager.java # setApplicationEnabledSettingPackageManagerService.java  # setApplicationEnabledSetting # setEnabledSetting

1、IPackageManager.aidl

代码路径 /frameworks/base/core/java/android/content/pm/IPackageManager.aidl

/*** As per {@link android.content.pm.PackageManager#setApplicationEnabledSetting}.*/@UnsupportedAppUsagevoid setApplicationEnabledSetting(in String packageName, in int newState, int flags,int userId, String callingPackage);

2、PackageManagerService.java

代码路径 /frameworks/base/core/java/android/content/pm/PackageManagerService.java

 @Overridepublic void setComponentEnabledSetting(ComponentName componentName,int newState, int flags, int userId) {if (!mUserManager.exists(userId)) return;setEnabledSetting(componentName.getPackageName(),componentName.getClassName(), newState, flags, userId, null);}private void setEnabledSetting(final String packageName, String className, int newState,final int flags, int userId, String callingPackage) {if (!(newState == COMPONENT_ENABLED_STATE_DEFAULT|| newState == COMPONENT_ENABLED_STATE_ENABLED|| newState == COMPONENT_ENABLED_STATE_DISABLED|| newState == COMPONENT_ENABLED_STATE_DISABLED_USER|| newState == COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED)) {throw new IllegalArgumentException("Invalid new component state: "+ newState);}PackageSetting pkgSetting;final int callingUid = Binder.getCallingUid();final int permission;if (callingUid == Process.SYSTEM_UID) {permission = PackageManager.PERMISSION_GRANTED;} else {permission = mContext.checkCallingOrSelfPermission(android.Manifest.permission.CHANGE_COMPONENT_ENABLED_STATE);}enforceCrossUserPermission(callingUid, userId, false /* requireFullPermission */,true /* checkShell */, "set enabled");final boolean allowedByPermission = (permission == PackageManager.PERMISSION_GRANTED);boolean sendNow = false;boolean isApp = (className == null);final boolean isCallerInstantApp = (getInstantAppPackageName(callingUid) != null);String componentName = isApp ? packageName : className;ArrayList<String> components;// readersynchronized (mLock) {pkgSetting = mSettings.getPackageLPr(packageName);if (pkgSetting == null) {if (!isCallerInstantApp) {if (className == null) {throw new IllegalArgumentException("Unknown package: " + packageName);}throw new IllegalArgumentException("Unknown component: " + packageName + "/" + className);} else {// throw SecurityException to prevent leaking package informationthrow new SecurityException("Attempt to change component state; "+ "pid=" + Binder.getCallingPid()+ ", uid=" + callingUid+ (className == null?

if it has been a "reasonably long time" since the// service started, send the broadcast with a delay of one second to avoid// delayed reactions from the receiver, else keep the default ten second delay// to avoid extreme thrashing on service startup.final long broadcastDelay = SystemClock.uptimeMillis() > mServiceStartWithDelay? BROADCAST_DELAY: BROADCAST_DELAY_DURING_STARTUP;mHandler.sendEmptyMessageDelayed(SEND_PENDING_BROADCAST, broadcastDelay);}}}final long callingId = Binder.clearCallingIdentity();try {if (sendNow) {int packageUid = UserHandle.getUid(userId, pkgSetting.appId);sendPackageChangedBroadcast(packageName,(flags & PackageManager.DONT_KILL_APP) != 0, components, packageUid, null);}} finally {Binder.restoreCallingIdentity(callingId);}}

3、PackageManager.java 

代码路径 /frameworks/base/core/java/android/content/pm/PackageManager.java

     * Set the enabled setting for an application* This setting will override any enabled state which may have been set by the application in* its manifest.  It also overrides the enabled state set in the manifest for any of the* application's components.  It does not override any enabled state set by* {@link #setComponentEnabledSetting} for any of the application's components.** @param packageName The package name of the application to enable* @param newState The new enabled state for the application.* @param flags Optional behavior flags.*/@RequiresPermission(value = android.Manifest.permission.CHANGE_COMPONENT_ENABLED_STATE,conditional = true)public abstract void setApplicationEnabledSetting(@NonNull String packageName,@EnabledState int newState, @EnabledFlags int flags);

4、代码调用 示例 packageName就是当前需要冻结应用包名 ，冻结标志位PackageManager.COMPONENT_ENABLED_STATE_DISABLED_USER                                            

IPackageManager iPackageManager = IPackageManager.Stub.asInterface(ServiceManager.getService("package"));
iPackageManager.setApplicationEnabledSetting(packageName, PackageManager.COMPONENT_ENABLED_STATE_ENABLE, 0, 0, "shell:" + android.os.Process.myUid());

5、测试之后在Settings里面查看冻结应用是否显示停用，如果是表面冻结应用成功。解冻也是类似只是设置标志位不一样， PackageManager.COMPONENT_ENABLED_STATE_ENABLED。

try {IPackageManager iPackageManager = IPackageManager.Stub.asInterface(ServiceManager.getService("package"));if (iPackageManager != null) {iPackageManager.setApplicationEnabledSetting(packageName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED,0, 0, "shell:" + android.os.Process.myUid());Log.e("unfreezeApp", "freeze PackageName=" + packageName);}} catch (RemoteException e) {Log.e("unfreezeApp", "freeze PackageManager RemoteException=" + e.getMessage());}

到这里基本结束了。转载请注册出处高通Android 12/13冻结应用-CSDN博客，谢谢！

补充标志位状态值

COMPONENT_ENABLED_STATE_DEFAULT, //启用APP或组件，忽略manifest的定义。 COMPONENT_ENABLED_STATE_ENABLED, //禁用APP或组件，忽略manifest的定义。 COMPONENT_ENABLED_STATE_DISABLED, //以用户身份禁用APP，忽略manifest的定义。不能用于组件操作。 COMPONENT_ENABLED_STATE_DISABLED_USER, //禁用APP直到用户想用才出现。也就是说，正常情况下，用户看不到（比如在Launcher上）；但是特殊情况下，用户还是能看到并选择到（比如输入法APP）。不能用于组件操作。 COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED,
