The task manager on Android 2.2 kills the process's API

Recently, I want to create a task manager on the Android 2.2 platform. The former API: restartpackage is invalid on Android 2.2.

The restartpackage API is valid on platforms 1.5 and 1.6: activitymanager. restartpackage (pakagename );

The test failed multiple times on 2.2. Later, I checked the framework and found that it was blocked by Google? No alternative API is found.

 

 

 

If you have system permissions,
1. Use the following code

 

 

@SuppressWarnings({ "rawtypes" })         private boolean killProcessByPkg(String pkgName){                 Class c;                 try {                         c = Class.forName("android.app.ActivityManagerNative");                         Method getDefaultMethod = c.getMethod("getDefault");                         getDefaultMethod.setAccessible(true);                         Object nativeManager = getDefaultMethod.invoke(null);                         c = nativeManager.getClass();                         Method forceStopPackageMethod = c.getMethod("forceStopPackage", String.class);                         forceStopPackageMethod.setAccessible(true);                         forceStopPackageMethod.invoke(nativeManager, pkgName);                 } catch (ClassNotFoundException e) {                         e.printStackTrace();                 } catch (SecurityException e) {                         e.printStackTrace();                 } catch (NoSuchMethodException e) {                         e.printStackTrace();                 } catch (IllegalArgumentException e) {                         e.printStackTrace();                 } catch (IllegalAccessException e) {                         e.printStackTrace();                 } catch (InvocationTargetException e) {                         e.printStackTrace();                 }                 return true;         }

 

 

 

2. Add permission to the manifist file:

android.permission.FORCE_STOP_PACKAGES

3. Create an android. mk file.

 

LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) #LOCAL_MODULE_TAGS := optional LOCAL_SRC_FILES := $(call all-java-files-under, src) LOCAL_PACKAGE_NAME := TestKillProcess LOCAL_CERTIFICATE := platform include $(BUILD_PACKAGE) # Use the folloing include to make our test apk. include $(call all-makefiles-under,$(LOCAL_PATH))

 

 

4. Compile and use the APK File

ADB install <your APK File>

 

If the installation is successful, you have system permissions and can use it.
I tried emulator successfully.

If you do not have system permissions,

 

Private activitymanager am;
 
AM = (activitymanager) This. getsystemservice (service. activity_service );
 
Am. killbackgroundprocesses (packagename );

 

 

Yes, but make sure that the process you want to kill is in the onstop state.
