Android通过反射实现强制停止应用程序的方法

本文实例讲述了Android通过反射实现强制停止应用程序的方法。分享给大家供大家参考，具体如下：

private ActivityManager manager;
private List runningProcesses;
private String packName;
private PackageManager pManager;
@Override
public void onReceive(Context context, Intent intent) {
    pManager = context.getPackageManager();
    manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    killOthers(context);
}

private void killOthers(Context context) {
    runningProcesses = manager.getRunningAppProcesses();
    for (RunningAppProcessInfo runningProcess : runningProcesses) {
      try {
 packName = runningProcess.processName;
 ApplicationInfo applicationInfo = pManager.getPackageInfo(packName, 0).applicationInfo;
 if (!"com.asms".equals(packName)&&filterApp(applicationInfo)) {
   forceStopPackage(packName,context);
   System.out.println(packName+"JJJJJJ");
 }
      }catch(Exception e){
 e.printStackTrace();
      }
    }
}

private void forceStopPackage(String pkgName,Context context) throws Exception{
    ActivityManager am = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
    Method method = Class.forName("android.app.ActivityManager").getMethod("forceStopPackage", String.class);
    method.invoke(am, pkgName);
}

public boolean filterApp(ApplicationInfo info) {
    if ((info.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
      return true;
    } else if ((info.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {
      return true;
    }
    return false;
}

说明：如果是在Activity中将onReceiver方法换成onCreate方法即可。

2.需要在AndroidManifest.xml 把package的userid设置为system
