android task kill

I want to kill all tasks that run in android like task killer... What I have done until now is:

ActivityManager manager =  (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
    List<RunningAp开发者_如何转开发pProcessInfo> activityes = ((ActivityManager) manager).getRunningAppProcesses();

    for (int i = 0; i < activityes.size(); i++){

        Log.e("APP: "+i, activityes.get(0).processName);

        if (!activityes.get(0).processName.equals("app.android.myapp")){
            Process.killProcess(activityes.get(0).pid);
        }

    }

The problem with the code is that it returns in the activityes list only my app for 12 times. And no task is being killed...

Can somebody help me please? Thank you!

You do not have the rights to kill other processes; hence, killProcess() does not work for your app.

You're using 0 (zero) instead of i inside your loop.

for (int i = 0; i < activityes.size(); i++){

    Log.e("APP: "+i, activityes.get(i).processName);

    if (!activityes.get(i).processName.equals("app.android.myapp")){
        Process.killProcess(activityes.get(i).pid);
    }

}

Cheers

You can kill the current process on back pressed using the following code:

public void onBackPressed() {
    super.onBackPressed();
    int pid = android.os.Process.myPid();
    android.os.Process.killProcess(pid);

You can try this to kill your task or app:

ActivityManager am = (ActivityManager) ctx
                .getSystemService(ctx.ACTIVITY_SERVICE);
am.killBackgroundProcesses(packageName);

this works for 2.2 and up.

1- Add to manifest

<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES"/>

2 - In your code

Runtime.getRuntime().exec("adb shell killall com.example.app");

note that your app need to have access to adb shell (system app)
