Android Kill Process

How to kill whole application in onne single click.. finish() is not working?? it redirects to tha previous activity...pls guide me. public void onClick(View arg0) {

Solution 1:

System.exit() does not kill your app if you have more than one activity on the stack

Use android.os.Process.killProcess(android.os.Process.myPid()); this way.

for sample

public void onBackPressed() {
    android.os.Process.killProcess(android.os.Process.myPid());
    super.onBackPressed();
}

For more detail see Is quitting an application frowned upon? , How to force stop my android application programmatically?

I hope this will help you.

Solution 2:

You can use this function to close your application

Process.killProcess( Process.myPid() ); 

Solution 3:

• Use startActivityForResult to start any activity.
• Write finish() in onActivityResult of the activity in which you are starting another activity if result == RESULT_CANCELLED.
• Finally use finish() at the point of exit.

Solution 4:

i think you want this

Intentintent=newIntent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);

Solution 5:

Finish ()

Added in API level 1 Call this when your activity is done and should be closed. The Activity Result is propagated back to whoever launched you via onActivityResult().

you must use System.exit() to kill your application on a click to directly close the activity.

Why finish() is not working for you ?

Take an example where Activity A had called Activity B and when you call finish() on your activity B if finish the activity but as Activity A had given him called and it is a previous activity it returns back you to Activity A screen

What you can do?

1. You can call System.exit() - It will directly kill the application wherever it is called from it does not matter.

2. Use Process.killProcess(your process id);

3. Start the home activity by killing your current activity by using finish() and then call

   Intentintent=newIntent(Intent.ACTION_MAIN);
   intent.addCategory(Intent.CATEGORY_HOME);
   intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   startActivity(intent);
