I think you have to exclusively exit the application. After exiting the application check the task manager, if it is still enlisted in the running application section then you have to end the process.

You can check the following code:

// This you have to insert inside the exit button click event
    Intent intent = new Intent(Intent.ACTION_MAIN);
                    intent.addCategory(Intent.CATEGORY_HOME);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    startActivity(intent);
                    onQuitPressed(); 

//This is the onQuitPressed method

//to remove application from task manager
    public void onQuitPressed() {

        int pid = android.os.Process.myPid();
        android.os.Process.killProcess(pid);
    }
