But Now I want to stop the complete app when any kind of problem occurs(app crushes). Anyone can suggest me !!!!

Answer 1

you can kill the complete app and remove it from running app list throught pid with this lines :

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

Answer 2

Create a background service or Broadcast receiver and check with logged in parameter value ,if parameter value is null than call

Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_HOME);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);
        finish();`enter code here`
        System.exit(0);

Answer 3

Since this is possible for any crash at any time at any activity, one way is to catch all the exception in the defaultExceptionHandler and provide your bail-out mechanism there i.e. on any such exception, kill the app, reset the parameters, etc.

Link: how to implement uncaughtException android

http://developer.android.com/reference/java/lang/Thread.UncaughtExceptionHandler.html

A gist of the implementation

• Set a default exception handler to handle any crash that occurs anywhere.

  //Application.java

  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler(this));
  }
  

• Write an exception handler to handle any crash.

  // ExceptionHandler.java

  public class ExceptionHandler implements java.lang.Thread.UncaughtExceptionHandler { private final Activity ctx;

  public ExceptionHandler(Activity ctx) {
      this.ctx= ctx;
  }
  
  public void uncaughtException(Thread thread, Throwable exception) {
      // Send mail or upload exception details if required.
      // kill app.
      android.os.Process.killProcess(android.os.Process.myPid());
      System.exit(10);
  }
  

  }
