Listener is not working

Have you made sure that the code compiles without errors?

yap, when i pass the right id which i know as sucess  it do not give me any message, but when i pass the wrong id it gives the right result as fails. what mistake i am doing
MainActive.txt

In the first MainActivity.txt it iooks like the the if(success) brackets are not correct, two left brackets in a row, plus you might have two extra brackets surrounding the Toast code, this is your code:
  if(success) {

    {
         
         Toast toast3 = Toast.makeText(MainActive.this, message1, Toast.LENGTH_SHORT);
       toast3.show();      
    }                                                    
                                              
   }

change it to this

  if(success) {
        String message1 = "success";
        Toast toast3 = Toast.makeText(MainActive.this, message1, Toast.LENGTH_SHORT);
       toast3.show();      
    }

If that isn't the solution, perhaps the method MMAdCachingCompleted is not being called when you pass the right ID. You can further troubleshoot the code by placing the Toast message inside the MMAdCachingCompleted at the top of the method outside of any If Else statement to see if it's being called when you know you pass the right ID. The result of this test will tell you something.

public void MMAdCachingCompleted(MMAdView fetchCheckDisplayAdView, boolean success)
{
      String message1 = "Testing MMAdCachingCompleted";
      Toast toast3 = Toast.makeText(MainActive.this, message1, Toast.LENGTH_SHORT);
       toast3.show();  

}

Ok , what is the right id you are passing ?

91776

But in this line , you are checking for a boolean , not an id :

public void MMAdCachingCompleted(MMAdView fetchCheckDisplayAdView, boolean success)
			{
  				if(success) {

Select allOpen in new window

Yes i tried this method also, it did not work

public void MMAdReturned(MMAdView fetchCheckDisplayAdView)
      {
            Log.i(TAG, "(" + adview.getId() + ") View Success");
      }

The id 91776 simply is not turning success to true .
Change if(success) to if(true) and see . It will shows where the code is 'jumping off'

I did that but it still jumps out of this loop from this statements below to out of the loop
"fetchCheckDisplayAdView.setListener(new BasicMMAdListener(){"

if(true){
                           String message2 = "pass";
                      Toast toast2 = Toast.makeText(MainActive.this, message2, Toast.LENGTH_SHORT);
                      toast2.show();
                      
                     Log.i(TAG, " Ad (" + fetchCheckDisplayAdView.getId() + ") caching completed successfully: " + success);
               }

As someone else suggested above , remove the extra { } pair just after if(success) , compile and run

Hi roy_sanu,

How do you know it jumps out of the loop or how can you tell it was in the loop, then jumped out?
