does anyone has an idea why the following toast is not appearing ? the log is printed and another toast in the same function is also working

    if (searchType.equals("ByName")){
        // get the extra from the intent:
        String query = intent.getStringExtra("query");      
            if (!searchByName(query)){
                Toast.makeText(getApplicationContext(), "No results for this search",
                        Toast.LENGTH_LONG).show();  
                Log.d(TAG, "return status true/false -->" + searchByName(query));
            }           
    }

any help will be appreciated

i'm attaching the Log, i had to remove some lines since it's too long... here is the Log:

有帮助吗？

解决方案

I think its a bug in Android Framework. Whenever you are try to make or display a Toast out of Application Main Thread. Mostly possible with IntentService. Always be sure your Toast goes in Application Main Thread.

Look at Below Workaround. This all code goes in your Service.

Handler Declaration.

Handler handler = null;

and in Constructor of your Service

handler  = new Handler();

Method to call for display Toast.

public void showToast(String message, Context context){
        handler.post(new CustomToast(message, context));
    }

CostomToast 

private class CustomToast implements Runnable{
          String mText;
          Context mContext;

  public CustomToast(String text, Context context){
            mText = text;
            mContext = context;
  }

   public void run(){
            Toast.makeText(mContext, mText, Toast.LENGTH_LONG).show();
  }
