below is the code in my first class

Flashbar.Builder(context)
                .gravity(Flashbar.Gravity.TOP)
                .duration(5000)
                .title("Error!!")
                .message(mesg)
                .icon(R.drawable.logo)
                .backgroundDrawable(R.drawable.error_bg)
                .titleColorRes(R.color.white)
                .messageColorRes(R.color.white)
                .enterAnimation(FlashAnim.with(context)
                        .animateBar()
                        .duration(750)
                        .alpha()
                        .overshoot())
                .exitAnimation(FlashAnim.with(context)
                        .animateBar()
                        .duration(400)
                        .accelerateDecelerate())
                .build()

You need to put your code that updates the UI in the UI thread:

runOnUiThread(new Runnable() {
@Override
public void run() {
    //put your code here   
    }
});

The problem is that I think you are using the application context in that syntax. In this kind of library, you have to use the context of the activity's context. like getActivity() in fragment and Mainactivity.this in the activity.
