I am trying to change the background of a button when the user press it in the emulator everything works fine but on a real device the app crash. here is my code: 

answerOne.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
               answerOne.setBackgroundResource(R.drawable.button_background_green);
                try {
                    Thread.sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

                ValidateAnswer(current5,Answers_six[0]);

Its happening due to the difference in the SDK of your emulator and real device.

You can check the sdk first and then set the Background like this -

     if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN){
         answerOne.setBackgroundDrawable(getResources().getDrawable(R.drawable.button_background_green));
       }
       else if(android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1)         {
      answerOne.setBackground(getResources().getDrawable(R.drawable.button_background_green));
     } else{
       answerOne.setBackground(ContextCompat.getDrawable(this, R.drawable.button_background_green));
   }
