The file gets created and been saved inside the folder but when I click the button as a normal, error occurs. I have tried my level best to do but every time I get an error. getting an error that says
java.lang.RuntimeException: stop failed. at android.media.MediaRecorder.stop(Native Method)
Please help me so that I can complete my project.

This happens because you try to stop the MediaRecorder before it is prepared, a quick solution could be this:
try{
mediaRecorder.stop();
mediaRecorder.release();
}catch (Exception e){
}
Check the Documentation:
Note that a RuntimeException is intentionally thrown to the application, if no valid audio/video data has been received when stop() is called. This happens if stop() is called immediately after start(). The failure lets the application take action accordingly to clean up the output file (delete the output file, for instance), since the output file is not properly constructed when this happens.
