Can not execute onClick
Thank you everyone for your help, it turns out that I had included a non existent directory in the file paths for the recording and play buttons.
Alright, here is the deal.
I used Google's example code for their AudioCapture class, here, for a project that I am doing for a class. I am creating a soundboard app where you should be able to record 4 different sounds, and play them back.
My issue surrounds my pClick and rClick functions, and I have reason to believe that it has to do with my Button tempButt line.
I appreciate you taking your time to read this, and possibly trying to help me with my issue. ☺
The error that I am receiving is this:

This is your exception not the one you mentioned:
Caused by: java.lang.IllegalStateException at android.media.MediaRecorder.start(Native Method) at com.example.oreoman.failuredude.AudioRecordTest.startRecording(AudioRecordTest.j ava:120)
Check if mRecorder.prepare(); throws an exception. If so fix the error.
Check if path in setOutputFile() point to existing files.
Check if you have this permission in manifest:
<uses-permission android:name="android.permission.RECORD_AUDIO" />

try below code
public void pClick(View v) {
//String theOne = v.getResources().getResourceEntryName(v.getId());
onPlay(mStartPlaying, theOne);
switch(v.getId()) {
case R.id.mPlayA:
Button tempButt = (Button)findViewById(R.id.mPlayA);
if(mStartRecording) tempButt.setText("Stop Playing");
else tempButt.setText("Start Playing");
break;
case R.id.mPlayB:
tempButt = (Button)findViewById(R.id.mPlayB);
if(mStartRecording) tempButt.setText("Stop Playing");
else tempButt.setText("Start Playing");
break;
case R.id.mPlayC:
tempButt = (Button)findViewById(R.id.mPlayC);
if(mStartRecording) tempButt.setText("Stop Playing");
else tempButt.setText("Start Playing");
break;
case R.id.mPlayD:
