I've create Audio recorder. When rotating my device the audio will be automatically saved. How can I avoid this ? I'm using Android 4.1.1 on device.
private MediaRecorder mRecorder = null;
private static final String LOG_TAG = "MediaAudioCapture";
ImageButton button_audio_button = (ImageButton) findViewById(R.id.audio_button);
button_audio_button.setOnClickListener(new OnClickListener() {
public void onClick(View record_button) {
ImageButton audio_button = (ImageButton) record_button;
if (!started_note_recording) {
if (!started_recording) {
startRecording();
audio_button.setImageResource(R.drawable.audio_red);
} else {
stopRecording();
audio_button.setImageResource(R.drawable.audio);
}
}
}
});
private void startRecording() {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mRecorder.setOutputFile(output.getAbsolutePath());
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
ImageButton button_audio_button = (ImageButton)findViewById(R.id.audio_button);
button_audio_button.setImageResource(R.drawable.audio);
}
}
});
try {
mRecorder.prepare();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}
mRecorder.start();
stopWatch.start();
}
That's because when you rotate, activity will be reload. You can fix the orientation to portrait or you have to change your logic to retain the state on rotation.

when I ran this code on my Samsung Galaxy s7 edge, as well as on the nexxus 7 emulator given by android studio the app crashes. I posted all of the code because im not sure exactly where its messing up. It crashes when I press the button. It as made to be a press and hold to record, and release to stop recording
Check if the issue is with permission recording audio.
Hi i am new for android and in my app i have to record audio using timer as like my below image, Using my below i can able record audio but how can do this scenario with help of timer please help me some
My code:-
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.record_button:
startRecording()
break;
case R.id.stop_button:
break;
}
}
private void startRecording() {
try {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mRecorder.prepare();
mRecorder.start();
} catch (Throwable t) {
t.printStackTrace();
}
}
private void stopRecording() {
mRecorder.stop();
mRecorder.release();
mRecorder = null;
}
Just start a timer in startRecording and stop it in stopRecording. See: https://stackoverflow.com/a/3734070/2324204
You can use a Chronometer which already exists in Android.
Note: Chronometer is a widget that extends TextView so replace your current TextView with the Chronometer.
Example with your code would be:
//....
Chronometer simpleChronometer = (Chronometer) findViewById(R.id.simpleChronometer);
//...
private void startRecording() {
try {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mRecorder.prepare();
mRecorder.start();
simpleChronometer.start(); // start a chronometer
//simpleChronometer.setFormat("Time Running - %s"); // set the format for a chronometer
} catch (Throwable t) {
t.printStackTrace();
}
}
private void stopRecording() {
mRecorder.stop();
mRecorder.release();
mRecorder = null;
simpleChronometer.stop();
}
In case you want to do things manually you can use the Stopwatch class.
Hi i am trying to make a video recorder android app> For some reason i need to get its audio, i have tried some libraries but nothing really extracted me the audio. So now my approach is that instead of using native libraries can i record video and audio separately? Main thread records video and another thread records audio. I am getting error when i call start() method of media recorder class inside thread and i get Start Failed -22. Following is my code.

Hi, I'm trying to record a video on android right now, when I run my code (the whole code above), the camera can't be initialized. I guess I have an error in the following part.
private boolean initCamera() {
try {
camera = Camera.open();
Camera.Parameters camParams = camera.getParameters();
camera.lock();
holder = videoView.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
catch(RuntimeException re) {
Log.v(TAG, "Could not initialize the Camera");
re.printStackTrace();
return false;
}
return true;
}
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); this line in this code gets multiple markers, saying
The method setType(int) from the type SurfaceHolder is deprecated
The field SURFACE_TYPE_PUSH_BUFFERS is deprecated
Does anyone know the reason why I'm getting this?
Try this code
first
setRecorder() ;
SurfaceView videoShootSurfaceView = (SurfaceView) findViewById(R.id.shootVideosurfaceView_VSD);
SurfaceHolder videoSurfaceHolder = videoShootSurfaceView.getHolder();
videoSurfaceHolder.addCallback(this);
videoSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
set the recorder type
public void setRecorder() {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP);
// recorder.setVideoSize(640, 480);
recorder.setVideoSize(320, 240);
// recorder.setVideoSize(480, 320);
// recorder.setVideoSize(176, 144);
recorder.setVideoFrameRate(15);
// recorder.setMaxDuration(3600000);
recorder.setMaxDuration(300000);
recorder.setOutputFile("/sdcard/videocapture_example.mp4");
}
override this methhod.
#Override
public void surfaceCreated(SurfaceHolder holder) {
camera = Camera.open();
recorder.setPreviewDisplay(holder.getSurface());
if (recorder != null) {
try {
recorder.prepare();
} catch (IllegalStateException e) {
Log.e("IllegalStateException", e.toString());
} catch (IOException e) {
Log.e("IOException", e.toString());
}
}
}
To start the recording
public void startRecording() {
setRecorder();
recorder.setPreviewDisplay(recoderTempHolder.getSurface());
if (recorder != null) {
try {
recorder.prepare();
recorder.start();
} catch (IllegalStateException e) {

} catch (IOException e) {
Log.e("IOException", e.toString());
}
}
}
To stop the recording
public void stopRecording() {
recorder.stop();
// recorder.reset();
recorder.release();
}
EDIT: When I click the record button a second time ( to stop recording ) it force closes the app. The specific code for that event:
else if(isrec) {
recorder.stop();
recorder.reset();
recorder.release();
recorder = null;
isrec = false;
Toast.makeText( getApplicationContext(),"No longer recording!",Toast.LENGTH_SHORT).show();
}
(Original question):
I'm having trouble trying to get an app to record sound on a button click. I've included the code... and here's what my Toasts tell me:
after setAudioSource
after setOutputFile
isrec is not true
trying...
caught IO Exception...
Any help is greatly appreciated.
private OnClickListener micListener = new OnClickListener() {
boolean isrec = false;
public void onClick(View v) {
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
Toast.makeText( getApplicationContext(),"after setAudioSource",Toast.LENGTH_SHORT).show();
recorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
File outputFile = null;
outputFile = getFileStreamPath("output.amr");
recorder.setOutputFile(outputFile.getAbsolutePath());
Toast.makeText( getApplicationContext(),"after setOutputFile",Toast.LENGTH_SHORT).show();
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
if(!isrec) {
Toast.makeText( getApplicationContext(),"isrec is not true",Toast.LENGTH_SHORT).show();
try {
Toast.makeText( getApplicationContext(),"trying...",Toast.LENGTH_SHORT).show();
recorder.prepare();
recorder.start();
isrec = true;
Toast.makeText( getApplicationContext(),"Recording!",Toast.LENGTH_SHORT).show();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText( getApplicationContext(),"caught IllegalState Exception...",Toast.LENGTH_SHORT).show();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText( getApplicationContext(),"caught IO Exception...",Toast.LENGTH_SHORT).show();
}
} else if(isrec) {
recorder.stop();
recorder.reset();
recorder.release();
recorder = null;
isrec = false;
Toast.makeText( getApplicationContext(),"No longer recording!",Toast.LENGTH_SHORT).show();
}
}
};
First of all, you should use a boolean for isrec instead of a string
That :
FileDescriptor fileName = null;
recorder.setOutputFile(fileName);
That means you want to record on a file which is null
If you create a file, and you pass it as a parameter of your recorder, it should work.
Edit : Sometimes the release doesn't work when you want to stop the recorder.
So, just keep stop() and reset()
Try the following code for the main activity :
public class AudioRecordTestActivity extends Activity
