How To Use

1 - Add these permissions into your AndroidManifest.xml and request for them in Android 6.0+

<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WAKE_LOCK" />

2 - Open the recorder activity

String filePath = Environment.getExternalStorageDirectory() + "/recorded_audio.wav";
int color = getResources().getColor(R.color.colorPrimaryDark);
int requestCode = 0;
AndroidAudioRecorder.with(this)
    // Required
    .setFilePath(filePath)
    .setColor(color)
    .setRequestCode(requestCode)

    // Optional
    .setSource(AudioSource.MIC)
    .setChannel(AudioChannel.STEREO)
    .setSampleRate(AudioSampleRate.HZ_48000)
    .setAutoStart(true)
    .setKeepDisplayOn(true)

    // Start recording
    .record();

3 - Wait for result

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 0) {
        if (resultCode == RESULT_OK) {
            // Great! User has recorded and saved the audio file
        } else if (resultCode == RESULT_CANCELED) {
            // Oops! User has canceled the recording
        }
    }
}
