MediaPlayer готовит Failed Error (1, -17) при использовании записанного файла .3gp
Я пытаюсь записать с AudioRecorder, затем я пытаюсь воспроизвести то же самое с Media Player, но его предоставление mediaplayer.prepare () не удалось подготовить. Может ли кто-нибудь сказать мне, что могло бы привести причину. Ниже приведен код, который я использую
public void onClick(View v) {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
if(case_value==0)
recorder.setOutputFile(deviceMIC_path);
else if(case_value==1)
recorder.setOutputFile(deviceMIC_Handset_path);
else if(case_value==2)
recorder.setOutputFile(headsetMIC_path);
recorder.setOnErrorListener(errorListener);
recorder.setOnInfoListener(infoListener);
try {
recorder.prepare();
recorder.start();
if (ENABLE_LOGS)
Log.e(LOG_TAG, resources
.getString(R.string.record_started));
Toast.makeText(context,
resources.getString(R.string.record_started),
Toast.LENGTH_LONG).show();
recording = true;
} catch (IllegalStateException e) {
Log.e("","ILLEAGAL EXCEPTION...");e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
Log.e("","IO EXCEPTION...");
}
catch(Exception e){
e.printStackTrace();
Log.e("","UNKNOWN EXCEPTION...");
}
}
});
stopButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (recording) {
if (ENABLE_LOGS)
Log.e(LOG_TAG, "Record is going to be stoped...");
recorder.stop();
if (ENABLE_LOGS)
Log.e(LOG_TAG, "Record STOPPED....");
Toast
.makeText(context, "Record STOPPED",
Toast.LENGTH_LONG).show();
recorder.release();
recorder=null;
}
}
});
playButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MediaPlayer mediaplayer = new MediaPlayer();
try {
if(case_value==0)
mediaplayer.setDataSource(deviceMIC_path);
else if(case_value==1)
mediaplayer.setDataSource(deviceMIC_Handset_path);
else if(case_value==2)
mediaplayer.setDataSource(headsetMIC_path);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
mediaplayer.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
catch(Exception e){
e.printStackTrace();
}
// mAudioManager.setSpeakerphoneOn(false);
if (ENABLE_LOGS)
Log.e(LOG_TAG, "CASE VALUE : " + case_value);
if (case_value == 0) {
if (MainActivity.headsetState == 0) {
if (!mediaplayer.isPlaying()) {
mediaplayer.start();
if (ENABLE_LOGS)
Log.e(LOG_TAG, "PLAY started...");
Toast.makeText(context, "PLAY started...",
Toast.LENGTH_LONG).show();
} else {
mediaplayer.stop();
}
