My application records an audio clip and sends the clip to the server using Retrofit2 after recording is completed. The file was received on the server, but the file is broken, I mean that the broken one is that it cannot be played. I use the following URL (example url:) mydomain.co/audio/myaudio.mp4to play an audio clip that I tried with another sound file using postman, the sound file can be played successfully. In addition, even downloading an audio clip shot by android via Filezillaalso has the same broken file.
This is how I record audio:
private void startRecordingAudio() {
Log.d("audiorecording","recording sound");
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
recorder.setAudioEncodingBitRate(16);
recorder.setAudioSamplingRate(44100);
MediaFileHelper fileHelper = new MediaFileHelper();
audioOutputFile = fileHelper.getOutputAudioFile();
recorder.setOutputFile(audioOutputFile.getAbsolutePath());
try {
recorder.prepare();
recorder.start();
} catch (IllegalStateException | IOException e) {
e.printStackTrace();
}
}
Here is the path to the audio file:
/storage/emulated/0/DCIM/myapp/AUDIO_20171023143717.mp4
, , .
recorder.setOutputFormat(MediaRecorder.OutputFormat.THERE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THERE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_WB);
.mp3, .mp4 .3gpp, , , .
, , , Retrofit2:
private void sendAudioToServer( final String audioFilePath,final String api_key){
Log.d("AUDIO FILE PATH",audioFilePath);
File audioFile = new File(audioFilePath);
RequestBody audioBody = RequestBody.create(MediaType.parse("audio/*"), audioFilePath);
MultipartBody.Part aFile = MultipartBody.Part.createFormData("audio", audioFile.getName(), audioBody);
OkHttpClient httpClient = new OkHttpClient.Builder()
.addInterceptor(new Interceptor() {
@Override
public okhttp3.Response intercept(Chain chain) throws IOException {
okhttp3.Request.Builder ongoing = chain.request().newBuilder();
ongoing.addHeader("authorization", api_key);
return chain.proceed(ongoing.build());
}
})
.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(AppConfig.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(httpClient)
.build();
AudioInterface audioInterface = retrofit.create(AudioInterface.class);
Call<ResultObject> serverCom = audioInterface.sendAudioToServer(aFile);
serverCom.enqueue(new Callback<ResultObject>() {
@Override
public void onResponse(Call<ResultObject> call, retrofit2.Response<ResultObject> response) {
ResultObject result = response.body();
if(!TextUtils.isEmpty(result.getSuccess())){
Log.d("audio Result " , result.getSuccess());
}
}
@Override
public void onFailure(Call<ResultObject> call, Throwable t) {
Log.d("audio error",t.toString());
}
});
