I record some Audio file with my iOS application and I send it to an Android application through my web server.
The Android application successfully gets the file but when I use the MediaPlayer class to try and play it, it reports an error "Unable to to create media player" at the line mediaplayer.setDataSource(androidFilePath);
Just to mention, iOS devices can read the files sent with the app.
After some research I found that it may be an encoding issue. But I tried many recording settings provided here on SO but none has worked. Here is the code I use to record the audio file:
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryRecord error:nil];
NSMutableDictionary *recordSettings = [[NSMutableDictionary alloc] initWithCapacity:10];
[recordSettings NSNumber numberWithInt: kAudioFormatMPEG4AAC] forKey: AVFormatIDKey];
[recordSettings setObject:[NSNumber numberWithFloat:16000.0] forKey: AVSampleRateKey];
[recordSettings setObject:[NSNumber numberWithInt:1] forKey:AVNumberOfChannelsKey];
[recordSettings setObject:[NSNumber numberWithInt: AVAudioQualityMin] forKey: AVEncoderAudioQualityKey];
}
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath = paths[0];
self.audioURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf", basePath]];
NSError *error = nil;
self.audioRecorder = [[ AVAudioRecorder alloc] initWithURL:self.audioURL settings:recordSettings error:&error];
if ([self.audioRecorder recordForDuration:60] == YES){
[self.audioRecorder record];
}
Could you just tell me what change do I have to make so that Android devices can read those audio files?
