Can not play recorded audio file from android in iOS 5+

I am working on android app which also supports iOS. I want to record the audio & play it in Android as well as in iOS devices. I am recording audio in android using following settings

MediaRecorder audioRecorder = new MediaRecorder();
audioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
audioRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
audioRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
audioRecorder.setAudioSamplingRate(44100);
audioRecorder.setAudioChannels(1);
audioRecorder.setAudioEncodingBitRate(12800);
audioRecorder.setOutputFile(<recordedSoundFilePath>);
audioRecorder.prepare();
audioRecorder.start();

On iOS side , settings are as follows

//audioRecorder is object of  AVAudioRecorder 

NSMutableDictionary *recordSettings = [[NSMutableDictionary alloc] initWithCapacity:10];
    NSNumber *formatObject;
    formatObject = [NSNumber numberWithInt: kAudioFormatMPEG4AAC ];

    [recordSettings setObject:formatObject forKey: AVFormatIDKey];
    [recordSettings setObject:[NSNumber numberWithFloat:44100.0] forKey: AVSampleRateKey];
    [recordSettings setObject:[NSNumber numberWithInt:1] forKey:AVNumberOfChannelsKey];
    [recordSettings setObject:[NSNumber numberWithInt:12800] forKey:AVEncoderBitRateKey];
    [recordSettings setObject:[NSNumber numberWithInt:16] forKey:AVLinearPCMBitDepthKey];
    [recordSettings setObject:[NSNumber numberWithInt: AVAudioQualityHigh] forKey: AVEncoderAudioQualityKey];

    NSURL *soundFileURL = [NSURL fileURLWithPath:[self soundFilePath]];

    NSError *error = nil;
    audioRecorder = [[ AVAudioRecorder alloc] initWithURL:soundFileURL settings:recordSettings error:&error];

    if ([audioRecorder prepareToRecord] == YES){
        [audioRecorder record];
    }else {
        int errorCode = CFSwapInt32HostToBig ([error code]);
        NSLog(@"Error: %@ [%4.4s])" , [error localizedDescription], (char*)&errorCode);

    }
