mediaRecorder java.langRuntimeException停止失败 - 录制音频

Question

我试图录制音频，而且需要高质量。

这个代码在很多设备上运行良好，但是在某些设备上，例如galaxy s4 mini，moto G，甚至是Galaxy s4和HTC one mini，它都行不通。

这是我的录音方法

public class RecordingHandler {

    private static MediaRecorder recorder;

    static void beginRecording(String output) throws Exception {

        ditchMediaRecorder();
        File outFile = new File(output);
        if (outFile.exists())
            outFile.delete();
        recorder = new MediaRecorder();
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
        recorder.setAudioEncoder(MediaRecorder.getAudioSourceMax());
        recorder.setAudioEncodingBitRate(16);
        recorder.setAudioSamplingRate(44100);
        recorder.setOutputFile(output);
        recorder.prepare();
        recorder.start();
    }

    static void ditchMediaRecorder() {
        // if we have the recorder, release it
        if (recorder != null)
            recorder.release();
    }

    static void stopRecording() {
        if (recorder != null) {

            try {
                recorder.stop();
            } catch (RuntimeException stopException) {
                // handle cleanup here
                Log.d("Recording Handler", "Runtime Exception");
            }
        }
    }

}

我得到的错误
