Android - HTC手机中的录音

Question

当我使用三星或任何其他Android手机时，我没有问题，但是当我想使用我的HTC One X +时，录音机崩溃并且无法启动。

这是logcat输出：

这是我的代码！ ：

public void StartRecording(){
        MediaRecorder recorder;
        recorder = new MediaRecorder();
        recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
        recorder.setOutputFormat(MediaRecorder.OutputFormat.AAC_ADTS);
        recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
        recorder.setOutputFile(Environments.getExternalStorageDirectory+"test"+".AAC");
        try {
            recorder.prepare();
        } catch (Exception e) {
            // TODO: handle exception
            Log.e("MSG", "Could not Prepare Recorder !");
        }
        recorder.start();
        Log.d("MSG", "Recording finaly started !!!!!");
    }

这是新的Logcat错误！ ：

Answer 1

您是否尝试设置其他音频编码器或输出格式？

recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

输出文件名可以通过其他方式设置，如JCasso所述：

file = FileUtil.getRecordingFile("aac").getAbsolutePath();
recorder.setOutputFile(file);

recorder.prepare();

Answer 2

recorder.setOutputFile(Environments.getExternalStorageDirectory+"test"+".AAC");

输出文件名出错了。根据错误日志，您没有将其命名为“test.AAC”。

  

+ 989203626397_10 | 18 | -18：37.AAC

不是有效的文件名。

编辑： 还要确保sdcard未安装到pc。
