问题描述

我是新的Android开发，我有一个问题/问题。

I'm new in Android development and I have the next question/problem.

我的MediaRecorder类玩弄记录从麦克风只是音频。我下面的官方网站指示的步骤： http://developer.android .COM /参考/安卓/媒体/ MediaRecorder.html

I'm playing around with the MediaRecorder class to record just audio from the microphone. I'm following the steps indicated in the official site: http://developer.android.com/reference/android/media/MediaRecorder.html

所以，我有一个初始化和配置MediaRecorder对象，以开始录制的方法。在这里，你有code：

So I have a method that initializes and configure the MediaRecorder object in order to start recording. Here you have the code:


        this.mr = new MediaRecorder();
        this.mr.setAudioSource(MediaRecorder.AudioSource.MIC);
        this.mr.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
        this.mr.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
        this.mr.setOutputFile(this.path + this.fileName);
        try {
            this.mr.prepare();
        } catch (IllegalStateException e) {
            Log.d("Syso", e.toString());
            e.printStackTrace();
        } catch (IOException e) {
            Log.d("Syso", e.toString());
            e.printStackTrace();
        }

当我在模拟器执行此code，感谢logcat的，我可以看到，该方法setAudioSource（MediaRecorder.AudioSource.MIC）给出了一个错误（与标签audio_ipunt）时，它被称为：

When I execute this code in the simulator, thanks to logcat, I can see that the method setAudioSource(MediaRecorder.AudioSource.MIC) gives the next error (with the tag audio_ipunt) when it is called:


ERROR/audio_input(34): unsupported parameter: x-pvmf/media-input-node/cap-config-interface;valtype=key_specific_value
ERROR/audio_input(34): VerifyAndSetParameter failed

然后当方法prepare（）被调用时，我得到了再次另一个错误：

And then when the method prepare() is called, I get the another error again:


ERROR/PVOMXEncNode(34): PVMFOMXEncNode-Audio_AMRNB::DoPrepare(): Got Component OMX.PV.amrencnb handle

如果我开始记录bycalling方法的start（）...我得到很多消息说：

If I start to record bycalling the method start()... I get lots of messages saying:


AudioFlinger(34):RecordThread: buffer overflow

然后...后停止并释放，....我可以看到一个文件被创建，但它似乎并不认为这是很好recorderd。安韦，如果我尝试这在真实的设备，我可以没有任何问题记录，但我不能玩什么，我只是记录下来。

Then...after stop and release,.... I can see that a file has been created, but it doesn't seem that it been well recorderd. Anway, if i try this in a real device I can record with no problems, but I CAN'T play what I just recorded.

我客串，关键是在我之前提到的这些错误。我该如何解决这些问题？任何建议或帮助？

I gues that the key is in these errors that I've mentioned before. How can I fix them? Any suggestion or help??

在先进的感谢！
