机器人：媒体记录：启动失败：-38 [英] android: media recorder : start failed: -38

问题描述

简介：如何检查是否录音在后台在其他一些应用程序已经运行

Brief: How to check if voice recording is already running in background in some other app.

详细介绍：录音：如果录音是从本机应用程序的背景已经在运行。
现在我已经实现录音在我的应用程序的功能之一。

Detail: if voice recording is already running in background from native app: Voice recorder. Now I have implemented voice recording as one of feature in my application.

问题：当我在我的同时应用尝试记录，它提供了错误：

Problem: when i try recording in my app at the same time, it gives error :

  : E/MediaRecorder: start failed: -38
  : E/MyApp: [1162][com.sec.MyApp.multimedia.RecordMyVoice]java.lang.IllegalStateException
  : E/MyApp:    at android.media.MediaRecorder.start(Native Method)
  : E/MyApp:    at com.sec.MyApp.multimedia.RecordMyVoice.doInBackground(RecordMyVoice.java:100)

code。在第100行RecordMyVoice.java：

Code at 100th line in RecordMyVoice.java:

    mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mRecorder.setOutputFile(mFileName);
    mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    mRecorder.prepare();
    mRecorder.start(); //code at 100th line

但问题是，因为已经录音在后台运行。
因此，有没有什么办法阻止录音如果在其他应用程序的运行。

But problem is because already voice recording is running in background. Therefore is there any way to stop voice recording if its running in some other app.

任何投入将有很大的帮助。

Any input would be of great help.
