处理如下：Java code try { mRecorder.prepare();//预期准备 Log.i(TAG, "recorder.prepare()" ); } catch (IllegalStateException e) { // TODO Auto-generated catch block Log.i(TAG,e.getMessage()); e.printStackTrace(); return false; } catch (IOException e) { // TODO Auto-generated catch block Log.i(TAG,e.getMessage()); e.printStackTrace(); return false; } try{ mRecorder.start(); //开始刻录 }catch (IllegalStateException e) { // TODO Auto-generated catch block Log.i(TAG,e.getMessage()); e.printStackTrace(); return false; }我对java不是很熟，不知道这样使用异常有没有问题？当一个进程再录音时，另一个进程启动时，我想得到mic的状态，类似于getStatuse（）之类的函数，请问大家有没有好的办法？谢谢！出错信息如下：04-26 02:23:59.241: E/MediaRecorder(3197): start failed: -104-26 02:23:59.251: D/AndroidRuntime(3197): Shutting down VM04-26 02:23:59.251: W/dalvikvm(3197): threadid=1: thread exiting with uncaught exception (group=0x4001d800)04-26 02:23:59.462: E/AndroidRuntime(3197): FATAL EXCEPTION: main04-26 02:23:59.462: E/AndroidRuntime(3197): java.lang.RuntimeException: Error receiving broadcast Intent { act=android.provider.Telephony.SMS_RECEIVED (has extras) } in com.TS.SnsReceiver@44ef9be004-26 02:23:59.462: E/AndroidRuntime(3197): at android.app.ActivityThread$PackageInfo$ReceiverDispatcher$Args.run(ActivityThread.java:905)04-26 02:23:59.462: E/AndroidRuntime(3197): at android.os.Handler.handleCallback(Handler.java:587)04-26 02:23:59.462: E/AndroidRuntime(3197): at android.os.Handler.dispatchMessage(Handler.java:92)04-26 02:23:59.462: E/AndroidRuntime(3197): at android.os.Looper.loop(Looper.java:123)04-26 02:23:59.462: E/AndroidRuntime(3197): at android.app.ActivityThread.main(ActivityThread.java:4627)04-26 02:23:59.462: E/AndroidRuntime(3197): at java.lang.reflect.Method.invokeNative(Native Method)04-26 02:23:59.462: E/AndroidRuntime(3197): at java.lang.reflect.Method.invoke(Method.java:521)04-26 02:23:59.462: E/AndroidRuntime(3197): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868)04-26 02:23:59.462: E/AndroidRuntime(3197): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626)04-26 02:23:59.462: E/AndroidRuntime(3197): at dalvik.system.NativeStart.main(Native Method)04-26 02:23:59.462: E/AndroidRuntime(3197): Caused by: java.lang.RuntimeException: start failed.04-26 02:23:59.462: E/AndroidRuntime(3197): at android.media.MediaRecorder.start(Native Method)04-26 02:23:59.462: E/AndroidRuntime(3197): at com.TS.RcdMediaCtrl.StartRecord(RcdMediaCtrl.java:70)04-26 02:23:59.462: E/AndroidRuntime(3197): at com.TS.SnsReceiver.onReceive(SnsReceiver.java:53)04-26 02:23:59.462: E/AndroidRuntime(3197): at android.app.ActivityThread$PackageInfo$ReceiverDispatcher$Args.run(ActivityThread.java:892)
