ToneGenerator在Android 6.0中崩溃

问题描述

在我的应用程序中，我正在使用ToneGenerator播放简单的声音.通过使用6.0编译应用程序来测试我的应用程序时，由于ToneGenerator的init方法，我的应用程序随机崩溃.以下是例外.

In my application i am using ToneGenerator to play simple sound. When test my application by compiling the application with 6.0, my application randomy crashing due to ToneGenerator init method. Below is the exception.

 java.lang.RuntimeException: Init failed 
04-21 12:34:05.497  7166  7166 E MyApplication:     at android.media.ToneGenerator.native_setup(Native Method) 
04-21 12:34:05.497  7166  7166 E MyApplication:     at android.media.ToneGenerator.<init>(ToneGenerator.java:746)

我正在以下面的方式使用声音发生器.

I am using the tone generator in below way.

    public ToneGenerator toneGenerator;
    public void playSound() { 
       if (toneGenerator == null) {
          toneGenerator = new ToneGenerator(AudioManager.STREAM_NOTIFICATION, 100);
        }
       toneGenerator.startTone(ToneGenerator.TONE_CDMA_ANSWER, 200);
   }


   public void releaseToneGenerator() {
      if (toneGenerator != null) {
        toneGenerator.release();
      }
    }

有人遇到相同的问题吗?..以前我的应用程序在4.4上运行，因此我们没有观察到任何崩溃.在6.0中，应用程序崩溃了

Any one faced same issue?..Previously my application was running on 4.4 and in that we did not observe any crash. In in 6.0 application is crashing

推荐答案

通过使用处理程序解决了该问题.

Solved the issue by using handler.

private static void playTone(Context context, int mediaFileRawId) {
            Log.d(TAG, "playTone");
            try {
                if (toneGenerator == null) {
                    toneGenerator = new ToneGenerator(AudioManager.STREAM_NOTIFICATION, 100);
                }
                toneGenerator.startTone(mediaFileRawId, 200);
                Handler handler = new Handler(Looper.getMainLooper());
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        if (toneGenerator != null) {
                            Log.d(TAG, "ToneGenerator released");
                            toneGenerator.release();
                            toneGenerator = null;
                        }
                    }

                }, 200);
            } catch (Exception e) {
                Log.d(TAG, "Exception while playing sound:" + e);
            }
        }
