android - Java 文件未找到异常 - /proc/mtprof/status：打开失败：

Question

谁能解释为什么会发生此错误？

我使用媒体播放器从资产文件夹播放一个音频文件，并在可绘制文件夹的 imageview 中显示一些图像。项目是在 android 4.0.3 api 中构建的。

在将 admobsdk 添加到 project 之前，这非常有效。现在我无法在 imageview 中看到图像。谁能给我解决方案？

代码

AssetFileDescriptor descriptor;
mediaPlayer = new MediaPlayer();
mediaPlayer.setOnCompletionListener(this);
descriptor = getAssets().openFd("test.mp3" );
mediaPlayer.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength() );
descriptor.close();
mediaPlayer.prepare();
mediaPlayer.start();
buttonPlay.setBackgroundDrawable(getResources().getDrawable(R.drawable.pause_button));
buttonPlay.setTag(getResources().getString(R.string.pause));
