Question

我在Android中使用内置的相机应用程序使用这样的意图：

             final Button Capture=(Button)findViewById(sankalp.jain.sky.R.id.capture);

             Capture.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Uri fileUri; 
            final Intent intent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            Log.w("intent","for camera");//displayed
            fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
            Log.w("getoutput","getit");//displayed
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
            Log.w("hello","hello the 2nd step");//displayed

            startActivityForResult(intent,CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}

我已经实现了相关的getOutputMediafile（）方法，图像保存在/mnt/sdcard/Pictures/Samarth/chart.png中 SD卡是40MB，目前只有2个文件，总共大约100KB。

问题是相机可以完美地处理一些随机数量的快照，然后随机挂起然后给出一个ANR。它是完全随机的，重新启动模拟器不起作用，有时也可以。

这是logcat输出

logcat的：

Answer 1

我自己无法弄清楚原因，但由于某些问题，当我决定将模拟器升级到Google API15（来自API10）时，相机不再挂起。升级还纠正了一些奇怪的问题，如

Force portrait mode in camera

希望有人帮助。

相机没有响应
