startActivityForResult 运行 intent.ACTION_VIDEO_CAPTURE 导致“停止失败”错误

Question

我创建了一个自定义列表界面。我正在使用数组适配器来管理列表视图单元格的按钮点击。我的一个按钮会打开一个对话框，其中提供了录制视频的选项。

在我的适配器getView 方法中，我有按钮的点击监听器。当我选择视频录制按钮时。摄像机意图正确打开，我可以录制一些视频，但是当我单击停止时，应用程序冻结并且摄像机屏幕刷新（这次除外，我无法单击录制）。我正在使用 Genymotion 作为模拟器。我可以按ESC退出冻结屏幕。

我的 Activity 中的 onActivityResult 方法会在按下 ESC 后被调用。

这是我在 MainActivityListAdapter 中调用 startActivityForResult 的方法：

video.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            File mediaFile = new
                    File(Environment.getExternalStorageDirectory().getAbsolutePath()
                    + "/myvideo.mp4");

            Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
            fileUri = Uri.fromFile(mediaFile);
            Globals shared = Globals.getInstance();
            shared.setValue(qid);
            shared.setFile_path(fileUri);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
            ((Activity) context).startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);
            dialog.dismiss();
        } // end method onClick
    }); // end setOnClickListener

我正在为我的文件路径和其他我需要的参数使用全局变量，因为onActivityResult 中的 data.getData() 返回一个空指针异常。

这是我的onActivityResult 在我的MainActivity：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Globals shared = Globals.getInstance();
    String qid = shared.getValue();
    switch (requestCode) {
        case CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE:
            Uri selectedVideo = shared.getFile_path();
            Toast.makeText(this, "Video Path:\n" +
                    selectedVideo, Toast.LENGTH_LONG).show();
            //rest of the code hasn't been filled in yet, 
            //but this shouldn't be affecting my problem...I think
            break;
    }
}

我的 logcat 中出现以下错误：

Answer 1

这是 Genymotion 模拟器的问题。测试时，这个问题在我的平板电脑上消失了。
