我有简单的标准代码，它记录视频如下
public class TtActivity extends Activity {
/** Called when the activity is first created. */
File videoFile;
Uri fileUri;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.newconferencehomelayout);
videoFile = new File(Environment.getExternalStorageDirectory(),"test.mp4");
if(!videoFile.exists()){
try {
videoFile.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(videoFile));
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, 1);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 1){
if(resultCode == RESULT_OK){
Toast.makeText(TtActivity.this, "File saved at "+videoFile.getPath(), Toast.LENGTH_SHORT).show();
}
else if (resultCode == RESULT_CANCELED) {
Toast.makeText(TtActivity.this, "Recording cancelled..", Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(TtActivity.this, "Capturing failed..", Toast.LENGTH_SHORT).show();
}
}
}
在清单中我有

所以我的问题是在录制完成后创建文件但视频文件的大小为 0 字节...因此无法播放它..所以请帮我解决这个问题..我正在我的 htc 愿望手机上测试它.
