I use the camera intent to capture video. Here is the problem: If I use this line of code, I can record video. But onActivityResult doesn't work.

    Intent intent = new Intent("android.media.action.VIDEO_CAMERA");

If I use this line of code, after press the recording button, the camera is freezed, I mean, the picture is still.

    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);

BTW, when I use $Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); to capture a picture, it works fine.

The java file is as follows:

    package com.camera.picture;
