android4.2录制视频的关键代码

权限：

<manifest ... >
    <uses-feature android:name="android.hardware.camera" />
    ...
</manifest ... >

录像：

private void dispatchTakeVideoIntent() {
    Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    startActivityForResult(takeVideoIntent, ACTION_TAKE_VIDEO);
}

检查能否对视频进行处理：

public static boolean isIntentAvailable(Context context, String action) {
    final PackageManager packageManager = context.getPackageManager();
    final Intent intent = new Intent(action);
    List<ResolveInfo> list =
        packageManager.queryIntentActivities(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

播放视频：

private void handleCameraVideo(Intent intent) {
    mVideoUri = intent.getData();
    mVideoView.setVideoURI(mVideoUri);
}
