intent.setDataAndType（Uri.fromFile（file），video / *）;

startActivity（intent）;

I have 2gb of videos in memory card .mp4 format , i want to play video from memory card in android App.
I have trying some code.. but its working on only micro-max A2900 Device..


Intent intent = new Intent(Intent.ACTION_VIEW);
File sdCard = Environment.getExternalStorageDirectory();
File file = new File(sdCard, "/readvideo/faithclassvideo1.mp4");
intent.setDataAndType(Uri.fromFile(file), "video/*");
startActivity(intent);

推荐答案

试试这个：

Try this:

String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
String fileName =  "/readvideo/faithclassvideo1.mp4";
File f = new File(baseDir + File.separator + fileName);

别忘了：

Don't forget:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

祝你好运！
