Solution 1:

Replace

 Uri.parse(Environment.getExternalStorageDirectory().getPath() + "/Video.mp4")

(which is invalid, since it lacks a scheme)

with:

Uri.fromFile(newFile(Environment.getExternalStorageDirectory(), "Video.mp4"))

SOLUTION@all Solution to access the external SD-card:

v.setVideoURI(Uri.parse("/storage/sdcard1/testvideo.mp4")); 

instead of

v.setVideoURI(Uri.parse(Environment.getExternalStorageDirectory().getPath() + "/testvideo.mp4")); 

REASON:

Environment.getExternalStorageDirectory().getPath() == "/storage/emulated/0"

Environment.getExternalStorageDirectory().getPath() delivers the path to an internal storage chip on my smartphone (HUAWEI P8) that is mounted like an SD-card but is not the external SD-card though.
