Android Question MP4 won't play in webview


Licensed User
When I go to a website I can play the mp4-video. Within my app I go to the same website with webview and I can the the whole website, but the mp4-video won't play. In the Manifest I include SetApplicationAttribute(android:hardwareAccelerated, "true") and the video does play in a good way on tablets, but not on a telephone (androidversion 4.4.2). What can I do to let it play witin the webview?
