Android Question mediaplayer with webview android 4.4.2 not working

[joop]

I upgraded my samsung Tab 3 from 4.2.2 to kitkat 4.4.2 and now their is some strange behaviour.

When a button is pressed (html code) the mp3 file is loaded and played , but then a black screen
appears see the picture and stays on the screen

Kitkat 4.4.2 changed it's browser from webkit to chromium do I have to set something in
B4A or in HTML ?, I tried it with api 19 and 14 same result everything worked ok in 4.2.2 api 14.

Maybe someone has experienced this before and has a solution , or someone knows a
solution.?

HTML Code

<img src="file:///android_asset/merel640.jpg" alt="merel.jpg"> <br>
    <input type="text"  value="Merel" readonly>
  <input type="button" class="knop"  onClick="parent.location='file:///android_asset/merelvak11025.mp3' " >
  <br> <br>

B4A code

Sub WebView1_OverrideUrl(Url As String) As Boolean

Dim linkpart1,linkpart2,linkpart3,linkpart4  As String                            
               
'This SUB will grab the link the user clicked on and save it in URL
'bv 'file:///android_asset/sample.mp3'
' do something to show mp3 or pictures and utube
If Url.EndsWith("mp3") Then
  Url=Url.Replace("file:///android_asset/","") 'strip file:///android_asset
  Log(Url)
  Player.Load(File.DirAssets,Url)
  Player.Play
End If

Are you running it in rapid debug mode? If yes then see this thread: http://www.b4x.com/android/forum/th...g-rapid-”-b4a-3-50-version.38981/#post-230988

No Erel, I am using the release(obfuscated) mode , the behaviour is something like this
- press the button on webpage
- the black screen is displayed with a small icon and the mp3 file is played.
- the icon on the sceen is some kind of play icon you can
press on it then it becomes a pauze icon press again than play and so on
nothing else happens
- the return button from tab can be use to close this black screen with icon but the webpage is also gone.

Can you upload this project (File - Export as zip)?

 

[joop]

Yes i wil make a test project.

Erel here is the test project:

Ofcourse the HTMLFiles must be put in the Webviewkit\Files directory
Somehow these files are not in the Zip from B4a

 

[Erel]

1. Go to the Files tab and press Sync.
2. You need to return True from the OverrideUrl if you don't want the WebView to be redirected to this link.
3. Fix the warnings...

Yes thats it , strange that this mistake from me had no problems before 4.4.2 .
