Android Question How to know the current frame of animated gif ?

[semar]

Dear all,
I'm using the B4XGifView view to show animated gif, and it works flawlessy.

However, I need to change the gif when the last frame is reached.

Sadly I don't see any method inside the B4XGifView that allow me to monitor the frames of the gif.

Any help would be very appreciated

Regards,
Sergio

For Each f As String In Array("giphy-downsized.gif", "loading_large.gif", "progress.gif")
    B4XGifView1.SetGif(File.DirAssets, f)
    Dim jo As JavaObject = B4XGifView1.GifDrawable
    jo.RunMethod("setLoopCount", Array(1))
    Dim duration As Int = jo.RunMethod("getDuration", Null)
    Sleep(duration)
Next

Many thanks Erel !

This JavaObject-thingy is really powerful. This is reflection, right ?

Is there any documentation out there, where I can look at, in order to find the available methods for an object, in this example, B4XGifView.Drawable ?
And how can I find out that I should use the B4XGifView.Drawable object, and not another one ?

Best regards
Sergio

Check the library source code. It is inside the b4xlib file (zip file).
