Zoom animation "jumps" in API 10 #477

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
In API 10 when the maps are zoomed in or out there is a visual "jump" to the 
tiles at the end. What appears to be happening is that the zoom level is 
changing before the scale operation is over (or vice-versa) and the wrong 
zoom-level is being shown for a brief moment.

This is likely a regression. See Issue 136 and Issue 230.

Regarding r1365 and Neil's comment for "Prepare for next release which will be 
4.0"..
Please don't forget this issue!

As those who want to use the latest osmdroid version have the unpleasant visual 
"jump" at API 10 (over 1/4 of active Android devices).

Best regards.

Hi,

Just a reminder, as it has been some time.
We cannot use osmdroid at API 10 devices, due to this issue.

We're stuck with 3.0.10 version, the latest working nicely at Gingerbread.

Are there any plans to fix zoom behavior?

Best regards, Emux

Try adding this to the bottom of MapController.onAnimationEnd():

        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
            mMapView.clearAnimation();
            mZoomInAnimationOld.reset();
            mZoomOutAnimationOld.reset();
        }

Let me know if that fixes it for you.

Thanks for your suggestion.
It seems to fix the zoom animation issue.

Best regards.

Another more minor issue at API 10, is that when we double tap the map, the 
zoom is performed at the view center and not at the tapped point.

Best regards.

Hi,

The fix at #5 works at API 10.
Can be committed at main source?

Best regards.

This issue was updated by revision r1399.

Add fix for API <= 10 and zoom animation.

This issues still appears on my Nexus 7 and Samsung Galaxy S2 Plus.

Whenever I zoom in, the Map "jumps" afterwards. The faster the zoom gesture, 
the larger the "jump". If I zoom slowly and smooth, the results are better, but 
still not perfect/as intended.
