Touch input and focus issue in android kitkat

archanaharish — Wed, 20 Sep 2017 07:51:44 GMT

Hi ,

We are porting android kitkat to SAMA5D3 development board which is of size 480*272 (pixel), only partial touch input is happening like drop down and Setting page when I keep giving inputs randomly and nothing else. But touch works well with Evaluation Kit which is of size 800*600 (pixel length).

The cause of touch issue is, it is taking requested height as 19 instead of 480 in WindowManagerService. Please refer the below log.

I/WindowManagerService( 1418): relayoutWindow win.mRequestedWidth272
I/WindowManagerService( 1418): relayoutWindow win.mRequestedHeight19
I/WindowManagerService( 1418): AOSP:::updateFocusedWindowLocked
I/WindowManagerService( 1418): AOSP:::computeFocusedWindowLocked

Any help will be appreciated.
