Flash Builder 4.7 Release Build plays slow on Android

I am using FB 4.7 to build a mobile Flex app for Android (Nexus 10) which works fine when i use the debug apk in the development environment and on the Nexus but the release build plays at a slower framerate.


It feels like the GPU render setting in the xml is ignored. The framerate is very slow during a big animation but speeds up in smaller animations


If I decompile the release apk i can see the renderMode is set to GPU


The release build process is also ignoring all the folders and associated files in the bin-debug. The only files copied to the release temp folder are the swf (with smaller filesize) and the app xml. I have to manually copy all associated files with each build, which is quite annoying


Does anyone know how to fix the slow playback for release builds?


Or is there a way to rename the development apk so that it doesn't have the '-debug' suffix as this apk plays correctly

    hi ade_1,


    i have figured out excatly the same where i also have the nexus 10 tables. Do you had a chance to test it on another device?


    Do you have found a way to fix it?


    I use AIR SDK 3.8 with FB 4.7.


    The release version with runtime build-in is a lot of slower.






    When i debug the app (over USB) and then export a release version that is automatic installed on the device, i got the slow performance. BUT!! when i switch off the device, discounnect the USB calbe, start the release app, i got the full performance back.


    Can you try this and report if i´m right?
