hi Mitchell Can you give me exact idea why sencha touch does not support android 3 .I need to develop a crm app using sencha touch and android 3.2 device is the primary requirement ..can you give me some idea how can i do it ..or any thing that can help me .
Because its look like whatever i am coding not working well on android 3.2
Thank you

Android 3's browser has too many issues and would bloat the framework if the issues could be worked around at all.

Thanks for Early reply . Mitchell is there any way i can make change the default browser where the app opens through the sencha touch like may be my app will open in chrome browser automatically not the default browser of android ....

Or say me i cant develop for android 3 ......:(
