I just finished an android application using your interface, in the emulator works perfectly, when I export the apk and install it on several phones, it doesn't . I shared the app at a href="mailto:support@appery.io" rel="nofollow"support@appery.io/a.
I used the suggested minimum sdk 2.2 and the 4.2 at the preferred one, which is our case. Some of the android devices I tried to use it is the Samsung note 1 and note 3.
I gave permission to all modules of android os, I also tried to give just the necessary permissions.
Please have a look at the shared app. Any idea why it only works on the emulator and not on the devices?
Thank you for your time
