Google Play - compatibility error with publishing a game made in Unity

how are you?

Well, I have problems playing the Google Play. The question is that my partner and I published the application on Google Play yesterday, but the application does not appear to be downloaded to any device, even if the minimum version is Android 2.2 (minimun SDK 8, target SDK 19). A message is always displayed stating that the device is incompatible. During development, we use Nexus 4 for tests, and everything works fine, but still can’t download the game on this phone to Google Play. The game has also been tested on the Galaxy S3, Nexus 5, XPeria U, and Moto G, all working fine, which is also impossible to download.

I changed everything in AndroidManifest.xml, as I see in different threads, but nothing has changed. There is the contents of my .xml

Please help, I do not know what to do.

Thank!
