Very few supported devices on Google Play

I developed my app using cordova, uploaded it to Google Play but in the APK tab I can see that there are only 159 supported devices. The app is using network, GPS and storage. Any idea why it's not visible to more devices? This is the AndroidManifest file:

<?xml version='1.0' encoding='utf-8'?>
