I recently launched an Android app which makes use of the Google Places autocomplete widget/API. As part of the configuration for this, I added the API key to my Android\'s
I believe the problem is with missing SHA-1 in your Google console, the place where You already activated api places. There should be place to add release SHA-1 (key). Then You will be able see Google Places on another devices.
To generate SHA-1 there is a gradle script in android studio. Click on Gradle bar which is placed on the right side of Android Studio. Select the name of Your app, open tasks>android>signingReport
. It will output all SHA-1 keys.
