Android Manifest Duplicate Permissions
In your App manifest file add the below merge rule.
<uses-permission-sdk-23
tools:node="removeAll" />
Make sure you already added the location permission.
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Just replace below line to your existing uses permission would solve the issues.
What this causes because you added duplicated permission in manifest but below line split the permission.
<uses-permission
android:name="android.permission.ACCESS_COARSE_LOCATION"
android:maxSdkVersion="22"/>
