Answer 1

I had the same problem. What helps to me is:
Install and set up the Google Play services SDK.
Add to AnroidManifest.xml in application section next line <uses-library android:name="org.apache.http.legacy" android:required="false"/>

Answer 2

In my case, it was due to the missing permission in AndroidManifest.xml
Adding the following permission resolved my issue.
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
If you are working on an emulator, make sure your emulator has Google Play Services.
