App crashes when running maps activity

My projects Map activity is not working
I just pasted the api key in place google_maps_api.xml and clicked run

Logcat:

~~The same problem here when using target SDK 28. Reverting to SDK 27 solved the problem.~~

Don't revert your target SDK.

Better use this solution https://stackoverflow.com/a/50944537/5710605

I've found another solution at Android Google maps java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/ProtocolVersion

Just add this in your manifest:

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

Update:

Starting from Google Maps SDK version 16.1.0 you can skip adding the solution above as the tag has been added to the AndroidManifest of the maps library.

https://developers.google.com/maps/documentation/android-sdk/releases#2019-02-06

Added the following declaration to the AndroidManifest.xml to support the Apache HTTP client on Android P and above. After updating to com.google.android.gms:play-services-maps:16.1.0 you can remove this line from your own AndroidManifest.xml. (Issue 117591497)

<uses-library android:name="org.apache.http.legacy" android:required="false"/>
