I am testing Google Map on Google Pixel running the latest version of Android Pie.
Caused by java.lang.ClassNotFoundException
Didn't find class "org.apache.http.ProtocolVersion" on path: DexPathList[[zip file "/data/user_de/0/com.google.android.gms/app_chimera/m/0000000e/MapsDynamite.apk"],nativeLibraryDirectories=[/data/user_de/0/com.google.android.gms/app_chimera/m/0000000e/MapsDynamite.apk!/lib/arm64-v8a, /system/lib64]]
This error occurs on Android 9.0.
Add the below code in the <application> element of manifest
<uses-library
android:name="org.apache.http.legacy"
android:required="false" />
Refer to Specify requirement for Apache HTTP Legacy library docs.
Google map is not property supported android 9+. Use the following code in your manifest file. it will work.
<uses-library
android:name="org.apache.http.legacy"
android:required="false" />
Thanks to @Anubhav Gupta, you can also update in build.gradle:
implementation "com.google.android.gms:play-services-base:16.1.0"
But this can brake a compatibility with Android 4, see App is having trouble with Google Play Services. Please try again.
