it looks related to obfuscation, have you tried to disable `minifiedEnabled` ? — shizhen, Nov 28 '18 at 06:17
this is multidexing issue, have you enabled multidex in your app? — karan, Nov 28 '18 at 06:17
have you added dependency `compile 'com.android.support:multidex:1.0.0'` — karan, Nov 28 '18 at 06:23
have you tried remove google gms pulgin then sync and then add it again ? — Ali Ahmed, Nov 28 '18 at 06:23
also if you are extending from `Application` class extend it from `MultiDexApplication` — karan, Nov 28 '18 at 06:24
@KaranMer I do every things that related to multidex according to this https://stackoverflow.com/a/27284064/9868485 — code4rox, Nov 28 '18 at 06:25
if you have done everything, then try to clean and build or invalidate cache and restart — karan, Nov 28 '18 at 06:27
@KaranMer I have already clean ,build ,invalidate cache and restart , app run perfectly all other devices instead of android 9 . I got this error only on android 9 — code4rox, Nov 28 '18 at 06:31
@code4rox : they have deprecated support for Apache HTTP client starting from andorid pie, check change log for reference https://developer.android.com/about/versions/pie/android-9.0-changes-28#apache-p — karan, Nov 28 '18 at 07:09

Here is official docs

If you are using com.google.android.gms:play-services-maps:16.0.0 or below and your app is targeting API level 28 (Android 9.0) or above, you must include the following declaration within the element of AndroidManifest.xml.

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

This is handled for you if you are using com.google.android.gms:play-services-maps:16.1.0 and is not necessary if your app is targeting a lower API level.

and also add this tag in Menifest.xml

<application
.....
.....
android:usesCleartextTraffic="true">

if you are using send and received request to server like (Volley , retrofit and Http request)

Also try this one (optional)

convert the project to AndroidX make sure backup of project first.
