How to solve java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/util/ByteArrayBuffer

To solve the this problem just put the following code[<uses-library android:name=”org.apache.http.legacy” android:required=”false”/>] below tag on the manifiest tag. For eg:

<application
android:icon=”@drawable/icon”
……
android:theme=”@style/AppTheme.NoActionBar”>

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

This problem is caused by targeting target Android 9 and above versions of android. Thanks.
