Why Warning:Unable to find optional library: org.apache.http.legacy occurs?

Question

My gradle file:

apply plugin: \'com.android.application\' 

android { 
  useLibrary \'org.apache.http.legacy\' 
  compileSdkVersion 23 
  buildToolsVersion \         


        

Answer 1

The error is that the optional.json file is not in the \platforms\android-23\optional\ folder.

I solved this by the following:

1. Go to the sdk manager
2. Select Android Sdk and updates are available in the Appropriate API level.
3. Just update it.
