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

I guess, the easier way to solve this issue without having to reinstall the SDK is to create a file called optional.json in \platforms\android-23\optional\ directory with the following content:

[
  {
    "name": "org.apache.http.legacy",
    "jar": "org.apache.http.legacy.jar",
    "manifest": false
  }
]

It solved the problem for me.

EDIT: Information taken from @domoch's answer below on how to locate your SDK location

To Locate your Android SDK's Location

Go to Android Studio Settings -> Appearence & Behavior -> System Settings and look for Android SDK Location. In Windows, it usually would be pointing to C:\Users\\AppData\Local\Android\sdk.
