warning XA4218: Unable to find //manifest/application/uses-library at path: C:\Program Files (x86)\Android\android-sdk\platforms\android-22\optional\org.apache.http.legacy.jar

Issue

This warning indicates your AndroidManifest.xml file specifies //application/uses-library, but the library was not found within the Android SDK directory.

Solution

  • Verify you defined the @android:name correctly and the file exists.
  • Raise the value of //uses-sdk/@android:targetSdkVersion in AndroidManifest.xml to a higher API level.
