title: E/Unity: DllNotFoundException: Unable to load DLL 'FirebaseCppApp-7_1_0':[Solved]
body: <p>I built a unity game with firebase, then I exported it and integrated it to an existing Android app as an ARR file format.</p>
  <p>Everything was great and integrated, but the firebase in unity was not connected (it connected and worked as expected without integrating with the Android app).</p>
  <p>This error appears in the run console, without crashing just the firebase not connected
  <a href="https://i.stack.imgur.com/HJ4Ym.png" rel="nofollow noreferrer">Error in run console</a>
  please, I really need your help</p>
  <p>a big thanks in advance! :)</p>
  <hr />
  <p>I successfully solved the problem by simply search about the package 'FirebaseCppApp-7_1_0' in the launcher that unity exported(to launch the game as a standalone Android app ). Then I take the lib of that package and put them in the same folder in my existing app.</p>
  <p>That's up!</p>
