title: VK SDK android "sdk_fingerprint is incorrect" error
body: <p>I'm using official VK SDK for Android and currently I am trying to authorize a user via official VK app from Google Play Market. I have no errors when authorizing with login web page that pops up and asks for user's credentials, but if the app is installed it will send an intent to launch auth window in the app and it gives me that error:</p>

  <p>I am initializing the SDK, tried to get the fingerprint both using the Android Studio terminal and VKSDK method. Both return the same, but it doesn't work. Package name is copied to the settings of my VK app, no main activity is provided because it is not needed.</p>
