Android lollipop error code -505 during installation app

Question

I have a nexus 9 with android lollipop but I get the error code -505 trying to install some apps from the Play Store.

These apps are:

• asphalt 8
• dungeon hunter 4
• six guns; and
• other gameloft game

Other apps works install fine but these games don't.

Can you tell me what this error code means? Can you suggest to me how I can fix it?

Answer 1

Let me guess - you your apps were made with adobe air?

It's a bug google introduced with lollipop. Its related to the SHA1 generation from some certificates.

See:

There is basically no solution except to wait for google to fix it or re-sign your app with a different key. But then you can't update it in the play store either.

If the app was installed on your device before the lollipop update, but is now gone, a workaround might be to uninstall the app using adb uninstall and then install it again.

update: As far as I know this is partially fixed in Android 5.0.1 and completely fixed in 5.0.2
