Problems with Google Play in app purchase (Something went wrong on our end)

AccuBattery uses Google Play in app billing for purchases. If you have a problem with purchasing upgrades, please try the following troubleshooting guides:

Google: Fix payment issue on your account

Google: Problems with in-app purchases

Because billing issues on Google's side often result in a cryptic, unhelpful message like the following one, please take a bug report if you want assistance with billing issues (take the bug report right after you get the error message).

If you already have purchased the premium upgrade but cannot activate it, see our help article at AccuBattery: Problems with activation of pro version instead.
