SDK initialization fails on Android

[Kunal Rathod]

Hi There,

I'm using the Android Video Parallel sample in my Android application for LPR detection only.  The SDK works perfectly when the App is deployed to phone using debug mode but it crashes on SDK initialization in the signed released version of app installed via aab or apk.

Below are the logs from device when running a release version.  Please advise on how to resolve this issue.

As explained at https://www.doubango.org/pricing.html, the license depends on the device identifier. To make sure the device identifier won't change:
    1/ Always use the same signing keys (release or debug) to update your application. So, make sure not to loose your signing keys.
    2/ Do not change the application unique identifier.
    3/ We highly recommend not doing a factory reset on the device.

You’re using Singing keys S1 for the debug target and S2 for release. With S1!=S2. A token generated with S1 will be different than a token generated with S2 even if it’s the same device. Your logs show that the token you’re trying to use wasn’t activated using a runtime key from the running device. Based on your explanation I guess it’s the same device but you’re using different signing keys.

You have to generate a new token using your real Signing keys instead of letting Android Studio choose a random one (this is what it’ll do in Debug mode if you don’t set one).

On Android and iOS different singing keys means different developers. The OS will fortunately return different identifier on the same device for Developer D1 and D2 for security reasons. This is done this way by Google and Apple to prevent your device from being tracked across websites/apps.

Can I generate new token for the same device with a different signing key using the same slave key?  Or does this mean i've burnt one license key?

No, you cannot. The slave key can only be used once (https://www.doubango.org/SDKs/LicenseManager/docs/Jargon.html#slave-key). Your balance will be incremented if you generate another token on that device using another signing key.

Thanks for clarification.
