our application uses multithreading. The behaviour varies across devices—some devices crashes every 4 to 5 hours, while others crash after 24 hours. The Elo 22in-I-Series-4 has only 4GB of RAM, but we need to resolve the issue specifically on this device since many customers are using it. We have already tested on other vendor devices Qbic (BXP-321), and the app works as expected on the Qbic devices. The key difference is that the Elo device runs on GMS (Google Mobile Services), while the Qbic device runs on non-GMS (AOSP).

The error message is related to the app is accessing a deleted or invalid JNI global reference. If a global reference is deleted (
DeleteGlobalRef) but later accessed again.Do you have enabled multithreading in your application?
We are encountering a crash issue on one of our Android devices.
How often does a crash occur?
If the app mistakenly overwrites memory where a global reference was stored, it can result in accessing a bad reference. Can you change the bigger RAM devices to make a test? Elo 22in-I-Series-4 only has 4G RAM.
