Description

Please, provide the details below:

Via crashlytics we have been getting reports of crashes of the type
com.tns.NativeScriptException: Attempt to use cleared object reference id=48048(com.tns.NativeScriptException: Attempt to use cleared object reference id=48048 com.tns.Runtime.getJavaObjectByID(Runtime.java:893)

Did you verify this is a real problem by searching Stack Overflow and the other open issues in this repo?

Other closed bugs reference the same or similar issues (latest was closed for 3.0.0).

Please provide the following version numbers that your issue occurs with:
  • CLI: 3.2.1
  • Cross-platform modules: 3.2.0
  • Runtime(s): 3.2.0
  • Plugin(s):
    • nativescript-angular: 4.4.1
    • nativescript-fabric: 0.3.1
    • nativescript-pro-ui: 3.2.0
    • nativescript-google-maps-sdk: 2.3.3

Built using webpack (npm run ns-bundle --android --build-app --snapshot --clean --release)
Also using in app/package.json:

  "android": {
    "v8Flags": "--expose_gc",
    "markingMode": "none"
  }
Did the error happen while the app was being constructed? (buildtime error)

No

Did the error happen while the app was executing? (runtime error)

Yes, but I haven't reproduced it myself. Just numerous similar stack traces being sent via crashlytics/fabric.

e.g.

Research direction

Start with com.tns.Runtime.getJavaObjectByID(Runtime.java:893) and the supplied Crashlytics trace; compare the reported runtime versions and the Android markingMode configuration. Done requires a reproducible case and a verified fix for the cleared object reference crash, but the issue provides no reproduction steps.
