The latest release of the Crashlytics Gradle plugin is a major
version (v3.0.0) and modernizes the SDK by dropping support for lower versions
of Gradle and the Android Gradle plugin. Additionally, the changes in this
release resolve issues with AGP v8.1+ and improve support for native apps and
customized builds.
Minimum requirements
Crashlytics Gradle plugin v3 has the following minimum requirements:
The uploadCrashlyticsSymbolFilesBasicRelease task will only upload the
symbols in MY/NATIVE/LIBS,
but uploadCrashlyticsSymbolFilesFeatureXRelease will upload symbols in
both MY/NATIVE/LIBS
and MY/FEATURE_X/LIBS.
Replaced the closure field symbolGenerator with two new top level fields:
symbolGeneratorType, a String of either "breakpad" (default) or
"csym".
breakpadBinary, a File of a local dump_syms binary override.
