Flipper: Crashes on emulator

[Ghedeon]

🐛 Bug Report

Crashes on emulator. It's getting really difficult to justify Flipper, a debug tool shouldn't crash and block the development process.

To Reproduce

Build & Run

Environment

Emulator: Pixel 3 API 28, x86
Flipper: 0.30.1
Soloader: 0.8.0

Hello, i have the same problem.
Here are my dependencies:

debugImplementation 'com.facebook.flipper:flipper:0.30.1'
debugImplementation 'com.facebook.soloader:soloader:0.8.0'
debugImplementation 'com.facebook.flipper:flipper-network-plugin:0.30.1'

Tried on emulators with x86_64 and x86 versions.
Are there any chances for fixing this?

[mweststrate]

Is this for a React Native project? In that case the version of flipper should be kept lower, as described here: https://fbflipper.com/docs/getting-started.html#android (we are still working on a solution, but it is quite involved)

[Ghedeon]

It's a regular android project, not RN. One note, it works with the same x86 emulator but API 29, instead of 28.

[mweststrate]

For now it should be safe to diverge the versions of Flipper itself, and the application plugin (the api has been stable for a very long time). I think the build issue is on @passy's radar.

[gengjiawen]

Also @passy , Is there any way I can use higher flipper on React Native.

[passy]

@gengjiawen Not easily. We're working on it in https://github.com/facebook/react-native/issues/27565

[gengjiawen]

@gengjiawen Not easily. We're working on it in facebook/react-native#27565

Is it because react native use fbjni too. Duplicate code since react native include the source code ?

[gengjiawen]

Maybe remove fbjni source code from react native repo and use https://github.com/facebookincubator/fbjni as gradle dependency ? Is react native has some hack in it ?

[passy]

@gengjiawen Yes, that's exactly what I'm trying to do at the moment. :) Hopefully we'll get this landed soon.

We had a very similar problem in our Android builds. When inspecting the APK we noticed that the correct "so" libraries were not being included in the "lib/**" directories. It occured when we went from version "0.28.0" to "0.30.0" of the Flipper SDK.

We actually had to completely get rid of the library cache (ie. delete folders "~/.gradle/cache", "app/build" and rebuild everything). I thought deleting the entire cache would cause a really long build time but it was only a few minutes longer.

Not exactly sure why this worked but the problem has not reappeared.

go to android>app inside app delete build folder and rebuild the application again it worked for me very well.
Also you can look for gradlew clean
