Android: Java.lang.UnsatisfiedLinkError: library "libflutter.so" not found with `--local-engine` #114070

Closed dcharkes closed 2 years ago

dcharkes commented 2 years ago

When trying to run on Android with --local-engine on either device or emulator I get the error java.lang.UnsatisfiedLinkError couldn't find "libflutter.so".

Running without --local-engine works as expected on both device and emulator.

Maybe I'm holding it wrong. Are we supposed to do flutter run on Android with a --local-engine?

Possibly related issues:

--local-engine is supported on Android devices and emulators.

Make sure that the CPU target of the local engine build matches the device or emulator. Use the flutter/tools/gn --android-cpu flag to select a target architecture.

If it still isn't working, then try unzipping the APK archive built by flutter run and verifying that it includes the expected libflutter.so binary for an ABI that is compatible with the device.

Specifying either a single or all --android-cpus seems to have no effect on the build at all.

The variable "build_canvaskit" was set as a build argument
but never appeared in a declare_args() block in any buildfile.

To view all possible args, run "gn args --list <out_dir>"

The build continued as if that argument was unspecified.

Definitely the wrong libflutter.so, why though?

jason-simmons commented 2 years ago

Specifying multiple --android-cpu flags is not supported. The engine must be built separately for each target platform.

Also, some combinations are not going to work (e.g. doing a --runtime-mode=release build using AOT compilation with a target CPU like x86 where Dart does not support AOT)

dcharkes commented 2 years ago

Ah got it, I was building android_debug instead of android_debug_arm64, and passing android_debug instead of android_debug_arm64 as --local-engine.

Working setup:

Running `flutter/tools/gn --full-dart-sdk --no-prebuilt-dart-sdk --goma --android --android-cpu=arm --android-cpu=arm64` in /usr/local/google/home/dacoharkes/flt/engine/src/.
Running `ninja -C out/android_debug_arm64/ -j1000` in /usr/local/google/home/dacoharkes/flt/engine/src/.
flutter_app$ flutter run -d Nexus --local-engine=android_debug_arm64 --local-engine-src-path=/usr/local/google/home/dacoharkes/flt/engine/src

@jason-simmons should we error out on android_release, android_debug and android_debug_unopt without a CPU type? It seems that having gn and ninja not giving any error and selecting a CPU without telling us is kind of a footgun.

jason-simmons commented 2 years ago

If --android-cpu is not specified, then the flutter/tools/gn script defaults to 32-bit ARM (which is compatible with most Android devices)

dcharkes commented 2 years ago

I see, android_debug_arm doesn't exist.

I could have figured this out by reading the build files, but not so quickly. 🙃

Thanks for the help @jason-simmons !

Any real solution yet? I have the same issue in production on playstore console
