What did you expect to see?

build success

What did you see instead?

android and ios both failed

[no-bibi]

both java and xcode is installed

java -version

It may be related to go module feature.

The reverse binding procedure can be symplified as following:

1. find reverse import references in the source;
2. generate missing stub for reverse reference in temporary source folder (under the name of Java);
3. add the current temporary path to GOPATH(so the source could be referenced by Java/...);
4. generate go.mod if go module is enabled;
5. run go build.

However, when go module is enabled(step 4 is generated), step 3 is useless because gopath will be ignored so the generated sources can only be referred to gobind/Java/... instead of Java/....

[MagicalTux]

This means that the whole reverse binding feature is broken with go modules? Is there any workaround?

[MagicalTux]

I created a test.go file with:

package gomobiletest

import (
	"Java/java/util/jar/JarFile"
)

func ManifestName() string {
	return JarFile.MANIFEST_NAME
}

and go.mod:

module example.com/gomobiletest

go 1.21.3

require (
	golang.org/x/mobile v0.0.0-20231006135142-2b44d11868fe // indirect
	golang.org/x/mod v0.13.0 // indirect
	golang.org/x/sys v0.13.0 // indirect
	golang.org/x/tools v0.14.0 // indirect
)

Then ran gomobile bind -v -target android -androidapi 21 -work

Output:

We can see files such as Java/java/util/jar/JarFile/package.go are generated.

Generated go.mod:

module gobind

go 1.21.3

replace example.com/gomobiletest => /tmp/gomobiletest

require (
        example.com/gomobiletest v0.0.0-00010101000000-000000000000
        golang.org/x/mobile v0.0.0-20231006135142-2b44d11868fe
)

It seems this could be fixed easily enough by having extra replaces/requires added for each imported Java package with the appropriate path? Or just something for "Java" ?

Actually it looks like this isn't fixed yet since there's a new error (but that may be because I'm on master of gomobile).

That error happens with javapkg, but it doesn't happen with my own code which now works properly thanks to golang/mobile#94

gomobile bind -v -target android -androidapi 21 golang.org/x/mobile/bind/testdata/testpkg/javapkg

I was able build my project with:

go get github.com/MagicalTux/mobile@fix-62142
cd ~/go/pkg/mod
cd 'github.com/!magical!tux/mobile@v0.0.0-20231105125928-8f28ed50ef5f'
go build -o ~/dev/my-android-project/ ./cmd/gomobile

Is there a chance that this will be fixed and I won’t have to use this crutch?
Is it just me or is gomobile development abandoned?

[Jipok]

@MagicalTux i can build project with:
import "Java/java/lang/System"
but when i try:
import "Java/android/content/pm/ApplicationInfo"
i got:
