gomobile的两个有用参数,bind 生成动态库,build 生成apk
生成android动态库
gomobile bind -target=android github.com/dearcode/candy/server/android生成文件candy.aar,先查看下大小:
du -sh candy.aar
13M candy.aar巨大,13MB,本来想压缩下,发现这aar本身就是压缩过的,生成后的文件大小本身与代码有关,我用的是项目中的代码,如果按官方的测试代码生成的文件只有2MB
file candy.aar
candy.aar: Zip archive data, at least v2.0 to extract
指定运行平台
gomobile默认会生成四个平台arm, arm64, 386, amd64,你也可以指定平台,例:
gomobile bind -target=android/arm github.com/dearcode/candy/server/android这样生成的文件就相当小了,,,
du -sh candy.aar
3.0M candy.aar
package与struct同名问题
目前gomobile版本,包名不能与类名相同,如相同,则先最生根据包名生成的类文件的会被覆盖:
gomobile bind -v -target=android github.com/dearcode/candy/server/android
github.com/dearcode/candy/server/android
write /tmp/gomobile-work-063666765/fakegopath/pkg/android_arm64/github.com/dearcode/candy/server/android.a
write /tmp/gomobile-work-063666765/gomobile_bind/go_candymain.go
write /tmp/gomobile-work-063666765/gomobile_bind/go_main.go

write /tmp/gomobile-work-063666765/android/src/main/java/go/error.java
write /tmp/gomobile-work-063666765/gomobile_bind/java_universe.c
write /tmp/gomobile-work-063666765/gomobile_bind/universe.h
write /tmp/gomobile-work-063666765/gomobile_bind/seq_android.go
write /tmp/gomobile-work-063666765/gomobile_bind/seq_android.c
write /tmp/gomobile-work-063666765/gomobile_bind/seq.h
write /tmp/gomobile-work-063666765/gomobile_bind/seq.go
write /tmp/gomobile-work-981501834/gomobile_bind/seq.go
具体源码在这里:
https://github.com/golang/mobile/blob/master/cmd/gomobile/bind.go#L255
在GenJava时会生成包名对应的类,但在GenClass的时候,分根据golang里的struct名生成新的类,此时如果有相同,则会被struct生成的类覆盖。
