Hi Dan, I have one more question about：
if we compile binary bin file，in go file，we write：
func testDefaultFactory()(android.Module){
module := cc.DefaultsFactory()
android.AddLoadHook(module, testDefault)
return module
}
and if we compile shared lib，in go file ,we write:
func testDefaultFactory()(android.Module){
module := cc.LibrarySharedFactory()
android.AddLoadHook(module, testDefault)
return module
}
but if we compile an app, I want to change the prop that only belong to app
module, the binary module does not have. how do we write？ I tried to write
like this：
import (
//omit
"android/soong/java")
func testDefaultFactory()(android.Module){
module := app.AndroidAppFactory()
android.AddLoadHook(module, testDefault)
return module
}
there is a compile error：can't find import: "android/soong/java". would you
give me some help? thanks!
