Update examples to match new build system #10
Description
The new build system (the gradle stuff) is actually relatively nice (although it took me a whole day to figure out all of the details) and removes the need for the android tool.
I don't have time to update the examples right now and would also like to reduce some of the ridiculous boilerplate before that. I'll just document the most interesting ingredients here for later/others. I'll have more time in a couple of weeks.
It may be possible to shorten this a bit, but this is the conventional setup. The root (build) folder should contain these files for packing a .so into an apk with a native activity:
/build.gradle - top level build file (boilerplate)
/setting.gradle - this where the actual build file is includes (boilerplate)
/gradlew (boilerplate to make this work on independent of systems gradle version)
/gradle (boilerplate to make this work on independent of systems gradle version)
/app/build.gradle - actual build file
/app/src/main/AndroidManifest.xml
/app/src/main/jniLibs/armeabi-v7a/libexample.so - put the compiled go library here
/app/src/main/assets - put assets here
Running gradle(w) build will produce an apk.
