Create Template Project

You can createOrGet a new Kotgo template project fast by using the following command. Just paste and execute it at a terminal prompt. Have fun!

python -c "$(curl -fsSL https://raw.githubusercontent.com/nekocode/kotgo/master/project_creator.py)"

Of course, you can also download the python script to your local disk to run it. It depends on the requests lib.

Component Library

You can only use the kotgo's component library. It provides many useful tools to help you to build a MVP project fast and simply. Just add the JitPack repository to your root build.gradle:

repositories {
    maven { url "https://jitpack.io" }
}

And then add the dependency to your sub build.gradle:

dependencies {
    compile 'com.github.nekocode:kotgo:<lastest-version>'
}

RxLifecycle & RxBus

You can bind the RxJava subscriptions into the lifecycle of the class that implements RxLifecycle.Impl (such as base activity, fragment and presenter). It can help you unsubscribe the Observable when the activity or fragment is destoried.

MeiziRepo.getMeizis(50, 1).safetySubscribe({
    view.refreshMeizis(it)
}, {
    // onError
})

And you can use RxBus to send events everywhere. And then subscribe them in the class that implements RxLifecycle.Impl

RxBus.send("Success")
RxBus.safetySubscribe(String::class.java, {
    showToast(it)
}, {
    // onError
})

Fragment Presenter

This library uses fragment to implement presenter.

class MeiziPresenter(): KtPresenter<Contract.View>(), Contract.Presenter {
    override fun onViewCreated(view: Contract.View?, savedInstanceState: Bundle?) {
        view?.showToast("View created.")
    }
}

Single Activity Multiple Fragments

You can build applications with only one single KtFragmentActivity. Then use fragment instead of activity to make pages. The KtFragmentActivity and KtPresenter provides some functions to help you manage the fragments in the stack. Such as:

push()
pushForResult()
popThis()
popAll()
popUntil()
popTop()
pop()
startActivityForResult()
