applicationprovider's Introduction

ApplicationProvider

Retrieve the android application from anywhere

Useful to develop a standalone library

//from anywhere
val application = ApplicationProvider.application

Retrieve the current activity from anywhere

//from anywhere
val currentActivity : Activity? = ActivityProvider.currentActivity()

Or safety from a kotlin coroutine context :

launch {
    val currentActivity = ActivityProvider.activity() //cannot be null
    Log.d(TAG, "activity : $currentActivity")
}

Listen for current activity

launch {
    ActivityProvider.listenCurrentActivity().collect {
        Log.d(TAG, "activity : $currentActivity")
    }
}

Providers

If you need to execute a code automatically when the application starts, without adding it into your application's class code

Create a class that extends Provider

class StethoProvider : Provider() {
    override fun provide() {
        val application = ApplicationProvider.application //if you need the application context
        Stetho.initializeWithDefaults(application)
    }
}

Add it into your manifest

<provider
     android:name=".StethoProvider"
     android:authorities="${applicationId}.StethoInitializer" />

Initializers

You do not need to override the Application now

Before

class MyApplication : Application() {
    override fun onCreate(){
        Stetho.initializeWithDefaults(application)
    }
}

After

Using a provider (for libraries)

Note that you can include it directly on your library's aar

class StethoInitializer : ProviderInitializer() {
    override fun initialize(): (Application) -> Unit = {
        Stetho.initializeWithDefaults(application)
    }
}
<provider
     android:name=".timber.TimberInitializer"
     android:authorities="${applicationId}.StethoInitializer" />

Using an initializer

Another way using Initializer

val InitializeStetho by lazy {
    ApplicationProvider.listen { application ->
        Stetho.initializeWithDefaults(application)
    }
}

class MainActivity : AppCompatActivity() {

    init {
        InitializeStetho
    }

    override fun onCreate(savedInstanceState: Bundle?) {
    ...
    }
}

applicationprovider's Issues

Failed resolution of: Lcom/github/florent37/application/provider/ApplicationProviderKt

First of all, thank you for such a wonderful lib because We all know how much pain can cause by application context while developing a library module in Android.

I am developing a lib and I have used your lib to get application context. It is working perfectly but recently I have faced an issue when I added my lib to a dependency module. Following crash were throwing

Failed resolution of: Lcom/github/florent37/application/provider/ApplicationProviderKt

Let me elaborate little more further.

I have an app called FUN. It has 2 dependency module dep-one and dep-two Where both dependencies don't need any application context. Here I'm injecting my lib to dep-two
that's where the issue arises.

Any help would be appreciatable.
