ReactiveConnectivity

ReactiveConnectivity - a library for Listen Connectivity Change on Android

API codebeat badge

ReactiveConnectivity is an Android Library to Listening NetworkConnectivity with RxJava Observables, It's written with Reactive Programming Approach. Library supports both new and legacy network monitoring.

Installation

  • Add the following to your project level build.gradle:
allprojects {
	repositories {
		maven { url "https://jitpack.io" }
	}
}
  • Add this to your app build.gradle:
dependencies {
	implementation 'com.github.amalhanaja:ReactiveConnectivity:1.0'
}

Permission

Add the ACCESS_NEWORK_STATE permission to AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Using RxJava2

  • Getting Observbale:
private val observable by lazy {
        ReactiveConnectivity.buildObserver(this)
                .subscribeOn(Schedulers.computation())
                .observeOn(AndroidSchedulers.mainThread())
    }
private var disposable: Disposable? = null  // Lazy Initialization
  • Initialize disposable on onStart() for Activity OR onResume() for Fragment method :
disposable = observable.subscribe({ onChange ->
            // TODO : DO SOMETHING ON NETWORK CHANGE
        }, { error ->
            // TODO : HANDLE ERROR HERE
        })
  • Dispose disposable on onStop() for Activity OR onPause() for Fragment method to avoid Memory Leaks :
disposable?.dispose()

Without RxJava2

  • Initialize Observer:
private val observer by lazy {
        ReactiveConnectivity(
                context = this,
                onError = { it.printStackTrace() },
                onChange = {
                    Toast.makeText(this, "MAIN ACTIVITY : ${it.name}", Toast.LENGTH_SHORT).show()
                }
        )
}
  • Subscribe observer on onStart() for Activity OR onResume() for Fragment method :
observer.subscribe()
  • Dispose observer on onStop() for Activity OR onPause() for Fragment method to avoid Memory Leaks :
disposable.dispose()
