A simple no Internet dialog and snackbar, which will automatically appear and disappear based on Internet connectivity status.

Previews

Usage

Dependency

Step 1. Add the JitPack repository to your build file

Add it to your root build.gradle at the end of repositories:

allprojects {
    repositories {
        // ...
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

dependencies {
    // Material Components for Android
    implementation 'com.google.android.material:material:1.1.0'

    implementation 'com.github.ImaginativeShohag:Oops-No-Internet:v1.1.5'
}

Note 0. Minimum SDK for this library is API 21 (Android 5.0 Lollipop).

Note 1. Your application have to use AndroidX to use this library.

Note 2. Your have to use *.MaterialComponents.* in you styles.

Finally

To use the NoInternetDialog and/or NoInternetSnackbar, use the builder and initialize it in onResume() and finally destroy it in onPause().

The NoInternetDialog and/or NoInternetSnackbar will then automatically appear when no active Internet connection found and disappear otherwise.

Customizable attributes with their default values are given in the following example.

// Kotlin
class MainActivity : AppCompatActivity() {

    // No Internet Dialog
    private var noInternetDialog: NoInternetDialog? = null

    // No Internet Snackbar
    private var noInternetSnackbar: NoInternetSnackbar? = null

    // ...

    override fun onResume() {
        super.onResume()

        // No Internet Dialog
        noInternetDialog = NoInternetDialog.Builder(this)
            .apply {
                connectionCallback = object : ConnectionCallback { // Optional
                    override fun hasActiveConnection(hasActiveConnection: Boolean) {
