Types

The library provides NoInternetObserveComponent, a simple lifecycle-aware component. The purpose of the component is to provide an easy way to notify about the Internet connection connectivity change. It gives a simple interface to connect with any elements (Dialog, Snackbar, etc.) with ease. You can also use the BaseNoInternetDialog class to easily create custom no Internet dialog. The library currently provides two Dialogs and a Snackbar out of the box for no Internet notification.

No Internet Dialogs

  • NoInternetDialogPendulum (formerly just NoInternetDialog)
  • NoInternetDialogSignal

No Internet Snackbar

  • NoInternetSnackbarFire

Usage

Dependency

Add the followings to your project level build.gradle file.

android {

    // ...

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    // ...
    
    // Material Components for Android. Replace the version with the latest version of Material Components library.
    implementation 'com.google.android.material:material:1.2.1'

    implementation 'org.imaginativeworld.oopsnointernet:oopsnointernet:2.0.0'
}

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

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

Note 2. You have to use *.MaterialComponents.* in your styles.

Finally

Just initialize any of the NoInternetDialog* and/or NoInternetSnackbar* using the builder in onCreate(), that's all! :)

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 examples.

// Kotlin
class MainActivity : AppCompatActivity() {
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

Changelog

2.0.0

We move our library from jitpack.io to maven repository. So no need to add any repositories for using the library.

We changed the file structures and re-right the whole library. So you have to do a little refactoring to use version 2 of the library. Just follow the samples, you will get it. Or add an issue if there any problem to migrate.

The library now provides a simple lifecycle-aware component for observing the Internet connection changes. It can be used with any kind of custom elements.

We provide two out of the box dialogs and a snackbar implementation.

Notable other changes:

  • New: NoInternetObserveComponent lifecycle-aware component added.
  • New: Custom no Internet dialogs can be easily created using BaseNoInternetDialog class.
  • Changed: Previous NoInternetDialog now NoInternetDialogPendulum.
  • New: New NoInternetDialogSignal dialog added.
  • Removed: NoInternetSnackbar removed.
  • New: New NoInternetSnackbarFire added.
  • New: All the dialogs and snackbar are dark-mode ready.

1.1.4 & 1.1.5

  • NoInternetUtils functions are now documented.
  • Dialog width optimized for small screens.
