android-wificonnect

An android library to effortlessly connect to available WiFi networks

Check the demo app for this library here.

Make sure the app has location permission and the location services are enabled for the features to work.

Supported Features

Upcoming

• APIs that enables connection to any network (Open/WEP/WPA etc). There should be APIs that accept password in case network needs authentication.

Version 0.1.2

• Added WifiConnectionManager#abort() method. This should be called when your app wants to stop scanning or connecting to WiFi.
• The WiFi is enabled if it was disabled already. This happens if the broadcast that is received is initialStickyBroadcast, so if Wifi is disabled again by the user explicitly, abort() is called. This will remove all the listeners and the callbacks would no longer be received.

Version 0.1.0

• Initiate a scan for networks explicitly. If WiFi is turned off, it's turned on automatically and an attempt is made to connect to network.
• Scenarios specific to Android L (API Level 21-22) and Android Marshmallow (API Level 23) are handled. In case a user wants to connect to a network that doesn't provide internet connectivity (Captive Portal), WifiConnectionManager.setBindingEnabled(true) can be called that would ensure that the app uses the network (to which the device would connect to when WifiConnectionManager#connectToAvailableSSID(String SSID, WifiConnectionManager.ConnectionStateChangedListener listener) is called) to route traffic irrespective of whether it provides internet connectivity.
• WifiConnectionManager#connectToAvailableSSID(List<String> SSIDs, WifiConnectionManager.ConnectionStateChangedListener listener) accepts a list of SSIDs and can connect to an available network with strongest singal that has an SSID among SSIDs.
• Provide methods like WifiConnectionManager#checkBoundNetworkConnectivity() that enabled verifying and switching to using WiFi network to which app is bound currently for sending network traffic for whole device. It makes it as active network if network connectivity is available in case now Captive Portal login has been performed, otherwise it switches from using currently bound network.
• User can listen to AdvancedConnectionState that provides callback at different logical points in the process of connecting to a network.
• User receives a callback once either the connection has been successfully established ConnectionStateListener#onConnectionEstablished() or an error occurs ConnectionStateListener#onConnectionError().

Limitations as of Now

• As of now user can only connect to an Open Network (that doesn't need any authentication) using connectToAvailableSSID()

Including into project

Make your project-level build.gradle has jcenter() under repositories block. Your build.gradle should look like:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
    }
}

Gradle: compile 'com.intentfilter:android-wificonnect:0.1.2'

Add as android-wificonnect as dependency inside app module level build.gradle under dependencies block. Your app level build.gradle should look like:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.intentfilter:android-wificonnect:0.1.2'
}

Note:

1. Marshmallow dynamic permissions must be handled for the library to work as WiFi scanning starting from Android M needs ACCESS_COARSE_LOCATION permission.
2. Location should be enabled to get WiFi scan results.
