Annotation triggered connectivity checking for Android

Flender

Annotation triggered connectivity checking for Android - powered by Java's Aspect Oriented Programming Framework, AspectJ

Aren't you tired of doing this all over your code?

if(connectivityUtil.isConnected(context))
{
    //do something
}
else
{
   Toast.makeText(context, "Internet unavailable", LENGTH_SHORT).show();
}

With Flender connectivity checking couldn't be easier. Just annoate your method with @InternetRequired and Flender does the rest. A toast will be shown if there's no internet available and the method won't execute.

@InternetRequired
public void doSomething()
{
    Log.v("Flender", "this plugin rocks");
}

Download

buildscript {
  repositories {
    mavenCentral()
  }

  dependencies {
    classpath 'com.github.jd-alexander:flender-plugin:1.0'
  }
}

apply plugin: 'com.android.application'
apply plugin: 'flender'

Usage

For connectivity checking to work Flender needs access to the current context so set it like this : Flender.init(this); preferably in your application class or base activity. Once that's done, annotate away!.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Flender.init(this);
        test();
    }

    @InternetRequired
    public void test()
    {
        Log.v("Flender","Only logs if internet is available");
    }
}

You can also check for WiFi and Mobile connectivity with these annotations

@WiFiRequired

@MobileRequired

If for some reason you don't want toast to be shown eg. using Flender in a service class then simply pass silent as a parameter to the respective annotation

@WiFiRequired("Silent")

@InternetRequired("Silent")

If you want to trigger custom actions based on the annotation being used you can use one of the listeners associated each annotation.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Flender.init(this);
        Flender.setInternetUnavailable(new InternetUnavailable() {
            @Override
            public void flenderEvent() {
                materialDialog.show();
            }
        });
        test();
    }

    @InternetRequired
    public void test()
    {
    }

Once these listeners are used toasts,won't be triggered.
