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");
}

}
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 @MobileRequiredIf 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.
