What

Engage users with a Snackbar from the design lib to e.g. rate or translate the app.

How

Get the dependency via JitPack:

or from JCenter ( might be behind JitPack ) like this:

compile "org.ligi:snackengage:$version"

Just add this where you want ( e.g. in the onCreate method of your entry activity )

SnackEngage.from(this).withSnack(new DefaultRateSnack()).build().engageWhenAppropriate();

This would than show this snack after some opportunities and never again when once clicked on Rate ( which takes you to Play store or F-Droid - anything that accepts the generated market:// link )

Other snacks that are possible:

or create your own snack - e.g. to make a survey.

combine them as you wish and add your own conditions:

SnackEngage.from(view)

.withSnack(new DefaultRateSnack())

.withSnack(new GooglePlayOpenBetaTestSnack()

 .withConditions(new NeverAgainWhenClickedOnce(),

  new AfterNumberOfOpportunities(42)))

.withSnack(new TranslateSnack("https://www.transifex.com/projects/p/snackengage")

 .withConditions(new IsOneOfTheseLocales(Locale.CANADA),

 new NeverAgainWhenClickedOnce(),

 new AfterNumberOfOpportunities(10)))

 .build()

.engageWhenAppropriate();

Why

This lib came to exist because I wanted something like discreet-app-rate - but using a Snackbar from the new material design support lib which was emerging at Google I/O 2015. After thinking about it I wanted to make it more broad - not only for rating - also engaging users by pointing them to beta-testing and translation.

Details

The DefaultRateSnack just configures a RateSnack with default conditions:

public class DefaultRateSnack extends RateSnack {

public DefaultRateSnack() {

withConditions(new NeverAgainWhenClickedOnce(), new AfterNumberOfOpportunities(5));

  
}
  
}

you can easily roll your own analog to this default one:

public class AfterNumberOfOpportunities implements SnackCondition {

private final int number;

public  AfterNumberOfOpportunities(final int number) {

this.number = number;
  
}

@Override
  public boolean isAppropriate(final SnackContext context, final Snack snack) {

return context.getStats().getOpportunitiesSinceLastSnack() > number;
  
}
 
}

you can also have a custom snack with an image added:

.withSnack(new OpenURLSnack("market://details?id=org.ligi.survivalmanual", "survival") {

 @NonNull
@Override
protected Snackbar createSnackBar(final SnackContext snackContext) {

  Snackbar snackbar = super.createSnackBar(snackContext);

  final TextView textView = (TextView) snackbar.getView().findViewById(android.support.design.R.id.snackbar_text);

  textView.setCompoundDrawablesWithIntrinsicBounds(R.mipmap.survival, 0, 0, 0);

  textView.setCompoundDrawablePadding(getResources().getDimensionPixelOffset(R.dimen.rhythm));

  return snackbar;

}
 
}
.overrideTitleText("Other App by ligi:\nFree Offline Survival Guide")  .overrideActionText("Get It!")

Hints

If you use a FloatingActionButton inside a CoordinatorLayout from the design-lib and they are not coordinated - pass a view into snackengage from which the Snackbar can find the CoordinatorLayout - e.g. the fab:

SnackEngage.from(fab)..;

So the movements between Snackbar and FAB are coordinated
