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


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:
.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)))


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.


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;
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") {
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);
return snackbar;
}.overrideTitleText("Other App by ligi:nFree Offline Survival Guide")
.overrideActionText("Get It!")


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:
So the movements between Snackbar and FAB are coordinated
