Slinger - deep linking library for Android

Slinger is a small Android library for handling custom Uri which uses regular expression to catch and route URLs which won?t be handled by normal intent-filter mechanism.

With slinger it?s possible to provide deep links for quite complicated URLs.

How do I use it?

Declare Activity in your manifest with your own IntentResolver that will handle links within particular domain.

ivity
droid:name="pl.allegro.android.slinger.SlingerActivity"
droid:excludeFromRecents="true"
droid:noHistory="true"
droid:theme="@style/android:Theme.NoDisplay">
eta-data
android:name="IntentResolver"
android:value="com.my.appp.ExampleIntentResolver"/>
<intent-filter android:label="@string/app_name">
  <action android:name="android.intent.action.VIEW"/>
  <category android:name="android.intent.category.DEFAULT"/>
  <category android:name="android.intent.category.BROWSABLE"/>
  <data
    android:host="example.com"
    android:pathPattern="/.*"
    android:scheme="http"/>
</intent-filter>

IntentResolver is a class that redirects URLs to concrete Activities based on regular expressions.

p
ic class ExampleIntentResolver extends IntentResolver {

ivate List<RedirectRule> rules;

blic ExampleIntentResolver(Activity activity) {
super(activity);
rules = asList(getRedirectRuleForAboutActivity(activity));


ivate RedirectRule getRedirectRuleForAboutActivity(Activity activity) {
return RedirectRule.builder()
                   .intent(new Intent(activity, MyConcreteActivityA.class))
                   .pattern("http://example.com/abc\\\\.html\\\\?query=a.*")
                   .build();


onNull @Override public Iterable<RedirectRule> getRules() {
return rules;

In case when no redirect rule is matched IntentResolver will fallback to default Intent - Uri with ACTION_VIEW.

Customizing

Matching Activities

In order to provide other mechanism than regular expression matching you can override resolveIntentToSling in IntentResolver

Enriching Slinged Intents with Referrer and input URL

Slinger enriches Intents with URL and referrer by default. This can be changed by overriding enrichIntent in IntentResolver

p
ic class ExampleIntentResolver extends IntentResolver {

onNull
verride
blic Intent resolveIntentToSling(@NonNull Uri originatingUri) {
// implement own intent resolving strategy here
return super.resolveIntentToSling(originatingUri);


verride
blic Intent enrichIntent(Activity parentActivity, Intent resolvedIntent, Uri originatingUri) {
// enrich resolved intent with custom data
return super.enrichIntent(parentActivity, resolvedIntent, originatingUri).putExtra("foo","bar");

Security considerations

Slinger does not sanitize input in any way. So providing security for application is your responsibility.
