DeepLinkDispatch provides a declarative, annotation-based API to declare application deep links.
You can register an Activity
to handle specific deep links by annotating it with @DeepLink
and a URI.
DeepLinkDispatch will parse the URI and dispatch the deep link to the appropriate Activity
, along
with any parameters specified in the URI.
Here's an example where we register SampleActivity
to pull out an ID from a deep link like
example://example.com/deepLink/123
. We annotated with @DeepLink
and specify there will be a
parameter that we'll identify with id
.
@DeepLink("foo://example.com/deepLink/{id}")
public class MainActivity extends Activity {
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getIntent().getBooleanExtra(DeepLink.IS_DEEP_LINK, false)) {
Bundle parameters = getIntent().getExtras();
String idString = parameters.getString("id");
// Do something with the ID...
}
...
}
}
Sometimes you'll have an activity that should handle several kinds of deep links. You can use the
@DeepLinks
annotation to register multiple deep links on an activity:
@DeepLinks({"foo://example.com/deepLink/{id}", "foo://example.com/anotherDeepLink"})
public class MainActivity extends Activity {
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getIntent().getBooleanExtra(DeepLink.IS_DEEP_LINK, false)) {
Bundle parameters = getIntent().getExtras();
String idString = parameters.getString("id");
// Do something with the ID...
}
...
}
}
You can also annotate static methods that return an Intent
. DeepLinkDispatch
will call that
method to create that Intent
and use it when starting your activity via that registered deep link:
@DeepLink("foo://example.com/methodDeepLink/{param1}")
public static Intent intentForDeepLinkMethod(Context context) {
return new Intent(context, MainActivity.class).setAction(ACTION_DEEP_LINK_METHOD);
}
Query parameters are parsed and passed along automatically, and are retrievable like any
other parameter. For example, we could retrieve the query parameter passed along in the URI
example://example.com/deepLink?qp=123
:
@DeepLink("foo://example.com/deepLink")
public class MainActivity extends Activity {
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getIntent().getBooleanExtra(DeepLink.IS_DEEP_LINK, false)) {
Bundle parameters = getIntent().getExtras();
if (parameters != null && parameters.getString("qp") != null) {
String queryParameter = parameters.getString("qp");
// Do something with the query parameter...
}
}
}
}
You can optionally register callbacks to be called on any deep link success or failure.
DeepLinkActivity
will broadcast an intent with any success or failure when deep linking. The intent
will be populated with these extras:
DeepLinkActivity.EXTRA_URI
: The URI of the deep link.DeepLinkActivity.EXTRA_SUCCESSFUL
: Whether the deep link was fired successfully.DeepLinkActivity.EXTRA_ERROR_MESSAGE
: If there was an error, the appropriate error message.
You can register a receiver to receive this intent. An example of such a use is below:
public class DeepLinkReceiver extends BroadcastReceiver {
private static final String TAG = DeepLinkReceiver.class.getSimpleName();
@Override
public void onReceive(Context context, Intent intent) {
String deepLinkUri = intent.getStringExtra(DeepLinkActivity.EXTRA_URI);
if (intent.getBooleanExtra(DeepLinkActivity.EXTRA_SUCCESSFUL, false)) {
Log.i(TAG, "Success deep linking: " + deepLinkUri);
} else {
String errorMessage = intent.getStringExtra(DeepLinkActivity.EXTRA_ERROR_MESSAGE);
Log.e(TAG, "Error deep linking: " + deepLinkUri + " with error message +" + errorMessage);
}
}
}
Add to your project build.gradle
file:
buildscript {
dependencies {
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.7'
}
}
apply plugin: 'android-apt'
dependencies {
compile 'com.airbnb:deeplinkdispatch:1.3.0'
apt 'com.airbnb:deeplinkdispatch-processor:1.3.0'
}
Snapshots of the development version are available in Sonatype's snapshots
repository.
Register DeepLinkActivity
with the scheme you'd like in your AndroidManifest.xml
file (using
airbnb
as an example):
<activity
android:name="com.airbnb.deeplinkdispatch.DeepLinkActivity"
android:theme="@android:style/Theme.NoDisplay">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="airbnb" />
</intent-filter>
</activity>
-keep class com.airbnb.deeplinkdispatch.** { *; }
-keepclasseswithmembers class * {
@com.airbnb.deeplinkdispatch.DeepLink <methods>;
}
That's it. The library will generate the class DeepLinkActivity
during compilation.
Use adb to launch deep links.
This fires a standard deep link:
adb shell am start -W -a android.intent.action.VIEW -d "airbnb://example.com/deepLink" com.airbnb.deeplinkdispatch.sample
This fires a deep link associated with a method, and also passes along a parameter:
adb shell am start -W -a android.intent.action.VIEW -d "airbnb://methodDeepLink/abc123" com.airbnb.deeplinkdispatch.sample
