I use branch.io for work with app link. AndroidManifest has intent-filter for Branch URI scheme:
<intent-filter>
<data android:scheme="***" android:host="open" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
Also AndroidManifest has intent-filter for App Links:
<intent-filter android:autoVerify="true">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="https" android:host="***.app.link" />
<data
android:host="***-alternate.app.link"
android:scheme="https"/>
<data
android:host="***.test-app.link"
android:scheme="https"/>
<data
android:host="***-alternate.test-app.link"
android:scheme="https"/>
LaunchMode for AppLinkActivity is singleTask. I init Branch in Application, in onCreate:
Branch.getAutoInstance(this);
After open AppLinkActivity I get instance and I init session:
Branch branch = Branch.getInstance(getApplicationContext());
branch.initSession((referringParams, error) -> {
LogFileUtil.writeLog("Finish init session");
if (error == null) {
//Кое что делаю
} else {
//Кое что делаю
}
}, this.getIntent().getData(), this);
When I open my app across AppLink referringParams isn't empty. And I can get required data. But when app is open and I click AppLink from other app, that referringParams is empty. I think the problem is init Branch. How I can fix it?
Solution - you need to make AppLinkActivity class main. This activity must have one more intent-filter:
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
