I use the branch.io library to work with the app link. In the manifest, I specify the intent-filter for the 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>

For App Links, the manifest states:

 <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 listed as singleTask. I initialize Branch in the Application class, in the onCreate method:

 Branch.getAutoInstance(this);

When I open AppLinkActivity, I get an instance and initialize the 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);

Now to the problem. When I open the application via the AppLink parameter, the referringParams is not empty and I can pull the data I need from it. But when my application is open and I click on AppLink'y from another application, then the parameter referringParams becomes empty. It seems to me that the point is branch initialization. How can this be corrected?

    The solution is to make the AppLinkActivity class the main one. Those. this activation should have one more intent-filter:

     <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter>
