To implement deep linking and sharing together, need to implement this feature using branch.io

Add dependency :

 compile 'com.google.android.gms:play-services-appindexing:9.+' 

Add this code in the manifest file inside Launcher Activity

  <!-- Branch URI Scheme -->
        <intent-filter>
            <data android:scheme="androidexample" />
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
        </intent-filter>

        <!-- Branch App Links (optional) -->
        <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="example.app.link" />
            <data android:scheme="https" android:host="example-alternate.app.link" />
        </intent-filter>    

Add this code to your Launcher Activity, You will get your link and data in this method

@Override
public void onStart() {
    super.onStart();

    // Branch init
    Branch.getInstance().initSession(new Branch.BranchReferralInitListener() {
        @Override
        public void onInitFinished(JSONObject referringParams, BranchError error) {
            if (error == null) {
                Log.i("BRANCH SDK", referringParams.toString());
                // Retrieve deeplink keys from 'referringParams' and evaluate the values to determine where to route the user
                // Check '+clicked_branch_link' before deciding whether to use your Branch routing logic
            } else {
                Log.i("BRANCH SDK", error.getMessage());
            }
        }
    }, this.getIntent().getData(), this);
}    

Add this code in MyApplication class

 // Branch logging for debugging
    Branch.enableLogging();

 // Branch object initialization
    Branch.getAutoInstance(this);   

You can create deep link using this code

 LinkProperties lp = new LinkProperties()
.setChannel("facebook")
.setFeature("sharing")
.setCampaign("content 123 launch")
.setStage("new user")
.addControlParameter("$desktop_url", "http://example.com/home")
.addControlParameter("custom", "data")
.addControlParameter("custom_random", 
Long.toString(Calendar.getInstance().getTimeInMillis()));

buo.generateShortUrl(this, lp, new 
Branch.BranchLinkCreateListener() {
@Override
public void onLinkCreate(String url, BranchError error) {
    if (error == null) {
        Log.i("BRANCH SDK", "got my Branch link to share: " + url);
    }
}
});
