Referral linking in Android like mCent application

Question

I have to implement the referral linking functionality in my application like mCent application. For that I have done the following lines of code.

My application Manifest file. In the <application >..... </application> , I have done some entries for it.

 <service android:name="com.google.android.gms.analytics.CampaignTrackingService" />
 <receiver
 android:name=".receivers.InstallReceiver"
 android:exported="true" >
 <intent-filter>
 <action android:name="com.android.vending.INSTALL_REFERRER" />
 </intent-filter>
 </receiver>

And My BrodcastRecevier class is as follow , please check it.

public class InstallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String rawReferrer = intent.getStringExtra("referrer");
        if (rawReferrer != null) {
            trackReferrerAttributes(rawReferrer, context);
        }
    }

    private void trackReferrerAttributes(String rawReferrer, Context context) {
        String referrer = "";

        try {
            referrer = URLDecoder.decode(rawReferrer, "UTF-8");
        } catch (UnsupportedEncodingException e) {
            return;
        }

        if (Strings.isNullOrEmpty(referrer)) {
            return;
        }

        Uri uri = Uri.parse('?' + referrer); // appends ? for Uri to pickup query string

        String memberCode;
        try {
            referringMember = uri.getQueryParameter("mcode");
        } catch (UnsupportedOperationException e) {
            return;
        }

        SharedPreferences.Editor editor = context.getSharedPreferences(
            BuildConfig.PACKAGE_NAME, Context.MODE_PRIVATE).edit();

        if (!Strings.isNullOrEmpty(memberCode)) {
            editor.putString(Constants.REFERRER_CODE, memberCode);
        }

        String referralMedium = uri.getQueryParameter("tc");
        if (!Strings.isNullOrEmpty(referralMedium)) {
            editor.putString("referral_medium", referralMedium);
        }

        editor.apply();
    }
}

But i am not receiving any referral from the above code... I have created the refferal link like this

Is there is any error in my referral link above OR friends , what am i doing wrong in my BroadcastRecevier class or in Manifest file

Answer 1

From this documentation I found that the action filter is (in manifest):

 <!-- Used for install referrer tracking-->
  <receiver android:name="YOUR_RECEIVER"
 android:exported="true">
  <intent-filter>
      <action android:name="com.android.vending.INSTALL_REFERRER" />
  </intent-filter>
 </receiver>

Also be sure that your Receiver is in that real package ".receivers.InstallReceiver", but package com.example.app.receivers;... is your package really com.example.app?

(I considered you to be using the Google Play Store app)... also, about your downvotes, this is likely to bad wording on your question, or that you are not showing effort about your question, finally, note that this is a "free to use community forum", and that people are random...

Finally, put a breakpoint in the Receiver, send a broadcast (using adb for instance), and test that you are really not getting the broadcast.
