“com.android.vending.INSTALL_REFERRER” fetching re

问题:

My server creates a link that redirects and passes parameters to google play store;

The sms I receive by my Server; https://goo.gl/{UNIQUE_ID}

when I click, I actually click on this this url below; http://www.mycompany.com/env=dev&token=123&id=456

The link above directs me to google play store to my app included parameters; https://play.google.com/store/apps/details?id=com.mycompany.app&referrer=123,456

Here is the question;(First time installation) When I install the app opened with the link above, I want to pass those "token", "id" parameters to my app in first time then I will skip login. These parameters creating by server because they are also unique to user.

I have setup the "com.android.vending.INSTALL_REFERRER" and I am able to receive parameters as expected but not consistent on every devices and could face with big delays.

 <receiver
        android:name=".GooglePlayReceiver"
        android:exported="true"
        android:permission="android.permission.INSTALL_PACKAGES">
        <intent-filter>
            <action android:name="com.android.vending.INSTALL_REFERRER" />
        </intent-filter>
    </receiver>

My GooglePlayReceiver Broadcastreceiver is;

public class GooglePlayReceiver extends BroadcastReceiver {

Context mContext;
String purchaseId = null;

public GooglePlayReceiver() {
}

@Override
public void onReceive(Context context, Intent intent) {
    try {
        mContext = context;
        Bundle extras = intent.getExtras();
        String verificationCode = null;
        String phoneNumber = null;
        if (extras != null) {
            String code = extras.getString("referrer");
            String[] strArr = code != null ? code.split(",") : new String[0];
            token = strArr[0];
            id = strArr[1];
        }
    } catch (Exception ex) {
    }
}}

This flow has big delays on some devices. For ex, Google Pixel 2 fetches the parameters immediately without delay, Samsung Galaxy S7 has 5-10 seconds delay.

How to solve this?

回答1:

Because the INSTALL_REFERRER is sent as a broadcast (documentation) it uses the publish subscribe model. There is no guarantee about timing.

Because of this you shouldn't design your app startup flow to rely on receiving the broadcast within a certain length of time. Android is open source, and changes made my different phone manufacturers will cause different promptness in the delivery of broadcasts.

I'd have a different design for your app:

• take the user always to the normal setup flow
• if the broadcast arrives later, allow the user to skip login
