Huawei ADS reports an error when obtaining conversion tracking parameters: getInstallReferrer IOException: getInstallReferrer not found installreferrer

1. Problem description

The first thing we need to understand is: what are conversion tracking parameters?

This is a capability provided by Huawei's advertising services. Advertisers and App developers can obtain app conversion tracking parameters through the SDK provided by advertising services. Advertisers can analyze App promotion channels based on the conversion tracking parameters, which is convenient for advertisers.Clearly grasp the conversion performance analysis of each channel.Before obtaining conversion tracking parameters, make sure that the app must have integrated the ads-installreferrer SDK. For details, we can refer to the following documents:

developer.huawei.com/consumer/en/doc/development/HMSCore-Guides/identifier-service-obtaining-installreferrer-sdk-0000001050066937

For the ability to obtain conversion tracking parameters, Huawei ADS provides sample code and puts the code on GitHub. If you also need the case code, you can click the following link to download:

github.com/HMS-Core/hms-ads-demo-advertising-identifier/tree/master/InstallReferrer

After we understand the above, let's take a look at the specific problems:

Do not modify any code, run it directly on Huawei mobile phone, and select the sdk mode, then click "Conversion Tracking Parameter Example", after viewing the log, you will find the following error:

getInstallReferrer IOException: getInstallReferrer not found installreferrer

Since the problem has occurred, let's analyze and solve the error.

2. Problem analysis

You can see that the error is getInstallReferrer IOException. We should first go to the official documentation to see if we can find similar errors.

When we searched the documentation for this error, we saw the following code:

This exception may indeed occur in this callback, and then we continue to look for this callback and find its corresponding API documentation:

developer.huawei.com/consumer/en/doc/development/HMSCore-References/installreferrerstatelistener-0000001050064948

After comparison, you will find that this callback represents the callback when the service is established, and the error is thrown in the method getInstallReferrer(). Let's look for this method:

It can be seen that the function of this method is to obtain conversion tracking parameters, so here, we can clearly analyze what the problem is:

getInstallReferrer IOException: getInstallReferrer not found installreferrer is because no conversion tracking parameters were found.

3. Solutions

After running the Demo, it is not feasible to click the conversion tracking parameter example directly, and the above error will be thrown. We need to follow the steps below:

Select "Write Test Conversion Tracking Parameters" to fill in the conversion tracking parameter information:

Fill in the following information:

The package name is the package name of the current Demo, for example: com.huawei.pps.hms.test

The content of conversion tracking parameters can be added at will, for example: test

After the saving is successful, the conversion tracking parameters are obtained, as shown in the following figure:

OK, this problem can be solved here!
