question

Thank you for your reply and help! I guess the issue that I'm running into is that the CUSTOMER_TENDER intent is not reaching my activity.

Here is the activity definition.

<activity
    android:name="ApplyDiscountToOrder"
    android:label="@string/app_name"
    android:exported="true">
    <intent-filter>
        <action android:name="clover.intent.action.CUSTOMER_TENDER" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

I have also tried other intents. It seems that V1_PAY_BUILD_START works when I register it in code like this:

IntentFilter filter = new IntentFilter();
filter.addAction(Intents.ACTION_V1_PAY_BUILD_START);
registerReceiver(receiver, filter);

However, CUSTOMER_TENDER does not get triggered even when registered in code.

Adding a custom tender type using MODIFY_ORDER works perfectly. I would like to make it so that it doesn't require user input for the activity to be displayed...

Would you know why I'm not receiving the intents in my listener?

It seems that I needed to change the targetSdk to 25 in my build.gradle file. This seems to fix it. Also, my emulator does work for this either, I need to deploy to my device, and it works fine after the targetSdk versoion change...
