Once approved, a “Direct Deals” section should be visible under your app in the Publisher Portal. Use the “Add Section” button if not visible.

Integrating Network Ads and Direct Deals

Firstly test the sample project attached with the plugin. Install the  App.apk  found in the SampleAppAndroid -> android folder and confirm Leadbolt test ads are showing correctly on your device.

Once Sample app is confirmed working, you can start integrating the plugin into your app. Open the lua file in any text editor and add the following lines of code in there. This code uses the Auto recaching option to fetch a new Ad automatically – no additional coding required.

You will need to replace "YOUR_APP_API_KEY"   with the specific api key for your app (include the double quotes). This is available in the settings menu for your app, under the option “Get App API Key”. To get Direct Deal Ads in your App, click on “Direct Deals” link in the Publisher Portal and click on the Apply button. If your app includes audio or background audio, please ensure you pause audio during ad display.

Once the lua code has been added, copy the Corona Plugin ( AppTracker.jar  and plugin.leadbolt.jar ) into the android -> libs folder of your project. (Screenshot can be attached here)

In your  AndroidManifest.xml  file, please ensure you have added the following permissions

Please ensure, the following activity is also declared in your AndroidManifest.xml file, just before the  </application>  tag.

Once the  AndroidManifest.xml  file is updated, open “Terminal” app on your Mac device and run the  build.sh  script (found in App’s android folder). This will create the APK file. Once APK file is created, you will need to sign and zipalign before installing the APK on to a device.

Before signing the APK, you need to create a valid keystore (if not already previously created). Create the keystore by running the following command:

Now sign the application with the newly created (or previously existing) keystore:

Now zipalign the signed APK file by running the following command:

The APK file is now ready to be installed on your device for testing. You can install the APK file by running the following command:


Using Rewarded Video

To run rewarded video in your App, you will need to apply and be approved. Click on “Rewarded Videos” link in the Publisher Portal to apply or contact your account manager.

When implementing “Rewarded Videos”, please make use of the following code in your App that displays a rewarded video and triggers a client side event listener when the user has watched the video. Check that a “Rewarded Video” section is visible under your app in the Publisher Portal. Use the “Add Section” button if not visible. Contact your account manager if you require a server side postback when the user has watched the video. If your app includes audio or background audio, please ensure you pause audio during ad display.

Please following code in your App. This code uses the Auto recaching option to fetch a new Ad automatically – no additional coding required.

You will need to replace   "YOUR_APP_API_KEY"  with the specific api key for your app (include the double quotes). This is available in the settings menu for your app, under the option “Get App API Key”.

Implementing Event Listeners

With Event Listeners, you can closely follow the ad states throughout your App. Leadbolt SDK will trigger events at all important stages of the Ad life-cycle. To implement event listener, follow the steps outlined below:

Add the following lines BEFORE calling startSession method:

Troubleshooting

  • Video and Interstitial Ads may not be available at all times in all countries. It is always best to test with your App in Test Mode in the Publisher Portal to ensure as Test Ads are generally always available.
  • You should check your Publisher Portal and ensure the relevant section is visible under your App. Use the “Add Section” button to add if not available.
  • You should check the SDK logs located in Logcat logs with the Tag “AppTracker”.
  • Always test the sample app provided to confirm any integration issues are SDK based.
