For Tooleap to work with a signed apk (Release build), you need to obtain a valid Tooleap API Key.
The Tooleap API Key is unique per application package name (my.app.name). To generate an API key for your app you need to apply for our early access program.
If you are already a member of our early access program, follow this link to generate an API key for your app: API Keys Management.
After you have obtained the API Key, add the key value into your app’s AndroidManifest.xml file inside the application tag:
<!-- Tooleap Manifest Declarations....>
Note: You can still develop and test your Tooleap Apps without a Tooleap API key, if your app is signed using a standard Android debug key. Tooleap will fully work while your app is in debug mode, although you will see a notification reminding you to obtain a valid API Key.
Do not release an apk to the apps market without a valid Tooleap API Key, as Tooleap SDK will not function.
