IBM Worklight - Push Notifications feature does not work in Android emulator

问题

I am trying to set up the sample project for Worklight push notification on Android. When I launch the app in the Android emulator only the first two buttons (isSubscribed and isSupported) are clickable. The other two buttons (Subscribe and Unsubscribe) remain disabled.

My steps are:

1. Import the project into Eclipse
2. Replace the SenderID and API Keys with the one obtains from GCM Console in application-descriptor.xml
3. Deploy the PushAdapter (included in the project)
4. Build and deploy
5. Launch the Android application in the emulator

What is missing?

回答1:

For Push Notifications to work in the Android Emulator, you need to make sure to install in the Android SDK Manager:

• The Google APIs add-on corresponding to the API Level you're using for your project (in Worklight it must be API Level 8 or above). The AVD you create should use this Google API

• The Google Cloud Messaging for Android Library (available in the Extras category)

Note: Push Notifications in the Android Emulator work only in an AVD running Android OS 4.x.x.

Next, you need to set-up GCM:
These steps are relevant whether you're using a device or emulator.

1. Create a Gmail email address
2. Go to GCM's web page: http://developer.android.com/google/gcm/gs.html
3. Click on "Google APIs Console page"
4. If you have never done step 3 above, you will be asked to create a project, this project will have an ID. This ID is the senderId value you place in application-descriptor.xml
5. Click on "Create new Server key..." / "Create new Android key"
6. The generated key is the API key value you place in application-descriptor.xml

Now you need to:

1. Build and deploy the application
2. Deploy the adapter
3. Run the app on a device or emulator
