Answer 1

The SENDER_ID field should be the project ID from when you created your google api project. Read the beginning of this: http://developer.android.com/guide/google/gcm/gs.html#libs

TAG should also be a string -> ""tag Name"

Answer 2

I had same problem, after update SDK in my project. it helped for me: I just "add support library" in "Android tools". Hope this helps anyone else.

Answer 3

Make a folder libs in your project folder and put the gcm.jar in it. Then add it to your class path using add external jars in configure build path option.

Answer 4

You have to put gcm.jar file inside libs, then go to project Properties > Java Build Path > Libraries and add it to your path using Add External JARs..., after in Order and Export you check gcm.jar and press OK. That should work
