I really need help, I'm bashing my head against a brick wall. this just doesn't work. it wont send int across at all. Ive followed a guide. Ive done my best it just wont send, does anyone know a better way? should I make a global? would that work better but I'm not sure how id do it as I seem limited on what code I can use in the canvas watchface service.

all I want Is to send an int from one activity to another. Using a watchface service not a companion. I want to learn. so if you do answer don't just paste the code straight out, unless its easier to just paste the code and I can follow it, and decipher it.

thank you for any help .

<-- old While I understand how to make in java a simple app that saves the users selection of a radio button and then puts it over to a separate activity to, say, change the color of text, i have hit a point where im struggling to do so in android wear.

The reason being i cant Implement the following.

@overide
public void onCreate(Bundle savedInstanceState){
     super.onCreate(savedInstanceState);
      Radiogroup = (RadioGroup)findViewById(R.id.myyrad);
      Radiogroup.setOnCheckedChangedListener(new OnCheckedChangedListener()) { ....

the following cant be implemented on the wallpaper service?

is there any alternative? or do i have to go the extremely confusing googleapiclient route? any help would be greatly appreciated thank you.

This was solved. Nothing wrong with the tutorial or my code. Studio was looking for a different android play service. Changed it in the gradel
