How start a service (module2) from another activity (in module1) in android studio? -

i have project in android studio 2 modules: wear , mobile. in wear module have wearservice , in mobile module have handactivity. want start wearservice handactivity, pressing button. how can it? im trying use code, wasnt working.

package com.example.joe.activitytoactivity;  public class wearservice extends wearablelistenerservice { public wearservice() { }   @override public int onstartcommand(intent intent, int flags, int startid){     super.onstartcommand(intent, flags, startid);     return start_sticky; } 

}

and

package com.example.joe.activitytoactivity;  public class handactivity extends activity {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_hand); }   @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.menu_hand, menu);     return true; }  @override public boolean onoptionsitemselected(menuitem item) {     // handle action bar item clicks here. action bar     // automatically handle clicks on home/up button, long     // specify parent activity in androidmanifest.xml.     int id = item.getitemid();      //noinspection simplifiableifstatement     if (id == r.id.action_settings) {         return true;     }      return super.onoptionsitemselected(item); }  public void sendmessage(view view) {     intent intent = new intent(handactivity.this,com.example.joe.activitytoactivity.wearservice.class);     startactivity(intent); } 

}

where problem? android studio part wrong: intent(handactivity.this,com.example.joe.activitytoactivity.wearservice.class

edit:in intent, ide says: cannot resolve symbol "wearservice"

obs: sorry may english.

instead of

intent intent = new intent(handactivity.this,com.example.ewelton.activitytoactivity.wearservice.class)

try

intent intent = new intent(this,wearservice.class); 

also, new activity needs declared in androidmanifest such:

<activity     android:name = "com.example.joe.activitytoactivity.wearservice"     android:label = "optionalname" </activity>
