-

hey have found plenty of tutorials people making databases on own computer trying connect 1 not local 

private class signupa extends asynctask<void, void, void> {      @override     protected void doinbackground(void... params) {         string url = "jbdc:mysql://mywbdb.cjymdxzuzy46.us-east-1.rds.amazonaws.com:3306/mysql";         string dbname = "profiles";         string driver = "com.mysql.jdbc.driver";         properties userinfo = new properties();         userinfo.put("user", "user");         userinfo.put("password", "pass");          try {              class.forname(driver);              connection conn = drivermanager.getconnection(url + dbname,                     userinfo);             charsequence text = "hello toast!";             toast tost = toast.maketext(getapplicationcontext(), text,                     toast.length_long);             tost.show();             conn.close();         } catch (exception e) {             e.printstacktrace();         }          return null;     } }

i have imported jdbc library , have tried using drivermanager.registerdriver still crashed.also changed url , username , password obvious reasons. please help, thanks!

you wouldn't expose mysql database internet - asking hacked. typically write web service , expose instead. android app make calls web service update database.
