How to make a bluetooth connection in android? -


i want connect device: http://www.rhydolabz.com/index.php?main_page=product_info&products_id=479

i tried using bluetoothchat class samples. did not work. says unable connect device.

then tried use following code within try catch

        // create socket connection: need server's uuid number method m = d.getclass().getmethod("createrfcommsockettoservicerecord", new class[] { int.class }); socket = (bluetoothsocket) m.invoke(d, 1); socket.connect(); log.d("wcam", ">>client connectted"); inputstream = socket.getinputstream(); outputstream = socket.getoutputstream(); socket.close(); toast.maketext(this, "bluetooth connected", toast.length_long).show();

and following error

04-18 20:45:01.660: w/system.err(6780): java.lang.nosuchmethodexception: createrfcommsockettoservicerecord [int] 04-18 20:45:01.660: w/system.err(6780):     @ java.lang.class.getconstructorormethod(class.java:460) 04-18 20:45:01.660: w/system.err(6780):     @ java.lang.class.getmethod(class.java:915) 04-18 20:45:01.660: w/system.err(6780):     @ com.xpleria.wirelesscontroller.login.onstart(login.java:90) 04-18 20:45:01.660: w/system.err(6780):     @ android.app.instrumentation.callactivityonstart(instrumentation.java:1133) 04-18 20:45:01.670: w/system.err(6780):     @ android.app.activity.performstart(activity.java:4475) 04-18 20:45:01.670: w/system.err(6780):     @ android.app.activity.performrestart(activity.java:4526) 04-18 20:45:01.670: w/system.err(6780):     @ android.app.activity.performresume(activity.java:4531) 04-18 20:45:01.670: w/system.err(6780):     @ android.app.activitythread.performresumeactivity(activitythread.java:2434) 04-18 20:45:01.670: w/system.err(6780):     @ android.app.activitythread.handleresumeactivity(activitythread.java:2472) 04-18 20:45:01.670: w/system.err(6780):     @ android.app.activitythread$h.handlemessage(activitythread.java:1173) 04-18 20:45:01.670: w/system.err(6780):     @ android.os.handler.dispatchmessage(handler.java:99) 04-18 20:45:01.680: w/system.err(6780):     @ android.os.looper.loop(looper.java:137) 04-18 20:45:01.680: w/system.err(6780):     @ android.app.activitythread.main(activitythread.java:4424) 04-18 20:45:01.680: w/system.err(6780):     @ java.lang.reflect.method.invokenative(native method) 04-18 20:45:01.680: w/system.err(6780):     @ java.lang.reflect.method.invoke(method.java:511) 04-18 20:45:01.680: w/system.err(6780):     @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:817) 04-18 20:45:01.680: w/system.err(6780):     @ com.android.internal.os.zygoteinit.main(zygoteinit.java:584) 04-18 20:45:01.680: w/system.err(6780):     @ dalvik.system.nativestart.main(native method)

any way how can modify code..?

couple of notes:

a) it's not obvious class of variable d. assume it's bluetoothdevice

b) if assumption 1) correct, can't find method createrfcommsockettoservicerecord(int), because actualy method createrfcommsockettoservicerecord(uuid).

c) it's not clear me, why use reflection method. can call on object directly.

d) there piece documentation says: "hint: if connecting bluetooth serial board try using well-known spp uuid 00001101-0000-1000-8000-00805f9b34fb. if connecting android peer please generate own unique uuid.". think applicable you.

update 1

regarding using directly.

you code should 

 d.createrfcommsockettoservicerecord(someuuid);

since createrfcommsockettoservicerecord method of bluetoothdevice.

regarding uuid.take @ this:

android: obtaining uuid of bluetooth device

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
