Hi Forum,

I've been trying to write an piece of code in Android mode in Processing to my HTC Desire's bluetooth to communicate with Arduino.  I am using Processing 1.5 / Android 2.1 (API Level 7)

I have tried using the Amarino library and also had a little play with the SweetBT library but when trying to compile I get the following error:

1.

Has anyone had any success with Amarino or SweetBT compiling to Android?  Can anyone help?

Hi,

Here is a sketch I have been using to do a geoLocation search using the twitter4j library.  It executes and prints the search URL but then doesn't print the tweets or count the tweets.size.  When you enter the URL into the browser there are results there but for some reason it doesn't display them.

The for() loop isn't running for some reason.  Can anyone point me in the direction as to why?

Any advice or help would be appreciated

Hi Forum,

I am running Processing 0194 on Mac OSX 10.5.8 and trying to get Android stuff up and running.
I installed the Android SDK and relevant components as per the instructions on the wiki. 
When I click run on Emulator or on device I get the Starting build message and the progress 
bar but nothing happens. I don't receive any error messages but I checked the console and 
this is the error message I get: 


Java requesting shared archive generation, version 1.5
Java shared archive: failed to locate updateSharingD server


Can anyone help me fix whatever problem I might have?

Thanks

Mat
