[android-developers] GSM communications
Hi All, I'm migrating an old pocket pc app to android and I need to use the GSM protocol (not only the SMS service). On windows mobile, we used AT commands over the Serial Port to communicate with our remote hardware. How can I implement this communication with Android SDK or NDK? Thanks in advance Regards -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Need help with a Java issue
Hi Mariano,
First of all, did you leave out synchronization for simplicity in this
mail or is it not in place at all ?
(assuming you do access EntityManager from multiple threads).
Also, pls doublecheck that EntryManager.java:1529 is really at the
spot you indicated (cannot verify with complete sources).
Specifically i am unsure about databaseHelper. Its just accessed in
you example, so could be null.
At best give the full file so we can check.

Hey guys.
This is not an Android issue per-se, but I am puzzled about a Java issue and
want to pick your brains.
I recently got a couple of bug reports with a NPE that I don't understand
and can't reproduce myself. Here is an abbreviated representation of the
offending class. I tried to stay as close to the actual code as possible.
public class EntryManager {
private static EntryManager instance;
private MapDBQuery, Boolean isMarkAllReadPossibleCache;
private EntryManager(Context ctx) {
..
isMarkAllReadPossibleCache = new HashMapDBQuery, Boolean();
..
}
public static synchronized EntryManager getInstance(final Context context)
{
if (instance == null)
instance = new EntryManager(context.getApplicationContext());
return instance;
}
void fireModelUpdated(final String atomId) {
..
isMarkAllReadPossibleCache.clear();
..
}
public boolean isMarkAllReadPossible(final DBQuery dbq) {
if (!isMarkAllReadPossibleCache.containsKey(dbq))
isMarkAllReadPossibleCache.put(dbq,
databaseHelper.isMarkAllReadPossible(dbq));
return isMarkAllReadPossibleCache.get(dbq); !-- NPE is raised here
}
..
}
In the last line from above a NPE is thrown. So the instance variable
isMarkAllReadPossibleCache must be null, right? But I don't see where this
could happen. It's initialized in the constructor and never set to null
afterwards.
For completeness here is a stack trace:

Any ideas?

Re: [android-developers] Re: API call from browser
This is an open source list, so pls give people at least 48h to answer before pushing. Nevermind. To my knowledge cloud2device service has not been opened yet. Though there is a website where you can get a sneak peak of what the API will look like.

Re: [android-developers] Re: Froyo-Problem: Calendar access

not use the official gcalendar data api at [1] ?
Sure this accesses the web and not just phone services..

Well, I would prefer to use published Uris, but there are none to
access the calendar. And there is not even any other official way to
enter and read calendar data. That's a pity.
But maybe some Google Andorid Wizard reads my cry for help ;-) and can
tell me, what's now wrong with Froyo and
String[] projection = new String[] { _id, displayName };
Uri calendars = Uri.parse(content://calendar/calendars);
Cursor managedCursor = act.managedQuery(calendars,
projection,access_level300, null, null);
