Hello rmeph,

without the line the error occurs, we cannot help much

Does it happen on startup or when you click sth. :?:

Did you create some Contacts before :?:

Hi plusminus,

as i run ur code for first few times, the appl. worked properly, but now the spot position is not repainted anymore. Coordinates and distance are updated, but not the spot position on map.
This happened first time as i tried to center the map according to the actual position. I changed the code and than, after compile and relaunch repainting stopped. So i reversed all changes but still there is no repainting!
I even set a complete new project in eclipse and reused ur code there-->same problem. I moved the appl. out of emulator, tried all what came to my mind with adb_server commands, deleted tmp data of emulator... nothing helped. The rest is well-oiled except repainting the map...
I m using WinXP SP2 with Eclipse IDE and latest JDK.
Any idea what i can do more to solve this?
And one more question: is there a efficient way to center map to a actual locationSpot, so the map moves and not my location?

Many thanks to a helpful code!

Hello navajo,

hard to say what is wrong with your code...

yes it's was happend on startup.........yes i created contacts before start application...........i debugger code but not problem in any line.....how to solved it? :cry:

Hello rmeph,

the error should also occur, when you do "live"-debugging...
Set a breakpoint to the first line of every function and go through step by step.
Without the line we cannot really help

Thank you for the work!
Can I please download this sample in a single zip file?

Hi plusminus!

I wrote a more powerful regular expression for geotags and moved it's compilation out from a do-while loop.

I expect geotag in following format:

Code: Select all: geo: +/-lat (-90 to 90), +/-lng (-180 to 180) [, +/-alt]

(based on http://tools.ietf.org/html/draft-mayrhofer-geo-uri-00 ) and regexp catches lat, lng and alt in groups 1, 5 and 13 respectively.

So no more # in geotag is required but it's ok if it'l stay there

I think that static function with a regexp parser will be more convinient, but anyway, here is my version of a refreshFriendsList ():

Hi shakespit,

oops :oops:

, of course pulling the pattern-compile out of the loop is very wise :!:

Thx for sharing your thoughts.

Hi, all

I have often experienced the alert of "Application not Responding".
The following warnings also appear in logcat.

W/ActivityManager( 465): Timeout of broadcast BroadcastRecord{4021f050 android.intent.action.LOCATION_CHANGED}
W/ActivityManager( 465): Receiver during timeout: BroadcastFilter{4020b368 android.app.IIntentReceiver$Stub$Proxy@4020b0d0}

I noticed that onReceiveIntent() is called in a chunky manner when such warnings/alert appear.
Does anyone have an idea why it occurs or how to fix it?

Thanks,

hama

Hello hama,

the following message means that there was no IntentReceiver that wanted to receive our custom "android.intent.action.LOCATION_CHANGED"-Action.

As FriendFinder-application is the only application aware of this intent, there is probably something wring with your code. With me it works all fine.

hi plusminus,

I am new to android.. i tried ur friendfinder and it is really good.. Can you tel me how to include search and direction options, so that i can get the complete path to reach my friend.. which is similar to cellidtolatlong tutorial..

It would be nice if you reply me as early as possible..

Thanks :lol:

plusminus · by **plusminus** » Fri Feb 15, 2008 11:11 am

Hello nisha,

there already is a :src: Driving-Directions Tutorial.
Which way made for m3-xxx SDK but should work for m5 (new SDK) with very slight changes.

plusminus

intellibitz · by **intellibitz** » Wed Feb 20, 2008 3:46 pm

The following permission needs to be added to AndroidManifest, if you are using the latest m5 release.

<uses-permission android:name="android.permission.ACCESS_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_GPS"/>

After running, I'm getting the same error as venkat. Probably the GPS not supports anything other than SF area. I remember reading something along those lines in the docs.

venkat wrote:Dear +/-,
while i am running your code i am getting my Contacts displaying like below,

zzzzzzzz (not set km)
xyzzzzzw(not set km)
abcdeww(not set km)

it's not handling click event at all. it's displaying nothing. can you tell me what is may be the error ???

Thanks in advance,
