When the Eclipse debugger stops due to an exception in my Android project, I can see the exception message in the variables window (e.g., "null pointer"), but how can I find out what Java code line my app was at when the exception occurred? I can see a stack trace in the LH window, but selecting any of them doesn't seem to reveal anything that relates to my code.

I have been searching for something like this for a while, finally made what I think is a decent solution on my own, and wanted to share it with the community. Comments would be appreciated, I think I may have some small bugs in the equality checking if the lines are parallel (I might need a <= where I have a < in case the last point is the overlap). Hopefully there are no glaring errors. Code...

View 2 Replies View RelatedMy current phone is a Behold, KRZR before that, and a Kyocera SOHO before that. I really like the Behold, it is by far the best phone I have used to date. But it is time for a change. I'm looking for a touchscreen phone with WiFi and Android and I don't want a data plan.
Requirements:
1) Touchscreen (no slider)
2) Android, preferably 2.2 or confirmed update in pipeline (or ability to root & update)
3) No Data Plan (I'm not willing to pay $30/month for something I won't often use)
4) WiFi
5) Fast processor, 800mhz or faster
6) Camera w/flash Possibilities:
1) Because I don't want data, I don't need 3g, so I could run an AT&T phone.
2) I am willing to root a phone, as long as the process is reasonably well explained in a how-to.
3) I am not looking for a new contract and am willing to pay outright for the phone.
4) If there is a phone that will work, I am willing to consider a phone not sold in the US, if I can get it on eBay or elsewhere. Remember, no data, no 3g, so that might open a few doors.
Can someone confirm or let me know if it's a problem with my setup where the 0.9 eclipse plugin will complain about not finding the SDK even if the workspace has no Android projects in it? I work on a few projects and many of them don't have Android apps involved, so it's a little annoying to get the popup on every single workspace.
View 7 Replies View RelatedI have searched the forum for GPS but find nothing so I am posting here, move if the wrong place. I have a VZ Droid and find that the phone service has to be turned on before the GPS will find any satellites. The fix will continue to hold if I switch to Air mode so the phone is not needed after initialization.
Google has been good enough to give us European maps but if a phone service is needed to initialize the GPS the location function etc will not work in Europe. I had planed on taking the Droid to Italy next year but it looks as if it will be useless. Any workaround or is my phone "broken"?
How do I LIST all the INTENTS supported by all the activities(all applications as well) in the Phone.
View 2 Replies View RelatedI posted earlier about finding apps that are now no longer on the Android Market. More so I wanted the Sickipedia app but it isn't showing anymore on the Market. Is there a place where I can go and find lists of apps that I can download as apk's and then install using Astro File Manager? Would also be great if someone actually had a link to the Sickipedia apk. Everything I have found in Google so far directs me to a link for the Android Market but the particular app doesn't exist there anymore.
View 2 Replies View RelatedGeocoder getFromLocationName is not returning anything if I'm searching for business places. Here are my finding so far:
CODE:..............
I've tested this on 1.6, 2.1 and 2.2 devices that has Google Maps.
I'm trying to find if there's a limitation explained somewhere on the SDK, but there is none except:
The amount of detail in a reverse geocoded location description may vary, for example one might contain the full street address of the closest building, while another might contain only a city name and postal code. The Geocoder class requires a backend service that is not included in the core android framework. The Geocoder query methods will return an empty list if there no backend service in the platform (http://developer.android.com/reference/android/location/Geocoder.html)
[update]
So after nights of research, I can't seems to make it work - Google simply wont give me the result. Some discussion on android-developers points a fact that getFromBusinessName was omitted when Google Navigation came out. So I'm starting to assume that Google is pulling back some of their geocoding service.
I can always create a webpage that use Google Geocoder API, but its limited to 2500 api call - and I dont think it will be legal (lol). So what are my alternatives here?
I am looking for a tutorial that explains the logic for fast, robust location finding.Basically I am sick of Google Maps finding my location so incredibly fast and accurately while my own application struggles to get a location.I would be fine with pseudo code responses and I will explain what I am doing so maybe I can be shown what I am doing wrong.
1. Get the locationManager object.
2. Do a 'get best provider' call.
3. Get a list of all available providers.
4. lm.requestLocationUpdates(bestProvider, 0, 0, this); hit the location provider as much as I can to get my first signal
5. Send a delayed message.If a location cannot be found in 10 seconds, switch to a different provider and try again with lm.requestLocationUpdates(nextProvider, 0, 0, this);
6. Repeat step 5 until I have a location.
7. Once a location is found determine if it is the most accurate provider.If it is not try again with the most accurate provider on an 8 second delay.If it is the most accurate provider then set lm.requestLocationUpdates(currentProvider, 30000, 0, this); to conserve battery
8. Make sure to lm.removeUpdates(this); before changing the requestLocationUpdates
Now it occurs to me that it may be possible to iterate through my list of providers and do requestLocationUpdates for all providers at once.Is this a viable option or can you only listen to one provider at a time?I have seen that location from onLocationChanged has getProvider()to let you know who provided the location information so that I can know which provider is actually finding a signal and turn off the others.
I have a program that monitors incoming SMS's, and I want it to monitor them full-time, so I registerReceiver with a Broadcast receiver that I've created. The problem is, if I want to unregister that receiver, I can't unless I know the original Broadcast Receiver class I registered. This is not a problem if I set it to stop when the program stops, but I want the receiver to keep running, only stopping when the user specifies. EDIT: Or is there a way of "Storing" the Broadcast Receiver class that I've created, such that when onDestroy is called it can be saved and when create is called again it can be pulled out.Is there any way of doing this?
