The Android code on how ContentProviders work, and to me, it looks like any ContentProvider I query actually gets placed entirely in the memory of the requesting application. Are they really stored in the querying application's memory? For some reason I thought the cursors were lazy.

I am currently writing an app that asynchronously populates a ListActivity. Therefore the query on my ContentProvider is done by a separate thread, not the UI thread. Furthermore the ContentProvider is synchronized by a service in the background. Since this may be a lengthy operation the service also uses its own thread. My question now is: Do I have to do some locks by myself to support concurrent accesses by both reader and writer (in the ContentProvider) or is there already taken care of when inheriting from ContentProvider and implementing the methods? Which thread runs a ContentProvider? Some Binder thread or the calling thread?
View 4 Replies View RelatedI have written a content provider over a database table which essentially captures phone contacts information.
So at a point of time, in my application code, I want to query the android contacts content provider, and insert that information into my Database table through the content provider.
For this I have to query the content provider from android, get the cursor, loop over the android contacts, for each contact, insert using my URI, this becomes very bulky. Is there any work around? A bulk insert mechanism of some sort? Or at least pass an object to a URI, which can be the android cursor.

I just switched from Ubuntu 8.10 to Ubuntu 9.04 and noticed that Eclipse Content Assist isn't working anymore. I tried the following variations on Ubuntu 9.04: Eclipse 3.4.2 or 3.5 (cleaned / reinstalled) with ADT 0.93 and Android SDK 1.5r3 Using Sun Java 1.6. No combination works. I've reinstalled everything a bunch of times. I have another machine with Ubuntu 8.10 and Eclipse 3.4.2 with ADT 0.91 or 0.93 and Code Assist works for all those. I just refuse to develop without code-assist and I know lot of people would agree with me on that.
View 2 Replies View RelatedI had some fairly simple code in my app to invoke Edit Contact activity on a known good contact index that worked in Android 1.6 but is broken for me now in Android 2.1 on the Droid. I built a sample activity/app 'EdCon' to show this:
package com.jbh;
import android.app.Activity;

When I run this on my G1 running 1.6 it works as expected i.e. brings up the Edit Contact screen for the known index and then I can hit BACK to return to "Hello World, EdCon". Code...

The problem is that I use YouMail, and apparently *73 is the code for disabling the *71 busy/answer forwarding as well. It seems stupid that verizon used one code to disable 2 different features. How do I disable the *72 feature w/o disabling the *71 one?

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)

Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...
I have google voice and use it for every phone call I make. I heard that there were issues with several gvoice updates, so I haven't updated google voice since 0.2.8 and it is working just fine- every call connects, no problems. Is it worth updating to the newest version of google voice with push? For those of you with 2.1 on your Eris- does google voice work for you?
View 12 Replies View RelatedI'm trying to determine whether or not my phone is defective, or if this is a current problem with the Cliq.
Of the apps I've downloaded, only a few of them have worked. Of those few that work, some don't work right. Has anyone had problems with these apps crashing on them, or just not working correctly?
- Nice Battery (see description at bottom of: My Ultimate CLIQ settings (so far))
- WeatherBug (kept showing the wrong location, crashed when trying to change location)
- Snake - doesn't work just says its "paused"
- RingDroid - crashes when I select the "Facebook Pop" button
- Layar - screen is rotated 90 degrees at all times
There have been others, but usually I just uninstall them right after discovering it doesn't work right.
I've had an HTC Desire on Orange in the UK for about 6 weeks and it is having persistent problem. Firstly despite having a strong 4-bar out of 4 signal, online services and the internet do not work at all when a 3G signal is being received (e.g. news, weather, all widgets, internet, email etc).Calls and texts do work however with a 3G signal.But when a 3g+ signal (HSDPA) is being received, all internet services as above work fine.However, when a 3+ signal is being received, the phone does not make or receive calls or text messages, and often fails to send texts. Calls I make immediately shut down (bleep + �call ended�), and incoming calls from other people go straight to answerphone. Also often when turning the data connection on/off, it freezes and has to be rebooted, and turning airplane setting on and off does not fix the problem.
I have also tried the different network settings (GSM, WCDMA, auto, etc). �GSM� sends and receives calls and texts but doesn�t work (or is incredibly slow) with internet, and �auto� and �WCDMA only� show the problems as above.I don't think this is a network/coverage issues as, as I have seen many people reporting these same issues on other networks and in other parts of the UK, and I have read that other people are having to manually turn off HSDPA to be able to make calls (using an app?). Even if I can stop HSDPA from connecting to make sure the phone works, I still can�t use the internet at all on 3g � even GSM works better!
Finally, when I connect to a bluetooth device (e.g. car and headphones) the phone will connect briefly, and then randomly disconnect. I have also seen this issue reported elsewhere.I very much like the phone and don't want to get rid of it, but these problems are making the phone unuseable.Also I don't know if I should be contacting HTC or Orange about this. Will the upcoming Android 2.2 fix these problems?Anyone know how to fix this or if I need a new handset? Are there any apps that can help? Also does the Nexus One have these problems and are they fixed by Froyo?
So I made a discovery - my dialpad doesn't work during a call. Even if I bring it up via the softkeys, the numbers don't register a tap...anyone. else have this issue or is it just my phone?

a) Speaker doesn't work in call (very weak). works well in ringtones etc.
b) Scrolling contacts by letter doesn't work.
Other than that this is a leap forward, especially with the overclock options!
Both bugs, as well as others, fixed in 1.6.3.1 update!
Could it be at all possible to code an app for the G1 that would allow you to say, slightly jerk the phone to the left or right, and that gesture would act as a phone shortcut? Since the phone is equipped with an accelerometer, it seems like it could be possible to have it behave a certain way, depending on certain movements. So say I wanted to start writing a SMS message. Without even having to touch the screen, or any of the buttons, I simply just jerk the phone slightly to the right (or any sort of gesture), and then up comes the compose SMS message menu.
