I can read settings like this, for example: final String mytest = System.getString(this.getContentResolver(), System.AIRPLANE_MODE_ON); but can't seem to write to settings using putString, no matter what I've tried. Maybe it is the scope of this.getContentResolver()??? I'm a newbie, so who knows, maybe it can't be done, or it's just syntax? Currently the code is in the onCreate of an Activity class.

Can i pro-grammatically get a list of content providers extant on the system?
View 7 Replies View RelatedIn my app i need to read the data at a content provider before the system actually initializes. Probably what i understand is that a boot complete intent would launch a homescreen activity.Exactly before the system initialized i want to see the data provided by the content provider and use it.
View 2 Replies View RelatedNot sure of the absolute utility of this but seems as though it should be possible and useful. Can you extend ContentProvider to provide URIs representing new queries (i.e., joins across multiple tables not specified by existing URIs) for an existing system database? The alternative seems to be that I need to write a series of cursor queries then join them -- seems like a lot of unnecessary code duplication.
I have been trying this for the contacts database as an exercise, but no love so far. The crux seems to be that I cannot open a database in another package during the setup phase. Am I just completely out in left field here? It's possible as I am new to both Java and Android.
I am an Android app developer, and I have purchased a Nexus One device which I use to continuously test my developed Android applications.
Background: ----------------- One of the applications I developed uses a native shared library (e.g. myNativeLib.so). Only my application loads & uses this native library. I had developed this app before Android NDK came out. I pack my native library into my apk's 'assets' folder, and during my application start- up, I extract this native library from my package's assets folder to my app private directory (i.e. <assets> -> /data/data/<myappprocess>/ myNativeLib.so). Then I use System.load() API in my application to dynamically load this native library.
Problem: ------------ This application was developed during Android 1.5 (i.e. cupcake) days {I didn't have the Nexus One then}. The above procedure has been working without any problems right from Android 1.5 to Android 2.2 (i.e. Froyo). I have also tested the same on my Nexus One for Android 2.1 (i.e. Eclair) and Android 2.2.
The problem began the moment I recently upgraded my Nexus One to Android 2.2.1 via the FRG83 system update. Now, whenever I try to load my native library, I get the following error:
D/dalvikvm( 3653): Trying to load lib /data/data/<myappprocess>/ <mynativelib>.so <some address> I/dalvikvm( 3653): Unable to dlopen(/data/data/<myappprocess>/ <mynativelib>.so): Cannot load library: link_image[1995]: failed to link <mynativelib>.so
What I have Tried: -------------------------- 1. I tried my application using Android 2.2 SDK (emulator)...it works, no issues. 2. I checked out the latest froyo & android2.2.1 source code from Android open-source, built & tested my application + native lib using the latest froyo source...it built & ran, no issues. This should've taken care of any changes in the native code dependencies between Android 2.2 & Android 2.2.1 3. I even checked Android 2.2.1 source code for dalvik (java System & Runtime classes) + bionic (linker & dlopen sources) between Android 2.2 & Android 2.2.1 (using source checked out from Android open-source), but couldn't find anything consequential 4. I am unable to return my Nexus One to Android 2.2.
Looks like I've run into some breakage from 1.5 to 1.6 after all. I am registering location listeners with LocationManager.requestLocationUpdates() With GPS as location provider, I run into a problem with navigation stopping by itself after a few seconds, just to return, stop again, in an endless cycle. I haven't seen this prior to 1.6 Donut and I have no clue what might cause this problem.
Here's the Logcat output:

A web research for these logs didn't turn up anything (which is unusual in my experience), so this leads me to post the question here wondering what the root of the problem might be.
I implement ProviderTestCase2 to test my content provider functions. And when I insert huge number (about 10000) of data, the insert, delete and update functions are fine. But the query function will have SQLiteDiskIOOException: disk I/O error. And the data number limit of causing the exception is about 5000. Is it bug of content provider?
And there is another problem. Each of my data has different priority. When I sort my data by priority, its no problem. But when I change priority of some data and then sorting again. Sometimes I will get incorrect result and I'm sure its not logical problem of test program.

I would like to give the users of my app the possibility of selecting a language from within the application. All languages are supplied the standard way via the values resource directory. However, I don't want Android to select which resource directory to use but let the user decide instead. Any ideas how to accomplish that? The rationale for this: - some languages are not supported by the Android framework and can not be selected as a locale via the system settings - if you buy a phone in Spain, it will typically not have a system setting for Russian language, if you purchase in Russia, you will have that setting. So a Russian person in Spain would prefer using the Russian language included with the app, but can't access it

when my widget is pressed it goes to an activity with a blank background to change the system settings. one of the settings that are changed is the display brightness. this is the code i use to change the display brightness. once i change the settings i call the finish function to exit the activity so i am not stuck there after the settings are changed.

Context: Today im investigating how works android classes:
android.provider.Settings.Secure and android.provider.Settings.System
both works over settings.db into
data/data/com.google.android.providers.settings/databases/settings.db.
There is something that surprised me:
When I had never changed one of settings, for example LOCK_PATTERN_ENABLED, the method:
getString(ContentResolver resolver, String name) returned null.
By default lock pattern is disabled when i activated it, method returned 1 and then when disabled returned 0.
My question: is true that when you havent changed the value of a setting, the system goes to look for its default value out of settings.db? and is true that this value at settings.db until you change it is null?
I've read some post about it, but no one working against api. For who may be interested: [URL] .......
I decompiled Settings.apk, SettingsProvider.apk and Phone.apk. There you can find some bools.xml where are stablished default values for some settings I've not found yet every setting I need.
Me and a friend are trying to port a system app from the same phone but two different roms. Here's the situation. The phone is zopo zp998 and it comes with regular Android 4.2.2. Zopo is making the exact same phone for the Chinese market with on OS based on Android 4.2.2 that's called YunOS and it doesn't have Google account support so it's not usable outside China.
The YunOS has a black screen gesture feature that you can activate in the settings under display and then while the screen is Black you can make symbols on it with your finger and open specific apps. For instance if you draw the letter C the dialer will open.
My friend was able to find the system app for the gestures in YunOS and all its library files and put it in his rom. When the phone boots we can see that the gestures service is running fine but we don't have the option in the settings to activate the app. we can use on how to transfer a system setting and app like this? Is there another app we can use to trigger the on and off of the app?
I am from Italy and own a samsung i9000 s.bought from a wind shop ( but unlocked to all networks ). When I enter Kies and try to do an update it says that I already have the latest version. I checked and mine is Eclair 2.1 . was wondering if anybody know if WIND have the release of froyo 2.2 available on their network. I am moving my number to TIM mobile operator tomorrow anyway. Maybe some ideeas on that? I would really really like to upgrade as I have heard that Froyo really works alot better on sgs . Really now but for a phone that I have paied 550 euros I expect no lag and better start time of apps...and well alot of stuff. If that doesn't happent I'll just ask for my money back and go for the Iphone 4. not really what I want but my Iphone 3gs was performing better than this newer faster ( 1ghz..and 512 ram ) Samsung Galaxy S. SO PLEASE do cooment and let me know about what you think.

I'm a big fan of Toggle Settings but my one wish would be that it could toggle GPS. From what I understand, the security of Android doesn't allow any app to turn GPS on/off. My question is, since installing Mobile Defense as a system application allows it to turn my GPS on, would installing Toggle Settings as a system app enable the same feature? Does anybody know of a way around this or another app that is similar and can toggle GPS settings?
View 3 Replies View RelatedMy OEM's preloaded rom is almost-nearly stock, apart from 2 things:
1. White background on "system settings" interface and not the default holo. Cant that be changed to default?
2. Ribbon effect instead of flash-light in holo effect, which tbh is quite annoying, because the ribbon effect is also quite large and in slower animation speed so that,s 1 second of frustation everytime i scroll to the end. (Yea, 1 second isnt much but, add those up and it gets annoying really fast)
How can these be changed back to default without installing a custom rom?
I am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.
I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.
I just posted this in the regular android discuss group but I do believe that developers should read this as well. This directly affects you as well. This first began with my personal experience, I have an HTC Magic and I'm at version 1.5 a friend of mine has a g1 while another just got a Milestone. The issue is one friend can't understand why one phone can see this app and another can't or why one phone can do one thing that another can't, Their both running android whats the problem (ex. The Milestone has maps 3.3.1 the G1 has old Maps 3.1). I'm getting tired of explaining that even though they are both androids one is more up to date then the other and there really is no way to update. Even "IF" you rooted the phone you have to deal with bugs and ports its ridiculous. Now I love Android and I want to see Android KILL iPhone and eventually Symbian and I DO know that this is not necessarily Google's problem but it is indeed a problem that affects Google and it's users wanting to get the full Google Experience. I recently read a PC World article stupidly titled Android doomed to self destruct which I do not believe and its at this link: http://www.pcworld.com/article/189969/google_android_is_doomed_to_sel... but I realized that I am not the only person that sees this. Today there is an article on Slashdot as well as 2 on infoworld. We need to fix this at least some kind of update system that does not rely on manufacturers or at least forces them to act. Devices are releasing today with android 1.6 and if I research I'll probably find a few releasing 1.5. HTC is still pumping out Magic's with this old firmware, it's just getting very messy all across the board. Is there any suggestion as to what can be done at least on paper, any ideas?
