View 1 Replies View RelatedAndroid :: SharedPreferences Are Not Stored
Nov 21, 2010My problem is using SharedPreferences. I just created a <PreferenceScreen> which holds inside a <ListPreference> with an array of 5 different values. Very simple! The array of values are different numbers: 1, 2, 5, 10 and 30.Every time I change the setting, the application remembers that and I can see the setting I chose when I access the preferences once again (as an user). Now, in the code, when I retrieve the setting using the key (e.g. getString("delay", default_delay);), I always get the default value, it seems that the SharedPreferences does not find my setting. Can anybody help? I have read about SharedPreferences.getEditor().commit(), but that should be used only when changing settings from the code, not from the UI preferences.

Or put in another way, in what files SharedPreferences are saved, and how to view and modify these files?

View 8 Replies View RelatedAndroid :: SharedPreferences Bug When Writing Strings With Ampersands In Them
Mar 6, 2009I've just tracked down a weird bug in our app where SharedPreferences were failing between power cycles of the phone.
It turns out that one of the strings we were saving had an "&" in it. When I look at the xml that is being persisted I see that this is being encoded as && instead of just &
This means that when you come to read the settings back you don't get any values at all. Is this a known issue? I see lots of posts about preferences dissappearing, but nothing about this.

View 2 Replies View RelatedAndroid :: Can't Write SharedPreferences After Update / Sort It Out?
Sep 28, 2009I'm trying to prepare an update to one of my apps and I just realized that the updated version cannot read or write over the previous version's SharedPreferences.
Some details: * I'm using the 1.6 SDK and compiling for 1.5.3. * My androidmanifest.xml does not have a sharedUserId (I didn't think I need one if I was not sharing data between different apps).
How to reproduce: * Install my current app from the market * Run the app * Exit and save the setting - invoking SharedPreferences Editor commit (it's using MODE_PRIVATE) * Now install my new update (via a browser download) * Run the app * Everything works fine * Exit & Save *** Now reboot the phone * Run the app again ==> Can no longer access old data or write over it!!
Did I do something wrong? Is it because of the sharedUserId thing? Is it because of the way I'm testing - via market then browser? Why is LogCat reporting a UID change? ==> mismatched uid: 10031 on disk, 10046 in settings; Can I recover from this? I don't want to delete all of my users' data. error ...

Android : Can I Use Current SharedPreferences Tag To Store Values From PreferenceActivity?
Aug 5, 2010Currently, I'm using the following code across all of my activities in my app to store application level variables and carry values between activities..
prefs = this.getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
I didn't have a PreferenceActivity prior to this, but now I do and I am looking to store a few user prefs from this new PreferenceActivity in the same sharedPreferences tag, "MyPrefs".
I know I can access the PreferenceActivity SharedPrefs from my activities via
prefs = PreferenceManager.getDefaultSharedPreferences(this);
but I would like those values saved to my current sharedPreferences tag, "MyPrefs", but I'm not sure how to do this.
Android :: Can I Save SharedPreferences To File So I Can Have Multiple Instances Of The Prefs?
Jul 19, 2010I love how SharedPreferences work in android and I would like to know if there is an easy way to save them to another file so I could load a previous instance of the prefs and vice versa. Basically when you load this file, all the preferences would change to how you had it before at once. I want to be able to swap 3 or 4 different versions of the same pref keys in this way. Is there an easy way to do this?

Mar 9, 2009We have an online multiplayer game that saves some login information in the SharedPreferences. Our app is copy protected and everything was going really well until this weekend when we released an update for it. It seems that at least some of the people are having their SharedPreferences deleted when they updated too the new app. As you can imagine our users are furious because they're all loosing their profiles, and our ranking is dropping fast.
We've tried to reproduce this a hundreds ways but are unable. We're wondering if this could be related to installing a copy protected app over a copy protected app? Since that's the only situation we haven't tested and can't test.

Jan 12, 2010I've been pulling my hair out trying to achieve smooth scrolling in an OpenGL-based app on Eclair. It seems that no matter what I do, I cannot get more than 36 events per second (the rest is sent in history data which is useless in my case). This happens on both the emulator and the Motorola Milestone.Is this a hardcoded limit or am I doing something wrong? I'm implementing onTouchEvent on the activity and recording how many events are received per second and then send that info through Log.v to Eclipse. I also tried implementing onTouchEvent on the view instead of the activity and the results are the same.
View 4 Replies View RelatedSharedPreferences Not Stored After App Stopped
Jun 21, 2011My first android application has to do with showing activities at different times. All works fine ... except that when I retrieve the shared preferences in an activity activated from the notification manager, all my options are reset to default values.
Similarly, when I try to reinstall an alarm after the phone is switched off, all the previously stored shared preferences options are non-existent.Is there something special that has to be set in the manifest, or do I have to retrieve the context in a special manner? from a broadcastReceiver?

View 13 Replies View RelatedAndroid :: Background Processes Not Being CPU-limited?
Apr 19, 2010We were told that, as of Android 1.6, background processes were put in a Linux process scheduling class that limited how much CPU they would use. A few weeks ago, I ran a benchmark test that seemed to validate this claim.I have run more tests, and I am no longer confident in my earlier conclusion. I can get a background process to significantly impact the foreground process, more than would seem to be possible if the background process was, indeed, CPU-limited.

View 2 Replies View RelatedAndroid :: Dealing With Very Limited Data Plan
Nov 16, 2010I'm new to Android platform but not new to software development. We want (in our company) to create Android software to compliment our truck management software. Basically, it will do couple very specific tasks.
a. Send GPS updates to server.
b. Receive trip information.
c. Send pickup/delivery confirmation to server.
After evaluating i.e. platform and Windows phone 7 platform we came to conclusion that only Android has multitasking that works for us. So, Android it is but I have some specific questions.
1. Data plan we want to use will be very limited. Probably 5M/mo and no voice/text. I figured 5x1024x1024 = 5242280 bytes will give me 1k per transmission every 15 minutes (3000 transmissions per mo). It will leave 2M for other stuff that will happens every couple of days. Does my math look OK or there is lot of "waste" traffic? Our server going to be XML SOAP and messages sent will be just Lon/Lat in XML package. 1K will be OK? If I just calculate bytes it will be even less but I wonder if there is "minimum" packet size, etc. Any insight on this data limitation appreciated.
2. Because of #1 we need to "lock" device somehow so there is no other software that uses network. Possible? If so, what do I need to look for? I found already created app - firewall and it says phone has to be rooted for that.
3. Receiving trip information. What's the best way to accomplish that given my situation? Should I run some kind of listener? Will my phone have IP address or something? Or should I get small text plan and use that for this specific functionality? Can I receive text message in my own application?
So, as you see we trying to shrink $80/mo service to $15/mo service that will do big savings to our company but not sure if it's all possible with constraints we have. Also, we may just give discounts to drivers who have Android phone and will install our app but we don't count on that.
