I was wondering if there is a way to set the minimum voltage cutoff (when the device forcefully shuts off), if it's device specific then we are working with the HTC Aria. The reason why I ask this, is that I have a device with a 12 Ah (that's 12,000 mAh) battery. Now I'll be straight, I'm an EE so software is not my forte, I work with analogue circuits, not software. So my knowledge of programming is nil. I was going to go the extra mile and make a flyback regulator to keep the voltage at 4 volts all the time (I can get it to work down to .5 volt if I wanted), but did not want the extra mass. (Already have 3 long C cell size sized batteries, don't need a PWM board on top of that). If this is the wrong thread, call me a noob and kick me in the nuts a few times, will ya? BTW the minimum voltage we are working with is 3 volts.
View 3 Replies View RelatedI have trouble with finding my SQLite Database.
As we can access the SQLite databases on a running emulator like below:
adb -s emulator-5554 shell
sqlite3 /data/data/package_name/databases/database_name
But what if I am testing my application on real device(HTC Here-Android) ?
where does i find my database?
I have an minor issue when taking a photo. I have a button that invokes the camera, successfully takes a photo, and returns to my entry form. My only problem is the database leak that occurs when pressing the button to call the camera.
My code looks a little something like this.
code:..........
I run :

In the onCreate of the Activity or Class that I am calling the camera in. I have not coded in mDbHelper.close(); anywhere not sure if i should when or where. I think i would rather just leave it open while capturing one image.

Everything seems to be working fine, but i would defiantly like to avoid any issues amongst the many android devices out there.
When I exit out of an app the screen is blank for 30 seconds or so before my widgets and icons reappear. I had it back in November 2009 and I still have it after 2.0.1 and 2.1 and 2.2 and the other 2.2. I see a million threads here and on other forums asking about it. Just checking in to see if there was ever a solution discovered. Like all of you, I can always bring them back with a hard or soft reset.
I'm just wondering if anyone has found a way to prevent it from happening in the first place. I assume that it's related to available memory or processor or something, so every once in a while I think "I'm going to streamline this thing and give it all kinds of available memory" and it doesn't work. I kill all widgets and go to vanilla wallpaper and it still happens. Anyone figure this thing out?

I am writing an application that listens to phone calls and perform some tasks when phone call arrives. The Application contains one activity which includes 2 buttons 'Start' and 'Stop' (where starts register the listener and stops unregister it - see code below).
The problem starts when the application is closed ( onDestroy is called ). If the user pressed on the start button and exit from the application the listener still working (which is the expected behavior) but from now it is impossible to unregister the listener since launching new instance of the application create new instance of phoneListener.
My question is:
1.Is there better way to implement my requirement?
2.Can I save the phoneListener object and reload It on application creation?

View 2 Replies View RelatedI need to statically link the 3.6.2 version of SQLite against my android application due to a bug that affects the dynamic library bundled with Android < 2.2. I've already compiled and installed 3.6.2 on my development machine, but I'm not sure how I go about linking it to my Android app (developing with Eclipse).
I'm not familiar with building and compiling options, so if someone could walk me through step-by-step.
In an Android application, we usually got the "Force Closed" error if we didn't get the exceptions right. How can I restart my application automatically if it force closed? Is there any specific permission is used for this?
View 2 Replies View RelatedA customer asked me to create an android application for their internal use. Essentially it would some sort of mobile terminal for a special chemistry database.It doesn't make any sense, to distribute this application via "Android Market" since it is only useful for special users and payment wont be done per installation but for the whole contract.Is there any other way to distribute android apps besides the market? Maybe by putting them on a web page? Any hints appreciated since i couldn't find anything on the web.

View 14 Replies View RelatedI want to add a big feature to an application i am developping, but as this feature interest few people and is quite independant from the main part, I would like to put that in a seperate "plugin" application.Does anyone knows any design patterns, snippets, "reference" examples about such design?In particular that separate plugin application should be able to access some tables in the main application DB. Is it possible to do that without broadcast receiver? - the main application uses a TabActivity: is it possible that a the tabactivity instanciates an Intent Activity that is part of the plugin? - does the plugin can access main application preferences (not sure this would be necessary, but better to anticipate the question!) is it possible from the plugin to access main applications ressources?At least the 2 first points are mandatory for me.

View 3 Replies View RelatedI have a app in development. It write data to a SQLite database. I've tested the app on my NexusOne over the weekend and have a bunch of data now in the database. I'd like to copy the database off of the phone and onto my dev machine.
I've tried to use adb pull <path to mydatabase> <path to my local machine> but it gives me a Permission Denied error.
Is there any tool that will allow me to browse databases on my Android device? Something like Sql Management Studio - you know GUI tool that displays databases, tables, row in tables, etc.
I'm using Eclipse for development (if it is important for plug-in suggestions).
I am currently running CL14 stock with Open Home and I wanted to let you security conscious folks know about a security issue I discovered. I hit the end button and pulled up my phones lock screen. Decided to test the new emergency dialer and when I pulled that up Open Home had force closed. When I hit end it returned me to the main screen w/o me entering my combination. I assume this could happen with any force closed app so although it's a rare issue that something FCs in the background it is possible and is a security issue. Just a heads up.

I'am trying to use a large DB file. It's as big as >8MB. I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above.
However, When I debug, it keeps showing IOException at

I suspect it's caused by trying to read a big file. If not, I have no clue why.
I tested the same code using much smaller text file, and it worked fine.
Can anyone help me out on this? I've searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy.
I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don't think this will work either.
Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly?

View 2 Replies View RelatedCurrently a team of developers is working on Android application and during the development process testers already have to test the current state and report issues.
So far I have simply installed the application by connecting the tester's device on my pc and hit run in the IDE. This way we waste a lot of time if an application has to be installed on multiple devices multiple times daily.
What I would like is to send the testing team the .apk file and let them install and run the application by themselves.
Does anyone know what's the best way to do it?
