Android :: How To Use SQLite Functions?

Apr 1, 2009

I read in the documentation for SQLite that there should be some core functions and aggregate functions available, but I can't seem to use them in my code.. Can anyone help? Here's the documentation ad: http://www.sqlite.org/lang_aggfunc.html http://www.sqlite.org/lang_corefunc.html There is for example the function count() but how do I use it? I have tried to use it as stated below, but none of the functions in the documentation is available that way (i.e when I type "db." the list that shows in Eclipse documentation doesn't include any of the functions from the SQLite doc except from execSQL):

Android :: SQLite Creating SQL Functions

Jul 22, 2010

How does one go about adding a custom SQLite function from within the Android sqlite API? I have a function (written in C) that I'm able to add using the C API outside of Android as described here: http://www.sqlite.org/c3ref/create_function.html.

Android :: Key Functions Not Working

Jun 18, 2010

I have looked all over the place. Here in the forums, online, user manuals, etc. What I am looking for: When I am texting, I see above the "A" key is an alt symbol that looks like an arrow pointing to the right with a verticle line. It appears to be an ALT-function of some sort. What is it? What does it do?

Android :: Need To Sync Business Functions

Oct 7, 2010

New to android..been using WM 6.1 sync with outlook obviously seemless. Need the same type of functionality but it doesn't have to be with outlook. Looking for options to use for business. Being a small company I can go anyway I want, don't have any restrictions other than need to sync all with phone, laptop and desktop. Beginning to travel more so contact, calendar and task must sync (notes and a Today front end would be nice). I have tried Dejaoffice but I end up with 2 sets of contacts and calendars (Samsung and Dejaoffice) not to mention that the UI is lame (had just as good 15 years ago with Instant Recall). Don't mind rooting the phone if needed. So what options exist in the open source world? Love my captivate phone but need to be able to do business to keep it. Anxious to hear how the rest of the Android world does it.

Android :: Notes App With Specific Functions?

Jul 12, 2010

I've searched through the forums and tried a lot of notes apps, but I am yet to find one to my requirements:
- Should have widget support (I need to put some notes on my homescreen, not the note creation widget like 3bananas)
- Bluetooth sharing (or it stores the notes as .txt files on the SD card). Alternatively, it could sync with google in some way. If you know one that does these, please tell me. Else please tell me what app you're using, so that I can try it if I haven't already.

Android :: How Do I Prevent Certain Functions From Getting Stripped?

Aug 29, 2010

I have a static library that contains some JNICALL functions, i.e. they are expected to be called from the JVM and are never referenced by the shared library that links the static library. However, it seems like function stripping is exterminating the JNICALL function (it's not visible in arm-eabi-objdump -t). I'm working around it by adding a dummy function with an impossible condition that calls the JNICALL function, but that's dirty. I know that there is a link option to prevent certain modules from getting their unused data stripped, but what is it? And how do I specify that option in the .mk file? I didn't see anything immediately obvious in arm-eabi-ld. Incidentally, the function stripping doesn't strip out JNICALL functions in the shared library itself, but it will remove those from the static library that the shared library is linking. What's the reason for that?

Android :: Send And Receive Text Functions?

Feb 5, 2010

Any way to get at the Send and Receive Text functions of a phone? In other words, is there a way to transmit a text such that another phone, within range and using my app, could receive that text? Proposed app: The_Haiti_Phone: All cell towers and land lines are down. I would create a text msg to my wife's phone and my special app would send it. All cell phones in range would pass it on. When the packet's receiver's ID matches a cell phone's ID, the msg displays to the user. In summary, in a catastrophe, all cell phones with my app act as cell towers.

Android :: Instruction Count In Nested Functions

I'm not sure whether I'm badly misusing InstructionCount or there is a bug, but let's assume the first one for now. The simplified situation is like that: I have a function (say, foo()) for which I want to track the number of instructions executed and the function itself calls another function (say, bar()), for which I also want to keep track of the number of instructions executed, something like: Code...

Android :: Encapsulating Functions In Second Java File?

Sep 13, 2010

I've been messing with Android for a couple of weeks, i found many tutorials to follow, but i didnt find anywhere some "Style rules" to make the code looks better. I would like to know if its possible (im sure that it is, but dont know how to make it xD) to use more .java files to organize the functions. I mean, right now, i have myApp.java where i coded all my application, but is starting to grow so much, so i would like to separate some functions into another .java file. As i told before, im almost sure that this is possible, but i dont know how to link that second file so, can anybody help me?

Android :: Accessing Remote Services Functions

Apr 27, 2010

I ran into a problem with remote services. after i started and bound my service, i want/need to access it's functionality.

This works just fine if i work with buttons and onclick-controllers just as in http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/RemoteServiceBinding.html.

But actually, i need to access the services functions DIRECTLY after binding the service, like:

CODE:......

If i access the service function "getDataFromService()" in an onClickListener, it works perfectly. how do i access the services functions directly after binding/starting the service?

Android :: Advanced Music Player Functions

Sep 1, 2010

I'm fed up with the stock player on my Samsung Captivate, and I have tried both doubleTwist and Cubed (now called Rockon?) and neither has impressed me much. Thus, I am looking for something with more functionality.I have two main requirements (requests?):

1. Need some way to rescan my library without restarting my phone.

If I add music from somewhere on the internet or from an app, I want the app to be able to see that something has changed, scan my music again, and update my library.Now, all I can do is either restart my phone (sometimes works) or connect it to my computer and do it manually.

2. ID3 tag editor

Sometimes you notice an error and want to change it. I have a separate program to do this as of now, and I would love to do it within my music app. It just makes sense.Now I've read about MixZing, as it satisfies #2 and everyone seems to like it, but I'm worried about #1.Anyone have any personal experience with MixZing or another player that would implement these two things?

Android :: Telephony Manager Functions Don't Work / What To Do?

May 29, 2009

I have low expectations that this message will get any response as it seems that Google developers do not like to address issues too close to the Android core and to strategic mobility applications. However, as they say, hope is the last to die.

I am really puzzled by the lack of response to queries about issues with some TelephonyManager functions.

Specifically, there have been a number of requests in the past, including mine, about

getNeighboringCellInfo()

As per the link below, getNeighboringCellInfo() is a documented TelephonyManager function available to application developers.

http://developer.android.com/reference/android/telephony/TelephonyMan...()

Yet, getNeighboringCellInfo() does not work. Any attempt to call it in an application results in application failure.

What is the problem here? If Google does not want application developers to use this function (I cannot fathom why that would be the case), then please remove it from TelephonyManager, and save all of us time and frustration.

It's really puzzling that for such an open platform Android has so many secrets and rules.

Android :: Preventing Functions From Being Stripped From Static Library

Aug 23, 2010

I have a static library, Foo, that is used by a shared library, Bar. Bar is the native shared library loaded by my Android app. Foo contains JNI functions that are only called by Java code and not by any C++ code in Bar. Because of this, those JNI functions get stripped out of the static library (Foo) when the shared library (Bar) is built. I'm currently using a slightly hacky method to prevent that from happening.So, in this case, is there a way to tell the compiler to not strip the JNI (or any) functions out when linking?

Android :: Java Timers - Functions Called Not Completing

Mar 13, 2010

I have a TimerTask task calling a function onTimerComplete() in its run()

onTimerComplete() looks something like this:

CODE:...............

I make a Timer t and I schedule the TimerTask with t.schedule(task, 2000);

The problem is, when the timer is up and the task runs my onTimerComplete() but that function does not finish. It runs myFunc1() but never finishes it nor does it ever call myFunc2()

However, if I call onTimerComplete() directly, everything works.

General :: How To Access Core Android Functions Like App Switching

Jun 28, 2013

Is there any way to access core Android functions like app switching (holding down the Home button for a few seconds), to be used in other contexts? Similar to how you can access Activities from the apps installed and use them as Shortcuts.

What I'd like to do is this:

press Home -> bring up app switching interface
long-press Home -> go to Home screen

Basically I want to reverse the two functions that short and long pressing the Home button does.

If not that, I'm also interested in being able to access the "app switching interface" via a Shortcut (like a Shortcut you place on your Home screen), or via an app.

For example, you can long-press on the Home screen and add a Shortcut (different than adding a shortcut to an App) which basically includes various context functions of some of the apps you have installed. I want to be able to do this - add a Shortcut - in which the Shortcut I add launches the "app switching interface" that you normally get by long-pressing the Home button. That way I can put that Shortcut in Wavelauncher or wherever else I want to be able to app switch without the annoyance of having to long-press something.
