Android :: SQLite - Detecting Limit Hit?

Oct 11, 2009

I have an SQL which uses something like "LIMIT 100". If the cursor returns 100 rows, is there an efficient way of distinguishing between whether the LIMIT caused it or not? I suppose I could just call LIMIT 101 instead but I was hoping for a nicer way.

Android :: Limit Records Fetched - Sqlite Database

Apr 22, 2010

I am trying to fetch sms messages from inbox, sent items and drafts. I would like to do a pagination for my list view for that it's imperative that I fetch records in pages/chunks.

I am not familiar with sqlite which is the database I understand android use to store the data. Can someone tell me how can I restrict the number of records I am fetching by using contentResolver.query?

Also what is the way to pull the sqlite database file onto my machine and browse/query it locally to experiment or see data on my machine?

Are there any other better ways to implement pagination in android?

Android :: Retrieve Single Column Of Last Row In Sqlite / Droid Using ORDER ID Desc Limit 1

Nov 10, 2010

I'm attempting to create a method that will allow me to retrieve a value from the last row of a database, and then insert it into an EditText field. (This is a value that the user will not change all that often, so it would be helpful if when they do set it, it stays set when they come back to it).

My method, based on a similar method I have for getting the total of a specific column, is as such. code...

If I run the program without this statement, it works fine and the value saves to the db. As soon as I try to run it with this, I get a force close. Any suggestions?

Android :: Detecting Where Has Been Touched

Jul 7, 2010

I have a single bitmap with several individual pictures in (each one is an option) and I would like to detect when the user touches these pictures. I am using the event.getX and event.getY to detect where is pressed, I know the top left X Y and bottom right location of each of the pictures. What is the best way of detecting which one is pressed? (i.e. tieing up the event press and which picture has been pressed?

Android :: Detecting Hardware Capabilities

Jun 3, 2009

There are return values and such that allow handling if SensorManager sensors and location providers aren't available, but what about the camera and microphone for audio recording? Is there a way to detect those in software, or are we just to assume that every device running Android (even the rumored set-top box) is going to have a camera and microphone and try to use them?

In the case of the camera, it would seem that returning null would indicate the lack of hardware. I don't know if that assumption is valid or not, though, considering it isn't documented as such.

In the case of the microphone, though, I don't see anything that could possibly be checked. The same goes for the camera if you're wanting to do video with the MediaRecorder class.

Android :: Detecting When Launched By An Alias

Sep 2, 2009

I'm trying to figure out how my Activity can detect if it was launched by an alias as opposed to by the main icon.

Is it possible to do this?


alias1 and alias2 appear as expected in the Launcher, but I don't see any way in multipleEntryPointTestActivity to tell which of these icons launched the application.

Android :: ScaleGestureDetector Not Detecting Gesture End

Oct 31, 2010

I have hooked in a ScaleGestureDetector to an OnTouchListener as instructed in Android documentation. For some reason the ScaleGestureDetector does not always detect end of a pinch gesture. This happens mostly when pinching fast from large to small.

The effect is that after I have released both fingers the detector does not fire the gesture end event. If I touch the screen with one afterwards it still thinks I'm continuing the scale gesture (keeps firing onScale events). I have to do another gesture to get the detector to fire end event.

I have added logs to the OnTouchListener and when the scale gesture gets stuck I still get motion events normally when using one finger and event.getPointerCount() is 1.

I have made sure that I don't have any other listeners intervening. View that has the onTouchListener is not the only view on screen but this effect happens also when I'm very careful to begin and end the gesture inside this one view.

Is there any way to improve the end detection?

Or if there a way for me to manually set the ScaleGestureDetector to fire onScaleEnd and change scaleGestureDetector.isInProgress() to false?

Android :: Detecting Which Drawable Folder Was Used

Nov 26, 2009

Is there a way to detect whether a image was pulled from the folder res/drawable or res/drawable-hdpi?I am trying to save space and have a program that is using some hdpi bitmaps and some mdpi bitmaps. When an image is placed in drawable-hdpi it automatically replaces the mdpi version. I need to know when this happens beacuseI am using bitamp.resize() to fix the image sizes.The problem is that the getDensity() method (in the if statment after the && ) returns the screen density and I need the original bitmap density. This allays matched the screenDPI and returns false. I have a lot of artwork and do not want to duplicate everything for every size screen. I am trying to just create hdpi bitmaps for the ones that don't look good when re-sized.

Android :: Need Detecting Area Code

Oct 20, 2010

I'm trying to find out if the user is still within range of his own area code. Detecting roaming doesn't solve the problem since the user may still be in the same network with a different area code. I thought about getting the user's coarse location to find the city he's is in but this approach needs Internet access and might not be fast enough (this is done as the user is making a call and needs to finish before the call is made). Is there any way I can do this with just the info from the cellular network?

Android :: Detecting Outgoing SMSs

Jun 6, 2009

I am writing a Security-oriented application for Android that is supposed to detect abuse of SMS sending.

In my work I encountered the problem of not being able to detect outgoing SMSs sent not through the use of conventional applications, i.e. merely by using SMS Manager's sendTextSMS method.

The conventional SMS applications add the contents of the sent SMS to the SMS Provider after they send it but I can assume that malicious applications will not do that... and neither will they provide the pending intents to the sendTextSMS method to be broadcast upon sending/ delivery.

My question is, is there any way I can detect the sending of the SMS without relying on the SMS provider?

Android :: Detecting When Outgoing Is Accepted

Oct 16, 2010

As far as i know there is no way to detect when an outgoing call is accepted at public API level. I can detect incoming calls (with PhoneStateListener), outgoing calls by NEW_OUTGOING_CALL intent, but i can not find a way to distinguish the dialing and connected phone states.

For this I wanted to know whether it is possible for me to get intimated when a call comes to the phone and is it possible to intercept the same.I tried to go through quite a few forums but could not get conclusive evidence on how to achieve this.Does anyone have an idea whether this is feasible and if so then how?

Android : CTS Not Detecting Device After Restart / Way To Fix

Feb 18, 2010

I am testing an android device with eclair using the 2.1 CTS version. When CTS completes a set of tests and restarts the device a "device disconnected" messages appears on the CTS console. However after the device completes the restart to the android home screen CTS does not detect that the device is back online. I have to physically disconnect the USB cable and re-connect it. Do you think this is a device side issue or a USB driver issue on the Ubuntu machine (intrepid) where I am running the CTS?

Android :: Detecting Socket Connection Failure

Apr 1, 2010

I am working on an app that uses a Socket to connect to a controller over TCP. The protocol library was written in Java and I am implementing it in android via a Service. where the Connection class is a Thread that handles the communications with the controller. It's where the Socket lives.I'm using the Preferences mechanism to store the IP and Port. If I feed the Socket the correct IP and Port, the Connection Service works beautifully. However, I am trying to simulate a user entering the wrong information and having the connection fail. The ultimate goal is to present a dialog and offer the ability to "reconnect" or "update settings". However, when I enter a wrong Port number, the application simply hangs.I was under the impression that Threads executed concurrently so I've tried moving the call to start the Connection Service to a Thread, but it still hangs the application.

Android :: Detecting Ad Hoc WiFi Access Points

Feb 9, 2009

I am developing an application on the android platform. The app performs continues WiFi scan and sends information about the list of visible access points to server.

Android :: Detecting If System Apps Are Running

Oct 11, 2010

We are trying to automate our QA process. We make wallpaper apps for Android. Once an app is installed, is there a way to figure out if the application is running since these have apps don't have a main class which we can check by doing a ps on android shell. I think keyboard/language apps would face a similar issue

For eg. If I install tetris and run it. Its main package will show up in shell ps. But the same is not true system apps in android.

I'm trying to detect the focus/pressed color for button and other elements. This is needed because I'm developing new components and it's important that those look as part of platform. Those colors are ORANGE on android sdk and GREEN on HTC SenseUI. If I could detect that color my component will look as part of platform on both version. Does anyone knows how to do this?

It's possible to create "selector" which uses custom image for default state and platform default for focus/selection. To do this follow the steps:...........................

Android :: Concept For Detecting Changes Of An Opened File?

Sep 22, 2009

I wrote an application for video recording which stores the recording to a file. Currently I am looking for a way to implement some kind of "listener" to listen for file changes.
The concept I would like to implement is the following: Check the file on a set period of time (for example one second), extract changes (get the data that was written in the last period) and do something with these data.

I would be very thankful if anyone of you could give any suggestion or point to any useful resource that could help to solve the given problem.

Android :: Detecting Clicks On A Google Maps Overlay

Jun 15, 2009

I would like to put a bunch of dots on a google map, and have the appropriate listener called when one of them gets clicked.All i seem to be able to find is to get the location at which the click occurred, and then iterate through the dots until I find one that I think matches. Is there no listener for an arbitrary shape, like a drawable? I feel like this might be a Java question more so than android, but hopefully someone can still answer it.

Android :: Detecting Shake Movement Without Draining Battery

Sep 10, 2009

I would like to detect shake movement in a service that is running in the background, even when the phone is not currently being used. Is it true that the only way to do this is to hold a wake lock? I suppose this would consume a lot of energy and drain the battery very fast.Is there no way to wake up the phone whenever a shake movement occurs? Maybe with the native sdk? I would imagine the accelerometer causing some kind of interrupt.

Android :: Detecting Navigation Input Method On Device

Apr 1, 2009

Does anyone know how to detect what primary non-touch navigation method (trackball, dpad, wheel, etc) a device is using within the code?

I know that an app can structure the /res/ folders to detect it like this: /res/ drawable-nonav drawable-dpad drawable-trackball drawable-wheel

But what if I want my app to behave differently depending on the navigation input method- is there a way to do this in the code?

Android :: Detecting And Changing Programmatically Data Connection

Jun 14, 2010

I know that unfortunately detecting and changing programmatically data connection (GPRS/UMTS) on vanilla Android is not possible, and the common workaround is to edit APN settings. This is hardly a nice solution. However on my device (Xperia X10) I have an additional setting near "data roaming", that allows to enable or disable MMS and data. I suppose that this is a personalization made by Sony Ericsson, and maybe even other vendors have something like this. Is there a way to access this setting?
