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.

I have a query that selects rows in a ListView without having a limit. But now that i have implemented a SharedPreferences that the user can select how much rows will be displayed in the ListView, my SQLite query doesnt work. Im passing the argument this way:

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?
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?
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?
View 2 Replies View RelatedThere 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 Camera.open() 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.
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?
CODE:............
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.
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?
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.
View 2 Replies View RelatedI'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?
View 7 Replies View RelatedI 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?
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.
View 4 Replies View RelatedI was trying to come up with an app that works on the call that a user gets on his phone. 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?
View 2 Replies View RelatedI 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?
View 2 Replies View RelatedI 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.

View 5 Replies View RelatedWe 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. xyz.abc.Tetris. But the same is not true system apps in android.

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.
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.
View 3 Replies View RelatedI 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.

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?

View 2 Replies View RelatedI 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?
