Android :: Capture Changes Of A CheckBoxPreference In Development?
Nov 24, 2010
I'm trying to learn how to do live wallpapers for android. I've got it working and now I want to add a couple preferences. So, I've created a preference activity and followed all the examples I could find.
I can capture ListBoxPreferences just fine, but the 'onSharedPreferenceChanged' method is never called when a checkbox has been changed.
Is there extra code that has to be added for capturing checkbox changes? Is there a best practices way of doing check boxes in preferences?

I have a checkboxpreference called passProtect. When the user clicks on it, I want it to run a method "someMethod". How do I get it to do that?

I would like to have a checkbox preference that takes the user to a new (sub)preference screen if the user presses on the actual text (and not on the checkbox to the right).Just as the control under Settings -> Wireless -> Mobile Network Settings -> Access Point Names.

I have a Preference that enables a sync adapter, and takes a while to actually do its work when toggled. Consequently, when the user clicks the Preference, I spin off an AsyncTask to do the work. In the meantime, I disable the Preference and replace the check box with an indeterminate ProgressBar. I have all of this working via a hack involving a subclass of CheckBoxPreference that overlays the ProgressBar on top of the CheckBox.

I have a screen where you can enable/disable modules for my Android application.
For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines.
Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window.
I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, wherever you click on the line the checkbox is toggled.
So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox.

I want to use screenshot kind of application in my own application. So that I can take picture in any format and save it. There is one function getDrawingCache() which does that, but it only save picture what is available on the screen. It does not capture beyond screen if the picture is big.

i had an interview this morning for a job, and have an opportunity to earna great deal of brownie points with the business owners.They were thinking of purchasing some sort of electronic signature capture device (like fedex or UPS has when you sign for a package) for invoices.. BUT.I also mentioned my Droid Eris and how it can do so much. Turns out, both of the Owners have DROIDs lol.Anyways.. I want to know if anyone has seen some sort of application that can capture signatures, and either save an image to be emailed, or email directly from the app.OR does anyone know a DEV that could create something as simple as this, that I can talk to and relay updates on the APP to the owners of this company.They seemed really interested in it, and I'm pretty positive it will show a good bit of initiative in saving their company money from the get-go (on my part)

I would like to create a video recorder and so far haven't figured out how to set parameters in order to successfully go through MediaRecorder.prepare() method. Executing the following method
public void start() throws IOException{
String state = android.os.Environment.getExternalStorageState();
if(!state.equals(Environment.MEDIA_MOUNTED))
{
throw new IOException("SD card is not mounted. It is " + state + ".");
}
File directory = new File(path).getParentFile();
if(!directory.exists() && !directory.mkdirs())
{
throw new IOException("Path to file could not be created.");
}
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
recorder.setVideoFrameRate(15);
recorder.setVideoSize(176, 144);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
this.state = VideoRecorderState.STATE_RECORDING;
}
it throws an exception on line recorder.prepare(). Does anyone know how to set parameters in order to be able to capture video?

I'm having trouble getting a screenshot. I installed the SDk, Eclipse, the drivers, enable usb debugging, like the instructions say. I open DDMS and it recognizes my phone without any problems. When I try to do a screen capture, it says screen not available. In the command box it says "timeout" and "truncated reply from ADB fb data". Does anyone know what I'm doing wrong?My phone isn't rooted and is running RC33. I'm running windows vista on my computer.

i was wondering if any of you had suggestions for a screen capture app that didn't require the SDK. If it didn't require me to root my phone that would also be a plus but i'll take what I can get.

As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread:
http://groups.google.com/group/android-developers/browse_thread/threa...
It is working; however, the audio is extremely poor too static for our needs. As a comparison, we did a similar audio file captured with audacity on a PC and it was much better. Has anyone been able to record high quality audio with the android dev phone? According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR:
http://developer.android.com/reference/android/media/MediaRecorder.html
According to wikipedia, AMR encoding is only 8hz. Is there a better option available perhaps a lower-level API compared to MediaRecorder? We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options. We defined the SD card in AVD manager).

I would like to be able to capture the video from an android phone camera, and then process this video. Processing involves adding a layer of AR to the live stream. Is this possible on android? Pretty sure it should be. I have looked at the android site [http://developer.android.com/guide/topics/media/index.html] but this seems to be concerned with video capture and storage. I would like to be able to play with the video pre-storage.

Android 1.6 supports video capture, however, not all phones will support video capture. Is there a way I can tell if the phone I am running on supports video capture or not?

One of the alternative app stores is asking for unaltered, unedited capture from the app as a video. Plus I'm also interested in cleaner video than I get by focusing a camcorder on an Android on a table. Who knows how to do that? I think I found some posts that indicate Mark Murphy may have solved this with a tool that goes through DDMS. If so, I'll get that tool and donate.

I'm trying to capture an image by calling camera utility from "MeidaStore.ACTION_IMAGE_CAPTURE". However, it seems there is only on resolution available 640x480, while the native camera support 8MB resolution.Any permission or extra param needed to get larger resolution option? It'd much appreciated if anyone can help on this.

I am looking for a screen capture utility that DOES NOT require a rooted phone.HOW IDIOTIC, suppose I want to screen capture as a user, to help a developer do documentation? This is absurd that there's no apps for the rest of us honest users.there's something if I connect it to my PC. C'mon, I don't have to connect my home PC to some other computer to take screen snapshots. I want an app that works on the phone itself, and does not require root access.

Is it possible to capture an image without showing the camera preview?, i have a requirement that i should be able to capture the image from a thread or from a service, without disturbing the foreground application, where i do not want to show the camera preview, but still i want to capture the image in background and store it in the device. So is it possible to do using the Android 2.2 SDK version?

Continuing with the question referred in the following link: [How can I capture when time changes in a TimePicker if the keyboard is being used?][1]
[1]: http://stackoverflow.com/questions/3380761/how-can-i-capture-when-time-changes-in-a-timepicker-if-the-keyboard-is-being-used/"How can I capture when time changes in a TimePicker if the keyboard is being used?"
I could solve the problem but it only works when you use the actual keyboard. If you use the soft keyboard I can't get it to work.
I am programming in 1.6 version of the framework.
PS: The fact that I've search everywhere for the answer and have not been able to find it tells me that this must be so very simple or very much complicated.
