I am writing an widget application for android.
I have a requirement where i need to disable the widget on some intent, i.e., I have the remove the widget from the android home screen and remove from menu options so that the user cannot add the widget further.
I have to enable the widget on some intent, so that, the framework automatically adds the widget to the home screen, by calculating the empty position available on the home screen, and the many option re-appears in order to add the widget further.
Please let me know if this can be possible..
Is there a way to lock the apps and widgets on the home screen and dock from moving if pressed like on jelly bean 4.3?
View 2 Replies View Related1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...

View 13 Replies View RelatedI'm new to Android application development and I'm currently experimenting with various UI ideas. In the image below, you can see a vertically scrolling list of horizontally scrolling galleries (and also textviews as you can see). I'm also doing some matrix and camera transformations which I will come to in a minute.
For the background of the list elements, I use green. Blue is the background of the galleries, and red is the background for the images. These are just for my benefit of learning.
The galleries being used are extended classes where I overrode the drawChild method to perform a canvas scale operation in order for the image closest to the center (width) to be larger than the others. The list view going vertically, I overrode the drawChild method and used the camera rotations from lack of depth dimension in the canvas functionality. The items in the list are scaled down and rotated relative to their position's proximity to the center (height).............
i'm trying to know the database space available. In J2ME you have getSizeAvailable(), but there is no direct replacement in Android, so i thought about doing getMaximumSize() minus database size, the thing is i just can't find a way to know the db actual size, at runtime.

View 1 Replies View RelatedI'm just getting started with developing for Android. I'm looking to port one of my iPhone applications, but I'm kind of at a loss for how to draw a view at runtime (a view not declared in the XML). Basically, I want to draw a simple rectangle, but then be able to manipulate its frame after being drawn. Sorry if this is a really, really simple question, but I can't seem to find some equivalent to the iPhone SDK here.

View 5 Replies View RelatedAs an additional anti-pirating strategy, I'd like to compute a checksum on my application at runtime. Since my app communicates with a back-end server, I can send the checksum with each message and the server can deny service to altered apps. Not a complete solution to piracy by any means, but a fairly easy way to raise the bar. Anyone know how an app can get access to it's load image at runtime?
View 15 Replies View RelatedIs it possible to load my main.xml layout file in onCreate() and then later in the app, switch to a new XML layout? I've tried placing setContentView() later on in the app but that seems to not actually set the new View because my references to objects in the newly set xml layout file are returning as null. I've tried doing some layout inflating using the LayoutInflater but I'm having no luck (I'm probably doing something wrong)... So is there any other way to swap layout xml layouts at runtime?
View 3 Replies View RelatedIs there a way to set a style for a View at runtime? I've seen this question a few times on the board here but no answers, so probably not:

iv.setStyle(R.style.myotherstyle);
Is it not possible to do something like this? We have to manually change everything in code instead?

View 8 Replies View RelatedI have a large (900kb) asset in the assets directory which is only used once by the app at initialization time. Is there way for me to delete this file at runtime? If not delete change it's contents to "0" and effectively reduce its size to almost nothing. There isn't really any point of having this take space on the phone's limited memory.
I am writing an application that will run on 2.0 and above. Now, I am thinking of adding the Data backup feature to the application.

View 1 Replies View RelatedI am developing an Android App which communicated with a server. User can select a language of his choice at startup or during the App execution lifetime. After selecting the language, the corresponding XML file is downloaded from server according to language which will map the "Values" of Application strings according to that language. Can I do something like replacing the default Strings.xml which contains English names(Say by default) to the language selected by user. Better will be adding an XML file per language and referring it runtime directly.
