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.

How to change the size of LinearLayout when it is runtime ? I've set the size dynamically when it is runtime. But no luck. Didn't change the size of LinearLayout.
View 1 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...
So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
View 1 Replies View RelatedI am currently developing a dictionary application with voice database. I would like to know about the current Android limitation on the file size. I am using a self-provided sqlite database ( > 50mb ) . I tested that once the built .apk size exceeds ~30mb the app will not be installed onto the simulator (INSTALL_FAILED_ INSUFFICIENT _STORAGE). Could anyone confirm me that if up until now there is no way to embed such large size files in a single apk ( Aimed to sell at Google Market without requiring user to download datafile afterwards). Also, is there a limitation of 1,048,576 bytes for a single file in the assets folder ?

I manage a cache of bitmap. Do you have an advise to fix the maximum size of it?
View 2 Replies View RelatedCan somebody explain to me what makes up the installed application size? I have an apk that is about 8 MB, and often when I install I get the INSUFFICIENT_STORAGE error. I have around 25-30 MB free space on the phone. I'm doing debugging so I have to upload lots of new versions. If I uninstall the previous version then I can install the new version. The application manager claims that the app is taking up 22 MB. So back to the original question, how come the app is taking up 22 MB when it really only is 8 MB?
View 7 Replies View RelatedI would like to know why the size of my shared library .so is bigger than my .apk file generated with Eclipse? Approximatly the so size is twice the apk one. What is strange is after having installed it in the device (2.1 firmware) I checked the size of the apk when I uninstalled it from the device and surprisingly the apk size indicated is bigger even than the .so one. Is there any explaination of that?
View 2 Replies View RelatedMy app downloads .png files to the sd card for later use. I kept getting OutOfMemoryErrors (if anyone could explain this too, that'd be great!) and so I took a look at the sizes of the images saved to the sd card, and they seem to be roughly double what they are on the server. Why is this, and how can I make them smaller?

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?
