I 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.

1) 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...

In this case 'i' is -1 meaning nothing read. Why would nothing be there if the file is there, the variable 'files' has the file as well. Do I need to do anything to the file I put into the Assets folder in get it to be readable? When I use a small text file it works. When I use a 10 meg file, it does not. (The 10 meg is a Sqlite database I need to install)

View 2 Replies View RelatedIt has come to my attention that Android can only deal with asset files that are around 1M or so. My problem is that i'm creating an app that requires access to 5 csv files. The largest of the files is 130M. I want to be able to package these text files with my app. Is there anyway around this? My app needs to be able to run without Internet access so storing these files on a server is not an option.

View 1 Replies View RelatedThe instructions for my app are in HTML format in my assets so I can display them with proper formatting and hyperlinks in a WebView.

View 2 Replies View RelatedI would like to install an APK from within an Android application. Can anyone give me an example of how to do this? Also how do I open the install applications from unknown resources preference page so that users can change it? I actually meant open the screen using code, so I can immediately open the preference page for the user to simply check the box, and press back. Is it possible to check to see if they allow non-market apps? Can an application request permission enough to do this?

I'm loading html into a webview from my assets folder, works no problem. In my second experiment I've loaded HTML from a database (after pulling from remote source) and displayed in a webview (also no prob). Now I'm trying to change the baseref inside the html to have all JS and CSS references point to source files under assets. This part doesn't seem to work. I get warnings from the web console that it can't load these files due to security issue.
Now I've resorted back to a content provider and overriding openFile (and setting base ref with content://...) but now I'm hitting another problem with the JS and CSS files in assets being compressed. Can load html from assets but loading JS, CSS from within that HTML is another story. Before I dig deeper, am I over-complicating this?
What is the absolute path of the assets folder? I need it to reference some images saved in this folder from a html file saved in the memory device.

View 1 Replies View RelatedI'm developing an Android game that has to download some assets to the SD card to keep the size of the app as small as possible. I was thinking of using an uncompressed zip file to bundle all the assets.
A requirement from the client is to protect these assets as much as possible. Being part of the apk is considered enough protection, but if I do this the apk size will be enormous. If I just put a zip bundle in the SD card, then anyone can unzip it and explore its contents.
Is there a simple way to do this without retorting to horrid DRM?
I have 5 mp3 files stored on the assets folder. The files are all 25 KB. I load the files using:
manager = context.getAssets();
this.inputStream = manager.openFd(fileName).createInputStream();
Whenever I try to play the files, the sounds are all messed up like they were mixed or something.
I've zip aligned the app already but with no results.
I have a WebView that I'm using to display some html/image files stored in the assets/ directory.
View 10 Replies View RelatedWhat I am trying to do is simply copy over entire folder full of mp3 files onto sdcard within an app. I am doing this out of "assets" folder because raw folder does not allow mp3 files to be named the way I need them to. Here is what I dug up so far but not sure if this will work. I am lost.
InputStream ins = getResources().getAssets().open(""); int size = ins.available();
// Read the entire resource into a local byte buffer. byte[] buffer = new byte[size];
ins.read(buffer); ins.close(); FileOutputStream fos = new FileOutputStream("/sdcard/myfolder/");
fos.write(buffer); fos.close();
I want to change the font in my widget such that it uses a specific font in "assets" folder of my app. I usually do this in my app to change the font:
Typeface tf= Typeface.createFromAsset(getAssets(), "advertising.ttf");
TextView converted = (TextView)findViewById(R.id.TextView03);
converted.setTypeFace(tf);
And it works like a charm. How can I do this in widgets? I can only set the text and change the color:
remoteView.setTextViewText(R.id.TextView03,"some text" );
remoteView.setTextColor(R.id.TextView03, Color.BLACK);
But I don't see a way to set the font.
I was poking around in the documentation for the simpleCursorAdapter and I read that if the simpleCursorAdapter doesn't identify your images as resources it will assume they are URIs. My question is how do i retrieve the URI for an image placed into the asset folder of my application?

View 2 Replies View RelatedI my main app and tests are organized like this (standard from "android create project"): AndroidManifest.xml assets/ main app asset files src/tests/AndroidManifest.xml -- uses <instrumentation> to point to the main app assets/ -- test-specific asset files src/ Writing test cases with AndroidTestCase, I'd like to load asset files from the test-specific assets/ directory, not from the main app assets/ directory. How can I accomplish that? The normal way to load an asset would be getContext().getAssets().open ("foo.txt"), for assets/foo.txt in the main app. I assume I just have to somehow change the Context or the AssetManager to point to the test- specific assets directory, but I don't see any way to do that. I have looked into the tests/bin/MyApp-debug.apk to confirm that the test assets are in there. Now I just need a way to access them.

I am creating a simple android app to view a comic book. The pages are large(0.5-1 mb each), high quality .png's and I am loading them into a webview to make use of the built in zoom controls. So far I only have 17 files and the APK size is already about 16 mb. I'm looking to add over 200 files in future updates. I can't really reduce the quality too much because there is small text that must be zoomed-in on to read. Any suggestions? A similar question was posted here: How to reduce App (.apk) Size, but I don't want to lose the quality of the images. I'm not sure if it's appropriate to link to here, but you can have a look at my app by searching for Tracer (by Detour Mobile) on the android market if it helps at all.

View 4 Replies View Relatedmy application caches static resources in its /assets directory and implements a content provider to provide them to a WebView on request. i kinda have to drive around the houses a bit because it seems i can't get a linear file descriptor on an asset, i get "this resource is zipped" or somesuch, don't know why that's a problem. the content provider just caches the asset in /sdcard and then returns a file descriptor off that. this has been mostly working fine, but i've started seeing errors from the PackageManager. nothing's changed on my end, the assets are still there, etc. the actual error i'm getting is -ndroid.content.pm.PackageManager$NameNotFoundException: ComponentInfo{package/activity} (where "package" is the name of the package, etc) can i get anything wrong with this stuff? caching javascript and css stuff in the apk has been a big performance win.
