Android :: Loading Entire Asset Folder
Jan 2, 2010
I have been trying to figure this out for some time now. Is there any way to load the entire Assets folder instead of having to code it for every single item? Also, once the images are read, is there a way to have another app (already installed on the device) grab that data? The intent is declared in the manifest and on it's own with the items in the res/ drawable it works fine but to have more then one option I'm using the assets folder with subdirectories. The user choses an option, that directory loads through another app already installed, if that makes sense.

What 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();

So my app downloads images at the users' request from an online source. Through a button in the activity, the user can choose to hide or show the images in the gallery. This is easy enough, I just add or remove a .nomedia file as needed. However, I want to rescan media every time so that the change is instant, and requires no further user interaction.
After each image is downloaded, I am using the method at http://www.mail-archive.com/android-developers@googlegroups.com/msg24164.html to scan the specific image into the library. That works great for one image, but when the .nomedia file is added, I really need to be able to scan a whole directory.
I have considered calling the MediaScannerNotifier on each image in the directory, but that just seems clumsy and lazy.

I recently rebuilt my project to target 2.2 from 2.1. In the old project, I did not specify a target SDK (the manifest did not contain something like:
<uses-sdk android:minSdkVersion="8" />).
This gave me an error in the console when running, but everything worked fine so I didn't fool with it.
The new project now uses <uses-sdk android:minSdkVersion="8" /> in the manifest. But now my drawables from the /drawable-nodpi/ folder are loading with scaling, making them much smaller and significantly changing the desired visuals. If I cut out the <uses-sdk android:minSdkVersion="8" /> tag from my manifest, they load properly without scaling.
Even when loading my images like so:
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inScaled = false; Bitmap bm = BitmapFactory.decodeResource(_resources, resId, opts);
They are still scaled when I declare the minimum SDK in the manifest, but not scaled if I remove that tag. How can I load them without scaling while still declaring the minimum SDK?

From digging around a bit, getAssets() is an inherited method from ContextWrapper. It returns an AssetManager, and using open() it can return an InputStream. What I'm attempting to do at this point, is use the GLSurfuceViewActivity, Cube and CubeRenderer to work and learn off of and read in vertex data from a binary file. I've already created the binary output by parsing a model obj file and added to the assets directory. My Shape class (modified from the Cube class) does not have access to calling getAssets() since it's not a subclass of Activity or ContextWrapper. Once I accepted that, I tried to think of the best way to read in the data (without storing it extra places) to the Shape class. What I did, and seems to be working okay, was modify the Shape and ShapeRenderer constructors to accept an AssetManger as a parameter.

I want to display a fancy 'loading' image at my app's startup time.
The problem: my startup code is mostly GUI related, hence needs to run on UI thread.
Is there a way to do both - that is run UI-related code on UI thread while an image is displayed to the user?

I'm placing the file '.nomedia' into a folder in order to avoid Android's MediaScanner from detecting the media files in the folder. I need to copy this folder (including '.nomedia') from the APK's assets to the SD card (so other apps can make use of these media files, etc.). When I package the APK in Eclipse, it doesn't package the '.nomedia' file. Presumably it's detecting it as a hidden file. Any ideas how to fix this? Is there a secret aapt flag I can use? I'd like to avoid copying the folder and then manually creating a '.nomedia' folder, if possible.

I need to be able to be able to call readAsset from outside of the main activity of my application. I have heard people mention needing to pass the Context around, but the language has been very vague. Can someone describe the steps necessary to add the ability to call readAsset to an existing class that is not the main activity? Creating a public function in the main activity and having others call that will not work as the place I need to add readAsset to, is in a separate thread.

I am creating a game using the irrlicht c++ 3D graphics engine port to android platform. The graphics engine is written in c++. I need to be able to load meshes and textures etc from c++ code. My current plan is to place all the game asset files in either the res/raw directory or the assets directory then on start-up copy these files to the sdcard so they are accessible from the irrlicht c++ code.Is this the best way to make the game media files accessible from c++?

I am trying to download a zipped file from the web on the first instance of the application; can someone point me to a tutorial for this (I don't see good documentation on developer.android)? I understand how to check if it's the initial start or not, and also how to use java.util.zip once I get the file, but it's the in-between where I'm lost.

I'm trying to load/reference images from the app's assets folder from within a HTML page in a WebView. Unlike in most of the examples the HTML page itself is not located in the assets folder but is loaded from a server via http. The background of this question are some performance improvements which should reduce the loading time (and the amount of transferred data) by loading static images directly from the device. I'm not sure if Android has some restrictions here because there's a certain possibility to exploit the app by allowing access to the local file storage from a remotely loaded webpage.

I've tried looking around google, xda search tool, have read all pages (3 of them) in Xposed wiki. I've been trying to cheat in a game called Galaxy On Fire 2 HD (I have purchased it), I've found some tutorials how to do that on iOS by modifying some binary files (assetsdatainships.bin and items.bin), on android those files are in game apk, and I cannot modify them without breaking signature.
I found Xposed framework and I think it could be perfect for my purposes. Is there an easy way to replace those asset files by my own? I have very little programming skills though, but I'll try. I've found a short example in wiki, but I don't understand it. I've read wiki tutorial 2 times but still have only vague idea how all this works.

I've looked through the documentation and I can't seem to figure out how to have the screen blured/greyed when I select an activity that may take a while to load.
This seems to be an Android standard (both the Camera app and the Camcorder app do it when first selected), but I don't see any documentation on it. I even tried looking through the source of these apps on git, but couldn't seem to find it.

I can't seem to rotate properly an image on the entire screen. The problem is that when the image rotates, you can see the background in some areas. I want the image to fill the screen also when it rotates. Here is the layout.I start the animation in onResume. As I said, the image rotates but there are background areas when it does rotate. I've tried using images much bigger than the screen but still it doesn't do what I want. I don't care that outer regions of the image are not visible. I just want the rotation to fill the screen. I guess ImageView sets its width and height initially and then, when it rotates, it uses those dimensions. Is there a better way to do this?
