Android : Way To Write To /assets Direcory / Save Arbitrary Files To It?
Jun 8, 2010
Is there a way to write to the /assets direcory and save arbitrary files to it? I am intending to download a HTML page which should be updated from time to time. If no network connection is available it should be taken out of the assets directory. I know I can reference fils in here using the file:///android_asset/ base URL, but can I write to it, too?

It seems that the Android resource compiler does not take into account linked folders (in Eclipse sense) in the assets folder. Question - is there a way to forcibly designate a folder of my choice as Android project assets? Short of copying or hardlinking into project assets, I mean.

I am working on an android app. Where i need to parse some plist files from assets folder. I do understand how to use assets in android but now problem is that file sizes are more than 1MB and so android gives error Data Exceeds UNCOMPRESS_DATA_MAX (2183588 vs 1048576). how to access such larger files from assets? Also I cant reduce a file into small buffers because i am just sending it to "DocumentBuilder.parse(in)" as a whole so can not use buffer. The error is on line: Document doc = db.parse(in).

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?

I'm going crazy, I created a file object, so it can be read with ObjectInputStream, and I placed the assets folder.
The method works with a file smaller than 1M, and give error with larger files.
I read that is a limit of Android platform, but I also know that can be "easily" avoided.
Those who have downloaded the game Reging Thunder, for example, can easily see that in their assets folder is a file 18.9M large.
This is my code ...
now I have an uncompressed file and I can use it without worrying about the error "This file can not be opened as a file descriptor; it is probably compressed"
This function works well with files smaller than 1M, with bigger files return an
java.io.IOException on line "ObjectInputStream ois=new ObjectInputStream(is);"
why?

I'm trying to save an object in a file but the file doesn't appear on the device and I don't get an exception either.
CODE:.....
If instead I use:
CODE:.....................
It works and I can see that the file has been created on the device.
But this isn't cool and it's not the way to do it because the directory structure may change in the future.

Can we assume that App can write to /sdcard some file? What can be reason one cannot do that? I could not find any documentation on sdcard rules in google docs.

I am writing a content provider to access data in a zip file. The plan is to extract data as needed to temporary files since the API Requires a file descriptor (as opposed to an input stream). The question is where can an Android app write files - we can assume these are small and regularly purged. I do not believe the /sdcard is required.

I 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 have an application that can read and write txt files to the phones sdcard. By using this code for reading files:
@Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); mFileNameOpen = files.get(position);
String st = null; mVector.clear();
notepad.mNewEmpty = false; try { File f = new File(Environment.getExternalStorageDirectory()+"/ notepad/"+mFileNameOpen); FileInputStream fileIS = new FileInputStream(f);
BufferedReader in = new BufferedReader(new InputStreamReader(fileIS));
do { st = in.readLine();
mVector.add(st);
}while(st!=null); in.close(); ...
} catch (FileNotFoundException e) { e.printStackTrace();
} catch (IOException e) e.printStackTrace();
and this to write them:
try { File root = Environment.getExternalStorageDirectory();
File fileCheck = new File(root, "/notepad/" + fileNameSave + saveExtension);
boolean exists = fileCheck.exists();
if (!exists) { if (root.canWrite()) { File textFile = new File(root, "/notepad/" + fileNameSave + saveExtension);
FileWriter textWriter = new FileWriter(textFile);
BufferedWriter out = new BufferedWriter(textWriter);
out.write(SAVEAS); out.close(); written = true;
} else { written = false; else { written = true; showMaybe = 1; showDialog(DIALOG_SAVE_EXISTS);
catch (IOException e) {Log.v(getString(R.string.app_name), e.getMessage());
This has been working fine on my Tattoo and all the emulators I've tried this on. But it does not seem to be working on moto droid. Is there something different to consider with moto droid? Or have I missed something in the manifest maybe?

I'd like to know if there's a way to write files into the main directory just before the system shutdown, something like this:
End all processes (-> unmount disks?) -> mount /sdcard rw and / rw -> copy files from /sdcard to / -> unmount disks -> shutdown/reboot
Same with boot image (flash, in this case, and not copy / mod files)... is it possible? Or do I require to boot into recovery for these operations? I know I can remount as rw my system directory via ADB
Also, is it possible to do the same thing with the build.prop file? This, or during startup (before mounting partitions with standard permissions).
Of course, this having root (but not a special kernel to enable this kind of "before mounting" thing).

I have tried to update my Honor C3 system updates. Then I noticed that I have completely lost root access. They removed su binary. Then I tried to root again my Honor C3 with VROOT and it is OK again. But I can't overwrite system files such as changing system DroidSans-fallback.ttf fonts and also installing framework of Xposed (Overwriting app_process). I can't even delete system files also.
I searched for firmware files for my phone and I can't seems to find it. There is root access and I even test it via Terminal Emulator app and from ADB. Calling su binary in Shell was OK but I can't access /system well. H30-U10

"Every Android-compatible device supports a shared "external storage" that you can use to save files. This can be a removable storage media (such as an SD card) or an internal (non-removable) storage. Files saved to the external storage are world-readable and can be modified by the user when they enable USB mass storage to transfer files on a computer." PROBLEM: I cannot write to a file on the sdcard. QUESTION: Is it possible to write to a file on the sdcard?
If YES, what do I need to do to make File.canWrite = true? I am using Android 2.1 update 1, API level 7, Eclipse, and HVGA skin. I am running my app / troubleshooting on the Android SDK ADV. When the AVD is running, I check settings > sdcard total 49.21MB, available 49.07MB................

I'm trying to build an android application that features a graphical display drawn within a RelativeLayout. I want to place "+" and "-" buttons next to several of the parameters, which are drawn at various points on the canvas. The positions are free-form don't seem to conform to any of the standard XML layouts.I know how to create the buttons programmatically, but I don't know how to place them over the canvas where I need them to be. I'm assuming that this would be done in the view thread's doDraw() method, after all the graphics have been drawn, but how?

I'm saving files in
sdcard/Android/data/<packagename>/files
the problem is that everytime i download the app to the phone - the folder and it's contents get deleted.
anyway to prevent that.
ideally i would want that to happen only when the user uninstalls.
for debugging and user app upgrades - i'd like the folder and it's contents to remain.

I believe I know the basics and have successfully published a nice graphical game (Tairu). I know about inflating an xml layout and instantiating views that work.
For my current project, I really just want something similar to the Windows 'DrawText' function where it will draw a bit of a text inside an arbitrary rectangle of the surface, and do word wrap within that rectangles boundaries. That's what I really WANT, but I can't find any form of drawText that will wrap.
So, while that's what I WANT, I can accept the thought of programmatically instantiating a TextView (which wraps beautifully). But I still need to be able to provide the rectangle, which is highly dynamic. (which is why I want to call a form of drawText inside of my onDraw method). In this particular case, I have something which is static to a particular view instance (I mean, the View becomes visible, the position is set, and does not change after that. but the text position is dependent on game state and cannot be pre-determined inside an XML layout). So in this one case, I could afford the expense of runtime recalculation of the layout when the view is displayed.
OK, fine. So I do something like this:
CODE:......
Pretend you didn't see 'AbsoluteLayout' there, I am desperate and have tried all possible layout classes
main_frame is defined in my main XML layout (it is the outermost layout, fills the parent, and, as I said, I've tried all the offered layouts)
With this code, the textView appears, but along the top of the layout, and not using the width I provided either.
Adding, out of desperation.
CODE:.......
makes no difference. In fact, so far, NOTHING has made any difference. So I thought, ok, while this seems like a useful thing to be able to do, I can accept if it can't. I accept that it is impossible to provide dimensions in advance and that you have to override the measure and layout callbacks then requestLayout and in your overrides, force the final layout for the TextView.
Of course, that is completely unacceptable for my FIRST desire (a drawText that wraps to a rectangle, called from onDraw as needed). But the point is I feel something like that OUGHT to work, and it doesn't, so clearly this is MY fault.
Getting back to what I WANT, I guess I can do it myself by repeated calls to measure text and parsing the string for spaces until I get the N characters which fit on the first line, then repeat for additional lines, calling a normal drawText for each line (and using textMetrics to determine the vertical offset to the next line.)
But why wouldn't that method already exist? I promise not to fill the screen with a zillion calls, and/or to cache pre-rendered text on some bitmap somewhere if antialiased drawText is too expensive to repeat frequently.
