Android :: Access Larger Files - More Than 1 Mb Plist Files - From Assets Folder
Nov 4, 2010
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 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 want to access files in the /sys, to be exact in the /sys/class folder. I just need to read some values there. I tried the Context.openFileInput method, but got only exceptions and I understand this is not the right way.

I have lost a few pdfs which I have been reading for weeks (!) on my Nexus 7 (Android 4.3). Via the reading history of my pdf reader (Moon+ reader) I can see that at least one file is still present in the cache under the following folder address: /data/data/com.google.android.apps.docs/cache/filecache2/c042587322c4a438463efbd2cc533cbf/mypdf1.pdf
How can I access this folder? When accessing the device via the Android File Transfer sofware for Mac, I don't see this folder. I have access to Android/data/com.google.android.apps.docs/files, but this folder contains no files but only another folder (called "pinned_doc_files_not_for_edit") which is also empty.
The lost pdf is still there, I can open it in the reader via the reading history, but I would like to access the folder to see whether other lost files (which are not in the reading history) are also still present. To be clear, the file which I can open is also not detected when searching the device for pdfs.

I uploaded about 50 pictures from iPhoto (using a Mac) just to see what they looked like and then later formatted the Droid's SD card, so the pictures were no longer there.
Now, if I mount the Droid via USB and view the file structure there is a folder named /albumthumbs which contains 50 files, presumably for the 50 pictures a had on the SD card.
To me, these file, unless linking to actual photos stored on the SD card, take up extra space in the phone's memory (not worried about the SD card). I wonder if I can safely delete them (just the files...not the folder)?

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?

When I'm trying to transfer music files or whatever to my x10 mini pro via USB, files larger than 2.5Mb get completely hung up, crashing both my phone and my computer (this happens on my work desktop and my laptop at home, win7 and winXP). I have to disconnect the cable and take out the battery and restart my phone in order to fix it. Smaller files go quickly and without issue, which leads me to believe it's not an issue with the usb cable (I've tried a few different ones also). Also, if I transfer files to the SDcard directly using a card reader, it's no problem. This is super frustrating since it means I have to take the back off the phone and take the card out to move music around, and it's something I do pretty often.

I' m clicking on a download link on a website for a file that is 200 MB. The file starts to download then says complete, but only 19.71 MB is downloaded. Is there an app or browser setting which may prevent or cap file downloads directly from a web page and NOT from a store app?
I'm on an AT$T Optimus Pro running Ice Cream Sandwich

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 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.

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'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've thought of starting to develop an application and one of its features is that it downloads some content (images, files, etc) and organize them into folders in accordance with site they were downloaded.
Well, the question is... How do Android organize your files? In Windows, for example, I could create some folders, one for each site, or one for each time period. But in Android, how does it work? Is there a system of folders like Windows? Or is there a totally different way to organize files?

I just noticed that there are some duplicate entries in my /data/app-asec folder. Some even with different sizes, e.g.:
com.dama.papercamera-1.asec (21.3 MB)
com.dama.papercamera-2.asec (18.3 MB)
Where's My Water is also there with 2 files, each consuming almost 60 MB. It looks like I could delete one of them. But why are there duplicates in the first place? And why doesn't Android cleanup this mess itself?

I'm trying to use the library RootTools to make root operations on android system. I want to make a backup of some files including in the /etc folder with the next commands:
Code:
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
File exists = new File("/etc/gps.conf");
if (exists.exists()) {
[Code] ....
It's supposed that with the RootTools.copyFile I can make that operation, but It doesn't make anything. I see that in cat /proc/mount doesn't appear etc folder. I'm tried too with the Apache transfer file copy, FileUtils.copyFile(source, destination) but it seems that it have problem with the mount system, who seems to be in RO. I try too with RootTools.remount("/etc", "RW") but fails too.
I want to know how I can edit, create, delete, modify files in /etc /data... etc.
I'm testing this on a Samsung Galaxy S3 with an stock rom 4.1.2.
