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.

View 14 Replies View Related1)Where can you place shell scripts you write for yourself? I tried placing them on the sdcard but they won't run from there. I tried placing them in /mnt/emmc but same problem. I tried making a /bin folder in the root directory but it gets erased when I reboot the phone.
2)Is there a way to edit my PATH to include this location. Normally I would put it in .profile or .bashrc in my home directory but there doesn't seem to be a home for the phone that I can tell when I access terminal emulator. root doesn't seem to have a HOME variable set either. How can I modify my environment?
3)Can you create a new user with specific permissions? I would like to create a user and have a folder that is only readable by that user on the phone. Maybe, not sure if this will work with apps etc.
4)Can bash be installed?
5)Can perl be installed?
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:

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.
View 6 Replies View RelatedHow to write/read log data into txt file in res folder.
View 4 Replies View RelatedI 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());

View 1 Replies View RelatedI'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

The error from LogCat: E/PackageInstallationReceiver( 244): Remove /data/local/tmp/my.package.apk Fail! W/System.err( 244): java.io.IOException: Error running exec().
I used adb shell to see whats inside this tmp folder. And there was no such apk. So I renamed another, but the error stays which means, that he never really tries to delete this apk, right? The same code runs fine on the emulator and my Nexus One.
For an example of what I'm looking for, hit the Home button while you're composing a message in the Gmail app. A little message will pop up at the bottom of the screen for a moment that says "Message saved as Draft."

View 1 Replies View RelatedI'm currently trying to create a buffer for my application which needs to be big!I mean at least 1MB but most likely to be 4MB.Now definitely bad idea to actually allocate this much on a byte array in memory.So the options are put all the data in a file. So question is where do I place this temp file?
Option 1: Store to sdcard. Might be slow and not such a good idea for continuous read/writes?
Option 2: Store to in the apps cache.I read somewhere this is fast for read/ writes. But also read before issues cleaning up the cache after use? I guess I should as if I be able to create a file in cache and discard it when I don't need it? Any tips/look outs from using this methods would be greatly appreciated!
I run Android SDK and AVD Manager in Vista and have problems installing components. The installer downloads components successfully, but at the end of the installation it hangs for about minute and then asks to disable AV software. If I choose 'No', the installer stops with error message like: "Filed to rename directory '...' to '...' ". Thus, I have to unpack downloaded components and place them to proper folders manually. I have no AV software.
View 1 Replies View RelatedI have a programmatically generated image that I want to send as an attachment via the ACTION_SEND and EXTRA_STREAM method. But how do i do this? My first attempt (writing to my context.getCacheDir() based file path) appeared to work in the Gmail preview (no image preview, but attached file name and icon was visible), but the attachment never arrived on the recipient side. I guess this has something to do with permissions on the generated file, but how to avoid this? Do I need to set more permissive settings on these generated files (so that the Gmail activity can access)? Is that even possible for the app's cache folder?
Is there another file location that would be more suitable to write my files to? I considered the downloads folder, but think it would be an awkward location for something that only needs to exist until it has been emailed. I have even tried encoding my image purely in a data:image/png;base64,ABCD... style URI. This, too, showed up in Gmail preview (attachment icon, but no file name), but did not result in a recipient-side attachment. Has anyone been able to attach a one-shot generated image to an email intent by any means? What options may I have overlooked?
