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.

I'm trying to find a way to access private files created by other packages.According to the dev site (plz see the following), I can read/write files of other packages if some flags are set on the create of those files, but I don't know how. Can I just open those files with Context.openFileInput(or Context.openFileOutput)? Do I need a different way for those three cases? By three cases, I mean getSharedPreferences(String, int), openFileOutput(String, int), openOrCreateDatabase(String, int, SQLiteDatabase.CursorFactory).
View 5 Replies View RelatedBasically I want to know how to get a list or array or any type of data about the files that have been stored in an package specific data section. By this I mean that after using something like:
FileOutputStream fOut = c.openFileOutput(fileName, 0); OutputStreamWriter osw = new OutputStreamWriter(fOut);
How can I get a list of the files saved to the data location of my application where this file and other files or saved so that I can choose which file I wish to read or edit. I've searched and searched for this but have not found anything of use any help will be greatly appreciated.
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 RelatedI 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 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).

Is there any way of installing an app through any other means than clicking on the .apk file in the folder?

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've placed the subclass in a package called android.widget. Why can't I access any of the package-private member fields? I notice that the compiler says they "cannot be resolved," rather than not being accessible. Does this have something to do with how Android.jar is built?

If the phone contains SD card, it is clear that files should be saved there, but if there is no any external storage. where would you recommend to save to?
I wrote an app that downloads web sites and all their assets (images/stylesheets) to "disk" and therefore stores lots of small files on the SD card.
Sometimes it fails to delete large amounts of files and afterward the file system is r/o. To analyze that behavior I tried to do the removal of the files by hand and then go from there. But that already failed.

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).

It looks like file:///sdcard support was included in 2.1. The only reference I could find to it was at the end of this bug report thread.

I have installed the new SDK 1.6r1 on Windows and I realise that 1.6 does not included the older APIs so ran the android.bat tool to download them.
