Sometimes in LogCat I'll see Wrote stack trace to '/data/anr/traces.txt'
But when using the DDMS perspective, "File Explorer" View, I can't see anything in the "data" directory, I'm assuming because permission denied. Is there a way (short of rooting my ion device) to read what's in that text file?
Is there perhaps an android app for developers that will show the contents of the file? It would seem there would have to be some way of reading the file without rooting the device, otherwise why does the o.s. write it out? How can I read this file?
I want to download my apk file into "/data/local/" directory. I am able do this in external storage but unable on "/data/local" also i was trying to create folder on same location but could not do that. Through "adb push" it is possible but i need to do this java program.

System.out.println("DAta can write??--->"+Environment.getDataDirectory().canWrite());
System.out.println("DAta can read??--->"+Environment.getDataDirectory().canRead());
So please suggest me how to provide permission for the data directory.
What m trying to do is to create a file and add some content to it iin the Data storage of the emulator like as below
private void writeToSDCard() {
try {
File lroot = Environment.getDataDirectory();
if (lroot.canWrite()){
File lfile = new File(lroot, "samplefile.txt");
FileWriter lfilewriter = new FileWriter(lfile);
BufferedWriter lout = new BufferedWriter(lfilewriter);
lout.write("XXXXXXXXXXXXXXXXXX");
lout.close();
}
} catch (IOException e) {
Log.e(m_cTAG, "Could not write file " + e.getMessage());
}
}

Is there any way to read and process QR codes by manually? I mean that, I want to read QR code from my android software (not from QR code reader software) , then I want to get information behind the QR Code and than I want to connect and fetch some data from a database according to that information.
While developing such a android application, may I import QR code reader software jar file and can I access its api, if it is possible of course?
How do I create a shared directory with read/write permissions to all applications installed on my phone and that is not on the sdcard?

I've searched all over and cannot find a way to mark Read SMS text messages as Unread. I get lots of texts and sometimes don't want to address specific ones until later. On my BB and other phones, I could mark as Unread, so it would stand out later when I could deal with them. There doesn't seem to be an option in the initial menus for texts.

I try to create 'foo/bar.txt' in Android's /data/data/pkg/files directory.
It seems to be a contradiction in docs:
To write to a file, call Context.openFileOutput() with the name and path.
http://developer.android.com/guide/topics/data/data-storage.html#files
The name of the file to open; can not contain path separators.
[url]
And when I call
this.openFileOutput("foo/bar.txt", Context.MODE_PRIVATE);
exception is thrown:
java.lang.IllegalArgumentException: File foo/bar.txt contains a path separator
So how do I create file in subfolder?

View 1 Replies View RelatedI am trying to create a folder and several subdirectory within it on the SD Card... I then want to transfer files that I have stored in /res/raw to that folder...

View 1 Replies View RelatedI have a project written for Android devices. It generates a large number of files, each day. These are all text files and images. The app uses a database to reference these files.
The app is supposed to clear up these files after a little use (perhaps after a few days), but this process may or may not be working. This is not the subject of this question.
Due to a historic accident, the organization of the files are somewhat naive: everything is in the same directory; a .hidden directory which contains a zero byte .nomedia file to prevent the MediaScanner indexing it.
Today, I am seeing an error reported:
CODE:................
Regarding the sdcard, I see it has plenty of storage left, but counting
$ cd /Volumes/NO_NAME/.hidden
$ ls | wc -w
9058
Deleting a number of files seems to have allowed the file creation for today to proceed.
Regrettably, I did not try touching a new file to try and reproduce the error on a commandline; I also deleted several hundred files rather than a handful.
However, my question is: Are there hard limits on filesize or number of files in a directory?
am I even on the right track here?
Nota Bene: The SD card is as-is - i.e. I haven't formatted it, so I would guess it would be a FAT-* format.
The FAT-32 format has hard limits of filesize of 2GB (well above the filesizes I am dealing with) and a limit of number of files in the root directory. I am definitely not writing files in the root directory.
I wrote a file to the sdcard, but it failed as follow:String sdcardFIle = "/sdcard/xxx.txt" FileOutputStream fos = openFileOutput (sdcardFile, Context. MODE_ WORLD_ WRITABLE ) ; openFileOutput failed, because fIle "/sdcard/xxx.txt" contains a path seperator. It is so strange. Is there another way to handle the situation?

View 1 Replies View RelatedI am using following to code to create a directory
private static final String TRIAL_DIR_NME="trial";
File dir = getDir(TRIAL_DIR_NME, MODE_PRIVATE);
Now I want to create a custom file inside this directory. Basically I want to write "trial start date" for app and then compare that date to determine if trial period has expired.
Is it possible for the App to create a new file/asset and write this into the /assets directory. The reason being, that's the only way I can tell webkit will load a local file/resource.

View 2 Replies View RelatedI am new to Android and creating my first application.I want to create a file in the current directory. Basically I have a file bundled with aplication package as raw resource. I want to make a copy of this file in the current file. The reason to create copy in current directory is that I want my file reading code in native java, portable code.So my query is how can I create a file on current directory? The location current directory is important here as I do not want to make use of device specific hardcoded path or any Android API while reading the file. This is so I want my file reading code portable.

For my design i have in the xml file something like:
The design is like a row that have two cells. I want one of them to be autosize and fill the row and one of them to have fixez size. I want that the second linearlayout to wrapp its content and the first one to fill the rest of the space.
Something like in css having two divs floating left and one having fixed size and one filling the rest of the row.
Is something like that possible using the xml file without changing the sizes manually?

i am updating an app i developed so that it downloads xml files it needs for content management. the files download successfully to the emulator but are not placed in the /files directory that openFileInput() is attempting to read from. i am admittedly unsure as to the proper overall solution here - app originally used packaged XML and was fed to an XMLPullParser - but i cant even get as far as attempting to parse new XML at present because my app cant find the new file sitting in /data/data/[myApp]/ and not /data/data/ [myApp]/files and i cant figure out how to get it in there. the download doesnt work at all if i add that folder to path.e.
