Android :: Why I Can't Find .db File In Data Directory Of My Application?
Aug 21, 2009
I have written a test case to implement a conference contact management system with Content Provider and SQLite. The launch activity is a Listactivity and the customized provider is extended from ContentProvider, u know, actually the sample is so similar to the Notepad Sample in the official SDK packages. However, i can't find the created .db file in the /data/data/myapp/ except the /lib directory. Why?

Is there a preferred way to find the data directory of an application, other than starting with android.os.Environment.getDataDirectory() and appending "/data/" and the package name?

I am using ZipInputStream and BufferedOutputStream to decompress a file from a zip archive in Android 1.6. The code runs without exceptions, but when I check the existance of the file, I can't find it. I am just looking for the filename. Is there an application directory that stores this file? Do I need to specify a directory?

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 have an Android app that saves a text file directly onto the phone, in the app's install directory. I need to allow the user to create a new email, attaching this saved text file. When I start the intent to send the email, everything shows up in Gmail correctly, but the attachment does not get sent. All of my searches on stack overflow seem to only deal with attaching an image file from the SD card. Below is the code that I used. Please let me know if I have done something incorrectly.
File myFile = new File(getFilesDir() + "/" + "someFile.txt");
FileOutputStream stream = null;
if( file != null )
steam = openFileOutput("someFile.txt", Context.MODE_WORLD_READABLE);
stream.write(some_data);
Uri uri = Uri.fromFile(myFile);
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/plain");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
sendIntent.putExtra(Intent.EXTRA_TEXT, email_text);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
file.close();
startActivity(Intent.createChooser(sendIntent, "Email:"));
I've also tried sendIntent.setType("application/octet-stream"); but that didn't make a difference. I'm at a loss for why the file doesn't attach and get sent.

how to find permissions a given application has. Each app is run as a certain user, so wouldn't finding the file permissions of an app be the same as finding the file permissions of a user? On Linux/Unix there is the find command but I don't know of any alternative command that is available on android. I am running KitKat 4.4.2 kernal 3.40-gadb2201.

I plan to bundle an xml data file that has all the metadata required by the application. When my app loads for the first time, the xml data file is read and local database is created and populated. This xml file is a crucial part of my app and it holds at least 100k entries. I don't want this data to be compromised.
Is there a way to encrypt this data file so that the file is unreadable in case someone opens the .apk file and extracts the data file.

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?

I 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.

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?

This should be very simple, but I can't find the answer anywhere. How do I load an html file (which I assume I keep in res/raw folder) into a webview?
neither mWebView.loadUrl("file:///raw/about");
or
mWebView.loadUrl("file:///raw/about.htmal");
works.
What's the correct syntax or arrangement.

when I run this code, it starts playing all the audio files in the assets directory, in alphabetical order instead of just playing the audio file I requested. What am I doing wrong? Is there a better way to play audio files from the assets directory?Is there a difference between keeping audio files in the assets directory and keeping them in the res/raw directory? Besides the fact that they don't get ids if they are in the assets directory. If I move the audio files to the res/raw folder then I have a problem with reusing MediaPlayers because there is no id parameter for setDataSource(). I can't find a good guideline for handling this kind of problem.

Is there any way that I can link a keyword in a TextView to a file or directory on the user's SD card? My app produces stack trace files when it crashes and I want the user to able to click a link in my About dialog to view either the latest one or the folder containing all of them. (Something like "If this app crashes, please send [link]the latest stack.trace file[/link] to us at myapp@example.com.")
