Android :: Need To Read Trace - Text File /no Data Directory
Sep 25, 2009
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?

Do anyone have a file in the root directory of your SD card named search.trace? I have one that is about 8.5 megs. I took a look at it but it didn't look like the entries were specific to a particular app. Looks like some system log. Anyone know if there would be a problem deleting it?

I m using Android 1.5 my data directory does'nt have the read/write permissions
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());
}
}

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?

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.

I am creating an application for the android, and would like it to be able to read a text file via anonymous FTP. I've tried URLConnection, but it doesn't seam to be working. After some Google searching it appears that URLConnection doesn't always work with some FTP servers. All of the java FTP connection libraries I've found require you to download the file to a local location before reading it. However I would like to have the same functionality as URLConnection in that I can just use the following similar code...

I am trying to read a file "words.txt" from a resource. It is a very simple, but large (2 MB), text file that I want to read line by line. I have put the file into /res/raw/words.txt, and try to open it with the following code:
CODE:...................
However, I get a java.io.IOException. This is not a "resource not found" exception, so the resource is opened correctly, but the readLine() produces the error.
I tried using the InputStream itself, with the result that read() produces -1, which stands for EOF, as if the file was empty.

I have a text file added as a raw resource. The text file contains text like:
a) IF APPLICABLE LAW REQUIRES ANY WARRANTIES WITH RESPECT TO THE SOFTWARE, ALL SUCH WARRANTIES ARE LIMITED IN DURATION TO NINETY (90) DAYS FROM THE DATE OF DELIVERY.
b) NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY VIRTUAL ORIENTEERING, ITS DEALERS, DISTRIBUTORS, AGENTS OR EMPLOYEES SHALL CREATE A WARRANTY OR IN ANY WAY INCREASE THE SCOPE OF ANY WARRANTY PROVIDED HEREIN.
c) (USA only) SOME STATES DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO THE ABOVE EXCLUSION MAY
NOT APPLY TO YOU. THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS AND YOU MAY ALSO HAVE OTHER LEGAL RIGHTS THAT VARY FROM STATE TO STATE.

I have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format:
1|a|This is line 1a
1|b|This is line 1b
2|a|This is line 2a
2|b|This is line 2b
2|c|This is line 2c
What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.
a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line.
b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value
<!--sample XML -->
<data>
<line number="1">
<entry name="a">This is line 1 a</entry>
</line>
</data>
c.) Should I just copy & paste the whole file as a static string array in the application and use that.
[EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".
