Can't find created file

Question

I'm writing my little app for Android. I'm trying to create files. Here is a code snippet:

final String TESTSTRING = new String("Hello Android");                 
FileOutputStream fOut = openFileOutput("samplefile.txt",Context.MODE_WORLD_READABLE);
OutputStreamWriter osw = new OutputStreamWriter(fOut); 
osw.write(TESTSTRING);
osw.flush();
osw.close();

FileInputStream fIn = openFileInput("samplefile.txt");
InputStreamReader isr = new InputStreamReader(fIn);
char[] inputBuffer = new char[TESTSTRING.length()];

isr.read(inputBuffer);

String readString = new String(inputBuffer);

boolean isTheSame = TESTSTRING.equals(readString);

if(isTheSame) {
    TextView mLat=(TextView) findViewById(R.id.textView1);
    mLat.setText(String.valueOf(isTheSame));     
}

I can't find this created samplefile.txt using file manager. Can anyone tell me the path where app is writing?

ok now i have this:

String pathToExternalStorage = Environment.getExternalStorageDirectory().toString();
     File appDirectory = new File(pathToExternalStorage + "/" + "testowa", "new_file.txt");
     try{
         OutputStream os = new FileOutputStream(appDirectory);
         os.write(pathToExternalStorage.getBytes());
         os.flush();
         os.close();
     }
     catch(IOException e)
     {

     }

Exception Thrown on OutputStream os = new FileOutputStream(appDirectory); Cant find why. i modified manifest with permissions

The file is located in /data/data/com.yourpackagename/files/filename.txt which is hidden unless the device is rooted. You can access the file by copying it from the directory where it is created.

From the command line:

To copy a file

    adb -d shell 
    run-as com.yourpackagename 
    cat /data/data/com.yourpackagename/files/filename.txt > /sdcard/filename.txt

Alternatively for a SQLite database

    cat /data/data/com.yourpackagename/databases/dbname.db > /sdcard/dbname.sqlite

This solution will work without having to root the device.

You can get the path of the files created using openFileOutput(name) using getFileStreamPath(name). But file manager apps will need root privileges to view this path.

It is created in /data/data/your.package.name/files. However, this directory is not visible for file mangagers (unless they have root rights).

So if i want files to be visible for users, I will need to use external drive? – szpic Dec 25 '12 at 14:00
Yes, have a look at `Environment.getExternalStoragePublicDirectory`, it returns the directory where you can put the externally visible files. – Henry Dec 25 '12 at 14:13
