    <p>I'm trying to overwrite a text file from android application, what I have done yet is,</p> <p>I have created one text file in one activity using:</p> <pre><code>FileOutputStream create_file = null; OutputStreamWriter osw = null; create_file = openFileOutput("filename.txt", Context.MODE_WORLD_WRITEABLE); osw = new OutputStreamWriter(create_file); osw.write("text goes here"); osw.close(); create_file.close(); </code></pre> <p>and I have opened that file in another activity read the contents line by line using:</p> <pre><code>FileInputStream open_file = openFileInput("filename.txt"); InputStreamReader isr = new InputStreamReader(open_file); BufferedReader inRd = new BufferedReader(isr); while ((getText = inRd.readLine()) != null) { Toast.makeText(getApplicationContext(), getText, Toast.LENGTH_SHORT).show(); } </code></pre> <p>through this I have verified whether the content is stored or not, and made sure that the file exist with the content, but when I try to overwrite that file from another activity using:</p> <pre><code>FileOutputStream create_file = null; OutputStreamWriter osw = null; create_file = new FileOutputStream(new File(PasswordUtil.pswrd_file), false); osw = new OutputStreamWriter(create_file); osw.write(getString); </code></pre> <p>I'm getting one exception,</p> <blockquote> <p><code>java.io.FileNotFoundException:/ filename.txt (Read-only file system)</code></p> </blockquote> <p>Note: The text file is stored in Internal storage.</p> <p>Any help, thanks in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
