    <p>You can do this with the Android <a href="http://developer.android.com/reference/android/content/SharedPreferences.html" rel="nofollow">SharedPreferences</a> Class which is a which way to save setting between launches.</p> <pre><code>SharedPreferences appSettings = this.getSharedPreferences("fileName", 0); SharedPreferences.Editor = appSettings.edit; appSettings_Edit.putString("saveme", "this will be saved"); //First Parameter, name of the value, second parameter, value of the name appSettings_Edit.commit(); //This is called to commit the changes to memory. //This can be called anytime after `commit()`, including in any sequential launches, and it will return the vale of whatever you set. appSettings.getString("saveme"); </code></pre> <p>If you want to save an actual <code>file</code> you can use a BufferedWriter to create some hard file on the system:</p> <pre><code>BufferedWriter out = new BufferedWriter(new FileWriter(new File(fileName))); out.write("I am a line of text written in" + fileName); out.close(); </code></pre> <p>You can then retrieve the contents of the file by using a BufferedReader:</p> <pre><code>List&lt;String&gt; SomeStringListArray = new ArrayList&lt;String&gt;(); BufferedReader in = new BufferedReader(new FileReader(new File(fileName))); String s; while ((s = in.readLine()) != null) { SomeStringListArray.add(s); } in.close(); </code></pre> <p>You can also create this file in the Android Cache Directory so it will be accessable only by your file by having the path of the file name derived from:</p> <pre><code>this.getChachDir(); this.getExternalCacheDir(); </code></pre>

    1. COThe use of BufferedWriter seems like a good idea... Is there any limit on how the big the fie can be, or does that depend on the available memory allowed for the app? I'm thinking the data could reach sizes of 10+ megabytes.

    2. COI myself have not run into any problems with file size, however you will get to a point where it will take a long time to process depending on the file size and processing speed. I am not exactly sure if there s a file size limit. See my edit for retrieving data from the file.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
