Why am I getting this error when attempting to write to a database?
<p>I have this database code and the file where I want to write to the database. But when trying to find the database in the filexplorer there is no database. In logcat I'm getting this:</p>

<pre><code>02-04 21:16:02.722: INFO/Database(3361): sqlite returned: error code = 14, msg = cannot open file at source line 25467
02-04 21:16:02.722: ERROR/Database(3361): sqlite3_open_v2("/data/data/com.sr.android/databases/myapp", &amp;handle, 6, NULL) failed
</code></pre>

<p>Why don't I have any database? Where is the error?</p>
