    <p>If you're actually more interested in learning to write your own, I'd suggest taking a good long read through the <a href="http://developer.android.com/reference/java/io/File.html" rel="noreferrer">File</a> class documentation. That's where you're going to be doing most of the work.</p> <p>In the case of SD cards/other external storage for Android, you'll want to first check to ensure that the external storage is mounted and available before trying to read it, using the <a href="http://developer.android.com/reference/android/os/Environment.html" rel="noreferrer">Environment</a> class:</p> <pre><code>String extState = Environment.getExternalStorageState(); //you may also want to add (...|| Environment.MEDIA_MOUNTED_READ_ONLY) //if you are only interested in reading the filesystem if(!extState.equals(Environment.MEDIA_MOUNTED)) { //handle error here } else { //do your file work here } </code></pre> <p>Once you've determined the proper state of the external storage, a simple way to start is to use File's listFiles() method, like so:</p> <pre><code>//there is also getRootDirectory(), getDataDirectory(), etc. in the docs File sd = Environment.getExternalStorageDirectory(); //This will return an array with all the Files (directories and files) //in the external storage folder File[] sdDirList = sd.listFiles(); </code></pre> <p>You can then start using FileFilters to narrow down your results:</p> <pre><code>FileFilter filterDirectoriesOnly = new FileFilter() { public boolean accept(File file) { return file.isDirectory(); } }; File[] sdDirectories = sd.listFiles(filterDirectoriesOnly); </code></pre> <p>From there on, just read through the docs to find the type of thing you're looking to do with it, and then you can work on tying these into list adapters, etc.</p> <p>Hope this helps!</p>

    1. COOh by the way, I have a working file save and file read script that I've tested and it works, I wanted the file browser I'm creating to just return the Uri of the file you clicked on/directory you selected.

    2. COIn that case, just add a click handler that returns the corresponding File's path (e.g. `sdDirectories[1].getAbsolutePath()`).

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).
