Body
<code>getFileStreamPath()</code> or <code>openFileOutput()</code> will create files in a private directory that is inaccessible to other apps (i.e. Gmail). Use external storage to create publicly-accessible files: <pre><code>private static final int REQUEST_SHARE = 39714; private File png = null; private void startSendIntent() { png = new File(new File(Environment.getExternalStorageDirectory(), "Pictures"), getString(R.string.file_name)); FileOutputStream out = null; try { out = new FileOutputStream(png); bitmap.compress(Bitmap.CompressFormat.PNG, 100, out); out.flush(); } catch (Exception e) { e.printStackTrace(); } finally { try { if (out != null) out.close(); } catch (IOException ignore) {} } final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(png)); emailIntent.setType("image/png"); startActivityForResult(Intent.createChooser(emailIntent, getString(R.string.send_intent_name)), REQUEST_SHARE); } } </code></pre> This will not work when the external storage is unavailable, like when it is mounted as a USB drive. See the <a href="http://developer.android.com/guide/topics/data/data-storage.html#filesExternal" rel="noreferrer">Storage API Guide</a> for more about detecting whether external storage is available. If your minimum API level is 8 or above, you can use <code>Context.getExternalCacheDir()</code> or <code>Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)</code> as the parent directory. Unless you end up using <code>getExternalCacheDir()</code>, make sure you use a unique filename to prevent one of the users' files from accidentally getting overwritten. Finally, you can override <code>onActivityResult()</code> to delete the file after the share operation completes: <pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data) { if(requestCode == REQUEST_SHARE) { if(this.png == null) { return; } this.png.delete(); } } </code></pre>

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.
