    <p>Are you doing this work on the main thread? I recommend using an <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">AsyncTask</a> with a <a href="http://developer.android.com/reference/android/app/ProgressDialog.html" rel="nofollow">ProgressDialog</a> so that the work is done in the background while your UI waits for the response. Using runnables for uploading is not a good idea. Any background thread that is built into android should have performance gains. Especially because the user will see an indeterminate progress dialog which is more pleasing than an app that is being held up for no known apparent reason.</p> <p>Alternatively if you are using an Amazon S3 server to store your uploads, you might want to use a third party library like <a href="https://github.com/jgilfelt/android-simpl3r" rel="nofollow">Simpl3r</a>.</p> <p>If an AsyncTask or Simpl3r aren't your cup of tea. An <a href="http://developer.android.com/reference/android/app/IntentService.html" rel="nofollow">Intent Service</a> is a great option for background uploads, as the uploading process is completely decoupled from your activity. When finished uploading you can update local storage data for when the user returns to that activity.</p> <p>1) There is no reason why you should need to change anything about an image to upload it. Especially if it is small.</p> <p>2) I recommend no callbacks. Use local storage, such as a database where you can then update the information locally once the upload has finished. When returning to the activity/fragment you began the upload, you can load this local data using an AsyncTask/AsyncTaskLoader/CursorLoader etc. Many options exist for changing live data in your app.</p> <p>3) Many patterns exist, some of my favorites I have listed here.</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.
