    <p>Having a problem with my Android application. I currently have a <code>CatDownloadService</code> which is suppose to do 2 things in the background:</p> <ol> <li>Download the information of the cat (id, name, imageid, etc...) from the server as JSON</li> <li>Parse the JSON into an Cat object</li> <li>Insert the Cat object into the database through a CatDatabaseAccessObject</li> <li>Download image of cat</li> <li>Save image onto external storage.</li> </ol> <p>I can't seem to decide between the various ways of achieving this. Can someone point me into the right direction? What I understand about each method is in the ().</p> <p><strong>Parse JSON</strong></p> <ol> <li><p>method in CatDownloadService (Since my JSON parsing would only be needed in this class)</p> <pre><code>parseCatJSON(jsonString); </code></pre></li> <li><p>method in CatJSONParser.java (Neater, since the logic for JSON parsing is in a class by itself)</p> <pre><code>CatJSONParser catJsonParser = new CatJSONParser(); catJsonParser.parseCatJSON(jsonString); </code></pre></li> <li><p>static method in CatJSONParser.java (Same as 2. Don't need object creation)</p> <pre><code>CatJSONParser.parseCatJSON(jsonString); </code></pre></li> </ol> <p><strong>Add into database through DatabaseAccessObject</strong></p> <ol> <li><p>method in CatDatabaseAccessObject.java (Each context that uses the DBHelper is different)</p> <pre><code>CatDatabaseAccessObject catDAO = new CatDatabaseAccessObject(this); catDAO.addCat(cat); </code></pre></li> <li><p>static method in CatDatabaseAccessObject.java (Ensure there is only 1 connection to DB)</p> <pre><code>CatDatabaseAccessObject.addCat(cat); </code></pre></li> </ol> <p><strong>Save Cat image to external storage</strong></p> <ol> <li><p>method in CatStorageManager.java</p> <pre><code>CatStorageManager catStorageManager = new CatStorageManager(); catStorageManager.writeCatImage(catInputStream); </code></pre></li> <li><p>static method in CatStorageManager.java</p> <pre><code>CatStorageManager.writeCatImage(catInputStream); </code></pre></li> </ol> <p>I'm really lost.</p>

    1. COAlthough this probably isn't particularly helpful, I think it probably depends on your overall solution design. I personally have tended to use static methods in a class for managing reading from and writing to databases, but then it has made sense in the solutions I have been working with. It feels conceptually simpler to me. I am sure there are reasons you wouldn't want to do that in other designs.

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.

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