    <p>R class on android has it's limitations. You can't use the resources dynamically for loading audio, pictures or whatever. If you wan't for example, load a set of audio files for a choosen object you can't do something like:</p> <pre><code>R.raw."string-upon-choosen-object" </code></pre> <p>I'm new to android and at least I didn't find how you could do that, depending on what objects are choosen or something more dynamic than that. So, I thought about making it dynamic with a little of memory overhead. But, I'm in doubt if it's worth it or just working different with external resources.</p> <h2>The idea is this:</h2> <p>Modify the ant build xml to execute my own task. This task, is a java program that parses the R.java file building a set of HashMaps with it's pair (key, value). I have done this manually and It's working good. So I need some experts voice about it. </p> <p>This is how I will manage the whole thing:</p> <p>Generate a base <code>Application</code> class, e.g. <code>MainApplicationResources</code> that builds up all the require methods and attributes. Then, you can access those methods invoking <code>getApplication()</code> and then the desired method. </p> <p>Something like this:</p> <pre><code> package [packageName] import android.app.Application; import java.util.HashMap; public class MainActivityResources extends Application { private HashMap&lt;String,Integer&gt; [resNameObj1]; private HashMap&lt;String,Integer&gt; [resNameObj2]; ... private HashMap&lt;String,Integer&gt; [resNameObjN]; public MainActivityResources() { super(); [resNameObj1] = new HashMap&lt;String,Integer&gt;(); [resNameObj1].put("[resNameObj1_Key1]", new Integer([resNameObj1_Value1])); [resNameObj1].put("[resNameObj1_Key2]", new Integer([resNameObj1_Value2])); [resNameObj2] = new HashMap&lt;String,Integer&gt;(); [resNameObj2].put("[resNameObj2_Key1]", new Integer([resNameObj2_Value1])); [resNameObj2].put("[resNameObj2_Key2]", new Integer([resNameObj2_Value2])); ... [resNameObjN] = new HashMap&lt;String,Integer&gt;(); [resNameObjN].put("[resNameObjN_Key1]", new Integer([resNameObjN_Value1])); [resNameObjN].put("[resNameObjN_Key2]", new Integer([resNameObjN_Value2])); } public int get[ResNameObj1](String resourceName) { return [resNameObj1].get(resourceName).intValue(); } public int get[ResNameObj2](String resourceName) { return [resNameObj2].get(resourceName).intValue(); } ... public int get[ResNameObjN](String resourceName) { return [resNameObjN].get(resourceName).intValue(); } } </code></pre> <h2>The question is:</h2> <p>Will I add too much memory use of the device? Is it worth it?</p> <p>Regards,</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.
