    <p>I am a noob at writing Android apps, I have a problem using <code>getResources().getStringArray()</code>.</p> <p>I make an <code>string-array</code> resource from Eclipse (or by hand) in a file called <em>res.values.strings.xml</em> looking like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;resources&gt; &lt;string-array name="BlueStartCommands"&gt; &lt;item&gt; NO_CMD&lt;/item&gt; &lt;item&gt; LOCK_CMD&lt;/item&gt; &lt;item&gt; UNLOCK_CMD&lt;/item&gt; &lt;item&gt; TRUNK_RELEASE_CMD&lt;/item&gt; &lt;item&gt; PANIC_CMD&lt;/item&gt; &lt;item&gt; REMOTE_START_CMD&lt;/item&gt; &lt;item&gt; REQ_START_MONITOR_CMD&lt;/item&gt; &lt;item&gt; REQ_PASSIVE_LOCK_SETTINGS_CMD&lt;/item&gt; &lt;item&gt; REQ_STOP_MONITOR_CMD&lt;/item&gt; &lt;item&gt; PING_CMD&lt;/item&gt; &lt;/string-array&gt; &lt;string-array name="CMD"&gt; &lt;item&gt;AAAAAA&lt;/item&gt; &lt;item&gt;BBBBBB&lt;/item&gt; &lt;/string-array&gt; &lt;/resources&gt; </code></pre> <p>I then try to access the array in my <code>Activity</code>. It crashes:</p> <pre><code>public class TestApp2Activity extends Activity { static boolean firstWrite=true; TextView DebugWindow; ViewFlipper flipper; Button FlipBtn; Button SwitchBtn; EditText MessageBox; Spinner PredefinedMessages; OnItemSelectedListener PredefinedMessageSelected; int SelectedPredefinedMessage=0; String[] MyPredefinedCommands = {"fsd", "fdg", "sdf", "saf", "w", "v", "u", "t", "z", "y", "x"}; String[] cmd = getResources().getStringArray(R.array.CMD); @SuppressWarnings("unchecked") @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); flipper=(ViewFlipper)findViewById(R.id.details); FlipBtn=(Button)findViewById(R.id.Button01); SwitchBtn=(Button)findViewById(R.id.Button04); DebugWindow=(TextView)findViewById(R.id.textView1); MessageBox=(EditText)findViewById(R.id.editText2); PredefinedMessages=(Spinner)findViewById(R.id.spinner1); PredefinedMessages.setPrompt("Please enter a predefined command"); @SuppressWarnings("rawtypes") ArrayAdapter adapter = ArrayAdapter.createFromResource( this, R.array.BlueStartCommands , android.R.layout.simple_spinner_item); PredefinedMessages.setAdapter(adapter); PredefinedMessages.setOnItemSelectedListener(new ListView.OnItemSelectedListener() { @Override public void onItemSelected(AdapterView&lt;?&gt; a, View v, int i, long l) { try { // Remembers the selected Index SelectedPredefinedMessage = i; String s = MyPredefinedCommands[i]; System.out.print(s); MessageBox.setText(cmd[i]); } catch(Exception e) { System.out.println("Nay, cannot get the selected index"); } } @Override public void onNothingSelected(AdapterView&lt;?&gt; arg0) { // TODO Auto-generated method stub } }); } </code></pre> <p>However, when I use the code created <code>array-string</code> <em>cmd</em>, it works! Why is that?</p>

    1. COWhat ever resource we use in our app android framework creates static reference to them in R.java whole strings.xml is converted to objects when you call getresource(id) it is something like DOM not exactly.

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).
