    <p>I am trying to declare a string array which I will be working with in my code. I have done this two ways, both of which I thought to be viable options, but one causes my app to crash on load without fail.</p> <p><strong>Working Code:</strong></p> <pre><code>private String[] list = {"apple", "pear"}; </code></pre> <p><em><strong>Not</em> Working Code:</strong></p> <pre><code>Resources res = getResources(); private String[] list = res.getStringArray(R.array.Fruit); </code></pre> <p>The weird thing is, the latter code was copied <em>directly</em> from the Android String Resource page. I've made sure that the array (In this case titled <code>Fruit</code>) exists, and am now kind of lost.</p> <p>The <strong>Log Cat</strong> Error I am getting is as follows:</p> <pre><code>02-25 12:38:18.015: ERROR/AndroidRuntime(605): FATAL EXCEPTION: main 02-25 12:38:18.015: ERROR/AndroidRuntime(605): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.ikiar.appname/com.ikiar.appname.Main}: java.lang.NullPointerException 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2585) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.app.ActivityThread.access$2300(ActivityThread.java:125) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.os.Handler.dispatchMessage(Handler.java:99) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.os.Looper.loop(Looper.java:123) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.app.ActivityThread.main(ActivityThread.java:4627) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at java.lang.reflect.Method.invokeNative(Native Method) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at java.lang.reflect.Method.invoke(Method.java:521) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at dalvik.system.NativeStart.main(Native Method) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): Caused by: java.lang.NullPointerException 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.content.ContextWrapper.getResources(ContextWrapper.java:80) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at com.ikiar.appname.Main.&lt;init&gt;(Main.java:24) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at java.lang.Class.newInstanceImpl(Native Method) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at java.lang.Class.newInstance(Class.java:1429) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.app.Instrumentation.newActivity(Instrumentation.java:1021) 02-25 12:58:52.284: ERROR/AndroidRuntime(717): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2577) </code></pre> <p>Thank you for your help!</p> <p><strong>EDIT: More Log Cat information, Line of code @ location of crash added</strong></p> <p><em><strong>@ Location of Crash:</em></strong></p> <pre><code>Resources res = getResources(); </code></pre> <p><strong>Solution:</strong></p> <p>Moved the location of <code>Resources res - getResources();</code> into the <code>onCreate</code> method.</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.

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