    <p><strong>READ UPDATE 2 BELOW FOR THE ANSWER</strong></p> <p>I'm trying to use ActionBarSherlock in my app. I checked out the 4.0.0 release from the <a href="https://github.com/JakeWharton/ActionBarSherlock" rel="noreferrer">project github repo</a>, built it in Netbeans, then copied the library-4.0.0.jar file into my project's lib directory (I'm not using Eclipse).</p> <p>It's just a skeleton activity right now, and it launches just fine in ICS, but when I run it on Gingerbread I get the following exception complaining that I haven't the app theme to Theme.Sherlock (or similar):</p> <pre><code>java.lang.RuntimeException: Unable to start activity ComponentInfo{com.arashpayan.prayerbook/com.arashpayan.prayerbook.PrayerBook}: java.lang.IllegalStateException: You must use Theme.Sherlock, Theme.Sherlock.Light, Theme.Sherlock.Light.DarkActionBar, or a derivative. at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1647) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1663) at android.app.ActivityThread.access$1500(ActivityThread.java:117) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:130) at android.app.ActivityThread.main(ActivityThread.java:3683) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:507) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.IllegalStateException: You must use Theme.Sherlock, Theme.Sherlock.Light, Theme.Sherlock.Light.DarkActionBar, or a derivative. at com.actionbarsherlock.internal.ActionBarSherlockCompat.generateLayout(ActionBarSherlockCompat.java:987) at com.actionbarsherlock.internal.ActionBarSherlockCompat.installDecor(ActionBarSherlockCompat.java:899) at com.actionbarsherlock.internal.ActionBarSherlockCompat.setContentView(ActionBarSherlockCompat.java:852) at com.actionbarsherlock.ActionBarSherlock.setContentView(ActionBarSherlock.java:655) at com.actionbarsherlock.app.SherlockFragmentActivity.setContentView(SherlockFragmentActivity.java:316) at com.arashpayan.prayerbook.PrayerBook.onCreate(PrayerBook.java:44) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1611) ... 11 more </code></pre> <p>The line it complains about (PrayerBook:44) is the call to <code>setContentView</code>. The app just consists of a single activity with an <code>onCreate()</code> method that I call <code>setTheme()</code> from at the top:</p> <pre><code>public void onCreate(Bundle savedInstanceState) { setTheme(com.actionbarsherlock.R.style.Theme_Sherlock); super.onCreate(savedInstanceState); TextView rootTextView = new TextView(this); rootTextView.setText("Hello, world!"); setContentView(rootTextView); getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); ActionBar.Tab tab = getSupportActionBar().newTab(); tab.setText("Prayers"); getSupportActionBar().addTab(tab); tab = getSupportActionBar().newTab(); tab.setText("Recents"); getSupportActionBar().addTab(tab); tab = getSupportActionBar().newTab(); tab.setText("Bookmarks"); getSupportActionBar().addTab(tab); } </code></pre> <p>I must be setting the theme incorrectly, but I just don't see how. Can anyone help?</p> <p><b>UPDATE</b> Below, CommonsWare noted that the theme can be set in the AndroidManifest.xml. I've tried that like so:</p> <pre><code>&lt;application android:label="@string/app_name" android:icon="@drawable/icon" android:theme="@style/Theme.Sherlock"&gt; &lt;activity android:name="PrayerBook" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden|screenLayout|uiMode|mcc|mnc|locale|navigation|fontScale|screenSize"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name="LanguagesActivity" /&gt; &lt;/application&gt; </code></pre> <p>but Ant gives me an error when it tries to build the app:</p> <pre><code>/Users/arash/coding/prayerbook/AndroidManifest.xml:7: error: Error: No resource found that matches the given name (at 'theme' with value '@style/Theme.Sherlock'). </code></pre> <p><strong>UPDATE 2</strong> With CommonsWare's help in his follow up comments, I was able to get it working. I needed to add ActionBarSherlock as a project dependency. To do so,</p> <p>1) I removed <code>library-4.0.0.jar</code> and <code>android-support-4.0.jar</code> from my project's <code>lib</code> directory.</p> <p>2) Next, navigate into the <code>library</code> folder inside the root of the ActionBarSherlock directory checked out from github. Type <code>android update project</code> so a <code>build.xml</code> and <code>proguard.cfg</code> file will be created for the library.</p> <p>3) Finally, <code>cd</code> back into the main project directory and add ABS as a library dependency with <code>android update project --path . --library ../ActionBarSherlock/library</code> The path to the <code>--library</code> in the command will vary according to where you checked out the repo. ActionBarSherlock and my app's project directory were sibling directories.</p>

    2. COThat was the first place I checked. In the ABS demos app, the static THEME member of the SampleList class is initialized to R.style.Theme_Sherlock but never used in that activity except for changing it's stored value from the options menu. All activities started from that main activity call setTheme() with that constant as the argument at the very top of their onCreate() method, which is why I do the same in my code. You'll notice the same instruction is also listed in the second paragraph of the 'Parent Themes' section on the ABS site. http://actionbarsherlock.com/theming.html

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.
