Here is the code I use to bring up the activity: <pre><code>startActivity(new Intent(getApplicationContext(), Giveaway.class)); </code></pre> Here is the Activity that I am bringing up: <pre><code>public class Giveaway extends Activity implements OnClickListener{ static SharedPreferences settings; SharedPreferences.Editor prefEditor; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.giveaway); settings = getSharedPreferences("firsttime", 0); LinearLayout facebook = (LinearLayout)findViewById(R.id.facebooklayout); Button later = (Button)findViewById(R.id.later); Button dontshowagain = (Button)findViewById(R.id.dontshowagain); facebook.setOnClickListener(this); later.setOnClickListener(this); dontshowagain.setOnClickListener(this); } public void onClick(View v) { switch (v.getId()) { case R.id.facebooklayout: Uri localuri = Uri.parse("http://www.facebook.com/pages/Bright-Design/366832480049386"); startActivity(new Intent("android.intent.action.VIEW", localuri)); break; case R.id.later: finish(); break; case R.id.dontshowagain: finish(); prefEditor = settings.edit(); prefEditor.putBoolean("showgiveaway", false); prefEditor.commit(); break; } } </code></pre> I have declared the Activity in my manifest folder: <pre><code><activity android:name=".Giveaway" android:label="@string/app_name" android:theme="@android:style/Theme.Dialog" android:screenOrientation="portrait"/> </code></pre> But I keep getting a java.lang.RuntimeException: Unable to start activity java.lang.NullPointerException error. Here is my logcat: <pre><code> 07-24 12:43:59.082: E/AndroidRuntime(7039): FATAL EXCEPTION: main 07-24 12:43:59.082: E/AndroidRuntime(7039): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.brightdesign.blackops2/com.brightdesign.blackops2.Giveaway}: java.lang.NullPointerException 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.app.ActivityThread.access$2300(ActivityThread.java:125) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.os.Handler.dispatchMessage(Handler.java:99) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.os.Looper.loop(Looper.java:123) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.app.ActivityThread.main(ActivityThread.java:4627) 07-24 12:43:59.082: E/AndroidRuntime(7039): at java.lang.reflect.Method.invokeNative(Native Method) 07-24 12:43:59.082: E/AndroidRuntime(7039): at java.lang.reflect.Method.invoke(Method.java:521) 07-24 12:43:59.082: E/AndroidRuntime(7039): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 07-24 12:43:59.082: E/AndroidRuntime(7039): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 07-24 12:43:59.082: E/AndroidRuntime(7039): at dalvik.system.NativeStart.main(Native Method) 07-24 12:43:59.082: E/AndroidRuntime(7039): Caused by: java.lang.NullPointerException 07-24 12:43:59.082: E/AndroidRuntime(7039): at com.brightdesign.blackops2.Giveaway.onCreate(Giveaway.java:29) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-24 12:43:59.082: E/AndroidRuntime(7039): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2627) </code></pre>

Guidance

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.
