<p>Whenever I click my button my app crashes. What am I doing wrong?</p> <pre><code>public void onClick(View v) { int primaryLength = PRIMARY.length; final String primaryText = PRIMARY[rnd.nextInt(primaryLength)]; int secondaryLength = SECONDARY.length; final String secondaryText = SECONDARY[rnd.nextInt(secondaryLength)]; final TextView textOne = (TextView)findViewById(R.id.textView1); final TextView textTwo = (TextView)findViewById(R.id.textView2); textOne.setText(primaryText); textTwo.setText(secondaryText); String primeT = primaryText; Uri media = Uri.parse(primeT); mpButtonOne = MediaPlayer.create(MainActivity.this, media); mpButtonOne.start(); mpButtonOne.setOnCompletionListener(new OnCompletionListener() { public void onCompletion(MediaPlayer mpButtonOne) { String primeS = secondaryText; Uri media2 = Uri.parse(primeS); mpButtonTwo = MediaPlayer.create(MainActivity.this, media2); mpButtonTwo.start(); mpButtonTwo.setOnCompletionListener(new soundListener1()); { } } </code></pre> <p>I want the randomly selected text that is displayed in textviews to be entered as the location for the mediaplayer sound files, the words are the names of the sound files in my raw folder. I'm a bit new and really not sure if this is the right way to go about it.</p> <pre><code>09-11 16:50:40.128: E/AndroidRuntime(12531): FATAL EXCEPTION: main 09-11 16:50:40.128: E/AndroidRuntime(12531): java.lang.NullPointerException 09-11 16:50:40.128: E/AndroidRuntime(12531): at com.spunktrunk.nastylittleman.MainActivity$1.onClick(MainActivity.java:62) 09-11 16:50:40.128: E/AndroidRuntime(12531): at android.view.View.performClick(View.java:2408) 09-11 16:50:40.128: E/AndroidRuntime(12531): at android.view.View$PerformClick.run(View.java:8816) 09-11 16:50:40.128: E/AndroidRuntime(12531): at android.os.Handler.handleCallback(Handler.java:587) 09-11 16:50:40.128: E/AndroidRuntime(12531): at android.os.Handler.dispatchMessage(Handler.java:92) 09-11 16:50:40.128: E/AndroidRuntime(12531): at android.os.Looper.loop(Looper.java:123) 09-11 16:50:40.128: E/AndroidRuntime(12531): at android.app.ActivityThread.main(ActivityThread.java:4669) 09-11 16:50:40.128: E/AndroidRuntime(12531): at java.lang.reflect.Method.invokeNative(Native Method) 09-11 16:50:40.128: E/AndroidRuntime(12531): at java.lang.reflect.Method.invoke(Method.java:521) 09-11 16:50:40.128: E/AndroidRuntime(12531): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:876) 09-11 16:50:40.128: E/AndroidRuntime(12531): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:634) 09-11 16:50:40.128: E/AndroidRuntime(12531): at dalvik.system.NativeStart.main(Native Method) 09-11 16:50:40.128: W/ActivityManager(237): Force finishing activity com.spunktrunk.nastylittleman/.MainActivity </code></pre>

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.
