    <p>I created an android app which plays a sound file. When I press the home button I noticed that the sound continues to play and does not stop so I added the following function inside my Class:</p> <pre><code>@Override protected void onStop() { super.onStop(); finish(); //kill the thread pS.reset(); //stop the sound } @Override protected void onPause() { super.onPause(); finish(); //kill the thread pS.reset(); //stop the sound } </code></pre> <p>Which does the job when "Back" or "Home" is pressed, it stops the music and the app does not force close. The only issue is, the sound has to be playing for it to not FC. If there is no sound playing, the app FC. I am guessing it's the </p> <blockquote> <p>pS.reset();</p> </blockquote> <p>function not knowing what to do when the sound isn't playing.</p> <p>If i set it to: </p> <blockquote> <p>pS = null;</p> </blockquote> <p>rather than pS.reset(), will it do the same without FC when "Back" or "Home" is pressed?</p> <p>My pS initialization:</p> <pre><code>pS = MediaPlayer.create(iAct.this, R.drawable.sound); </code></pre> <p>EDIT: I commented out</p> <pre><code>pS.reset(); </code></pre> <p>and added</p> <pre><code>pS = null; </code></pre> <p>it does not FC but the sound does not stop playing.</p> <p>I updated my onPause():</p> <pre><code>@Override protected void onPause() { super.onPause(); if (pS.isPlaying()) { pS.pause(); //stop the sound finish(); } else finish(); } </code></pre> <p>My Log:</p> <pre><code>04-02 13:06:40.563: E/AndroidRuntime(925): FATAL EXCEPTION: main 04-02 13:06:40.563: E/AndroidRuntime(925): java.lang.RuntimeException: Unable to pause activity {com.testcom.myapp/com.testcom.myapp.MyappActivity}: java.lang.NullPointerException 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.ActivityThread.performPauseActivity(ActivityThread.java:2354) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.ActivityThread.performPauseActivity(ActivityThread.java:2311) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.ActivityThread.handlePauseActivity(ActivityThread.java:2291) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.ActivityThread.access$1700(ActivityThread.java:117) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:938) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.os.Handler.dispatchMessage(Handler.java:99) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.os.Looper.loop(Looper.java:123) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.ActivityThread.main(ActivityThread.java:3683) 04-02 13:06:40.563: E/AndroidRuntime(925): at java.lang.reflect.Method.invokeNative(Native Method) 04-02 13:06:40.563: E/AndroidRuntime(925): at java.lang.reflect.Method.invoke(Method.java:507) 04-02 13:06:40.563: E/AndroidRuntime(925): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 04-02 13:06:40.563: E/AndroidRuntime(925): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 04-02 13:06:40.563: E/AndroidRuntime(925): at dalvik.system.NativeStart.main(Native Method) 04-02 13:06:40.563: E/AndroidRuntime(925): Caused by: java.lang.NullPointerException 04-02 13:06:40.563: E/AndroidRuntime(925): at com.testcom.myapp.MyappActivity.onPause(MyappActivity.java:119) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.Activity.performPause(Activity.java:3851) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.Instrumentation.callActivityOnPause(Instrumentation.java:1191) 04-02 13:06:40.563: E/AndroidRuntime(925): at android.app.ActivityThread.performPauseActivity(ActivityThread.java:2341) 04-02 13:06:40.563: E/AndroidRuntime(925): ... 12 more </code></pre>

    1. COFirst of all: What's your Logcat output? It should point you directly to the source of your FC. Secondly: I hope that's a typo, but you're calling super.onStop() in your override of onPause() !! This is NOT right, you'd have to call super.onPause() in your onPause override. Furthermore: Why do you finish your Activity in onPause/onStop?

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.
