    <p>I am getting a null pointer exception report in the android developer console. I need some advise as to what possibly is the problem here, the stack trace is like this</p> <pre><code>java.lang.NullPointerException at com.myfreeapp.workers.Speaker.onInit(Speaker.java:57) at android.speech.tts.TextToSpeech$1.onServiceConnected(TextToSpeech.java:451) at android.app.ActivityThread$PackageInfo$ServiceDispatcher.doConnected(ActivityThread.java:1247) at android.app.ActivityThread$PackageInfo$ServiceDispatcher$RunConnection.run(ActivityThread.java:1264) at android.os.Handler.handleCallback(Handler.java:587) at android.os.Handler.dispatchMessage(Handler.java:92) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4668) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:878) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:636) at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>The relevant code snippet in my app is </p> <pre><code>public Speaker(final Context context, final Settings settings) { this.settings = settings; params = new HashMap&lt;String, String&gt;(); params.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_ALARM)); params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "myfreeapps"); tts= new TextToSpeech(context, this); Utils.log(TAG, "Created TextToSpeech.."); } @Override public void onInit(final int status) { Utils.log(TAG, "TTS onInit.."); //below is line 57 mentioned in the stack trace tts.setOnUtteranceCompletedListener(new SpeechFinishedListener()); tts.setLanguage(Locale.getDefault()); tts.setSpeechRate(settings.getSpeed()); tts.setPitch(settings.getPitch()); ready = true; } </code></pre> <p>Please first of all I need to be clear what exactly is null.. Is the stack trace pointing to variable tts on line 57 to be null..?</p> <p>Or is the null pointer exception happening inside the TextToSpeech method setOnUtteranceCompletedListener ?</p> <p>The Speaker instance is created on the main thread in a sticky service, and when I debug my code the callback from TextToSpeech also comes back on the same thread..</p> <p>I don't understand how could the variable tts be null ??? </p> <p>By the way this problem is not reproducible on my end. I have this stack strace reported several times on the developer console.</p> <p>Please advise, </p>

    1. COIs their a reason you are initializing your TextToSpeech object in the constructor versus inside onInit?

    2. COWell, onInit is called as a result of creating TextToSpeech(context, this); the second param to TextToSpeech constructor is the implementaion of OnInitListener which has the method onInit.. Speech class is implementing OnInitListener interface..

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.
