    <p>Im trying to make a Notification Activity that other classes can reuse and put in extra information. What i am struggling with is how to correctly call the method from another class.</p> <p>Code for Notification Activity:</p> <p>public class NotificationTest extends MyActivity{</p> <pre><code>public void showNotification(String s, Context c) { // define sound URI, the sound to be played when there's a notification Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); // intent triggered, you can add other intent for other actions //Intent intent = new Intent(Sender context, which class to start); Intent intent = new Intent(c, Settings.class); //PendingIntent pIntent = PendingIntent.getActivity(sender context, 0, intent, 0); PendingIntent pIntent = PendingIntent.getActivity(c, 0, intent, 0); // this is it, we'll build the notification! // in the addAction method, if you don't want any icon, just set the first param to 0 Notification mNotification = new Notification.Builder(c) .setContentTitle("New Post!") .setContentText(s) .setSmallIcon(R.drawable.icon) .setContentIntent(pIntent) .setSound(soundUri) //.addAction(R.drawable.icon, "View",pIntent) //.addAction(0, "Remind", pIntent) .build(); Log.d("Vindsiden", "Notification"); NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); // If you want to hide the notification after it was selected, do the code below // myNotification.flags |= Notification.FLAG_AUTO_CANCEL; notificationManager.notify(0, mNotification); } } </code></pre> <p>Code for calling the Notification from for example MyActivity :</p> <pre><code>String s= "Notification"; NotificationTest notificationTest = new NotificationTest(); notificationTest.showNotification(s,MyActivity.this); </code></pre> <p>The error im getting is : </p> <pre><code>12-05 19:20:34.004 22352-22352/com.vindsiden.windwidget E/AndroidRuntime﹕ FATAL EXCEPTION: main Process: com.vindsiden.windwidget, PID: 22352 java.lang.IllegalStateException: System services not available to Activities before onCreate() at android.app.Activity.getSystemService(Activity.java:4531) at com.vindsiden.windwidget.NotificationTest.showNotification(NotificationTest.java:66) at com.vindsiden.windwidget.MyActivity$1.onClick(MyActivity.java:52) at android.view.View.performClick(View.java:4424) at android.view.View$PerformClick.run(View.java:18383) at android.os.Handler.handleCallback(Handler.java:733) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:4998) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:777) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:593) </code></pre>

    1. COI believe you should put your notification code in separate class (not an Activity) and call it statically from other activities. Otherwise you can place it in your base Activity and each child activity will be able to call your notification.

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.
