我有一个带有状态栏图标的简单应用程序。当用户最小化应用程序时，会出现状态栏图标。当用户单击该图标时，应用程序应恢复并继续工作。我已经在 android 2.3.4 上进行了测试，它可以工作，但是在 4.0 android 版本上，我的应用程序没有恢复并继续工作，而是打开了我的应用程序的新版本。如何制作通用通知码，不用担心安卓版本？

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_jajko);

    text = (TextView) findViewById(R.id.tvTime);
    play = (Button) findViewById(R.id.butStart);
    miekko = (Button) findViewById(R.id.butMiekko);
    srednio = (Button) findViewById(R.id.butSrednio);
    twardo = (Button) findViewById(R.id.butTwardo);

    miekko.setOnClickListener(this);
    srednio.setOnClickListener(this);
    twardo.setOnClickListener(this);
    play.setOnClickListener(this);

    mp = MediaPlayer.create(Jajko.this, R.raw.alarm);

    showNotification(this);

}

public static void showNotification(Context context) {
    final Intent result_intent = new Intent(context, Jajko.class);

    result_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    TaskStackBuilder stack_builder = TaskStackBuilder.create(context);
    stack_builder.addParentStack(Jajko.class);
    stack_builder.addNextIntent(result_intent);

    PendingIntent pending_intent = stack_builder.getPendingIntent(0,
            PendingIntent.FLAG_UPDATE_CURRENT);

    android.support.v4.app.NotificationCompat.Builder builder = new android.support.v4.app.NotificationCompat.Builder(
            context);

    Resources res = context.getResources();
    builder.setContentIntent(pending_intent)
            .setSmallIcon(R.drawable.icon)
            .setLargeIcon(
                    BitmapFactory.decodeResource(res, R.drawable.icon))
            .setTicker("Egg Timer").setWhen(System.currentTimeMillis())
            .setAutoCancel(false).setContentTitle("Egg Timer")
            .setContentInfo("").setContentText("");
    Notification n = builder.build();
    n.flags = Notification.FLAG_ONGOING_EVENT;

    notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIF_ID, n);
}

The documentation for TaskStackBuilder says that it behaves differently on pre- and post-3.0 Android. I haven't used it for a pending intent, so I'm not sure what to expect with that.

Try completely removing the three lines with the stack builder, and change your pending intent line to this:

PendingIntent pending_intent = PendingIntent.getActivity(getBaseContext(), 
    0, result_intent, PendingIntent.FLAG_UPDATE_CURRENT);
