android - 销毁后状态栏图标无法删除

Question

销毁应用程序已解决！感谢帮助！现在活动被破坏，但状态图标仍然出现在状态栏上。你能在应用程序关闭的同时帮我删除图标吗？我怀疑 onDestroy 部分的问题...

private static final int NOTIF_ID = 1;

@Override
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("test")
        .setWhen(System.currentTimeMillis())
        .setAutoCancel(false)
        .setContentTitle("title")
        .setContentInfo("cinfo")
        .setContentText("ctext");
    Notification n = builder.build();
    n.flags = Notification.FLAG_ONGOING_EVENT; 

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

public void onDestroy() {
try {
    mp.release();
    if (isFinishing()) {
        notificationManager.cancel(NOTIF_ID);
    }
} catch (Exception e) {
}
super.onDestroy();

}

Answer 1

尝试调用“killProcess”方法

@Override
public void onDestroy() {
    super.onDestroy();
    android.os.Process.killProcess(android.os.Process.myPid());
}

Answer 2

// try this way
@Override
    public void onDestroy() {
        if(isFinishing()){
            notificationManager.cancelAll();
        }
        super.onDestroy();
}
