Question

Code is written down to update the widget.

this code works always

Toast.makeText(context, ""+cd.getId(), Toast.LENGTH_LONG).show();

But nether code only works when it is Debug.

@Override
public void onUpdate(Context context, AppWidgetManager appwidgetmanager,
        int[] appWidgetIds) {

    for (int i : appWidgetIds) {
        RemoteViews views = new RemoteViews(context.getPackageName(),
                R.layout.widget4x4persian);
        shaffle(context, appwidgetmanager, i, views);
    }

}

@Override
public void onReceive(Context context, Intent intent) {
    this.context = context;
    super.onReceive(context, intent);
    ComponentName thisWidget = new ComponentName(context, gift4x4.class);
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
            R.layout.widget4x4persian);
    AppWidgetManager appWidgetManager = AppWidgetManager
            .getInstance(context);
    appWidgetManager.updateAppWidget(thisWidget, remoteViews);
    clickWidget(context, appWidgetManager, intent, remoteViews);
}

private void clickWidget(Context context,
        AppWidgetManager appWidgetManager, Intent intent,
        RemoteViews remoteViews) {

    Cursor c = null;
    try {

        ComponentName thisWidget = new ComponentName(context, gift4x4.class);

        Bundle b = intent.getExtras();

        if (b != null) {
            int key = b.getInt(WIDGET_KEY);

            String id = null;

                int[] allWidgetIds = appWidgetManager
                        .getAppWidgetIds(thisWidget);
                for (int i : allWidgetIds) {
                    RemoteViews views = new RemoteViews(
                            context.getPackageName(),
                            R.layout.widget4x4persian);
                    shaffle(context, appWidgetManager, i, remoteViews);
                }
            }

        e.getMessage();
    } finally {
        if (c != null)
            c.close();
    }
}

public void shaffle(Context context, AppWidgetManager appwidgetmanager,
        int appWidgetId, RemoteViews Rview) {
    Cursor c = null;
    try {

        Card cd = null;
        do {
            PreferenceManager pm = new PreferenceManager(context);
            Cards_Count = pm.get(PREFNAME_CARDS_COUNTS, CARDS_COUNTS);
            int shaffle = (new Random()).nextInt(Cards_Count);

            c = context.getContentResolver().query(CONTENT_URI_CARDS,
                    new String[] { ID, TEXT, ISREAD, ISBOOKMARK, NOTE },
                    "id=" + shaffle, null, null);
            if (c.moveToFirst()) {

                        .getColumnIndex(TEXT)), c.getInt(c
                        .getColumnIndex(ISREAD)), c.getInt(c
                        .getColumnIndex(ISBOOKMARK)), c.getString(c

            }
            c.close();
        } while (c == null);

        Rview.setImageViewResource(R.id.imgIsBookmarkWidget, cd
                .getIsBookmark() == 1 ? R.drawable.bookmark
                : R.drawable.unbookmark);

        Bitmap bmp = getPicture(context, cd.getId());
                    Toast.makeText(context, ""+cd.getId(), Toast.LENGTH_LONG).show();

Maybe the Context you are using is not the right type.
Just use the context which is passed into function, don’t use private contexts declared in class.

public void onReceive(Context context, Intent intent)
