Question

我使用Launcher2 home screen作为自定义主屏幕的基础。我想用默认的Widget自定义Android主屏幕。

但是当我使用这个例子时，我收到了这个错误：

我已经在我的清单中添加了android.permission.BIND_APPWIDGET，但它仍然无效，我的默认小部件仍然缺失。

有没有人知道会出现什么问题？

android.permission.BIND_APPWIDGET不适用于系统存储之外的应用程序。

如果没有完整的堆栈跟踪，我无法确定错误的确切位置，但这是我所期望的导致问题。

void addAppWidget(Intent data) {
        int appWidgetId = data.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1);
        AppWidgetProviderInfo appWidget = mAppWidgetManager.getAppWidgetInfo(appWidgetId);

        if (appWidget.configure != null) {
            // Launch over to configure widget, if needed
            Intent intent = new Intent(AppWidgetManager.ACTION_APPWIDGET_CONFIGURE);
            intent.setComponent(appWidget.configure);
            intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);

            startActivityForResultSafely(intent, REQUEST_CREATE_APPWIDGET);
        } else {
            // Otherwise just add it
            onActivityResult(REQUEST_CREATE_APPWIDGET, Activity.RESULT_OK, data);
        }
}

如何在自定义Android主屏幕中添加默认小部件？
