未经绑定权限将小部件添加到我的自定义启动器的主屏幕

Question

我正在基于Launcher 3构建自定义的Launcher，我想在安装Launcher时将一个小部件添加到Launcher主屏幕，但要避免绑定权限对话框.Launcher 3提供了default_launcher.xml，您可以在其中放置appwidget标记，但是由于bindAppWidgetIdIfAllowed返回的值为“ false”，因此它将删除defaultLayoutparser的AppWidgetParser方法中的appwidgetid。如何将预配置的小部件添加到启动器主屏幕

AppWidgetParser类扩展了PendingWidgetParser {

    protected long verifyAndInsert(ComponentName cn, Bundle extras) {
        try {
            mPackageManager.getReceiverInfo(cn, 0);
        } catch (Exception e) {
            String[] packages = mPackageManager.currentToCanonicalPackageNames(
                    new String[] { cn.getPackageName() });
            cn = new ComponentName(packages[0], cn.getClassName());
            try {
                mPackageManager.getReceiverInfo(cn, 0);
            } catch (Exception e1) {
                Log.d(TAG, "Can't find widget provider: " + cn.getClassName());
                return -1;
            }
        }

        final AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(mContext);
        long insertedId = -1;
        try {
            int appWidgetId = mAppWidgetHost.allocateAppWidgetId();

            if (!appWidgetManager.bindAppWidgetIdIfAllowed(appWidgetId, cn)) {
                Log.e(TAG, "Unable to bind app widget id " + cn);
                mAppWidgetHost.deleteAppWidgetId(appWidgetId);// here it removes the appWidgetId
                return -1;
            }

            mValues.put(Favorites.APPWIDGET_ID, appWidgetId);
            mValues.put(Favorites.APPWIDGET_PROVIDER, cn.flattenToString());
            mValues.put(Favorites._ID, mCallback.generateNewItemId());
            insertedId = mCallback.insertAndCheck(mDb, mValues);
            if (insertedId < 0) {
                mAppWidgetHost.deleteAppWidgetId(appWidgetId);
                return insertedId;
            }

            // Send a broadcast to configure the widget
            if (!extras.isEmpty()) {
                Intent intent = new Intent(ACTION_APPWIDGET_DEFAULT_WORKSPACE_CONFIGURE);
                intent.setComponent(cn);
                intent.putExtras(extras);
                intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
                mContext.sendBroadcast(intent);
            }
        } catch (RuntimeException ex) {
            Log.e(TAG, "Problem allocating appWidgetId", ex);
        }
        return insertedId;
    }
}
