用的雷电模拟器，无法显示悬浮窗自定义的图片，但是点击拖拽功能正常，只是肉眼看不到。怎么回事啊

var img_url = "file://storage/emulated/0/demo.jpg"

suspendedWindow();

function suspendedWindow() {

window = floaty.rawWindow(
    <horizontal gravity="center_vertical">
        <img id="floaty_icon" src="{{img_url}}" w="40" h="40" alpha="0.8" circle="true" borderWidth="1dp" borderColor="black" />
        <horizontal id="h_drawer">
            <vertical>
                <button id="ui_start" textColor="#FFFFFF" text="开始" bg="#4F4F4F" padding="0" h="40" w="50" />
                <text text="" h="1" />
                <button id="ui_close" textColor="#FFFFFF" text="结束" bg="#4F4F4F" padding="0" h="40" w="50" />
            </vertical>
        </horizontal>
    </horizontal>
);
window.setPosition(50, device.height / 3);
window.exitOnClose();
setInterval(() => { }, 1000);

window.h_drawer.visibility = 8;
