uni-app（安卓）标准基座和自定义基座均可以正常运行，但是云打包过后，APP白屏（可以看到tabBar）

实在没办法，每个页面一行一行注释代码，然后打本地包，放到安卓工程中寻找问题。。。

问题已经解决，有以下几个地方需要注意（深坑）：

下面几点在标准基座和自定义基座都没问题，离线打包和云打包会出现问题

建议每天开发完就打一次包，好定位问题，像我这样一周打一个版本，如果出现打包问题，找问题的时候你会哭的

1、nvue不支持Vue的全局Filter，main.js中有引入过一个定义全局filter的js文件，里面的filter并没有生效。之前是知道不支持的，但是我项目中依然保留着这个引用，没有及时删除，云打包会导致整个APP页面白屏。

2、在class上动态绑定的时候，请不要使用:class="${getValue(data)}"这种语法，getValue是一个自己定义的方法。

3、引入过一个第三方库query-string，目测云打包不支持。

4、v-else慎用

我之前也遇到过这个问题，后来发现编译器版本升级了，我有的页面没有script标签导致调试可以，打包出来之后除了tabbar都是空白

appid发一下

在Andrio Studio中启动报错日志如下，求安卓大佬帮忙看看

Android Studio运行报错日志

我也遇到了同样的情况，如果是第一次安装app不会白屏，但已经安装了旧版本的情况下，再升级到最新版本，就会白屏。

兄弟，我项目开发完，昨天去打包，但是打开一直全部都是白屏，我的tabbar都没有，我自己封装的，没有用官方的，现在是没有任何报错，测试也正常，云打包就是报错，你是怎么解决的，明天要上第一版了

我是每天打包一次的，然后还是出现这个问题了。
不知道是不是模拟器版本的问题，用了夜神模拟器运行出现白屏，用手机真机、逍遥模拟器没出现问题，找不到问题所在了，看到你发的，我还是有点不懂，我现在慌得一批

Hbuilder版本: 2.7.9.20200527
测试机：小米，华为，iphone7，iphone11

遇到楼主同样的问题，云打包编译正常，正常安装，打开后页面是白屏。

求助。我打包也这样。。。tabbar用官方的昨天还能打包今天就不行了。。
