我最近将反应本机从0.55.4升级到0.59.2。我正在使用wix v1.1.486的本地导航。由于库中的一些函数抛出错误，我决定转向v2。我能够在ios上以完美的方式运行app并在调试模式下运行android。
但是，当我试图生成一个签名的apk时，我面临着“无法从资产中加载脚本'index.android.bundle”问题，并且能够修复它(reference)
现在我被困在闪屏上。该应用程序不会进一步移动。
验证它在调试模式下工作。尝试使用空的主要活动所以没有问题。该项目使用redux，我在android studio中看到了最初的redux日志。尝试在模拟器和设备上运行。还反应本机run-android --variant = release有效。

从./gradlew assembleRelease生成签名的apk卡在启动画面/启动画面上。
如果你的应用程序停留在启动画面，可能会隐藏一些错误，通常是在js包中。使用adb logcat *:E查看android的错误日志，你可能会更好地处理出错的地方
