问题出现的环境背景及自己尝试过哪些方法

检查过xml文件，文件引入没有问题，相应的权限配置也配了的。

你期待的结果是什么？实际看到的错误信息又是什么？

Answer 1

导致这个问题的主要原因是0.60之后加入的jsc和Hermes，有2个解决方案
一、用0.59以下的低版本
二、添加jsc和Hermes配置
1.在Application的onCreat添加

SoLoader.init(this, false)

2.在build.gradle文件中添加以下配置

def jscFlavor = 'org.webkit:android-jsc:+'
project.ext.react = [
        entryFile: "index.js",
        enableHermes: false,  // clean and rebuild if changing
]
def enableHermes = project.ext.react.get("enableHermes", false)
dependencies {
    if (enableHermes) {
            def hermesPath = "../../node_modules/hermes-engine/android/"
            debugImplementation files(hermesPath + "hermes-debug.aar")
            releaseImplementation files(hermesPath + "hermes-release.aar")
        } else {
            implementation jscFlavor
        }
}

3.Sync now
4.enableHermes = true
5.clean and rebuild
