错误：清单合并失败并出现多个错误，请参阅日志| 但是在日志中没有错误

Question

我为Android构建我的React Native应用程序时出现以下错误（在iOS上没有问题）。

错误：清单合并失败，出现多个错误，请参阅日志

当我在发布模式下构建时，这会导致真正的问题（调试中的应用程序没有问题），因为它为我的发布版本生成以下Manifest文件：

AndroidManifest.xml（在app / src / release /中）

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myAppName"
    xmlns:tools="http://schemas.android.com/tools">

    <uses-permission tools:node="remove" android:name="android.permission.SYSTEM_ALERT_WINDOW" />
</manifest>

我知道有很多关于这方面的问题，但它们在我的案例中并没有真正帮助，因为如果我按照这个答案中的说法（ https://stackoverflow.com/a/42023614/1432355 ）并转到Merged Manfiest tab我的AndroidManifest.xml文件上的Merged Manfiest tab我没有看到任何错误：

以下是我的manfiest和gradle文件 ：

我的问题与我的代码或gradle设置无关，而是与Android Studio本身有关。

我发现（有很多帮助）在首选项（cmd +，）中有一个名为Experimental的部分，并且在那里有一个名为Only sync the active variant已选中Only sync the active variant的选项。 一旦我取消选中它就会出现错误。
