所以我在android上启动初始react-native模板项目时遇到了一些问题。在咨询某人后，我被告知jdk 17不支持。但我真的不想降级，因为这可能会破坏我已经使用的其他东西。具体来说，这是我得到的错误：

我已经看过这个了，没有任何效果。Gradle: Execution failed for task ':processDebugManifest'

要知道这是否是Java版本相关的问题，您需要检查您的Gradle版本。
目前只有Gradle 7.3版本支持Java 17。
你可以检查gradle compatibility matrix来检查。
你可以用命令行输入
gradlew.bat -version来检查你的版本如果你的Gradle是7.3版本，那么它与JDK版本无关。

所以我通过在我的系统上安装JDK 16解决了这个问题，一切都解决了，运行正常。我不知道这个问题是Gradle还是JDK还是react-native，但希望将来支持jdk 17。
如果你有同样的问题，那么你可以去：jdk 16
1)下载并安装JDK 16。
2)在系统环境变量的PATH中添加jdk的路径。
3)打开cmd并执行
java -version，您应该看到类似于字符串

对我来说，react native没有成功地与OpenJdk 17一起工作。
安装OpenJDK 11后，这个问题得到了解决。
