我在运行跟踪项目时遇到了同样的错误(https://github.com/trentpiercy/trace)在我的本地。针对这个具体问题。我更新了gradle版本，这个异常消失了。

在android文件夹下，打开build.gradle并更新渐变版本，如下所示。(注意，该版本最初为3.2.1。我更新到4.2.2，尽管其他更高版本也可以(

dependencies {
classpath 'com.android.tools.build:gradle:4.2.2'
}

然后打开grade/wrapper/下的gradle-wrapper.properties，将distributionUrl更改为6.7.1:版本以上

distributionUrl=https://services.gradle.org/distributions/gradle-6.7.1-all.zip

我还遇到了一些其他问题，包括将androidminSdkVersion升级到28，将targetSdkVersion升级到31；将CCD_ 7设置为CCD_；在AndroidManifest.xml的MainActivity中添加android:exported="true"等
