我试着改变compilesdk和mindsdk的版本，就像here告诉我的那样。我读了所有其他关于同样的帖子，但是到目前为止没有一个成功。我看了以前的答案ans1和ans2。他们没有帮助。
当我试图运行这个项目时，它会引发多个错误。我认为主要的问题是因为这个
找不到任何符合org.jitsi.react：jitsi-meet-sdk：3.+的项目，因为没有可用的org.jitsi.react：jitsi-meet-sdk版本。

build.gradle（我的应用程序）

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
        maven {
            url "https://github.com/jitsi/jitsi-maven-repository/raw/master/releases"
        }
    }

    dependencies {
        classpath "com.android.tools.build:gradle:7.0.4"
        classpath 'com.google.gms:google-services:4.3.10'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

构建.gradle（应用程序）

}

任何帮助都是感激不尽的。
