there is a lot of talk on the web about adding a configuration to gradle.properties, but the addition is not solved.

solution: the compiled version is not configured correctly. Original version number: 

android {
    //
    compileSdkVersion 24

    buildToolsVersion '28.0.3'

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 24

    }
...

after modification: 

android {
    // 
    compileSdkVersion 28

    buildToolsVersion '28.0.3'

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 28

    }

compiles again, and the problem is resolved. This is the solution I came across, others are not met for the time being.
