一种可能的解决方法是在所有模块的 build.gradle 文件中添加以下配置：

android { ...

buildTypes {
    release {
        ...
        testCoverageEnabled true
    }
    debug {
        ...
        testCoverageEnabled true
    }
}

applicationVariants.all {
    variant ->
        if (variant.buildType.name == 'release') {
            variant.getAssemble().doLast {
                applyCoverageReport(variant)
            }
        } else {
            variant.getExtensions()
                    .getExtraProperties()
                    .set('android.testInstrumentationRunnerArguments',
                            android.testInstrumentationRunnerArguments +
                                    ["coverage" : "true"])

            variant.getAssemble().doLast {
                tasks.create(name: "create${variant.name}CoverageReport",
                        type: JacocoReport) {
                    group = "Reporting"
                    description = "Generate Jacoco coverage reports for ${variant.name} build."
                    reports {
                        xml.enabled true
                        html.enabled true
                    }
                    additionalSourceDirs.from(
                                variant.javaCompileProvider.get().getSource().get().srcDirs)
                    sourceDirectories.from(
                                files([configurations.compile]) +
                                files([project.android.sourceSets.main.java.srcDirs]))
                    classDirectories.from(
                                files([variant.javaCompileProvider.get().getDestinationDir()]) +
                                files([configurations.runtimeClasspath]))
                    executionData.from(
                                fileTree(dir: "$buildDir/outputs/code_coverage/${variant.dirName}",
                                        includes: [
                                                "*${"$"}{variant.name}*",
                                                "*coverage.ec"
                                        ]))
                }
            }
        }
}

...

}
