Question

当我们将android项目升级到java8时，connectedAndroidTest停止在Kitkat设备上运行Robotium测试。但是相同的代码在Lollipop和更高的Android版本上运行良好，甚至在kitkat上运行时从Android Studio执行时运行正常。但是一旦我们切换到./gradlew cAT，它就会停止在具有以下日志的kitkat设备上执行：

如果使用AndroidJUnitRunner执行执行，则会显示以下错误：

18:29:56.902 [LIFECYCLE] [org.gradle.api.Task] Starting 0 tests on Titanium Octane Plus - 4.4.2 18:29:56.903 [WARN] [org.gradle.api.Task] Tests on Titanium Octane Plus - 4.4.2 failed: Instrumentation run failed due to 'java.lang.IllegalAccessError' 18:29:56.939 [INFO] [org.gradle.api.Task] [XmlResultReporter]: XML test result file generated at /Users/sil/Workspace/Android/LrAndroid/dev-eng/Thio/android/build/outputs/androidTest-results/connected/TEST-Titanium Octane Plus - 4.4.2-android-.xml.

This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test annotations).

但如果使用了orchestrator，则会显示以下日志：

build.gradle中使用java8所做的更改是：

compileOptions { targetCompatibility JavaVersion.VERSION_1_8 sourceCompatibility JavaVersion.VERSION_1_8 }

期待解决为什么问题仅在Kitkat和较低设备上发生的解决方法/解释（尽管我对Android版本低于kitkat的设备并不感到烦恼）。

Answer 1

问题是由于未在build.gradle中定义用于测试代码的Java源目录。所以以前的代码就像

instrumentTest.setRoot('tests')

或

androidTest.setRoot('tests')

将其更新为以下内容即可解决问题。

androidTest {
        setRoot('tests')
        java.srcDirs = ['src/androidTest/java']
        manifest.srcFile file('src/androidTest/AndroidManifest.xml')
    }

将compileOptions升级到java8会导致connectedDebugAndroidTest无法在Kitkat设备上运行
