我正在针对模拟器上的应用程序运行espresso测试套件。我看到以下logcat输出出现随机崩溃：

这些崩溃是随机发生的，收集了约300个测试用例。 附加部分我认为可能相关的app build.gradle文件。 （此外，在我将gradle从“ 2.1.2”迁移到“ 3.1.1”之后，这些崩溃已经开始出现）。还添加了项目依赖项。

问题是测试机上的API 23 Intel Atom x86模拟器（可追溯到很久以前），当我将其替换为API 23 Google API x86模拟器“并且”将系统目录指向最新SDK（ 27.1）到目前为止，我再也没有看到该错误。
${SDK_DIR}/tools/emulator -no-boot-anim -sysdir /Users/jenkins/build_tools/android-sdk-27.1/system-images/android-23/google_apis/x86_64 -avd Nexus_9_API_23 > /dev/null 2>&1 &

感谢您提出我的要求。
这可能无关紧要，但由于不建议使用compile关键字，因此应使用“实现”而不是“编译”。您也应该使用“ androidTestImplementation”。这些可能会导致与Gradle 3发生某些冲突吗？可能不会。不过，可能值得一试。
尝试将其添加到app：gradle内
android {
...
testOptions {
unitTests.all {
// All the usual Gradle options.
jvmArgs('-ea', '-noverify')
}
unitTests {
returnDefaultValues = true
}
}
...
}
最后，尝试清理并重建您的项目。您还可以尝试在编译时手动删除Android Studio创建的文件夹，但是如果您不知道自己在做什么，可能会有些冒险。我的流程虽然是这样，但是可能有些旧的，无用的东西会与您现在的东西产生冲突。
