我正在嘗試使用測試apk文件在第三方apk文件上運行espresso黑盒測試。我已經在build.gradle中設置了testApplicationId，並在AndroidManifest.xml中設置了targetPackage。adb shell我的儀器進程崩潰了
這裏是我的命令運行：
adb install app-debug.apk
Success
adb install app-debug-androidTest.apk
Success
adb shell am instrument -w com.example.android.testing.espresso.WikipediaTester/android.support.test.runner.AndroidJUnitRunner
INSTRUMENTATION_RESULT: shortMsg=Process crashed.
INSTRUMENTATION_CODE: 0
這裏的tomcat的日誌：
