下面是我执行前的环境配置,给需要的同学个参考:
1\使用 eclipse 导入工程:imports as android project;
2\更改 project build target 为 7.1.1;
3\更改 jdk complier compliance level 为 1.7(本地的 java -version 为 1.8);
4\处理些报错提示,主要是添加 final;
5\manifest 里面替换被测应用包名;
6\Iteration.java 文件中,填写 LAUNCHER_ACTIVITY 和 homeActivity,登录相关的因为用不到用" "代替,其他用不到部分清空;
7\因为项目没有登录页面,屏蔽 test_00_login 的代码;
8\被测项目用的 v4 版本更新,更新 support-v4-23.3.0(删除自带的 support-v4 后通过 android tools 的 add support library 更新);
9\安装后使用命令执行测试:adb shell am instrument -w -r -w -e debug false -e class application.iteration.Iteration#test_01_iteration 被测应用包名.test/com.heyniu.auto.InstrumentationTestRunner
使用 eclipse 直接执行会报 Process crashed

弄了好些时间还是跑不起来,测试启动后被测应用界面闪了下后报错:Test run failed: Instrumentation run failed due to 'java.lang.NullPointerException'
logcat 的日志是:

请问是哪里出问题了?对 robotium 不熟悉..
