### 【问题描述】 工具:Cts-Verifier-9.0-R11.apk 测试Camera ITS Test时,点击该测试项后verifier apk闪退。重新打开后该项未pass变绿。 ### 【问题结论】 ###AuthBlog:秋城[https://www.cnblogs.com/houser0323](https://www.cnblogs.com/houser0323) 最新结论:是waiver项。 拿到了Google-waiver id:[http://partnerissuetracker.corp.google.com/issues/150153190](http://partnerissuetracker.corp.google.com/issues/150153190) 怀疑verifier工具问题 r8工具没问题,r11有问题。 r11工具在送测成功的盒子也有问题。 ### 【分析详细】 **1.crash日志:** ```shell 03-04 14:34:36.977 8091 8091 D AndroidRuntime: Shutting down VM --------- beginning of crash 03-04 14:34:36.987 8091 8091 E AndroidRuntime: FATAL EXCEPTION: main 03-04 14:34:36.987 8091 8091 E AndroidRuntime: Process: com.android.cts.verifier, PID: 8091 03-04 14:34:36.987 8091 8091 E AndroidRuntime: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.android.cts.verifier/com.android.cts.verifier.camera.its.ItsTestActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'int com.android.cts.verifier.TestListAdapter.getCount()' on a null object reference 。。。。。。 03-04 14:34:36.987 8091 8091 E AndroidRuntime: Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int com.android.cts.verifier.TestListAdapter.getCount()' on a null object reference 03-04 14:34:36.987 8091 8091 E AndroidRuntime: at com.android.cts.verifier.PassFailButtons$TestListActivity.getHistoryCollection(PassFailButtons.java:294) 03-04 14:34:36.987 8091 8091 E AndroidRuntime: at com.android.cts.verifier.PassFailButtons$TestListActivity.setTestResultAndFinish(PassFailButtons.java:282) 03-04 14:34:36.987 8091 8091 E AndroidRuntime: at com.android.cts.verifier.camera.its.ItsTestActivity.onCreate(ItsTestActivity.java:347) 03-04 14:34:36.987 8091 8091 E AndroidRuntime: at android.app.Activity.performCreate(Activity.java:7144) 03-04 14:34:36.987 8091 8091 E AndroidRuntime: at android.app.Activity.performCreate(Activity.java:7135) 03-04 14:34:36.987 8091 8091 E AndroidRuntime: at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1271) 03-04 14:34:36.987 8091 8091 E AndroidRuntime: at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2894) 03-04 14:34:36.987 8091 8091 E AndroidRuntime: ... 11 more 03-04 14:34:37.000 3184 4971 W ActivityManager: Force finishing activity com.android.cts.verifier/.camera.its.ItsTestActivity 03-04 14:34:37.003 3184 4971 W ActivityManager: Force finishing activity com.android.cts.verifier/.CtsVerifierActivity 03-04 14:34:37.009 2988 3123 W libc : Unable to set property "sys.vsync.type" to "": error code: 0x18 03-04 14:34:37.010 8091 8091 I Process : Sending signal.
