2.遡及ソースコードを比較した場合、r 8はcrashしません.r 8ツールはr 11ツールのコードと異なり、getHistoryCollection()を呼び出す関数が追加されました.
camera/its/ItsTestActivity.java +347
342 if (mToBeTestedCameraIds.size() == 0) {
343 showToast(R.string.all_exempted_devices);
344 ItsTestActivity.this.getReportLog().setSummary(
345 "PASS: all cameras on this device are exempted from ITS"
346 , 1.0, ResultType.NEUTRAL, ResultUnit.NONE);// pass。crash ， ， apk 。
347 setTestResultAndFinish(true);//

以上の294のように、apkをテストするコードに問題があるため、空のポインタが異常crashになりました.
