运行AOSP测试

Question

我正在尝试运行一些AOSP测试，但除了cts之外，我不能运行任何测试。我提到过我正试图用一个模拟器来做这件事。这是我的终端的输出：

manuel@banstyle:~/aosp/development/testrunner$ ./runtest.py -v core
Building tests...

有人能帮上忙吗？

Answer 1

当我尝试4.2.2时也遇到了同样的问题。然而，当我在4.3上工作时，我没有这个问题。在谷歌之后，我意识到这个问题是由apk和odex引起的。在4.2.2中，测试被编译成apk和odex，这意味着apk不包含classes.dex。odex文件包含所有类。当你只使用adb install apk时，这实际上会导致失败，因为pm找不到classes.dex。

解决这个问题的方法是在Android.mk中添加LOCAL_DEX_PREOPT := false。这将使dex返回到apk。我已经在4.2.2 full-eng中尝试过了。
