android - 运行 AOSP 测试

Question

我正在尝试运行一些 AOSP 测试，但我无法运行除 cts 之外的任何测试。我提到我正在尝试使用模拟器来做到这一点。这是我终端的输出:

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

有人能帮忙吗？

Answer 1

我在尝试 4.2.2 时也遇到了同样的问题。但是，我在 4.3 上工作时没有问题。谷歌搜索后，我意识到问题是由apk和odex引起的。在 4.2.2 中，测试被编译成 apk 和 odex，也就是说，apk 中不包含 classes.dex。 odex 文件包含所有类。当您仅“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。这会将 dex 放回 apk。我在 4.2.2 full-eng 中尝试过这个。
