我在此处遵循说明来构建一个开源Android项目（AOSP-2.3.X）。在我完成了以下内容的构建之后：
. build/envsetup.sh
lunch aosp_arm-eng
make -j16
emulator
我可以看到黑屏模拟器和两条警告消息：
Could not automatically detect an ADB binary.
Some emulator functionality will not work until a custom path to ADB
is added in the extended settings page.
Running an x86 based Android Virtual Device (AVD) is 10x faster.
We strongly recommend creating a new AVD.
在我的终端中显示：
emulator: WARNING: system partition size adjusted to match image file (2050 MB > 200 MB)
emulator: WARNING: encryption is off
当我运行adb devices时，它显示：
List of devices attached
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
emulator-5554 offline
模拟器在Anroid Studio中起作用，但在我尝试构建开源Android Project时终端不工作，是否有有关如何解决此问题的建议？
我遇到了这样的问题，请尝试卸载Android电话驱动程序（在删除驱动程序上检查并重新启动PC），然后继续搜索"通用ADB驱动程序"，下载并设置它，为我工作，也希望你！
