我正在尝试使用Android NDK编译Android运行时。首先，我克隆了存储库并切换到marshmallow-cts-release分支。然后在运行ndk-build时我得到了
suici@HP-Pavilion-g7:~/art$ ndk-build
Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.
/usr/local/src/android-sdk-linux_x86/ndk-bundle/build/core/build-local.mk:151: *** Android NDK: Aborting . Stop.
suici@HP-Pavilion-g7:~/art$
我该如何编译？我需要整个Android源代码树吗？或者我做错了什么？
存储库包含Android.mk文件。我在HP Pavilion g7-2269wm上使用基本的OS freya 64位（基于Ubuntu）。安装了最新的SDK和NDK。
在重新克隆ART的来源并通过运行以下内容进行编译之后。
git clone https://android.googlesource.com/platform/art
cd art
git checkout marshmallow-cts-release
export NDK_PROJECT_PATH=$PWD
ndk-build APP_BUILD_SCRIPT=Android.mk
我得到了

我下载了ASOP源代码并为x86_64构建了它。在一个文件夹中，我可以找到public class YourClass ... {
public YourClass() {
throw new Exception("Ha (1)!");
InitializeComponent();
throw new Exception("Ha (2)!");
}
}
二进制文件，这就是我想要的。但我有一个问题。
首先安装所有Android库，我将dalvikvm中的所有内容复制到out/host/linux-x86/lib/并在/usr/bin内翻到out/host/linux-x86/lib64/并运行/usr/bin/x86_64-linux-gnu/和{{1获取所有Android库（64和x86）
执行ldconfig -v -n /usr/lib时，我得到了
ldconfig -v -n /usr/lib/x86_64-linux-gnu/运行./dalvikvm后，通过向其中添加以下行修改art F 6066 6066 art/runtime/utils.cc:1218] ANDROID_ROOT not set and /system does not exist

后，一切似乎都能正常工作。
dalvikvm --32将~/.bashrc替换为AOSP文件夹的路径。然后运行export ANDROID_ROOT=!!!PATH-TO-AOSP!!!/out/debug/host/linux-x86/product/generic_x86_64/system
# configure bootclasspath
export BOOTCLASSPATH=$ANDROID_ROOT/framework/core.jar:$ANDROID_ROOT/framework/ext.jar:$ANDROID_ROOT/framework/framework.jar:$ANDROID_ROOT/framework/android.policy.jar:$ANDROID_ROOT/framework/services.jar
# this is where we create the dalvik-cache directory; make sure it exists
export ANDROID_DATA=/tmp/dalvik_$USER
创建文件夹。
