emulator启动编译源码

一、下载SDK，并解压到指定目录。

如/home/zhangyafei/Android/Sdk

二、设置环境路径

echo export ANDROID_HOME="/home/zhangyafei/Android/Sdk" >> ~/.bashrc

echo export PATH="$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools" >> ~/.bashrc

source ~/.bashrc

三、创建虚拟机

android create avd -n android-27 -k "android-27"

-n : 虚拟机的名字

-k 版本。不知道填什么没关系，先随便填一个，出错后会在后面提示。如:

System-Product-Name:~$ android create avd -n android-27 -k  "android-27"*************************************************************************The "android" command is deprecated.For manual SDK, AVD, and project management, please use Android Studio.For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager*************************************************************************Running /home/zhangyafei/Android/Sdk/tools/bin/avdmanager create avd -n android-27 -k android-27Error: Package path is not valid. Valid system image paths are:ository...       system-images;android-26;google_apis;x86null

然后按提示改成正确的。

System-Product-Name:~$ android create avd -n android-26-1 -k  "system-images;android-26;google_apis;x86"*************************************************************************The "android" command is deprecated.For manual SDK, AVD, and project management, please use Android Studio.For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager*************************************************************************Running /home/zhangyafei/Android/Sdk/tools/bin/avdmanager create avd -n android-26-1 -k system-images;android-26;google_apis;x86Auto-selecting single ABI x86===========] 100% Fetch remote repository...       Do you wish to create a custom hardware profile? [no]

四、运行虚拟机：

emulator -avd android-26-1

运行后报错：

System-Product-Name:~$ emulator -avd android-26-1[140422558766912]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at ../emulator/lib64/qt/libCould not launch '/home/zhangyafei/../emulator/qemu/linux-x86_64/qemu-system-i386': No such file or directory

解决方法：

在Sdk/emulator路径下运行命令，当然也可修改PATH

System-Product-Name:/$ cd ~/Android/Sdk/emulator/

再报错：

System-Product-Name:~/Android/Sdk/emulator$ emulator -avd android-26-1ioctl(KVM_CREATE_VM) failed: 16 Device or resource busyqemu-system-i386: failed to initialize KVM: Device or resource busy

原因：

AVD不能与virtualbox同时运行。

解决方法：关闭virtualbox

再运行：

System-Product-Name:~/Android/Sdk/emulator$ emulator -avd android-26-1emulator: INFO: boot completed

运行成功！

五、加载自己编译的源码镜像：

./emulator -avd mydroid -system ANDROIID_DIR/out/target/product/generic/system.img  -data ANDROIID_DIR/out/target/product/generic/userdata.img -ramdisk ANDROIID_DIR/out/target/product/generic/ramdisk.img  -kernel ANDROIID_DIR/prebuilt/android-arm/kernel/kernel-qemu-armv7
