我们知道在Windows系统下阅读源码利器是Source Insight,但是没有Mac版本,阅读源码一直是个问题,之前我写过关于阅读源码神器的Understand,但是如果项目过大则很慢,所以也不能用来阅读Android系统源码,在网上也查过Sublime text配置ctag,但是相对来说也是不方便,后来使用Visual Studio Code和Sublime text相差不多,最后想到用IntelliJ IDEA来阅读源码,如果直接导入则会分为很多module。最近从网上看到可以导入IntelliJ IDEA软件,所以给大家分享一下。本教程基于Mac OS X 10.12。Android系统版本为:7.1.2_r11(7.1.2最终版)。先介绍方法,后面会给出各种问题解决方案。
生成导入idea或者eclipse需要的文件:
- 1.首先是idea和eclipse导入项目需要的文件
.classpath (Eclipse)
android.ipr (IntelliJ / Android Studio)
android.iml (IntelliJ / Android Studio)
- 2.修改MacOS sdk 版本:
路径Android-7.1.2_r11/build/core/combo/mac_version.mk,加上你现在系统的版本:
mac_sdk_versions_supported := 10.8 10.9 10.10 10.11 10.12
- 3.生成idegen.jar过程:
命令:
$ source build/envsetup.sh
执行结果:
including device/asus/fugu/vendorsetup.sh
including device/generic/mini-emulator-arm64/vendorsetup.sh
including device/generic/mini-emulator-armv7-a-neon/vendorsetup.sh
including device/generic/mini-emulator-mips/vendorsetup.sh
including device/generic/mini-emulator-mips64/vendorsetup.sh
including device/generic/mini-emulator-x86/vendorsetup.sh
including device/generic/mini-emulator-x86_64/vendorsetup.sh
including device/google/dragon/vendorsetup.sh
including device/google/marlin/vendorsetup.sh
including device/htc/flounder/vendorsetup.sh
including device/huawei/angler/vendorsetup.sh
including device/lge/bullhead/vendorsetup.sh
including device/linaro/hikey/vendorsetup.sh
including device/moto/shamu/vendorsetup.sh
including sdk/bash_completion/adb.bash
命令:
$ mmm development/tools/idegen
执行结果:
...
date: 1496452336: No such file or directory
Starting build with ninja
ninja: Entering directory `.'
[ 25% 1/4] host Java: idegen (out/host/com...VA_LIBRARIES/idegen_intermediates/classes)
注: 某些输入文件使用或覆盖了已过时的 API。
注: 有关详细信息, 请使用 -Xlint:deprecation 重新编译。
[100% 4/4] Install: out/host/darwin-x86/framework/idegen.jar
#### make completed successfully (18 seconds) ####
命令:
$ development/tools/idegen/idegen.sh
执行结果:
bash-3.2$ development/tools/idegen/idegen.sh
Read excludes: 4ms
Traversed tree: 44148ms
此时会在根目录生成两个文件:android.ipr和android.iml,然后打开idea软件,执行下面操作:
接着打开如下界面,找到Android源码位置,然后找到生成的android.iml文件,鼠标选中,然后点击open即可。
注:mmm命令要先执行第一条命令。
生成文件出现的问题:
- 1.在执行
$ source build/envsetup.sh
命令时会遇到下面问题:
build/envsetup.sh:630: command not found: complete
WARNING: Only bash is supported, use of other shell would lead to erroneous results
警告需要再bash下执行命令,我用的是zsh,临时切换回bash,直接输入bash:
$ bash
如果不切换回bash输入
$ mmm development/tools/idegen
命令则会报下面错误:
Couldn't locate the directory development/tools/idegen
- 2.由于生成该文件需要MacOS SDK,所以需要安装Xcode,最新版Xcode里面的sdk是10.12(与最新系统一样),而在Android源码里面最高到10.11,所以不支持,需要修改源码中的对sdk的支持:
打开路径Android-7.1.2_r11/build/core/combo/mac_version.mk,加上你现在系统的版本:
mac_sdk_versions_supported := 10.8 10.9 10.10 10.11 10.12
其实这个方法也不能解决,因为后面的编译中还是不支持10.12,由于对里面不熟,所以采用了另一个方法,在Xcode中添加sdk,见下面方法。
- 3.问题:不支持Mac OS X 10.12,添加sdk
system/core/libcutils/threads.c:38:10: error: 'syscall' is deprecated: first deprecated in OS X 10.12 - syscall(2) is unsupported; please switch to a supported interface. For SYS_kdebug_trace use kdebug_signpost(). [-Werror,-Wdeprecated-declarations]
return syscall(SYS_thread_selfid);
^
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/unistd.h:733:6: note: 'syscall' has been explicitly marked deprecated here
int syscall(int, ...);
^
1 error generated.
ninja: build stopped: subcommand failed.
make: *** [ninja_wrapper] Error 1
解决办法:
Here is how I fixed it:
Download earlier Mac OSX SDK(10.11 worked for me) from
https://github.com/phracker/MacOSX-SDKs/releases
Unzip and copy to /Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

- 4.Mac默认系统不区分大小问题:
报错:
Checking build tools versions...
build/core/main.mk:90: ************************************************************
build/core/main.mk:91: You are building on a case-insensitive filesystem.
build/core/main.mk:92: Please move your source tree to a case-sensitive filesystem.
build/core/main.mk:93: ************************************************************
build/core/main.mk:94: *** Case-insensitive filesystems not supported. Stop.
此时你可以建一个磁盘镜像,步骤如下:
打开磁盘工具-->文件-->新建映像-->空白映像-->弹出如下界面,填写下面框内的信息,格式选择区分大小写格式,点击存储,然后会在你的位置文件夹内生成一个Android.dmg文件,双击即可安装,然后将Android源码考入即可操作。
