Tiny4412_android5.0.2编译

源码导入android

参考
参考2
1, . setenv
2, lunch (choose 14. full_tiny4412-eng)
3, mmm development/tools/idegen/
4, sh ./development/tools/idegen/idegen.sh
这行命令的意思是生成对应的文件:android.iws, android.ipr, android.iml
生成对应的文件后,打开Android Studio,选择打开一个现有的Android Studio项目,选择Android源码的根目录,导入即可(起作用的是android.irp文件).在配置sdk版本之后就可以查看Android 源码了.

报错:

    Exception in thread "main" java.io.FileNotFoundException: ./out/target/product/hammerhead/obj/GYP/shared_intermediates/res.java (Is a directory)    at java.io.FileInputStream.open(Native Method)    at java.io.FileInputStream.(FileInputStream.java:138)    at java.io.FileReader.(FileReader.java:72)    at Configuration.parsePackageName(Configuration.java:204)    at Configuration.rootOf(Configuration.java:180)    at Configuration.traverse(Configuration.java:140)    at Configuration.traverse(Configuration.java:167)    at Configuration.traverse(Configuration.java:167)    at Configuration.traverse(Configuration.java:167)    at Configuration.traverse(Configuration.java:167)    at Configuration.traverse(Configuration.java:167)    at Configuration.traverse(Configuration.java:167)    at Configuration.traverse(Configuration.java:167)    at Configuration.(Configuration.java:72)    at Main.main(Main.java:37)

解决办法是将

./out/target/product/hammerhead/obj/GYP/shared_intermediates/res.java修改为:./out/target/product/hammerhead/obj/GYP/shared_intermediates/res.j

3, 编译android报错, java版本不对

============================================Checking build tools versions...************************************************************You are attempting to build with the incorrect versionof java. Your version is: openjdk version "1.8.0_181" OpenJDK Runtime Environment (build 1.8.0_181-8u181-b13-1ubuntu0.16.04.1-b13) OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode).The required version is: "1.7.x" Please follow the machine setup instructions at    https://source.android.com/source/initializing.html************************************************************build/core/main.mk:167: *** stop。 停止。#### make failed to build some targets (6 seconds) ####

解决:
切换java版本到openjdk7
sudo update-alternatives --config java
如果且不过来 , 检查一下~/.bashrc是不是配置了固定java_home
如果还是不行 , 退出termial 在进, 最后不行就重启.

4, clang问题

clang: error: linker command failed with exit code 1 (use -v to see invocation)build/core/host_shared_library_internal.mk:44: recipe for target 'out/host/linux-x86/obj32/lib/libnativehelper.so' failedmake: *** [out/host/linux-x86/obj32/lib/libnativehelper.so] Error 1

重新make 不加-j参数 .

external/libcxx/include/thread:149: error: unsupported reloc 43clang: error: linker command failed with exit code 1 (use -v to see invocation)build/core/host_shared_library_internal.mk:44: recipe for target 'out/host/linux-x86/obj32/lib/libc++.so' failedmake: *** [out/host/linux-x86/obj32/lib/libc++.so] Error 1#### make failed to build some targets (04:12 (mm:ss)) ####

从log看都和clang有关,参考
1.修改
cd /art/build/
vim Android.common_build.mk //修改第119行
修改前：

# Host.ART_HOST_CLANG := falseifneq ($(WITHOUT_HOST_CLANG),true)# By default, host builds use clang for better warnings.ART_HOST_CLANG := trueendif修改后：# Host.ART_HOST_CLANG := falseifneq ($(WITHOUT_HOST_CLANG),false)# By default, host builds use clang for better warnings.ART_HOST_CLANG := trueendif

2.修改
经过第一次修改之后发现编译还是报同样的错误，执行下面：
cp /usr/bin/ld.gold /prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld
3.修改过上述代码后，最好执行一次make update-api，再make

5, 报错如下

You have tried to change the API from what has been previously approved.

To make these errors go away, you have two choices:

You can add “@hide” javadoc comments to the methods, etc. listed in the
errors above.
You can update current.txt by executing the following command:
make update-api

To submit the revised current.txt to the main Android repository,
you will need approval.

build/core/tasks/apicheck.mk:57: recipe for target ‘out/target/common/obj/PACKAGING/checkapi-current-timestamp’ failed
make: *** [out/target/common/obj/PACKAGING/checkapi-current-timestamp] Error 38

解决:参考
make update-api
