userdebug和user版本的区别

userdebug和user版本的区别

eng、user、userdebug的区别如下：
1、当make eng时，也即相当于make。此时BuildType为eng，那么其编译进去的内容包括：
·Intended for platform-level debugging
·Installs modules tagged with: eng, debug, user, and/or development
·Installs non-APK modules that have no tags specified
·Installs APKs according to the product definition files, in addition to taggedAPKs
·Sets ro.secure=1
·Sets ro.debuggable=0
·Sets ro.kernel.android.checkjni=1
·adbd is enabled by default
2、当make user时，此时BuildType为user,那么其编译进去的内容包括：
·Intended to be the final release
·Installs modules tagged as user
·Installs non-APK modules that have no tags specified
·Installs APKs according to the product definition files (tags are ignored forAPK modules)
·Sets ro.secure=1
·Sets ro.debuggable=0
·adbd is disabled by default
3、当make userdebug时，此时BuildType为userdebug,那么其编译进去的内容包括：
thesame as user, except:
·Intended for limited debugging
·Installs modules tagged with debug
·Sets ro.debuggable=1
·adbd is enabled by default
