Android.mk

使…如果做平台app开发需要签platform签名除了通过adroid.bp或者android.mk的方式使用AOSP整个大工程中签名外还可以直接通过signapk.jar的方式进行签名效率更高更快捷简便。

Android.mk

使用LOCAL_CERTIFICATE宏定义值为platform。

以上两种方式需要进行前期整个编译系统工具链的编译准备工作如果我们仅仅是为了快速签名编码工作放置在Android

准备工作

我们只需要从在研Android工程中取得签名私钥和公钥进行签名。

java

公私密钥获取

testkey.x509.pem其中platform.pk8就是我们的私钥platform.x509.pem就是我们的公钥。

其也可以从Android项目工程里边获取到这里以Android
