Android笔记-CTS

        为了保证开发的应用在所有兼容Android的设备上正常运行，并保证一致的用户体验，Google制定了CTS（Compatibility Test Suite）来确保设备运行的Android系统全面兼容Android规范，Google也提供了一份兼容性标准文档（Compatibility Definition Document, CDD）。

1，制作release-key

        CTS有个测试项testPackageSignatures ，该测试项会使用google default key里check是否使用的是google default key，如果是，则会test fail。 因此要使用和google default不一样的key。release key不仅可以满足CTS request，还可以满足工信部CATR TAF spec。

1，Genernate the release key

        –development/tools/make_key releasekey       '/C=CN/ST=BeiJing/L=HaiDian/O=MediaTek/OU=WCD/CN=demo/emailAddress=demo@mediatek.com'

 2,  Genernate the platform /media/shared key，the method as follows：

        Generate platform keys：
        development/tools/make_key platform               '/C=CN/ST=BeiJing/L=HaiDian/O=MediaTek/OU=WCD/CN=demo/emailAddress=demo@mediatek.com'
       Generate media keys
       development/tools/make_key media '/C=CN/ST=BeiJing/L=HaiDian/O=MediaTek/OU=WCD/CN=demo/emailAddress=demo@mediatek.com'
       Generate shared keys
       development/tools/make_key shared '/C=CN/ST=BeiJing/L=HaiDian/O=MediaTek/OU=WCD/CN=demo/emailAddress=demo@mediatek.com'

    3, get the test key from build/target/product/security/

    4,  Move testkey.pk8, testkey.x509.pem,releasekey.pk8, releasekey.x509.pem, media.pk8, media.x509.pem, platform.pk8, platform.x509.pem, shared.pk8 and shared.x509.pem to device/mediatek/common/security/${Project} 

    5,  Set MTK_SIGNATURE_CUSTOMIZATION = yes and MTK_INTERNAL = no in the ProjectConfig.mk. 

    6,  Start a normal build, and the binary-released APK will be signed automatically.
