命令如下：
java -jar signApk.jar platform.x509.pem platform.pk8 shared.x509.pem shared.pk8 media.x509.pem media.pk8 terminal-release.apk terminal-release-sign.apk
生成 terminal-release-sign.apk
其中，signApk.jar/platform.x509.pem/platform.pk8/shared.x509.pem/shared.pk8/media.x509.pem/media.pk8是系統廠商提供的證書相關檔案。
