在ASOP源码中对apk使用以下命令进行签名时
java -Xms512m -jar signapk.jar -w platform.x509.pem platform.pk8 to_be_signed.apk demo_Signed.apk
会出现报错提示：

原因是缺少参数：-Djava.library.path，加上该参数
java -Xmx512m -Djava.library.path=./prebuilts/sdk/tools/linux/lib64/ -jar signapk.jar -w platform.x509.pem platform.pk8 tobe_signed.apk demo_Signed.apk
