 java -jar signapk.jar platform.pk8 platform.x509.pem test.apk test_sign.apk 

例如出现如下错误:

解决方案

1.将prebuilts/sdk/tools/linux/lib64/libconscrypt_openjdk_jni.so  拷贝到 build/target/prodect/security/

2 签名方法

java -jar -Djava.library.path=. signapk.jar platform.x509.pem platform.pk8 test.apk signed-test.apk
