在Android N中签名使用下面的命令就可以了
java -jar signapk.jar platform.x509.pem platform.pk8 app-debug.apk signed.apk
该命令在Android O中会报错。具体错误如下。

错误原因是conscrypt_openjdk_jni-windows-x86_64, conscrypt_openjdk_jni
。,也就是conscrypt_openjdk_jni
。
这里需要libconscrypt_openjdk_jni.so。
libconscrypt_openjdk_jni.so 在源码中存在于2个地方:
1.out/host/linux-x86/lib64
2.prebuilts/sdk/tools/linux/lib64
我这里用的是out/host/linux-x86/lib64下的libconscrypt_openjdk_jni.so 文件,如果1路径下的报错就用2路径下的,大家用的都不一样。
把需要签名的app-debug.apk
,signapk.jar
, platform.x509.pem
,platform.pk8
,libconscrypt_openjdk_jni.so
,放到同一目录下,例如放到vendor/mediatek/proprietary/packages/apps/xxx
,进入xxx目录下后执行下面的命令即可。
java -Djava.library.path=. -jar signapk.jar platform.x509.pem platform.pk8 app-debug.apk app_sign.apk
