Hi ,

Good day.

I need to sign app with this command for my android pos device:

B4X:
java -jar signapk.jar platform.x509.pem platform.pk8  [unsigned.apk]  [signed.apk]
but I can not find signapk.jar , platform.x509.pem , platform.pk8

(unsigned.apk = B4A APP)

Regards,
PMT

Where does this line come from?
This is from android pos sdk manual in the signature apk file step.
I need to
1.include android:shareUserId="android.uid.system" in Androidmanifest
2.use signature tools to sign apk file
java -jar signapk.jar platform.x509.pem platform.pk8 unsigned.apk signed.apk
(*unsigned.apk = my unsigned app)

I create b4a library from android pos sdk and use in my b4a app.
My android pos device is android 5.1.1

You should use B4ABuilder to build an unsigned APK.

The other three files: signapk.jar platform.x509.pem platform.pk8, should be provided to you by the device manufacturer.
Thank you , I will try.
