Ionic Framework Tutorial 13: Signing APK

Learn how to sign your unsigned android APK to make sure that your apk works on your android device.

[vishalbalani]

one thing to mention which is not mentioned is you need to cd to java/jdk/bin folder and then run this command having relative path for APK...I am not sure how in all videos jarsigner is called from some random path

Hi. when I ran keystore command on project path, nothing happened and also there was no error. Could you please help.

[ryanarcher]

Thanks alot for this video! The ionic documentation does not make mention of the keystore file and the release apk file being in the same directory and I kept getting error `jarsigner: unable to open jar file: app-release-unsigned.apk`. It makes SO MUCH sense now. Would just be nice if Ionic made a note about that in their documentation.

The JKS keystore uses a proprietary format. It is recommended to migrate to PCKS 12 which is an industry santdard fromat using "keytool -importkeystore -srckeystore my-relase-key.keystore -destkeystore my-release-key.keystore -deststoretype pkcs12".

Hi! My JDK doesn't have a jarsigner! I have looked for it and it's not there. The keytool is there but not the jarsigner. What to do? I have already tried reinstalling so that's not the problem. Is the new version of JDK without jarsigner or something? Please help!
