In order to upload your compiled Android file (apk) you need to sign and algin it. There are several ways to do that, but the easiest is to use the tool APK Signer from Hai Bison.

  • JRE 1.6+
  • ADT (including zipalgin file)

You can download the needed Java JDK’s and JRE here.

Just to let you know...

It’s recommended to create the keystore file wiht JDK6 (1.6). If you face any installation issues, try to use JDK6.

Create a keystore file

The tool makes it very easy to create your keystore file. This file can be used for all your games. There is no need to create a new one for each app/game.

Just to let you know...

Note: Save the information used to create the file! Especially the alias and the two passwords! Also save the keystore file and make backups of it!


  • (1) – Locate your Java JDK 1.6 installation path (Java/bin/…)
  • (2) – Update the information for the keystore file (save your password, you’ll need it every time you want to sign your app!)
  • (3) – Click ‘Save as …’ and save the path you want to create the keystore file


  • (4) – Click ‘Generate Keyfile’

If you have added all information and the generation was successfully you will get this notification.


Sign your App

Here you find a simple video showing the steps below.

Switch to the ‘Signer’ tab and make sure the path to your JDK 1.6 installation is set.


  • (1) – Load your keyfile and enter your two passwords (Hint: if you enter the ‘Password’ press the tabulator key. If you password was right the Alias will be set automatically)


  • (2) – Load your app you want to sign (make sure that you have unchecked ‘Sign’ at Intel XDK, otherwise the apk is debug-signed already)


Press ‘sign’ to sign your app. You will get a file named ‘…SINGED_UNALIGNED.apk’

Align your app

Now go to the ‘APK Alignment’ tab and load the apk you got after the signing.


  • (1) – Load your signed app file


Press ‘align’ and you will get a file named ‘…SIGNED_ALIGNED.apk’. This file is ready to be uploaded to the Google Play Store.

Issues & Troubleshooting

APK Signer doesn’t start

If you are facing the issue, that the APK Signer tool freezes at startup (only the logo is shown), please go to following steps.

  • Remove all newer Java RE’s and JDK’s than 8
  • Maybe restart your computer
  • Install Java RE & JDK8
  • Run again

You also find a video solution guide below.

File.IO Error

If you keep getting the error message that the tool cannot find the jarsigner.exe, please download the latest JDK here.

And specifiy the path at the APK Signer.
