Part 4 of 5:
Moving the Package to the Android

  1. 1
    Install ZipSigner from the Play Store. This is a free app that you can use to digitally sign the package you created. This is necessary for installing Undertale.
    • ZipSigner is the app with a brown package icon that says ″CERT″ inside.
  2. 2
    Connect your Android to your PC with a USB cable. You can use the cable that came with your Android or one that’s compatible.[4]
    • If your Android’s screen is locked, unlock it once you’ve connected it to the computer.
    • If prompted to choose a method for connecting, select MTP or File Transfer.
  3. 3
    Double-click your Android to display its files. If a window containing your devices didn’t appear automatically, you can click your Android in the left column of the file explorer.
  4. 4
    Navigate to your Android’s Download folder. The location varies by Android, and it may be located on your SD card.
    • If there’s no Download folder, you can create one just as you’ve been doing on your computer.
  5. 5
    Copy UndertaleWrapper.apk from the ″undertalemusic″ folder to your Android’s Download folder. The process is the same as it was when copying files to other folders on your computer:
    • Right-click the file and select Copy.
    • Right-click a blank space in the Download folder and select Paste.
  6. 6
    Open ZipSigner on your Android. This is the app you installed earlier. You should find it in the app drawer.
  7. 7
    Click CHOOSE IN/OUT. A list of folders on your Android will appear.
  8. 8
    Open the Download folder.
  9. 9
    Select UndertaleWrapper.apk.
  10. 10
    Click SIGN THE FILE. This begins the process of signing the file. Be patient, as it may take a while. Once the app returns to the main screen, you’ll know the process is complete.[5]
    • Keep your Android connected to the computer for now.

  12. 12

    • Tap the settings button.

    • Follow the on-screen instructions to complete the import.
