Please follow these instructions to install the Javelin3 for Android app on your Android phone or tablet. Javelin3 is the preferred choice for all recent versions of Android. Note: You can also use this procedure for Amazon Kindle Fire devices and similar "special/non-standard" Android variants and devices (Chromebooks with Android/PLAY support should use the Google Play store) - in some cases this will work OK but no guarantees! Use the Play version, "Javelin3 PDF reader" if you have Google Play access on your device. In general we strongly recommend using a fully supported device with the latest versions of the Javelin PDF readers

1 Confirm Your Device Allows Direct Installation of the Javelin3/Javelin readers

Open the Settings facility on your device and navigate to Unknown sources option (this can be found under Biometrics and security, OR Lock screen and Security, OR Applications or Security depending on your device and Android version - see image below for an example)

Android settings

If Unknown sources is already checked/ON, you can skip this step.

If unchecked, tap the checkbox and then tap OK on the confirmation popup or set or the option button to ON.

2 Download the Javelin3 reader to your Android phone or tablet from the link below

From your Android phone or tablet visit (Android 5 to 13):

https://www.drumlinsecurity.com/kits/android/Javelin3_3.00.80.apk

to download Javelin3 for Android

From your Android phone or tablet visit (Android 7 or less - if necessary):

https://www.drumlinsecurity.com/kits/android/Javelin_1.01.06.apk

to download the old Javelin for Android program

3 Install the reader

When the download is complete, if it has been downloaded from your Android device, open your notifications or your Downloads folder and tap the apk file (e.g. Javelin3_3.00.80.apk or Javelin_1.01.06.apk) as appropriate. Then:

  • Tap Install
  • Tap Open
  • That’s it!

On recent versions of Android, when you first run Javelin3, you may be asked to "allow access to your local file system" - please click the "OK" button (Javelin3 need to be able to open PDF and DRM files on your device). You may then be prompted to "Allow Javelin3 to access photos, videos, music and audio on this device?" - please click the "Allow" button (again, this is to allow Javelin3 access to PDF and DRM files).
