    Issue:  Android application is crashing periodically across multiple devices


    A possible cause for this is an incorrect version number listed for the software package for your application within Avalanche.


    Example:  Velocity crashes on multiple devices every hour


    If this is a Zebra device you can use Rxlogger to grab logging during the crash.  You will see something similar to below:

    This tells us that when the device checks in every hour as directed by Avalanche, then Velocity is re-installing and this is the cause of the application crashing.


    Check the version of your software package for Velocity within Avalanche against the version located within the manifest.xml file.

    For information on grabbing your version from the manifest.xml go here:  Obtain Android Package ID and Package Version from APK


    As you can see my version number is incomplete.  When the device checks into Avalanche it is expecting to see the full version of  When it checks in and only sees 1.2.112, then Avalanche sees the versions as incompatible and installs to replace with what Avalanche has listed.  Even though the apks are the same, the verification fails against the Package Version.


    Update your package version with the complete and correct version, save your package, deploy and when the device checks in verification will pass.
