Description Christian.Wall 2016-06-09 06:40:35 UTC
We have a Custom Application Class tagged with the Application Attribute. This class worked fine, means it was instantiated prior to any Activity.
After Upgrading from Cycle 6 to 7 the Class will be ignored.

# Steps to reproduce
1. Create Blank App
2. Add a custom Application Class
  public class MyApplication : Application
    public static MyApplication Instance { get; private set; }

    protected MyApplication(IntPtr javaReference, JniHandleOwnership transfer) : base(javaReference, transfer)
      Instance = this;

3. Check the MyApplication.Instance in OnCreate of the MainActivity. -> It's null

# Expected behavior

The MyApplication should be instantiated. 

# Actual behavior
With the new Release the constructor will never be called.

# Supplemental info (logs, images, videos)

# Test environment (full version information)

We have the same exact issue, OnCreate is never called in my Application subclass.

Seems to work on the Alpha channel but not Beta or Stable right now.
