Android: MissingMethodException: Method not found: ‘Default constructor not found…
An article by 
Suddenly started getting these error messages on device (build worked fine otherwise, but tcp socket stopped working)
You can view device log with command line> adb logcat -s Unity ActivityManager PackageManager dalvikvm DEBUG
Solutions:
– Use IL2CPP build instead of Mono2x
– Or, set Stripping Level: Disabled (any other stripping level didn’t work)
Probably the cause was changing Api Compatibility Level from “.net 2.0 Subset” into “.net 2.0”..
