Suddenly started getting these error messages on device (build worked fine otherwise, but tcp socket stopped working)
\nYou can view device log with command line> adb logcat -s Unity ActivityManager PackageManager dalvikvm DEBUG<\/p>\n

Solutions:<\/strong>
\n– Use IL2CPP build instead of Mono2x
\n– Or, set Stripping Level: Disabled (any other stripping level didn’t work)<\/p>\n

Probably the cause was changing Api Compatibility Level from “.net 2.0 Subset” into “.net 2.0”..<\/p>\n
