PSS memory Leak on Android when app is left to idle (19 MB/Hr to 190 MB/Hr)



Steps to reproduce:

# Open the attached user's Project “LeakMemory”
# Select Android build target
# Add the default scene in the build settings window
# Check "Development Build"
# Check "Autoconnect Profiler"
# Build the application
# Run the application and let it idle
# Using the "Memory Profiler" tool take screenshots every 5 minutes
# Observe and compare the memory consumption

Expected results: Memory consumption doesn’t exponentially increase within minutes
Actual results: Memory consumption increased by 40 to 80 megabytes in 15 minutes after letting the application idle
