Make RedLaser work with Mono for Android

We have a very simple testing project to integrate red laser SDK into Mono for Android. It works if we do not include license file and we can use red laser to scan in our Mono for Android app up to 50 scans (maximum limit for trial) But after we bought the license and input license file, then we will have library not found error. The error message is below. We need some one to trouble shoot on this issue and make our testing project works with red laser SDK for Mono Android with our license file. 04-01 14:53:31.021 W/dalvikvm( 8472): threadid=1: thread exiting with uncaught exception (group=0x40c4ea68) 04-01 14:53:31.021 E/AndroidRuntime( 8472): FATAL EXCEPTION: main 04-01 14:53:31.021 E/AndroidRuntime( 8472): [login to view URL] 04-01 14:53:31.021 E/AndroidRuntime( 8472): at android.app.ActivityThread.acce04-01 14:53:31.021 E/AndroidRuntime( 8472): at RLSDK.c.(RLSDK_:80) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL](RLSDK_:260) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472)04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]$600([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]$[login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL](Native Method) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]$[login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL](Native Method) 04-01 14:53:31.021 E/AndroidRuntime( 8472): Caused by: [login to view URL]: Couldn't load redlaser: findLibrary returned null 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at [login to view URL]([login to view URL]) 04-01 14:53:31.021 E/AndroidRuntime( 8472): at com.ebay.redlasersdk.recognizers.NewLaserScanner.(RLSDK_:127) 04-01 14:53:31.021 E/AndroidRuntime( 8472): ... 17 more
