    h5.Steps to reproduce: 1. Create a defaut alloy or clasic app. Make sure you have services enabled. 2. Using the components & SDK in the description build for android device/emulator. 3. Let the app launch. h5.Actual Results: 1. The app crashes 2-3 seconds after launch with error: {code} [WARN] : TiVerify: (Timer-0) [5003,5003] Verifying module licenses... [ERROR] : TiApplication: (Timer-0) [4,5007] Sending event: exception on thread: Timer-0 msg:java.lang.NoClassDefFoundError: Failed resolution of: Lti/modules/titanium/network/NonValidatingSSLSocketFactory;; Titanium 4.0.1,2016/03/08 10:35,72e9f11 [ERROR] : TiApplication: java.lang.NoClassDefFoundError: Failed resolution of: Lti/modules/titanium/network/NonValidatingSSLSocketFactory; [ERROR] : TiApplication: at Source) [ERROR] : TiApplication: at java.util.Timer$ [ERROR] : TiApplication: Caused by: java.lang.ClassNotFoundException: Didn't find class "" on path: DexPathList[[zip file "/data/app/"],nativeLibraryDirectories=[/data/app/, /vendor/lib, /system/lib]] [ERROR] : TiApplication: at dalvik.system.BaseDexClassLoader.findClass( [ERROR] : TiApplication: at java.lang.ClassLoader.loadClass( [ERROR] : TiApplication: at java.lang.ClassLoader.loadClass( [ERROR] : TiApplication: ... 2 more [ERROR] : TiApplication: Suppressed: java.lang.ClassNotFoundException: [ERROR] : TiApplication: at java.lang.Class.classForName(Native Method) [ERROR] : TiApplication: at java.lang.BootClassLoader.findClass( [ERROR] : TiApplication: at java.lang.BootClassLoader.loadClass( [ERROR] : TiApplication: at java.lang.ClassLoader.loadClass( [ERROR] : TiApplication: ... 3 more [ERROR] : TiApplication: Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack available {code} 2. This might be due to the fact that the "NonValidatingSSLSocketFactory" class is removed as a part of the google security fix. 3. When built with SDK 3.5.1.GA & 4.0.0.GA this issue is not seen. h5.Expected Results: 1. The app should not crash.
