Why cannot you run standard Java bytecode on Android?

Android uses Dalvik Virtual Machine (DVM) which requires a special bytecode. First of all, we have to convert Java class files into Dalvik Executable files using an Android tool called “dx”.

What is the difference between Page-Validate and Property-Validate methods?

Validate method is used to validate all the properties present on a page. If a page has embedded pages, this method works recursively to validate all the properties. This method consumes lot of system resources and takes more time. If you want to validate specific properties use Obj-Validate method with Rule-Obj-Validate rule.

Property-Validate method is used to impose restrictions on a property value. Use Edit validate rule along with Property-Validate method to impose restrictions. You can validate multiple properties using Property-Validate method.
