Is it possible to declare an object of a native class (in c++) in java (android sdk)?

The only solution would be to create a JNI lib that would serve as a communication layer between your Java and C++ code.
That Lib would need to :
1- Contain methods that receive your needed Java Objects as JObject. (lookup this post for how to use the jobject : how to pass java class instance as a parameter to JNI method?
2- Request your C++ objects to your native code
3- Do whatever you need to do with both objects.
Hope it helps ;)
Cheers !

Native classes which be declared and defined in c++.
However when you use JNI, you define a Java class with native method and generate C code from this to implement using javah

No. The only objects that Java recognizes are Java objects.
The JNI approach allows you to create a native method for a Java class, and a JNI method implemented in C / C++ can create other C / C++ objects. However, there is no way that you can pass such an object back to Java so that the Java code can use it directly.
