Your Developer Credentials 5. Privacy and Information 6. All the above code is already present in your project. We have seen the basic "Hello, World! Now, let's build one calculator app that will take input from the user and will perform the following four actions we will only cover the logical part :. So, as in the "Hello, World!
In the "Calculator App" also, we are going to define four different methods for performing the above four operations. Here, you can see that we have four functions named add for the addition of two numbers , sub for the subtraction of two numbers , multiply for the multiplication fo two numbers , and divide for the division of two numbers.
The return type of each function is jint. Also, each function is taking two integers as parameters and both are of type jint. Now, our next task is to load the native-lib file in our Kotlin file.
So, we can do that by using the System. Now, declare four Kotlin external methods with the same name as used in the native-lib file. That's it, you are done with all the four functions. What happens is that the NDK makes the. For example, if we are having mips, x86, armeabi, armeabi-v7a, armeabi-v8a, then the.
So, if the size of one. Usually, when we are dealing with some cross-platform application or we need to build some high-performance application, then we use native languages in our application.
Otherwise, it is advised to go with Java or Kotlin. Check our all the Android tutorial here. Do share this blog with your fellow developers to spread the knowledge.
