The Navigation component has a Gradle plugin called Safe Args that generates simple object and builder classes for type-safe navigation and access to any associated arguments. Safe Args is strongly recommended for navigating and passing data, because it ensures type-safety.

Hi, Stevdza. Great video, right to the point. Is there a video example showing how to pass more than 1 value with safe args? I would really appreciate this, because i'm struggling with this issue on my project. Thank you so much!!

@StevdzaSan 4 жыл бұрын

You can pass multiple values using Array as a type, or your own data class as parcelable. I'll make a video about it in the future.

This worked 4 years ago, but it doesn't in 2024. I'm an experienced programmer, but totally new to Android. Can anyone point me in the right direction? the structure of the gradle.build files has completely changed in the meantime and something as simple as setting "classpath" gives an error.

Thanks a lot. I am having problems when trying to define val args : SecondFragmentArgs by navArgs(). The error says: "property delegate must have a getvalue". However I noticed that android didn´t generate the three classes (two for directions and one for arguments). Do you have any suggestion for me, please?

So... should I be using fragments instead of activities now? How do they act with the application's main thread?

Navigation component is well structured and easy to use. Using fragments with just one activity is one of the main purposes of nav component. Btw more videos coming about nav component.

I tried to the following in MainActivity where Navcontroller is setted. bundle.putString(...); NavController.setGraph(R.navigation.mobile_navigation,bundle); On receiving Fragments String role = getArguments.getString("role"); Only recieving the role onStartDestinationFragment which is Home but in others fragments(gallery,profile etc...) i m receiving null value. I tried safeArgs ,Bundles I still receiving null value of role when in other Fragments. 🙏Hope I m clear

Dont understand the (by navargs) syntax , would you explain please

@StevdzaSan 3 жыл бұрын

That's a property delegate. We are lazily getting arguments during variable declaration. Something similar to "by lazy {}". Classes with postfix "Args" and "Direction" are automatically generated by Safe Args plugin.

how do I fix safeargs for java? My build.gradle file doesn't have a buildscript section, and my dependencies don't contain any classpaths I added the following to build.gradle(project): id("androidx.navigation.safeargs") version "2.5.3" apply false and id ("androidx.navigation.safeargs") in build.gradle(module). When I write the text of myArg is red. Something's wrong but I don't know what. Also in my java file (FirstFragment), how do I navigate to SecondFragment and send my data? Currently I navigate this way: NavHostFragment.findNavController(FirstFragment.this) .navigate(R.id.action_FirstFragment_to_SecondFragment); But I have a variable int count, and I want to send the value of it as myArg. How do I do that?
