[feat] EdgeToEdge on Android / iOS

[InfinityDevTech]

Describe the problem

On Android, there is a feature to allow the app to hide the Notification bar and the Navigation bar, otherwise called Edge to Edge.
Documented Here

I know iOS has a similar API, but I am on android myself so this will be targeted mostly towards that.

Describe the solution you'd like

It would be nice if we can programmatically change this, like the documentation says in the android dev site, or get a tauri.conf.json line about this as well.

Alternatives considered

A plugin could be written, but this seems more "first-party" to me.

Additional context

This could be implemented by allowing plugins to hook into the onCreate event of the TauriActivity.

@FabianLars Is there currently any way to override default method implementations in the root view controller or activity on iOS/Android? E.g. onCreate as mentioned by @InfinityDevTech?

[FabianLars]

yes there is. it's not the nicest way because we have no "patch implementation" (iirc that's what the team wanted to have).

Anyway, first make sure to remove the src-tauri/gen/android/ folder from any gitignores (this requires you to have added it yourself - the default templates want you to commit the folder).
Then add implementation("androidx.activity:activity-ktx:1.9.3") to the dependencies section in gen/android/app/build.gradle.kts.
Lastly, modify gen/android/app/src/main/java/com/<appname>/app/MainActivity.kt like this

package com.testproject.app

import android.os.Bundle
import androidx.activity.enableEdgeToEdge

class MainActivity : TauriActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
        enableEdgeToEdge()
        super.onCreate(savedInstanceState)
    }
}

Edit: Yes, i tested this (i had to because i had to do it trial and error style 😂 )

This could be implemented by allowing plugins to hook into the onCreate event of the TauriActivity.

Would this be possible? I would expect the plugins to be registered too late for this, no? (honestly no idea / can't remember)

Theoretically, couldn't the android thread wait until all plugins are loaded THEN call their onCreate's?

Allowing plugins to use the onCreate seems kinda nifty for quite a few things.
