[18o]

Hi, i'm working with tauri 2 for building android app.
but didn't find a way to set the Activity fullscreen and how to hide the status bar ?
does anyone can help me? even just some idea is very thanks.

Were you able to find an answer to this?

Changing the MainActivity.ks file to this:

package // Keep the old value here

import android.os.Bundle
import androidx.core.view.WindowCompat

class MainActivity : TauriActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    WindowCompat.setDecorFitsSystemWindows(window, false)
  }
}

and adding this to the theme file (i forgot its path)

<item name="android:statusBarColor" tools:targetApi="l">@android:color/transparent</item>

should mostly work.

A problem with this is opening the keyboard doesn't shift the layout so if you have input fields at the bottom half of the screen they won't be visibile anymore. I did not look into how to best solve this yet.

still working on the latest rc version?

[FabianLars]

i think it's still working, yes. i did not hear any reports saying otherwise.

for me it doesn't work. I found some solution, but when I change phone orientation then I see black bar on the side ... in MainActivity.kt: Rather:

`` package com.tauri.dev

import android.os.Bundle
import androidx.core.view.WindowCompat
import androidx.core.view.WindowInsetsCompat
import androidx.core.view.WindowInsetsControllerCompat

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

    // Allow content to extend under the system bars
    WindowCompat.setDecorFitsSystemWindows(window, false)

    // Get the insets controller to manage system UI
    val windowInsetsController = WindowCompat.getInsetsController(window, window.decorView)


    // Ensure the status bar is fully transparent
    window.statusBarColor = android.graphics.Color.TRANSPARENT
}

}

}

}

Thank you very much for the code, I think I've tried out the final solution, this works on my device, I added the ability to hide all status bars, navigation bars, screen notches, and tested that it works in my device

package // Keep your package name
import android.os.Bundle
import androidx.core.view.WindowCompat
import androidx.core.view.WindowInsetsCompat
import androidx.core.view.WindowInsetsControllerCompat

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

        // Allow content to extend under the system bars
        WindowCompat.setDecorFitsSystemWindows(window, false)

        // Get the insets controller to manage system UI
        val windowInsetsController = WindowCompat.getInsetsController(window, window.decorView)

        // Hide both status bar and navigation bar
        windowInsetsController.apply {
            hide(WindowInsetsCompat.Type.systemBars())
            systemBarsBehavior = WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
        }

        // Make both bars transparent
        window.statusBarColor = android.graphics.Color.TRANSPARENT
        window.navigationBarColor = android.graphics.Color.TRANSPARENT

        // Handle display cutout (notch)
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.P) {
            window.attributes.layoutInDisplayCutoutMode = 
                android.view.WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES
        }
    }
}

Thanks, I found it already too, just forgot to post it here. Good job.

[thiagovianav]

is there a way to use it like a function? my app doesn't need all the time, just in reader mode

[saurL]

for anyone wondering if you add

ViewCompat.setOnApplyWindowInsetsListener(findViewById(android.R.id.content)) { view: View, insets: WindowInsetsCompat ->
            val bottomInset = insets.getInsets(WindowInsetsCompat.Type.ime()).bottom
            view.setPadding(0, 0, 0, bottomInset)
            insets
        }

in override fun onCreate(savedInstanceState: Bundle?) { it fix the keyboard issue.

i dont know if anyone is still looking for this answer the Clean way to do it is to add the enableEdgeToEdge import and implement full-screen mode:

Current State

Your MainActivity.kt is very simple:

package com.XXXX.app

class MainActivity : TauriActivity()

Proposed Changes

To enable edge-to-edge (full screen) display, you need to:

1. Add the import statement at the top:

   import androidx.activity.enableEdgeToEdge

2. Override the onCreate method and call enableEdgeToEdge() before calling super.onCreate():

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

3. Add the necessary Android import for Bundle:

   import android.os.Bundle

Final Result

The complete file should look like this:

package com.XXXX.app

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

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

4. Add implementation("androidx.activity:activity-ktx:1.10.1") to the dependencies in build.gradle.kts

Important Notes

• enableEdgeToEdge() must be called before super.onCreate() for it to work properly
• This will make your app draw content under the system bars (status bar and navigation bar)
• You may need to handle window insets in your UI to prevent content from being obscured by system bars
• This requires androidx.activity:activity version 1.6.0 or higher in your dependencies
