How to setContent in activity after first time require permission

I have tried to require permission in activity and then get the function of compose, but when i first time get the permission, it can not directly get the content of compose.

class MainActivity : AppCompatActivity() {

    val viewModel by viewModels<MainViewModel>()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        if (allPermissionsGranted()) {
            // the setContent code not executed after getting the permission first time
            setContent {
                MyTheme {
                    Main(
                        viewModel = viewModel,
                        backDispatcher = onBackPressedDispatcher
                    )
                }
            }
        } else {
            ActivityCompat.requestPermissions(
                this, REQUIRED_PERMISSIONS, REQUEST_CODE_PERMISSIONS)
        }
    }

    private fun allPermissionsGranted() = REQUIRED_PERMISSIONS.all {
        ContextCompat.checkSelfPermission(
            baseContext, it) == PackageManager.PERMISSION_GRANTED
    }

    companion object {
        private const val REQUEST_CODE_PERMISSIONS = 10
        private val REQUIRED_PERMISSIONS = arrayOf(Manifest.permission.CAMERA)
    }
}

Activities do not get recreated after a permission grant. So, in your case, nothing will happen in the app after the permission grant. This is unrelated to Compose; you would get the same behavior with setContentView() where you have setContent {}.

Move your setContent {} logic into a different function. Call it from onCreate() where you have it now. And, override onRequestPermissionsResult(), and call that function from there if you were granted permission.

A more Compose-y way would be to remember whether you have permission and update that state from onRequestPermissionsResult() if you were granted permission. Do all that from inside setContent(), and Compose will recompose on the state change.

Hi you can achieve it by using fragments. You should check permission, request and handle response

If permission granted -> navigate to the fragment

If permission not granted wait until user grants and upon response -> navigate to the fragment
