How to take run time permission in android 13 Programmatically in android studio 2023

Hello freind today will be learn about how to run permission in android 13 in android studio.

Before starting this project, I have already told manage_external_storage and call phone permission. Click here to see it.Manage_External_Storage and Call phone.
Let's start creating the project First of all we will create a project in Android Studio.After creating the project, we will use this code in Splash or MainActivity.I will use run time permissions here in SplashActivity.
activity_splash.xml

            public void run() {
                Intent intent=new Intent(SplashActivity.this,MainActivity.class);
                startActivity(intent);
                finish();
            }
        },2000);
    }
}

Before Android 13, we had to take permission to use Write external storage and Read external storage, but after the arrival of Android 13, we did not get storage permission for their use.

Type of Media	Permission
Images and Photos	READ_MEDIA_IMAGES
Videos	READ_MEDIA_VIDEO
Audio files	READ_MEDIA_AUDIO

Here we will use the type of permission required in the project. We have used Read media image to get video and image from storage. Click here for more information.
In the above code we have used a variable RUNTIMEPERMISSION of a string type and after using it we have used different permissions depending on whether it is bigger or smaller than android 13.

Here we are use a condition if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.TIRAMISU) { RUNTIMEPERMISSION= Manifest.permission.READ_MEDIA_IMAGES } else { RUNTIMEPERMISSION=Manifest.permission.WRITE_EXTERNAL_STORAGE }

By using this we can switch the permission when android 13 asks for RUNTIMEPERMISSION=Manifest.permission.WRITE_EXTERNAL_STORAGE.And if Android is greater than or equal to 13 then the permission variable will contain runtimePermissions = manifest.permissions.READ_MEDIA_IMAGES.
If the app gets the permission then it will run in the mainActivity and if the permission is denied then the app will finish because we have used the finish method. If you want to finish then you will have to ask for permission again and call this method ActivityCompat.requestPermissions(this,new String[]RUNTIMEPERMISSION},PERMISSION_CODE) again. can do
