Sure, here is the code to check storage permission in Android:

public boolean checkStoragePermission() { // Check if the permission has already been granted int permissionStatus = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

Code snippet

// If the permission has not been granted, request it
if (permissionStatus != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 100);
    return false;
} else {
    // The permission has already been granted
    return true;
}

}

This code will first check if the WRITE_EXTERNAL_STORAGE permission has already been granted. If it has not been granted, the code will request the permission from the user. If the user grants the permission, the code will return true. Otherwise, the code will return false.

To use this code, you would need to call the checkStoragePermission() method in your app. For example, you could call the method in your app's onCreate() method.

Here is an example of how you could call the checkStoragePermission() method in your app's onCreate() method:

public void onCreate() { super.onCreate();

Code snippet

// Check if the storage permission has been granted
if (checkStoragePermission()) {
    // The permission has already been granted
} else {
    // Request the permission
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 100);
}

Code for storage permission

    public void checkForStoragePermission(){

        if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE)    != PackageManager.PERMISSION_GRANTED) { 

            // Permission is not granted

            // Should we show an explanation

            if (ActivityCompat.shouldShowRequestPermissionRationale(this,     Manifest.permission.READ_EXTERNAL_STORAGE)) { 

                // Show an explanation to the user *asynchronously* -- don't block

                // this thread waiting for the user's response! After the user

                // sees the explanation, try again to request the permission.

                ActivityCompat.requestPermissions(this,        new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
