Android 7.1 Write To Text File

Guys New to Nougat come from Jelly bean Trying to write to sdcard a text file I know I now have to request permissions but cant find any code that works Tried the following

Solution 1:

Either you have the permission and can do the try catch block where you write into the file or you have to do it in the onRequestPermissionsResult.

Something like :

publicvoidyourMethod(){
    booleanhasPermission= (ContextCompat.checkSelfPermission(data_entry.this,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
    if(hasPermission){
      // write
    }else{
      // ask the permission
      ActivityCompat.requestPermissions(data_entry.this,
                        newString[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                        REQUEST_WRITE_STORAGE);
      // You have to put nothing here (you can't write here since you don't// have the permission yet and requestPermissions is called asynchronously)
   }
}

@OverridepublicvoidonRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNullint[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    // The result of the popup opened with the requestPermissions() method// is in that method, you need to check that your application comes hereif (requestCode == REQUEST_WRITE_STORAGE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // write
        }
    }
}

This is what you need: https://developer.android.com/training/articles/scoped-directory-access.html#accessing

You have to ask the user to give the rights to access it.
