Impossible d'éditer les images de moins de 50x50 pixels

Question

Lorsque j'essaie de définir des fonds d'écran sur le bureau, je reçois ce message. Pourquoi? Et comment supprimer ce message?

Mon code: -Lorsque bouton clic:

Intent intent = new Intent();              
intent.setAction(Intent.ACTION_ATTACH_DATA);          
intent.addCategory(Intent.CATEGORY_DEFAULT);          
intent.setDataAndType(ContactsContract.Contacts.CONTENT_URI, "image/*");   
intent.putExtra("mimeType", "image/*");           
startActivityForResult(Intent.createChooser(intent, "Select service:"), position); 

puis onActivityResult:

@Override                  
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data);      

    resultView.setDrawingCacheEnabled(true);         
    Bitmap bitmap = resultView.getDrawingCache();        
    new TaskSetWallpaper(GalleryActivity.this).execute(bitmap);     
}                    

et classe interne pour le papier peint de jeu:

public class TaskSetWallpaper extends AsyncTask<Bitmap, Void, Bitmap>        
{                         
    private Context context;                  
    private ProgressDialog pDialog;                 

    TaskSetWallpaper(Context context)                
    {                        
     this.context = context;                  
    }                        

    @Override                      
    protected void onPreExecute()                 
    {                        
     super.onPreExecute();                  
     pDialog = new ProgressDialog(context);              
     CharSequence text = getText(R.string.crop__wait);           
     pDialog.setMessage(text);                 
     pDialog.setIndeterminate(false);               
     pDialog.setCancelable(false);                
     pDialog.show();                    
    }                        

    @Override                      
    protected Bitmap doInBackground(Bitmap... bitmaps)            
    {                        
     WallpaperManager wallpaperManager = WallpaperManager.getInstance(getApplicationContext()); 
     try                       
     {                       
      wallpaperManager.setBitmap(bitmaps[0]);             
     } catch (IOException e)                  
     {                       
      e.getMessage();                   
     }                       
     return null;                    
    }                        

    @Override                      
    protected void onPostExecute(Bitmap bitmap)              
    {                        
     super.onPostExecute(bitmap);                
     pDialog.dismiss();                   
     CharSequence text = getText(R.string.set_wlp_toast);          
     Toast toast = Toast.makeText(context, text, Toast.LENGTH_SHORT);       
     toast.setGravity(Gravity.CENTER, 0, 0);              
     toast.show();                    
    }                        
}
