Comment réparer l'application Android ressources

Question

Je fuite ai code suivant dans mon Activity: -

public void showPopup(View view) { 
    View popupView = getLayoutInflater().inflate(R.layout.popup_layout, null); 
    PopupWindow popupWindow = new PopupWindow(popupView, 
      WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT); 
    // Example: If you have a TextView inside `popup_layout.xml` 
    ImageView imageView = (ImageView) popupView.findViewById(R.id.popupImageView); 
    if (mImagePath != null) { 
     if (Utility.fileExist(mImagePath)) { 
      imageView.setImageBitmap(BitmapFactory.decodeFile(mImagePath)); 
     } else { 
      Toast.makeText(this, "Image not found!", Toast.LENGTH_LONG).show(); 
     } 
    } else { 
     Toast.makeText(this, "Image not found!", Toast.LENGTH_LONG).show(); 
    } 

    popupWindow.setFocusable(true); 

    popupWindow.setBackgroundDrawable(new ColorDrawable()); 
    int location[] = new int[2]; 

    view.getLocationOnScreen(location); 

    popupWindow.showAtLocation(view, Gravity.NO_GRAVITY, 
      location[0], location[1] + view.getHeight()); 
} 

Lorsque l'écran tourne, je me l'erreur suivante. Pourriez-vous expliquer comment corriger cette erreur: -

Answer 1

Vous pouvez fermer votre pop-up dans Activity.onDestroy() méthode:

if (popupWindow.isShowing()) { 
    popupWindow.dismiss(); 
} 

Answer 2

Une façon serait d'utiliser LeakCanary pour détecter automatiquement les fuites. Aussi, assurez-vous d'appeler dismiss() sur votre PopupWindow lorsque l'activité est en pause ou détruite.
