Crash de l'application Android

Question

J'ai créé une application Android qui fonctionne parfaitement sur mon appareil. J'ai envoyé l'APK à quelqu'un, et cela a fonctionné sur son appareil aussi. À un moment donné, il voulait modifier quelque chose dans l'application. Donc je l'ai envoyé sur le code source complet.

Maintenant, il me dit que le code source ne fonctionne pas pour lui. Il compile bien, mais quand il l'exécute depuis Eclipse, il se bloque.

Je suis sûr à 100% que je lui ai envoyé le bon code, ça marche très bien pour moi. Apparemment, il n'y a pas de raison pour le crash. Je lui ai demandé de m'envoyer les erreurs logcat et je n'ai pas l'air de trouver le problème.

Ici, il est (en partie):

Answer 1

Le problème que vous rencontrez est une jolie habitude un: votre application est en cours d'exécution de mémoire quand il essaie d'allouer l'espace pour une Bitmap que vous êtes en utilisant.

Il existe des techniques que vous pouvez rechercher sur le site de documentation Google pour les programmeurs Android. Par exemple Managing Bitmap Memory.

Pour éviter l'erreur, c'est une fonction assez bon (encore une fois, de Google docs):

public static int calculateInSampleSize(
      BitmapFactory.Options options, int reqWidth, int reqHeight) { 
    // Raw height and width of image 
    final int height = options.outHeight; 
    final int width = options.outWidth; 
    int inSampleSize = 1; 

    if (height > reqHeight || width > reqWidth) { 

     // Calculate ratios of height and width to requested height and width 
     final int heightRatio = Math.round((float) height/(float) reqHeight); 
     final int widthRatio = Math.round((float) width/(float) reqWidth); 

     // Choose the smallest ratio as inSampleSize value, this will guarantee 
     // a final image with both dimensions larger than or equal to the 
     // requested height and width. 
     inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio; 
    } 

    return inSampleSize; 
} 

public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId, 
     int reqWidth, int reqHeight) { 

    // First decode with inJustDecodeBounds=true to check dimensions 
    final BitmapFactory.Options options = new BitmapFactory.Options(); 
    options.inJustDecodeBounds = true; 
    BitmapFactory.decodeResource(res, resId, options); 

    // Calculate inSampleSize 
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight); 

    // Decode bitmap with inSampleSize set 
    options.inJustDecodeBounds = false; 
    return BitmapFactory.decodeResource(res, resId, options); 
} 

Ce qui est fait est:

1. Vérifiez la hauteur et la largeur de votre Bitmap sans en fait le charger dans la mémoire
2. Ajuster la taille d'échantillonnage pour qu'elle tienne dans la mémoire, mais conserve les dimensions requises

Answer 2

Essayez d'augmenter VM Heapmémoire dans AVD comme .

Dans le menu, sélectionnez Fenêtre =>périphérique virtuel Android Gestionnaire => sélectionnez AVD que vous utilisez => cliquez sur le bouton modifier .

Dans l'ancienne version d'ADT.

Dans la nouvelle version d'ADT.

Lorsque vous créez AVD, il prend 24 VM Heap par défaut. mais votre application a besoin de plus de mémoire donc, vous le définissez comme 64.
