位图加载outofmemory android

-1

我正在使用矩阵移动和旋转的不同位图制作壁纸。现在，我有8个大小为300 X 300的位图，每个都是png。我需要他们一直在屏幕上。我在OnCreate使用此：位图加载outofmemory android

sun = BitmapFactory.decodeResource(getResources(), R.drawable.sun); 
      planet_1 = BitmapFactory.decodeResource(getResources(), 
        R.drawable.planet_1); 
      scene_1 = BitmapFactory.decodeResource(getResources(), 
        R.drawable.full_scaled); 
      planet_2 = BitmapFactory.decodeResource(getResources(), 
        R.drawable.planet_2); 
      scene_2 = BitmapFactory.decodeResource(getResources(), 
        R.drawable.scene_2); 
      planet_3 = BitmapFactory.decodeResource(getResources(), 
        R.drawable.planet_3); 
      scene_3 = BitmapFactory.decodeResource(getResources(), 
        R.drawable.scene_3); 
      bg = BitmapFactory.decodeResource(getResources(), R.drawable.bg);

他们加载预览很好，但是当我尝试设置壁纸它崩溃了：

您是否试过检查此链接http://developer.android.com/training/displaying-bitmaps/index.html –

在Android Manifest中添加大堆属性 –

参考this Documention你会得到明确Dispalying位effcienly

你可以尝试的东西像这样

BitmapFactory.Options opts = new BitmapFactory.Options(); 
opts.inPreferredConfig = Bitmap.Config.RGB_565; // or Bitmap.Config.ARGB_4444 
sun = BitmapFactory.decodeResource(getResources(), R.drawable.sun, opts);

这是最简单的方法和值得尝试。当然，这会使你的图形质量更差，但取决于它们的外观，你甚至可能看不出它们的差异。
