由于大图导致应用程序崩溃

【问题标题】：App crash because of big picture由于大图导致应用程序崩溃
【发布时间】：2013-11-13 10:35:39
【问题描述】：

在我的活动中，我有以下代码：

int picture = Const.a1;
Const.backgroundBitmap = BitmapFactory.decodeResource(getResources(), picture);
Const.backgroundBitmapBonus0 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[0]);
Const.backgroundBitmapBonus1 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[1]);
Const.backgroundBitmapBonus2 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[2]);
Const.backgroundBitmapBonus3 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[3]);

Const.bitmapBackBonus = new Bitmap[4];

Const.bitmapBackBonus[0]= Const.backgroundBitmapBonus0;
Const.bitmapBackBonus[1] = Const.backgroundBitmapBonus1;
Const.bitmapBackBonus[2] = Const.backgroundBitmapBonus2;
Const.bitmapBackBonus[3] = Const.backgroundBitmapBonus3;

在Const 课堂上我有

public static int[] bonus_back = {  R.drawable.back_b0 ,    R.drawable.back_b1 ,    R.drawable.back_b2 ,    R.drawable.back_b3};

当我在我的设备上运行应用程序时它崩溃了，而在 AVD 中它运行良好。

如何正确使用这些图片？

编辑：

使用http://developer.android.com/training/displaying-bitmaps/load-bitmap.html 的新代码 还是一样的问题

    Const.screenWidth = this.getWindowManager().getDefaultDisplay().getWidth();
    Const.screenHeight = this.getWindowManager().getDefaultDisplay().getHeight();

    int picture = Const.a1; 
    Const.backgroundBitmapBonus0 = decodeSampledBitmapFromResource(getResources(), Const.bonus_back[0], Const.screenWidth, Const.screenHeight);
    Const.backgroundBitmapBonus1 =decodeSampledBitmapFromResource(getResources(), Const.bonus_back[1], Const.screenWidth, Const.screenHeight);
    Const.backgroundBitmapBonus2 = decodeSampledBitmapFromResource(getResources(), Const.bonus_back[2], Const.screenWidth, Const.screenHeight);
    Const.backgroundBitmapBonus3 = decodeSampledBitmapFromResource(getResources(), Const.bonus_back[3], Const.screenWidth, Const.screenHeight);

    Const.backgroundBitmap = decodeSampledBitmapFromResource(getResources(), picture, 100, 100);


    /*Const.backgroundBitmap = BitmapFactory.decodeResource(getResources(), picture);
    Const.backgroundBitmapBonus0 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[0]);
    Const.backgroundBitmapBonus1 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[1]);
    Const.backgroundBitmapBonus2 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[2]);
    Const.backgroundBitmapBonus3 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[3]);
     */
    Const.bitmapBackBonus = new Bitmap[4];

    Const.bitmapBackBonus[0]= Const.backgroundBitmapBonus0;
    Const.bitmapBackBonus[1] = Const.backgroundBitmapBonus1;
    Const.bitmapBackBonus[2] = Const.backgroundBitmapBonus2;
    Const.bitmapBackBonus[3] = Const.backgroundBitmapBonus3;

【问题讨论】：

  • 一定有一些logcat。如果您发布这些内容，则很容易找到原因。
  • 在 avd 中它可以工作，但是当我在我的设备中播放它时它没有，而且我没有成功在调试状态下运行它，所以我首先将它复制到我的设备然后运行它
  • 为什么不能在你的设备上运行它？
  • 它没有出现在选项中（我在设备中启用了调试，并使用USB将设备连接到计算机）
  • 你还没有安装你的 USB 驱动程序 - 看看这里stackoverflow.com/questions/7510471/…。

【解决方案1】：

如果图像太大，您可能内存不足。

查看http://developer.android.com/training/displaying-bitmaps/load-bitmap.html 了解如何加载图片的缩小版本。

【讨论】：

  • 我现在更改了上面示例中的代码，但仍然是相同的问题。我将使用新代码编辑我的问题
  • 然后您需要发布您的 LogCat 以查看导致错误的确切原因。在 Eclipse 中激活 LogCat 视图去 Window->Show View->LogCat.
  • 如果我正确理解您的代码，您将加载 4 个宽度和高度与屏幕相等的位图。您可能不会同时显示它们，因此您应该根据需要管理它们的加载。您的设备上只有这么多内存，所以加载这么多大位图会导致内存不足。
  • 实际上，您可以看到加载位图时内存不足的情况。在异常发生之前检查你的 logcat 中随后的 15872016 字节分配，你会看到内存是如何增加的，直到设备用完为止。
  • 我想让背景每秒改变 4 帧。那么最好的方法是什么？
