我创建了一个可以在我的设备上完美运行的 Android 应用程序。我已将 APK 发送给某人，它也可以在他的设备上运行。

有一次，他想修改应用程序中的某些内容。所以我把完整的源代码发给了他。

现在他告诉我源代码对他不起作用。它编译得很好，但是当它从 Eclipse 中运行它时它会崩溃。

我 100% 确定我已经向他发送了正确的代码，这对我来说很好用。显然没有理由崩溃。

我让他给我发送 logcat 错误，我似乎没有发现问题。

这是（部分）：

尝试将AVD中的VM 堆 内存增加到64。

在菜单中选择 Window => Android Virtual Device Manager => 选择您使用的avd => 点击编辑按钮。

在旧版本的 ADT 中。

在此处输入图像描述

在新版本的 ADT 中。

在此处输入图像描述

当您创建新的 AVD 时，默认使用 24 个 VM 堆。但是您的应用程序需要更多内存，因此您将其设置为 64。

您遇到的问题很常见：​​您的应用程序在尝试为您正在使用的位图分配空间时内存不足。

您可以在面向 Android 程序员的 Google 文档站点中查找一些技术。例如管理位图内存。

为避免该错误，这是一个非常好的功能（同样来自 Google 文档）：

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);
}

什么是：

  1. 验证位图的高度和宽度，而无需将其实际加载到内存中
  2. 调整采样大小，使其适合内存，但保持所需的尺寸
