我最近重建我的Andr​​oid项目的目标从2.1 2.2。

I recently rebuilt my Android project to target 2.2 from 2.1.

在旧的项目，我没有指定目标SDK（清单并没有包含这样的内容：安卓的minSdkVersion =8）。运行时，这给了我在控制台中的错误，但一切正常，所以我没有用它愚弄。

In the old project, I did not specify a target SDK (the manifest did not contain something like: android:minSdkVersion="8"). This gave me an error in the console when running, but everything worked fine so I didn't fool with it.

新项目现在采用Android：=的minSdkVersion8在清单

The new project now uses android:minSdkVersion="8" in the manifest.

但现在从/绘制-nodpi /文件夹可绘制我在加载具有缩放，使它们小得多，显著改变所需的视觉效果。

But now my drawables from the /drawable-nodpi/ folder are loading with scaling, making them much smaller and significantly changing the desired visuals.

如果我剪下从我的清单中的标签，他们正确加载无需缩放。

If I cut out the tag from my manifest, they load properly without scaling.

加载，即使我的图片，像这样的时候：

Even when loading my images like so:

        BitmapFactory.Options opts = new BitmapFactory.Options();
        opts.inScaled = false;   
        Bitmap bm = BitmapFactory.decodeResource(_resources, resId, opts);

当我宣布在清单中最小的SDK他们仍在进行缩放，但是不会缩放如果删除该标签。

They are still scaled when I declare the minimum SDK in the manifest, but not scaled if I remove that tag.

这是怎么回事？我怎么能不结垢，同时还宣布最低SDK加载它们？

Why is this happening? How can I load them without scaling while still declaring the minimum SDK?

推荐答案

有是赋予另一种解释的这里：

There is another explanation given here:

如果你不指定＆LT;支持的屏幕>或minSdk，那么你的应用程序将在兼容模式下运行，这意味着它给了HVGA（240×320）虚拟屏幕，然后按比例作为一个整体。所以，你的图像将被缩小。

"If you don't specify <supports-screens> or minSdk, then your app will run in compatibility mode, meaning that it's given an HVGA (240x320) "virtual screen", which is then scaled as a whole. So your images will be scaled."

楼主因此运行他们在兼容模式下的应用程序前，图像自动从HVGA扩大到实际的屏幕分辨率;加入的minSdkVersion的图像不再缩小，因此出现了较小的。

The original poster was therefore running their app in this compatibility mode before and the images were automatically scaled up from HVGA to the actual screen resolution; by adding minSdkVersion the images were no longer scaled and therefore appeared smaller.
