问题描述
我的 android 应用程序出错.我想使用 viewPager 作为 android 图像滑块，为此我得到了我的 AndroidImageAdapter.java，但是当涉及到方法 instantiateItem 时，应用程序中止，我不知道如何修复它.我已经查找了失败并添加了
I got an error with my android application. I want to use a viewPager as an android image slider, for this I got my AndroidImageAdapter.java, but when it comes to the method instantiateItem the application aborts and I don't know how to fix it. I already looked up the failure and added
android:hardwareAccelerated="false"
android:largeHeap="true"
到我的清单，但它仍然存在.这是完整的错误代码:
to my manifest, but it still remains. Here is the complete error code:

推荐答案
571401228 字节相当于 11952 x 11952 像素图像.这太大了.
571401228 bytes is the equivalent of 11952 x 11952 pixel image. This is much too large.
问题很可能有两个方面:
Most likely, the problem is two-fold:
drawable 资源本身的分辨率太大
The drawable resource's resolution is too large in its own right
您将图像放在 res/drawable/ 中，因此它会根据您的实际设备密度进行放大，因此它比您开始时大 4 倍或 8 倍p>
You put the image in res/drawable/, and so it is being upscaled based on your actual device density, so it is 4x or 8x larger than what you started with
不要将位图放在 res/drawable/ 中，它是 res/drawable-mdpi/ 的同义词.为各种密度创建与密度相关的绘图版本，或者将此绘图放在 res/drawable-anydpi/ 中.另外，请确保分辨率合理.
Do not put bitmaps in res/drawable/, which is a synonym for res/drawable-mdpi/. Either create density-dependent editions of the drawables for various densities, or put this drawable in res/drawable-anydpi/. Also, make sure that the resolution is reasonable.
