问题描述

我的Android应用程序出错了。
我想使用viewPager作为android图像滑块，为此我得到了我的AndroidImageAdapter.java，但是当涉及方法instantiateItem时，应用程序中止，我不知道如何解决它。
我已查找失败并添加

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。
以下是完整的错误代码：

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.

最有可能的问题是双重问题：

Most likely, the problem is two-fold:


  • 可绘制资源的分辨率本身太大

  • The drawable resource's resolution is too large in its own right

您将图像放入 res / drawable / ，因此它会根据您的实际设备密度进行升级，因此它比您开始时大4倍或8倍

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，这是 res / drawable-mdpi /的同义词。要么为各种密度创建与drawables密度相关的版本，要么将此drawable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.
