我正在开发一个使用许多jpeg图像的应用程序。它总是给出outOfMemory错误异常。然后我尝试解码它。但它仍然给出错误。请帮我解决一下这个。我无法理解错误在哪里。 提前致谢。

答案 0 :(得分：1)
尝试使用Universal Image Loader或Picasso，这些库将帮助您理清OutOfmemory运行时异常，请按照以下步骤操作（使用Picasso）：
1-从这里下载picasso jar文件（http://square.github.io/picasso/）。
2-将jar复制到项目的lib文件夹中。
3-现在右键单击您的jar文件并将其添加到构建路径。
4-现在在您的java src文件中 - 在您的findviewById（R.id.iv12）行之后，删除所有与Bitmap相关的代码（例如，删除所有这些 - mCurrentBitmap，BitmapFactory.Options mBitmapOptions，iv1.setImageBitmap（mCurrentBitmap）; ） 还要从xml文件中删除所有src（例如android：src =“@ drawable / kumana8”）。
5-而是使用：Picasso.with（context）.load（R.drawable.kumana8）.into（imageView1）; 用于以编程方式将drawable设置为imageview。
6-同时尝试在项目的android清单文件中添加android：largeHeapSize =“true”。
此外，您可以从此处（https://github.com/nostra13/Android-Universal-Image-Loader）或其他图像加载库尝试通用图像加载器。
答案 1 :(得分：0)
您将大位图加载到您的应用中。尝试减小位图的大小或添加
android:largeHeapSize="true"
进入你的清单。
答案 2 :(得分：0)
我认为你的图片尺寸很大。你已经用1或2张图片运行了吗？如果您可以运行1或2个错误依赖于图像的图像。您需要减小图像大小。只是我的想法。希望得到帮助。 Compress PNG image tool
答案 3 :(得分：0)
答案 4 :(得分：0)
首先，您需要确定哪些尺寸应具有图像。 我的例子尺寸是1920x1080： 对于地图标记，您可以使用100x100位图。
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeFile(filePath);
int srcWidth = o.outWidth;
int srcHeight = o.outHeight;
int dstWidth = 1920;
int dstHeight = 1080;
int inSampleSize = 1;
if (srcHeight > dstHeight || srcWidth > dstWidth) {
final int halfHeight = srcHeight / 2;
final int halfWidth = srcWidth / 2;
while ((halfHeight / inSampleSize) > dstWidth
&& (halfWidth / inSampleSize) > dstWidth) {
inSampleSize *= 2;
}
}
o.inSampleSize = inSampleSize;
o.inJustDecodeBounds = false;
Bitmap bitmap = BitmapFactory.decodeFile(filePath, o);
此外，您可以使用Bitmap.recycle（）释放内存。
