使用 parse.com 并有内存分配问题
Using parse.com and having allocation memory issue
我是编程新手，过去 3 个月我一直在制作应用程序并学到了一些东西。但是我还没有想到如何解决这个问题。我一直在使用 Parse.com 作为我的服务器，发送图片，保存用户数据等。有了所有这些数据，如果我多次打开某些活动，尤其是带有图片的活动，应用程序就会崩溃。现在我已经压缩了图片并使它们的分辨率最大为 400x400。但是不知何故分配内存不足不断弹出。有谁知道可以解决这个问题的方法吗？因为当应用程序在 Android Studio 中崩溃时，我 phone 上的先前内存似乎被删除了（不是所有的缓存数据）。
谢谢。

代码太长，不能放在这里，因为它限制在 30,000 个字符内
如果您正在使用 parse.com 并从数据库中获取图像并将其转换为位图，它会使您的应用程序崩溃..
你应该做的是，从 parse.com 中获取 URL 的图像，有一个方法叫做..
ParseFile.getUrl();
为此实现 Picasso 库，这是从数据库加载图像的完美解决方案。
要在您的应用中实施 picasso，
compile 'com.squareup.picasso:picasso:2.5.2'
然后从解析数据库中获取文件
ParseFile file = getParseFile("ImageColumn");
加载文件
Uri url = Uri.parse(file.getUrl());
然后获取上下文并..添加以下传递您的文件url..
Picasso.with(context)
.load(url) //load from your URL of parseFile
.into(imageView); //set it to your ImageView
这就是为什么你应该实施这个的原因..
Getting Bitmap file will consume so much memory, and it will give you
OutOfMemory Exception, which you are getting right now. So instead you
just get the URL of file and that's it. Loading image will be
dependent on the Internet. so you are saving the memory by not converting
every single bit into image.
Also you will do in loop for every image will cause your app to crash.
另外完整的教程将在官方网站上提供

我是编程新手，过去 3 个月我一直在制作应用程序并学到了一些东西。但是我还没有想到如何解决这个问题。我一直在使用 Parse.com 作为我的服务器，发送图片，保存用户数据等。有了所有这些数据，如果我多次打开某些活动，尤其是带有图片的活动，应用程序就会崩溃。现在我已经压缩了图片并使它们的分辨率最大为 400x400。但是不知何故分配内存不足不断弹出。有谁知道可以解决这个问题的方法吗？因为当应用程序在 Android Studio 中崩溃时，我 phone 上的先前内存似乎被删除了（不是所有的缓存数据）。
谢谢。
