问题描述

我有一个启动一个活动的的AsyncTask （称为WorkerClass），并从AsyncTask的我添加一个 BaseAdapter 我的 GridView控件：

I have an activity which starts an asynctask(called WorkerClass) and from the asynctask i add an BaseAdapter to my GridView:

我从我的活动启动AsyncTask的：

I start the AsyncTask from my Activity:

if(gallery == null || switchScaleMode == true) {
            myWorkerClass = new WorkerClass(myActivity.this, width, scaleButtonText);
            myWorkerClass.execute();
        }

画廊是显示图像在我的GridView的可绘制列表。我知道这是非常糟糕的把整个活动的背景下另一个类..但我需要它来获取在 WorkerClass（AsyncTask的）访问2次。所以我的第一个问题，它会prevent我的内存泄漏，如果我只是把2次到 WorkerClass ，而不是整个活动？

Gallery is a drawable List which Shows Image in my gridview. I know it's really bad to put the whole activity context to another class.. But i Need it to get Access to 2 views in the WorkerClass(AsyncTask). So my first question, would it prevent my Memory leak if i just put the 2 views to the WorkerClass instead of the whole activity?

为什么我知道我有一个内存泄漏我的应用程序？

我开始更新堆在DDMS我的应用程序进程，得到了如下结果：

I started Update Heap in the DDMS for my APP-Process and got following results:

在启动至完全加载：

对于我来说，这看起来像一个HIGHT量，如果有> 90％开始后内存使用。

For me this Looks like a hight amount if there is >90% of Memory usage after start..

现在，当我转动我的设备好几次我得到这个：（通知：我只启动 WorkerClass 并添加适配器到 GridView控件有一次，在启动时。因为我不希望重新计算（将图像等），每次用户旋转（时间consumpting）。

Now when i rotate my device several times i get this:(notice: i only launch the WorkerClass and adding the Adapter to the GridView one time, at Startup. Because i don't want to recalculate(getting Images and so on) every time user is rotating (time consumpting).

所以，如果我再次旋转我的设备并再次我得到了一个AsyncTask的内存溢出异常。即使是我只有一次启动它。（所以必须有一个对象，它会导致OOM ??的娱乐某种）

So, if i rotate my device again and again i get a Out Of Memory exception in the AsyncTask. Even that i only start it once.. (so there must be some Kind of recreation of an object which cause a OOM ??)

我不明白的是，如果我超过了DDMS按钮 GC 做GC我得到：

What i don't understand is that if i do a GC over the Button GCin the DDMS i get:

因此，这是使用我的进程的内存量有所增加？但不应该在GC释放使用的内存？

So the amount of Memory which is used by my process has increased? But shouldn't the GC releasing used Memory?

最后一个问题：我试图从日食是 MAT （内存分析工具）的工作。但是，这只是启动后，工作在 DDMS 我的应用程序。如果我服用堆转储前几次旋转快照日食并不做任何事情。没有错误，也没有动作。我唯一注意到的是，我无法启动堆转储再次出现以下错误：

The last Problem: I tried to work with MAT (Memory Analyzer Tool) from eclipse. But this only works after Startup my app in the DDMS. If i rotate it several times before taking a Heap Dump "Snapshot" eclipse doesn't do anything. No error, but also no Action. Only Thing i noticed is that i can't start Heap Dump again with the following error:

12-07 15:09:52.739: E/jdwp(1109): Failed sending b-req to debugger: Invalid argument (67536832 of 96983113)
12-07 15:09:53.759: E/jdwp(1109): Failed sending reply to debugger: Try again

请理解，我并不怎么让我的整个code公众。如果你告诉我你想看到我会尽我所能，具体是什么..

Please understand that i don't what to make my whole code public. If you tell me specifically what you want to see i'll try my best..

更新

所以，现在我有一个堆转储一些旋转后，这是输出：

So now i got a Heap Dump after some rotates and this is the Output:

我实例化的EditText和GridView在我的活动，并在我的 WorkerClass 。因为这些都是我在 WorkerClass 为什么我把我的活动 - 语境极品仅有的两个意见 WorkerClass 。

I instantiate EditText and GridView in my Activity and in my WorkerClass. Because These are the only two views which i Need in my WorkerClass and why i put my Activity-Context to the WorkerClass.

所以将它解决我的问题是，如果声明并仅在活动实例并将其传递给 WorkerClass 。

So will it solve my Problem is if declare and instantiate them only in the Activity and pass them to the WorkerClass.
