在Android应用程序中VM已满时，如何克服OutOfMemoryError？

时间：2013-05-14 06:46:22

标签： android bitmap out-of-memory virtual-memory

检查我的应用程序的MOCKUP： Mockup

问题：

如果我点击第一页上的第二页按钮，它会打开第二页的新意图

然后

我点击SECOND PAGE中的 THIRD PAGE 按钮，然后转到第三页

然后

我再次使用FIRST PAGE BUTTON 然后崩溃应用程序进入 FIRST PAGE ，给出以下错误“ 内存不足.... “

错误：

如果有人知道然后分享你的答案，那么我就可以解决它。

谢谢。

5 个答案:

答案 0 :(得分：0)

确保您重复使用应用程序堆栈中的活动，而不是每次都创建活动的新实例。如果不是这样的话那么应用程序的堆栈肯定会耗尽内存。

答案 1 :(得分：0)

我也面临同样的问题，我正在做的是跟随。

当您的活动离开其状态并转到其他活动时，它会在成功启动 activity2 后调用“onStop（）”。这样做

@Override
protected void onStop() 
{
    relativeLayout.setBackgroundDrawable(null);
}

当你关闭 activity2 并返回 activity1 时，“onResume（）会调用。所以这样做，

@Override
protected void onResume() 
{
    relativeLayout.setBackgroundResource(R.drawable.home_bg);
}

这将解决您的问题。

答案 2 :(得分：0)

您必须卸载纹理图集并在需要时重新加载它们，否则肯定会产生内存不足错误。
以下是如何卸载纹理以释放内存：

    // all the textures you think are big      
    Engine.getTextureManager().unloadTexture(bg); 
    bg.clearTextureAtlasSources();    
    System.gc();

我希望这有助于解决您的问题。

答案 3 :(得分：0)

我想首先提一下两个解决方案，如果您使用的是不太重的图片，请在AndroidManifest.xml中添加android:largeHeap="true"。

或

使用Outofmemory solution链接加载您的位图，并在切换活动时回收该位图。它的常见问题及其解决方案多次在stackoverflow中提供。

如果您查看现有问题的答案，看看您的问题是否与现有问题相匹配，那么最好的情况可能是最好的，如果不匹配，请写出使您的情况不同的原因。

Strange out of memory issue while loading an image to a Bitmap object

Out of memory exception due to large bitmap size

Android handling out of memory exception on image processing

答案 4 :(得分：0)

将堆大小保持在最低限度;

当您从第3页返回时，您可以使用下面的代码清除活动。

Intent intent = new Intent(getActivity(), MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//to clear previous activities                      
startActivity(intent);

或者您可以用来清除活动。

finish();

或者您只需传递上下文而不是创建新的

Activity a = (Activity) getContext();

或者您可以使用fragments。
