检查我的应用程序的这个模型： 小样

问题 ：

如果我从第一页点击第二页按钮，它会打开第二页的新意图

然后

我从第二页单击第三页按钮，然后转到第三页

然后

我再次使用第一页按钮进入第一页，然后通过给出以下错误“内存不足... ”使应用程序崩溃

错误 ：

保持堆大小最小；

当您从第 3 页返回时，您可以使用下面的代码来清除活动。

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

或者您可以使用来清除活动。

finish();

或者你可以只传递上下文而不是创建新的

Activity a = (Activity) getContext();

或者你可以使用片段。

我也面临同样的问题，我正在做的事情是跟随。

当您的活动离开其状态并转到其他活动时，它会在成功启动活动2 后调用“onStop()”。所以这样做 

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

当您关闭activity2并返回activity1时，“onResume()将调用。所以这样做，

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

这将解决您的问题。

如果需要，您必须卸载纹理图集并重新加载它们，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();

我希望它能帮助解决您的问题。

确保您正在重用应用程序堆栈中的活动，而不是每次都创建一个新的活动实例。如果不是这种情况，那么应用程序的堆栈肯定会耗尽内存。

android:largeHeap="true"如果您在 AndroidManifest.xml 中添加的图片不多，我想先提两个解决方案 。

或者

使用Outofmemory 解决方案链接加载您的位图，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，看看您的答案是否与现有的一些答案相匹配，那可能是最好的，如果不匹配，请写出使您的情况不同的原因。

将图像加载到 Bitmap 对象时出现奇怪的内存不足问题

由于大位图大小导致内存不足异常

Android处理图像处理内存不足异常
