setContentView上的Android内存不足

标签： android

我制作了一个有6个屏幕的全屏点击应用程序。点击后该应用程序从屏幕进入。每个屏幕都有自己的活动（步骤1，步骤2，步骤3等，直到步骤6）。没有什么复杂的，布局非常简单，只有背景图像和按下按钮。当问题开始时我会看到屏幕3，突然下一个屏幕不会显示，但应用程序崩溃，内存不足错误。我尝试过移动到屏幕4,5,6，没有运气，但如果我从屏幕3移回屏幕2，那么它可以工作！有什么东西泄漏，但我不知道是什么。背景图片很小。

我正在使用此代码更改活动：

Intent myIntent = new Intent(Step3.this, Step6.class); 
Step3.this.startActivity(myIntent); 
System.gc();

这是日志：

编辑：我创建了一个类似六个屏幕的应用程序，只有textview和一个按钮和一个导航链（1 - ＆gt; 2 - ＆gt; 3 - ＆gt; 4 - ＆gt; 5 - ＆gt; 6 - ＆gt; 1）没有任何图像，它像黄油一样工作。 （如预期的那样）。所以这绝对与占用大量内存的图像有关。

2 个答案:

答案 0 :(得分：2)

要注意的一些事项。

  • 您是否提供了几种密度的背景图片？缩放有时会占用大量内存。
  • 您使用startActivity还是startActivityForResult()？在后一种情况下，不能销毁旧的Activity对象。
  • 您是否在Application班级收集信息？

答案 1 :(得分：1)

只要您离开活动去另一个并重新排序代码，就会

recycle()您的位图：

bitmap.recycle();
System.gc();
Intent myIntent = new Intent(Step3.this, Step6.class); 
Step3.this.startActivity(myIntent);
