Cho*_*Yan 5 android android-manifest android-emulator
Posted my problem here too.
A beginner..I am doing a school map app.
First of all I have background with 4 buttons ( level3, level4, level5, level6).
I try and click all the buttons, normally after clicking 3 of it, the next one will crash.(each level button goes into a level map, whereby clicking the room image buttons, I will enter into the gallery-imageswitcher)
I have at least 5 ImageSwitchers in each level maps,so that about over 20 ImageSwitcher galleries overall.
I did all my stuffs using Drawable instead of Bitmap. I have tons and tons of images (because its a school map, show all the photos in my school, and all those backgrounds and ImageButton)
我做了一些研究,那些有问题的人是那些使用位图的人.可以解决的一些方法是system.gc();,bitmap.recycle(并不确定如何使用它)

真的很感激,如果有人可以提供帮助......谢谢
PS:我在应用程序中有大量图像.我ImageSwitcher每个级别至少有5个画廊,所以在我的应用程序中有20多个图像处理器.
我必须在这里做一些猜测，因为您的命名和行号并不真正匹配。
例如，您有这一行：
startActivity(new Intent("android.com.Lvl4"));
但您的活动名为“android.com.Level4”。当您将布局“tlevel4”称为“level4.xml”时，您正在膨胀布局“tlevel4”。另外，您粘贴的错误适用于 Level3。也许它们很相似，但行号很重要，所以最好发布相同的错误和类。
我并不是想挑剔，这些细节只是在尝试破译您不熟悉的代码时产生很大的不同。
无论如何，在这种情况下，我认为发生的事情已经很清楚了。
错误 1 和 2 这两个错误都是内存不足异常。在这两种情况下，您都要求操作系统为您提供内存来加载一些大型资源，而操作系统只是告诉您您已经受够了。如果您发现这种情况持续发生，则几乎可以肯定您在某处泄漏了内存。您提到广泛使用可绘制对象。您要非常小心地处理这些内容，因为当您将可绘制对象添加到视图时，它会保留对视图的引用...它具有对 Context 的引用。我在您发布的代码中没有看到任何明显的明显内容，但我敢打赌您有某种上下文泄漏。阅读这篇文章，看看他们谈论的任何内容是否引起您的注意。
另外，我注意到您的包名称是 android.com （即 android.com.Lvl3）。也许您只是为了发布而编辑了此内容，但它实际上应该以 com 开头，即 com.yourProjectName.Lvl3。
哦，请不要这样做：
startActivity(new Intent("android.com.Android"));
只需调用 this.finish();
