为什么我的带有 TabGroup 的 Titanium Android 应用程序存在内存和性能问题？
Why does my Titanium Android app with TabGroup having memory and performance issues?
我在 Titanium 中有一个 iOS 应用程序，现在我想创建 Android 版本。
我的问题是在Android我有很多内存问题和性能问题。
该应用程序包含一个包含三个选项卡的选项卡组。在每个选项卡中都有按钮（以及图像和信息），可让您转到另一个子window。我什至可以达到 subwindows 的 3 或 4 级。它还具有四个包含大量数据的数据库。
在 iOS 我使用：self.containingTab.open(new AddWindow); 每次我想进入另一个级别时，它允许您向后导航到上一个 window。在 Android 上，当按下硬件后退按钮时，我也可以返回到之前的 window，但我有很多内存不足错误。
难道是因为我打开新的windows和旧的windows还在吃内存？管理具有多个选项卡的选项卡组以及每个选项卡允许您转到不同子 windows 的最佳方式是什么？
我试过创建一个视图并添加到旧的 window，而不是创建一个 window，但是我无法返回到以前的视图，尽管我自己管理它.
有更好的方法吗？
非常感谢！

这是我收到的错误：
首先我有一些：
Unable to load bitmap. Not enough memory: Failed to allocate a
10731532 byte allocation with 9611988 free bytes and 9MB until OOM
然后，一些：
Throwing OutOfMemoryError "Failed to allocate a 10731532 byte
allocation with 5437592 free bytes and 5MB until OOM"
但应用程序仍然有效。
直到我收到：

并且应用程序崩溃。
更新
因为该应用程序是基于以前的 iOS 应用程序。它真的很大，尝试在这里放一些代码很复杂。但我将尝试解释它的组成部分：
首先，它会打开一个选项卡组，我在其中创建了四个不同的选项卡。应用程序创建每个选项卡需要很长时间。
1 标签：这是一个主页标签，它包含 link 其他标签。每个 link 都是一张图片。我将 link 创建为 ImageView。此 window 还包含一个背景图片。 （图片放在ImageView里好还是放在backgroundImage里好？对内存和性能有影响吗？）
2、3 和 4 选项卡：包含更多 link 和许多子级别。我将解释我所遵循的使应用程序崩溃的过程（每个 link 包含一个带有背景颜色的视图、一个标签和一个带有 brackgroundGradient 的按钮）：
- 转到选项卡 2，出现了一个新的 window 和 3 个不同的 link
- 转到link 1：它出现另一个window 6 links
- 转到link 1：出现另一个window，有两个tablesView。左边一排（5 行），右边一排大约 20 行。在右侧 table 每行都有一个图像和两个标签添加到 tableviewrow。
问题似乎与图像有关，给出错误：
Unable to load bitmap.
请检查您使用的图像的尺寸。您是否提供特定于 dpi 的变体，以便在较小的设备上您不会加载太大的图像？你会尽可能使用九补丁图像吗？另请注意，在 TabGroup 中，所有主要级别 Windows 始终处于打开状态。如果它们都有大图像，您应该使用每个选项卡的 (un)selected 事件来（卸载）加载图像。
我在 Titanium 中有一个 iOS 应用程序，现在我想创建 Android 版本。
我的问题是在Android我有很多内存问题和性能问题。
该应用程序包含一个包含三个选项卡的选项卡组。在每个选项卡中都有按钮（以及图像和信息），可让您转到另一个子window。我什至可以达到 subwindows 的 3 或 4 级。它还具有四个包含大量数据的数据库。
在 iOS 我使用：self.containingTab.open(new AddWindow); 每次我想进入另一个级别时，它允许您向后导航到上一个 window。在 Android 上，当按下硬件后退按钮时，我也可以返回到之前的 window，但我有很多内存不足错误。
难道是因为我打开新的windows和旧的windows还在吃内存？管理具有多个选项卡的选项卡组以及每个选项卡允许您转到不同子 windows 的最佳方式是什么？
我试过创建一个视图并添加到旧的 window，而不是创建一个 window，但是我无法返回到以前的视图，尽管我自己管理它.
有更好的方法吗？
非常感谢！

并且应用程序崩溃。
更新
因为该应用程序是基于以前的 iOS 应用程序。它真的很大，尝试在这里放一些代码很复杂。但我将尝试解释它的组成部分：
首先，它会打开一个选项卡组，我在其中创建了四个不同的选项卡。应用程序创建每个选项卡需要很长时间。
1 标签：这是一个主页标签，它包含 link 其他标签。每个 link 都是一张图片。我将 link 创建为 ImageView。此 window 还包含一个背景图片。 （图片放在ImageView里好还是放在backgroundImage里好？对内存和性能有影响吗？）
2、3 和 4 选项卡：包含更多 link 和许多子级别。我将解释我所遵循的使应用程序崩溃的过程（每个 link 包含一个带有背景颜色的视图、一个标签和一个带有 brackgroundGradient 的按钮）：
- 转到选项卡 2，出现了一个新的 window 和 3 个不同的 link
- 转到link 1：它出现另一个window 6 links
- 转到link 1：出现另一个window，有两个tablesView。左边一排（5 行），右边一排大约 20 行。在右侧 table 每行都有一个图像和两个标签添加到 tableviewrow。
问题似乎与图像有关，给出错误：
Unable to load bitmap.
请检查您使用的图像的尺寸。您是否提供特定于 dpi 的变体，以便在较小的设备上您不会加载太大的图像？你会尽可能使用九补丁图像吗？另请注意，在 TabGroup 中，所有主要级别 Windows 始终处于打开状态。如果它们都有大图像，您应该使用每个选项卡的 (un)selected 事件来（卸载）加载图像。
