LibGDX Android 只申请一次 运行
LibGDX Android Application only running once
我无法弄清楚为什么我的 LibGDX 游戏在 Android.
上仅 运行 成功一次
假设游戏还没有安装在设备上，当我 运行 从 eclipse 应用程序时，游戏 运行 没问题。关闭游戏后，并尝试通过在我的 phone 上打开游戏（不是通过 eclipse）再次 运行 游戏，它似乎永远挂在这个屏幕上：
根据我的测试，我发现我的 Android 启动器代码中的 none 被执行，.onCreate() 从未被调用。 LogCat 显示没有抛出任何错误，应用程序似乎只加载了 LibGDX 库，然后什么也没有。这是整个 LogCat 输出：http://i.imgur.com/5DQ5sHY.png
在 LogCat 中唯一让我大吃一惊的是：
Launch timeout has expired, giving up wake lock!
Activity idle timeout for ActivityRecord
有时清除设备上游戏的缓存和数据似乎可以暂时解决问题，但并非总是如此。
这是Android启动器class：

根据 LogCat 的输出，我不知道问题出在哪里。我已经在 Xperia U 和 Xperia Z1 上对此进行了测试，但问题仍然存在。感谢您的帮助。
编辑 - 额外信息：
我正在使用 LibGDX (1.5.4)
的最新版本
经过几天的紧张，我终于解决了这个问题。在主线程上执行回溯后，我发现程序在尝试加载 Google Analytics 跟踪器时停止了。这是线程回溯：
at com.google.android.gms.analytics.ae.getLogger(Unknown Source)
at com.google.android.gms.analytics.ae.W(Unknown Source)
at com.google.android.gms.analytics.z$a.f(Unknown Source)
at com.google.android.gms.analytics.n.a(Unknown Source)
at com.google.android.gms.analytics.n.x(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.eZ(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.getInstance(Unknown Source)
然后我对这个结果做了一些研究。这似乎是尝试从 xml 文件加载跟踪器时导致的错误。此处更详细地讨论了此错误：
- Google Analytics blocks Android App
- https://code.google.com/p/analytics-issues/issues/detail?id=552
为了防止这个错误，我不再通过删除 AndroidManifest.xml:
中的这一行来从相应的 xml 文件中加载跟踪器
<meta-data
android:name="com.google.android.gms.analytics.globalConfigResource"
android:resource="@xml/analytics_global_config" />
问题已解决，谢谢大家。

这是我的 AndroidManifest.xml:

根据 LogCat 的输出，我不知道问题出在哪里。我已经在 Xperia U 和 Xperia Z1 上对此进行了测试，但问题仍然存在。感谢您的帮助。
编辑 - 额外信息：
我正在使用 LibGDX (1.5.4)
的最新版本经过几天的紧张，我终于解决了这个问题。在主线程上执行回溯后，我发现程序在尝试加载 Google Analytics 跟踪器时停止了。这是线程回溯：
at com.google.android.gms.analytics.ae.getLogger(Unknown Source)
at com.google.android.gms.analytics.ae.W(Unknown Source)
at com.google.android.gms.analytics.z$a.f(Unknown Source) at com.google.android.gms.analytics.n.a(Unknown Source)
at com.google.android.gms.analytics.n.x(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.eZ(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.(Unknown Source)
at com.google.android.gms.analytics.GoogleAnalytics.getInstance(Unknown Source)
然后我对这个结果做了一些研究。这似乎是尝试从 xml 文件加载跟踪器时导致的错误。此处更详细地讨论了此错误：
- Google Analytics blocks Android App
- https://code.google.com/p/analytics-issues/issues/detail?id=552
为了防止这个错误，我不再通过删除 AndroidManifest.xml:
中的这一行来从相应的 xml 文件中加载跟踪器<meta-data
android:name="com.google.android.gms.analytics.globalConfigResource"
android:resource="@xml/analytics_global_config" />
问题已解决，谢谢大家。
