【问题描述】：
我决定重新输入问题，因为我对问题有了更深入的了解：
嗨， 我很绝望！请帮我！我在这个应用上投入了这么多时间，但自从 2 周以来一直找不到解决这个问题的方法！
应用说明： 我使用 LibGdx 引擎为 android 开发了一个应用程序。这是一个跳跃和奔跑的游戏。在此，Box2d 正在建模物理，渲染平铺地图，对象解析器正在创建对象，所有数据都由资产管理器管理，包含菜单/HUD 表格的阶段 - 如有必要，请询问更多详细信息！
问题描述（该错误仅（！）发生在真实设备上（是的 - 我尝试了不止一个设备））： 玩了一些关卡后，应用程序突然被推到后台，没有任何通知或其他东西。通过任务管理器恢复应用程序后，应用程序将重新启动。这会在几分钟后随机发生。
“API-USB-Debug-mode”中的Logcat-output：
当应用程序崩溃时，app-pid 没有特定错误 - 询问您是否仍然感兴趣！
此系统范围的输出总是在崩溃发生前几秒钟出现：
01-29 21:07:51.915: W/InputDispatcher(2345): channel '421c2b38 com.android.launcher3/com.android.launcher3.Launcher (server)' ~ Consumer closed input channel or an error occurred. events=0x9
01-29 21:07:51.915: E/InputDispatcher(2345): channel '421c2b38 com.android.launcher3/com.android.launcher3.Launcher (server)' ~ Channel is unrecoverably broken and will be disposed!

在此行之后，应用程序总是崩溃并打印以下行：

原始 logcat 中有很多噪音。哪些行来自您的应用程序？ （它的名称和/或 pid 是什么？）参见 stackoverflow.com/questions/6405422/logcat-filtering。您的游戏是否使用输入设备？ （屏幕键盘？）有什么有趣的设置吗？你在你的应用中做任何网络吗？
-
谢谢！我编辑了关于 logcat 输出的线程！我不使用网络，没有屏幕键盘或任何有趣的设置......
-
你确定“/storage/emulated/0/Android/data/com.touchtype.swiftkey/files/parameters.json”的“无法读取参数文件”完全不相关吗？根据@ 987654322@ 这是一个 SwiftKey 问题，似乎也偶尔发生。
-
谢谢！是的...我很确定，因为崩溃也发生在我兄弟没有使用 Swift Key 的设备上...
