Android 应用程序在 2.3 设备上运行，在 4.1 上崩溃(重新发布)

Question

我有一个 Android 应用程序可以在 2.3 版设备和一个特定的 4.1 模拟器上完美运行。它在其他 4.1 模拟器和 4.1 Google Nexus 设备上崩溃。

有什么想法吗？

这与尺寸、分辨率等有什么关系吗？

这是我在 4.1 模拟器上运行时的 logcat 输出。实际上代码很大，所以不能真正把它放在这里。任何提示都会很棒。然后我可以提供所需的代码 fragment 。

您是否尝试在 list 文件中应用应用的 SDK 版本范围？

例如像这样的行:

<uses-sdk android:minSdkVersion="7" android:maxSdkVersion="15"/>
