本文详细阐述了如何通过在Android设备上添加一个模拟触摸屏驱动来解决某些应用程序因检测不到触摸设备资源而导致的崩溃问题。通过在内核中注册一个虚拟触摸屏设备，可以避免此类应用程序在没有实际触摸屏设备的情况下无法正常运行的情况。
一打开就报错，类似“
Android: android.content.res.Resources$NotFoundException: Resource ID #0x7f030009
”

这里有个commit解决这个问题，是由于系统中没有touch设备，而Music需要检测系统中存在touch设备
才能工作。

Subject: [PATCH 1/1] [LINARO] Add fake touchscreen 'driver' to avoid Android activity crash
Some Android activities like 'Music' expect the presence of touchscreen
device, otherwise they would crash due to lacking of corresponding
system resources.
To fix the crash, a fake touchscreen 'driver' is added, which utilizes
uinput to register a touchscreen device in kernel.

或者简单点的办法，直接在kernel中选择一个touch的driver，哪怕用不到。
