本文详细介绍了如何解决Android设备中动态库加载问题、HDMI接口移植问题、网路服务错误等常见问题。通过分析日志和错误代码，提供了解决方案和配置建议，帮助开发者高效解决问题。

1）动态库加载问题，constant

libsensor，liblight

05-31 00:44:10.654 I/DEBUG   ( 2048): backtrace:^M
05-31 00:44:10.654 I/DEBUG   ( 2048):     #00 pc 00000784 /system/lib/libhardware.so (hw_get_module_by_class+359)^M
05-31 00:44:10.654 I/DEBUG   ( 2048):     #01 pc 0000f643 /system/lib/libsensorservice.so (android::SensorDevice::SensorDevice()+102)^M
05-31 00:44:10.654 I/DEBUG   ( 2048):     #02 pc 0000f045 /system/lib/libsensorservice.so (android::Singleton<android::SensorDevice>::getInstance()+32)^M
05-31 00:44:10.654 I/DEBUG   ( 2048):     #03 pc 0001178f /system/lib/libsensorservice.so (android::SensorService::onFirstRef()+22)^M
05-31 00:44:10.654 I/DEBUG   ( 2048):     #04 pc 0000ef5d /system/lib/libutils.so (android::RefBase::incStrong(void const*) const+38)^M

2)hdmi porting，之前错误是分支选错引起，hdmi要点移除surfacefinger client依赖。

分辨率 solution 参考:

Device Driver
Multimedia support --->
Video Capture Adapters --->
HDMI HPD driver support.

3)netd error ,可能需要重新编译内核

4）kernel porting

错误1
kernel/drivers/net/wireless/bcm4329/wl_iw.c: In function 'wl_iw_set_pmksa':
kernel/drivers/net/wireless/bcm4329/wl_iw.c:5438:5: error: array subscript is above array bounds [-Werror=array-bounds]
kernel/drivers/net/wireless/bcm4329/wl_iw.c:5441:5: error: array subscript is above array bounds [-Werror=array-bounds]

参考

https://github.com/Jhinta/TF101-GNU-kernel/issues/1
Remove -werror from make file
or Compile the code with the –Wno-array-bounds switch

错误2
drivers/media/video/samsung/tv20/s5p_stda_grp.c
602,605
使用中间变量赋值

config中加入如下配置，可以解决Netd中 iptable错误。
