1

push了一个GPS的动态库后，设备重启后，一直在开机动画，界面出不来
不知是什么问题，又遇到此情况的，快来帮帮我，谢谢啦

2

为什么没有动静，好郁闷{:4_177:}

3

不知道你在说什么，没log信息怎么看

4

I/DEBUG ( 138): #00 pc 000007c2 /system/lib/libhardware.so (hw_get_module_by_class+365)
库模库初始化有问题吧，要自己分析代码了

I/DEBUG ( 138): #00 pc 000007c2 /system/lib/libhardware.so (hw_get_module_by_class+365)
库 …

/system/lib/libhardware.so是这个库的问题吗？
我push进去的是/system/lib/hw/gps.default.so，开机就是这样的情况。
能看出来具体是哪里的问题吗？

谢谢喽！问题已经找到啦！

const struct hw_module_t HAL_MODULE_INFO_SYM = {
.tag = HARDWARE_MODULE_TAG,
.version_major = 1,
.version_minor = 0,
.id = GPS_HARDWARE_MODULE_ID,
.name = “HZZKW GNSS Module”,
.author = “Jarod Lee”,
.methods = &gps_module_methods,
};
我想问问这写编两的赋值在哪里？依据什么赋值？

这个是我的hardware.c的文件，还是有问题，不知道哪里的问题
