使用Android11的环境，添加GPS模块。
RK3568开发板使用默认固件0812版本，GPSiTset apk。使用贵公司发布的固件测试GPS模块，有报错。另外自己添加gps.default.so也有报错。下面列出了两个报错，望高手指点，万分感谢。
（1）使用2021.8.12 发布的固件版本，gps有报错，如下

（2）新增gps.default.so文件。报错如下：

2.新增gps.default.so 位置是否正确，自己的gps.default.so 放到/vendor/lib/hw/和/vendor/lib64/hw/ 问题已经解决：
1. firefly 已经实现 GNSS1.0
2. 使用自己开发的gps.default.so文件，每个函数都要实现，不能为空。否则crash luwy 发表于 2022-2-9 09:16

请问是怎么添加自己的gsp.default.so的呢，新手不太懂这些，我现在编译出来一个gps.90.so,位置也在vendor目录下的对应位置，开机的时候没有进入这个判断, private void loadProvidersLocked() {
// create a passive location provider, which is always enabled
PassiveProvider passiveProvider = new PassiveProvider(this);
addProviderLocked(passiveProvider);
mEnabledProviders.add(passiveProvider.getName());
mPassiveProvider = passiveProvider;
Log.e(TAG, "in locationMS GnssLocationProvider.isSupported()=" +GnssLocationProvider.isSupported());
if (GnssLocationProvider.isSupported()) {
// Create a gps location provider
Log.e(TAG, "in location MSloadProvidersLocked add GPS Provider");
GnssLocationProvider gnssProvider = new GnssLocationProvider(mContext, this,
mLocationHandler.getLooper());
mGnssSystemInfoProvider = gnssProvider.getGnssSystemInfoProvider();
mGnssBatchingProvider = gnssProvider.getGnssBatchingProvider();
mGnssMetricsProvider = gnssProvider.getGnssMetricsProvider();
mGnssStatusProvider = gnssProvider.getGnssStatusProvider();
mNetInitiatedListener = gnssProvider.getNetInitiatedListener();
addProviderLocked(gnssProvider);
mRealProviders.put(LocationManager.GPS_PROVIDER, gnssProvider);
mGnssMeasurementsProvider = gnssProvider.getGnssMeasurementsProvider();
mGnssNavigationMessageProvider = gnssProvider.getGnssNavigationMessageProvider();
mGpsGeofenceProxy = gnssProvider.getGpsGeofenceProxy();
}，开机后无法使用GPS 测试没有provider 可以参考一下这个帖子：https://blog.csdn.net/halazi100/article/details/107065326/ 本帖最后由 bzhao 于 2022-5-28 18:00 编辑
楼主问题应该是这样 ,缺少hidl gnss的说明， 就像在Manifest.xml没有说明的类是不能被注册进去的,
device/rockchip/rk3399/manifest.xml:
it should have the section like:
<hal format="hidl">
<name>android.hardware.gnss</name>
<transport>hwbinder</transport>
<version>1.0</version>
<interface>
<name>IGnss</name>
<instance>default</instance>
</interface>
</hal>
请教下给开发板添加GPS模块有相关得教程吗？
