Android 出现问题Installation error: INSTALL_FAILED_CONFLICTING_PROVIDER解决办法
这个错误通常是因为在启动 `robot_state_publisher` 节点时找不到 `state_publisher` 可执行文件。你可以尝试以下几个步骤解决这个问题:
1. 确认 `robot_state_publisher` 软件包已经安装并且已经编译,你可以使用 `rospack` 命令来检查一下:
```
$ rospack find robot_state_publisher
```
2. 检查 `state_publisher` 可执行文件是否存在并且已经设置为可执行权限,你可以使用以下命令检查:
```
$ ls -l $(rospack find robot_state_publisher)/bin/state_publisher
```
如果文件不存在或者没有可执行权限,你可以使用以下命令添加可执行权限:
```
$ chmod +x $(rospack find robot_state_publisher)/bin/state_publisher
```
3. 如果上述步骤都没有解决问题,你可以尝试重新编译软件包并重新启动节点:
```
$ cd <catkin_workspace>
$ catkin_make
$ source devel/setup.bash
$ roslaunch <your_launch_file>.launch
```
