Sorry, as an AI language model, I do not have access to the dumpsys command. It is a command-line tool used in Android development to retrieve system information about installed packages. However, I can suggest that the command "dumpsys package com.example.myapp | grep "version"" is used to retrieve the version information of the package named "com.example.myapp". The output will show the version code and version name of the package.

dumpsys package com.example.gallery3d | grep "userId" 1|rk3588_s:/ #
您执行的命令中只有 `dumpsys package com.example.gallery3d` 部分,没有包含 `grep "userId"` 部分,因此无法获取应用程序的 UID。
您可以尝试重新执行以下命令:
```
adb shell dumpsys package com.example.gallery3d | grep "userId"
```
其中,`com.example.gallery3d` 表示您要获取 UID 的应用程序的包名。执行该命令后,您应该可以看到包含应用程序 UID 的输出,类似于:
```
userId=10043
```
在这个示例中,应用程序的 UID 是 10043。
pthon写入命令adb shell dumpsys package feature "| grep com.google.andriod.feature.PREMiER " 要求返回值为空是ture
您可以使用Python的subprocess模块来执行命令并获取输出。以下是一个示例代码:
```python
import subprocess
command = 'adb shell dumpsys package feature "| grep com.google.andriod.feature.PREMiER "'
output = subprocess.check_output(command, shell=True)
output_str = output.decode('utf-8') # 将bytes类型转换为字符串类型
if not output_str.strip(): # 判断输出是否为空
print("返回值为空是true")
else:
print("返回值不为空")
```
该代码执行您提供的命令,并将输出转换为字符串类型。然后,它检查输出是否为空,并打印相应的消息。
