要优化Python ADB命令的性能,可以采取以下措施:
-s
选项来实现。例如:import subprocess
commands = [
"adb -s device_id install app.apk",
"adb -s device_id shell input tap 100 200",
"adb -s device_id pull /sdcard/file.txt ./file.txt"
]
subprocess.run(commands, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
threading
或multiprocessing
库来并行执行这些命令。这样可以显著提高性能,因为每个命令将在单独的线程或进程中运行。import threading
import subprocess
def run_command(command):
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate()
if process.returncode != 0:
print(f"Error: {stderr.decode('utf-8')}")
else:
print(stdout.decode('utf-8'))
commands = [
"adb -s device_id install app.apk",
"adb -s device_id shell input tap 100 200",
"adb -s device_id pull /sdcard/file.txt ./file.txt"
]
threads = []
for command in commands:
thread = threading.Thread(target=run_command, args=(command,))
thread.start()
threads.append(thread)
for thread in threads:
thread.join()
--wait-for-device
选项:在执行批量操作时,可以使用--wait-for-device
选项来确保在执行下一个命令之前,设备已经完全启动并准备好接收命令。这可以通过在命令字符串中使用--wait-for-device
选项来实现。commands = [
"adb --wait-for-device -s device_id install app.apk",
"adb --wait-for-device -s device_id shell input tap 100 200",
"adb --wait-for-device -s device_id pull /sdcard/file.txt ./file.txt"
]
--verbose
选项:在执行批量操作时,可以使用--verbose
选项来查看详细的调试信息。这可以帮助你识别潜在的性能问题或错误。commands = [
"adb --verbose -s device_id install app.apk",
"adb --verbose -s device_id shell input tap 100 200",
"adb --verbose -s device_id pull /sdcard/file.txt ./file.txt"
]
--no-wait
选项:在执行批量操作时,可以使用--no-wait
选项来避免在命令之间等待设备响应。这可以提高性能,但可能会导致命令执行顺序混乱。commands = [
"adb --no-wait -s device_id install app.apk",
"adb --no-wait -s device_id shell input tap 100 200",
"adb --no-wait -s device_id pull /sdcard/file.txt ./file.txt"
]
通过采取这些措施,你可以优化Python ADB命令的性能,提高执行速度并减少潜在的错误。
