How can I export data in real time from Android Studio to my computer
问题
我在Android Studio中使用Java创建了一个Android应用程序，需要导出一些数据进行验证。我想要将一个2维整数数组保存在我电脑或手机上的**.csv或.txt**文件中（我的手机没有SD卡槽）。
你有什么想法吗？
进一步说，我想实时将数据导出到我的电脑，并使用Python或Bash绘制这个二维数组。这可行吗？
非常感谢！

I created an android application in java in android studio and I need to export some data for validation purpose. I would like to save a 2 dimensiohs integer array in a .csv or .txt file in my computer or in my phone when I am running the application (I don't Have SD card slot in my phone).
Do you have any Idea ?
To go further, I will love to export the data in real time to my computer and to plot the 2 dimension array with python or Bash.. Is it possible ?
Thanks a lot !

你可以在控制台中运行 adb logcat 并以任何方便的方式解析实时数据：https://developer.android.com/studio/command-line/logcat
示例（Windows PowerShell）：
& $ENV:LOCALAPPDATA\Android\Sdk\platform-tools\adb.exe logcat -s MyTag
在应用程序中（Java）：
Log.d("MyTag", "My debug data");
在Python中获取实时logcat数据（Windows）：
import os, subprocess
cmd = os.getenv("LOCALAPPDATA") + r"\Android\Sdk\platform-tools\adb.exe logcat -s MyTag"
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1)
for line in iter(p.stdout.readline, b""):
print(line)
p.stdout.close()
p.wait()
提示： 你还可以通过本地Wi-Fi网络进行调试，而不需要将设备通过电缆连接到电脑上：https://stackoverflow.com/questions/2604727/how-can-i-connect-to-android-with-adb-over-tcp
英文:
You can run adb logcat in console and parse live data in any way convenient for you: https://developer.android.com/studio/command-line/logcat
Example (Windows PowerShell):
& $ENV:LOCALAPPDATA\Android\Sdk\platform-tools\adb.exe logcat -s MyTag
In app (Java):
Log.d("MyTag", "My debug data");
Getting live logcat data in Python (Windows):
import os, subprocess
cmd = os.getenv("LOCALAPPDATA") + r"\Android\Sdk\platform-tools\adb.exe logcat -s MyTag"
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1)
for line in iter(p.stdout.readline, b""):
print(line)
p.stdout.close()
p.wait()
Tip: you can also run debugging via local Wi-Fi network without connecting the device with a cable to your PC: https://stackoverflow.com/questions/2604727/how-can-i-connect-to-android-with-adb-over-tcp
