Set permission about logcatreader HOT 5 OPEN

Hmm... it should work. Are you sure you didn't misspell anything?
adb shell pm grant com.dp.logcatapp android.permission.READ_LOGS

Also, what version of Android?

from logcatreader.

I presume the error was misreading the command. It appears as 3 lines when displayed by the app, given my screen resolution and font size. It is really all on a single line.
Here a slight alternative:
Open a DOS window by pressing the "Windows" key then typing "cmd" then enter.
Use "cd /folder_to_adb.exe"
Type "adb devices"
If your phone is recognized;
Type "adb shell" and enter

You are now in an interactive linux style shell executing in your phone.
Type: "pm grant com.dp.logcatapp android.permission.READ_LOGS"

pm is a command which will read 3 parameters
grant is the first parameter
com.dp.logcatapp is the second parameter. It is the internal name that identify the app
Finally, the third parameter is the name of the permission.

This works without needing root. The app, after restart, immediately print all those log lines.
Thanks for sharing the source code.

Do I have to restart the app or my device?
Is there a possibility to show in Logcat Reader if READ_LOGS is already granted?

I sent the command with adb and got no error, so I guess it worked. But Logcat doesn't show logs from other apps.

You need to kill the app and restart it too :
