You are not getting the answer you are looking for, are you.
Two ways to do what you want:
- Right-click in the logcat messages window, choose select all. Then your save will be all logcat messages in that window (including the ones scrolled out of view).
- When focus is in logcat messages window, type control-A, this will select all messages. Then save etc. etc.
In addition to answer by Dinesh Prajapati, Use
adb -d logcat <your package name>:<log level>
where -d is for device and you may also choose -e instead for emulator log and log level is a/d/i/v/e/w etc.
Now your command goes like:
adb -d logcat com.example.example:V > logfileName_WithPath.txt
To save LogCat log to file programmatically on your device use for example this code:
String filePath = Environment.getExternalStorageDirectory() + "/logcat.txt";
Runtime.getRuntime().exec(new String[]{"logcat", "-f", filepath, "MyAppTAG:V", "*:S"});
"MyAppTAG:V" sets the priority level for all tags to Verbose (lowest priority)
"*:S" sets the priority level for all tags to "silent"

Use logcat tool with -d or -f switch and exec() method.
Saving to a file on the host computer:
exec( "adb logcat -d > logcat.log" ) // logcat is written to logcat.log file on the host.
If you are just saving to a file on the device itself, you can use:
exec( "adb logcat -f logcat.log" ) // logcat is written to logcat.log file on the device.
