Just playing around with Log.isLoggable(tag, level) method.
Log.d(LOGTAG, "--- debug log");
Log.i(LOGTAG, "--- info log");
if (Log.isLoggable(LOGTAG, Log.INFO)) Log.i(LOGTAG, "---
isLoggable info log");
if (Log.isLoggable(LOGTAG, Log.DEBUG)) Log.d(LOGTAG, "---
isLoggable debug log");
These all send output to the log except the last.
Following the instructions in the API for Log.isLoggable I used adb to
set the value of LOGTAG to DEBUG as follows -
# setprop com.foo.bar DEBUG
where "com.foo.bar" is the value of LOGTAG. But the 4th Log still does
not print. I tried stopping and restarting the emulator and removing
and reinstalling the app and setting the property before the app
started. No luck so far.
I was assuming the mechanism would allow me to turn up the logging
verbosity on a running app, but so far I don't get isLoggable to do
anything at all. Any suggestions?
Related questions:
- What API call will get the values that you see with "adb shell
getprop"?
- isLoggable suggests creating a /data/local.prop file. Is the idea
to copy that file onto the device or is there another way?
