public static boolean isLoggable (String tag, int level)
Since: API Level 1
Checks to see whether or not a log for the specified tag is loggable at the specified level. The default level of any tag is set to INFO. This means that any level above and including INFO will be logged. Before you make any calls to a logging method you should check to see if your tag should be logged. You can change the default level by setting a system property: 'setprop log.tag.<YOUR_LOG_TAG> <LEVEL>' Where level is either VERBOSE, DEBUG, INFO, WARN, ERROR, ASSERT, or SUPPRESS. SUPPRESS will turn off all logging for your tag. You can also create a local.prop file that with the following in it: 'log.tag.<YOUR_LOG_TAG>=<LEVEL>' and place that in /data/local.prop.
Parameters
| tag | The tag to check. |
|---|---|
| level | The level to check. |
Returns
- Whether or not that this is allowed to be logged.
Throws
| IllegalArgumentException | is thrown if the tag.length() > 23. |
