The Application interface provides simple logging facilities that give granular control over which messages should be logged.
A message can be a normal info message, an error message with an optional exception or a debug message:
Gdx.app.log("MyTag", "my informative message");
Gdx.app.error("MyTag", "my error message", exception);
Gdx.app.debug("MyTag", "my debug message");
On desktop, the messages are logged to the console; on Android to LogCat; and on GWT they are logged either to the browser console or to a TextArea provided in the GwtApplicationConfiguration.
Logging can be limited to a specific logging level:
Gdx.app.setLogLevel(logLevel);
where logLevel can be one of the following values:
Application.LOG_DEBUG: logs all messages.Application.LOG_INFO: logs error and normal messages.Application.LOG_ERROR: logs only error messages.Application.LOG_NONE: mutes all logging.
