A logger which writes to android output.
## Example
```
#[macro_use] extern crate log;
extern crate android_logger;
use log::LevelFilter;
use android_logger::Config;
/// Android code may not have obvious "main", this is just an example.
fn main() {
android_logger::init_once(
Config::default().with_max_level(LevelFilter::Trace),
);
debug!("this is a debug {}", "message");
error!("this is printed by default");
}
```
## Example with module path filter
It is possible to limit log messages to output from a specific crate,
and override the logcat tag name (by default, the crate name is used):
```
#[macro_use] extern crate log;
extern crate android_logger;
use log::LevelFilter;
use android_logger::{Config,FilterBuilder};
fn main() {
android_logger::init_once(
Config::default()
.with_max_level(LevelFilter::Trace)
.with_tag("mytag")
.with_filter(FilterBuilder::new().parse("debug,hello::crate=trace").build()),
);
// ..
}
```
## Example with a custom log formatter
```
use android_logger::Config;
android_logger::init_once(
Config::default()
.with_max_level(log::LevelFilter::Trace)
.format(|f, record| write!(f, "my_app: {}", record.args()))
)
