}
}Add the dependency
compile 'com.github.tianzhijiexian:logger:Latest release(<-click)'

Usage
With Timber
public class DefaultLogTree extends Timber.DebugTree {
private LogDelegate mDelegate;
public DefaultLogTree(LogSettings settings) {
this(settings, new DefaultLogFormatter()); // or new PrettyFormatter()
}
DefaultLogTree(LogSettings settings, AbsLogFormatter formatter) {
mDelegate = new LogDelegate(settings, formatter,
(priority, tag, message, throwable) -> Log.println(priority, tag, message));
}
@Override
protected boolean isLoggable(String tag, int priority) {
return mDelegate.isLoggable(priority, tag);
}
@Override
protected String createStackElementTag(@NonNull StackTraceElement element) {
return mDelegate.getAutoTag(element);
}
@Override
protected void log(int priority, String tag, @NonNull String message, Throwable t) {
mDelegate.printLog(priority, tag, message, t);
}
}Timber.plant(new DefaultLogTree(settings));Timber.d("debug");
Timber.e("error");
Timber.w("warning");
Timber.v("verbose");
Timber.i("information");
Timber.wtf("wtf!!!!");
Timber.tag("Custom Tag").w("logger with custom tag"); // tag
Timber.i(JsonXmlParser.json(json)); // json
Timber.i(JsonXmlParser.xml(xmlStr)); // xml
// object
Timber.d(ObjParser.obj(new User("jack", "f")));
// list
Timber.d(ObjParser.obj(Arrays.asList("kale", "jack", "tony")));
// array
Timber.d(ObjParser.obj(new String[]{"Android", "ios", "wp"}));With Your LogUtil
public final class LogUtils {
private static LogDelegate sDelegate;
public static void init(LogSettings settings) {
sDelegate = new LogDelegate(settings, new DefaultLogFormatter(),
(priority, tag, message, throwable) -> Log.println(priority, tag, message));
}
public static boolean isLoggable(int priority, String tag) {
return sDelegate.isLoggable(priority, tag);
}
public static void d(String tag, String message) {
if (isLoggable(Log.DEBUG, tag)) {
print(Log.DEBUG, tag, message);
}
}
public static void d(String message) {
String tag = sDelegate.getAutoTag(null);
d(tag, message);
}
public static void e(String tag, String message) {
if (isLoggable(Log.ERROR, tag)) {
print(Log.ERROR, tag, message);
}
}
public static void openLog(boolean b) {
if (b) {
sDelegate.getSettings().changeLogLev(Log.VERBOSE);
} else {
sDelegate.getSettings().closeLog();
}
}
private static void print(int priority, String tag, String message) {
sDelegate.printLog(priority, tag, message, null);
}
}LogUtils.init(settings);
LogUtils.d("kale-tag", "my message");
LogUtils.d("my message");
LogUtils.e("kale-tag", "my error message");
Settings
This should be called only once. Best place would be in application class, all of them are optional.
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
LogSettings settings = new LogSettings.Builder()
.showMethodLink(true)
.showThreadInfo(true)
.tagPrefix("kale")
.globalTag("GLOBAL-TAG")
.methodOffset(1)
.logPriority(BuildConfig.DEBUG ? Log.VERBOSE : Log.ASSERT)
.build();
