Usage

From source file:Main.java

private static void print(StackTraceElement element, Object message, Throwable error) {
    String className = element.getClassName();
    className = className.substring(className.lastIndexOf(".") + 1);
    String tag = className + '.' + element.getMethodName() + '(' + element.getFileName() + ':'
            + element.getLineNumber() + ')';
    String text = toString(message);

    if (error != null) {
        Log.e("[KakaCache]", tag + "\n\t" + text, error);
    } else {//from  w w  w .j a  v  a  2 s.co  m
        Log.e("[KakaCache]", tag + "\n\t" + text);
