简介：loglibrary 是对Android Log进行了一层封装，主要实现了打印msg，且可以在Logcat页点击类名，跳转到相应的位置。

Log封装

import android.util.Log;

public class LogUtils {
    private static String className;
    private static String methodName;
    private static int lineNumber;

    public static boolean isDebuggable() {
        return BuildConfig.DEBUG;
    }

    private static String createLog(String log) {
        StringBuffer buffer = new StringBuffer();
        buffer.append("****************");
        buffer.append(methodName);
        buffer.append("(").append(className).append(":").append(lineNumber).append(")****************");
        buffer.append(log);
        return buffer.toString();
    }

    /**
     * 获取文件名、方法名、所在行数

     * @param sElements
     */
    private static void getMethodNames(StackTraceElement[] sElements) {
        className = sElements[1].getFileName();
        methodName = sElements[1].getMethodName();
        lineNumber = sElements[1].getLineNumber();
    }

    public static void e(String message) {
        if (!isDebuggable())
            return;
        getMethodNames(new Throwable().getStackTrace());
        Log.e(className, createLog(message));
    }

    public static void i(String message) {
        if (!isDebuggable())
            return;
        getMethodNames(new Throwable().getStackTrace());
        Log.i(className, createLog(message));
    }

    public static void d(String message) {
        if (!isDebuggable())
            return;
        getMethodNames(new Throwable().getStackTrace());
        Log.d(className, createLog(message));
    }

    public static void v(String message) {
        if (!isDebuggable())
            return;
        getMethodNames(new Throwable().getStackTrace());
        Log.v(className, createLog(message));
    }

    public static void w(String message) {
        if (!isDebuggable())
            return;
        getMethodNames(new Throwable().getStackTrace());
        Log.w(className, createLog(message));
    }


}

使用了Android studio生成的BuildConfig.DEBUG来控制日志是否打印，当打release包的时候，关闭日志打印。

android {
        buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
        debug {
            debuggable true
        }
    }
}
