Question

我无法通过手机登录。我只在Android Studio中收到此错误：

11-01 03：28：56.427 24227-24375 / com.example.segall.caveofprogcourse E / GED：无法获得GED Log Buf，错误（0）

Android studio 2.1.3
  Ubuntu 16.04 LTS
  索尼Xperia M5
  android 6.0 api 23

我有USB调试。

修改

onCreate方法中的代码

var express = require('express');
var router = express.Router();
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var User = require('../models/user');

/* GET users listing. */
router.get('/', function(req, res, next) {
  res.send('respond with a resource');
});

router.get('/register', function(req, res, next) {
  res.render('register',{
    'title': 'Register'
  });
});

router.get('/login', function(req, res, next) {
  res.render('login',{
    'title': 'Login'
  });
});

router.post('/register', function(req, res, next){
    // Get Form Values
    var name = req.body.name;
    var email = req.body.email;
    var username = req.body.username;
    var password = req.body.password;
    var password2 = req.body.password2;

    // Check for Image Field
    if(req.files && req.files.profileimage){
        console.log('Uploading File...');

        // File Info
        var profileImageOriginalName = req.files.profileimage.originalname;
        var profileImageName = req.files.profileimage.name;
        var profileImageMime = req.files.profileimage.mimetype;
        var profileImagePath = req.files.profileimage.path;
        var profileImageExt = req.files.profileimage.extension;
        var profileImageSize = req.files.profileimage.size;
    } else {
        // Set a Default Image
        var profileImageName = 'noimage.png';
    }

    // Form Validation
    req.checkBody('name','Name field is required').notEmpty();
    req.checkBody('email','Email field is required').notEmpty();
    req.checkBody('email','Email not valid').isEmail();
    req.checkBody('username','Username field is required').notEmpty();
    req.checkBody('password','Password field is required').notEmpty();
    req.checkBody('password2','Passwords do not match').equals(req.body.password);

    // Check for Errors
    var errors = req.validationErrors();

    if(errors){
        res.render('register',{
            errors: errors,
            name: name,
            email: email,
            username: username,
            password: password,
            password2: password2
        });
    } else {
        var newUser = new User({
            name: name,
            email: email,
            username: username,
            password: password,
            profileimage: profileImageName
        });

        // Create User

        User.createUser(newUser, function(err, user){
            if(err) throw err;
            console.log(user);
        });

        User.createUser(newUser, function(err, user){
            if(err) throw err;
            console.log(user);
        });

        // Success Message
        req.flash('success', 'You are now registered and may log in');

        res.location('/');
        res.redirect('/');
    }
});

passport.serializeUser(function(user, done) {
  done(null, user.id);
});

passport.deserializeUser(function(id, done) {
  User.getUserByUsername(id, function(err, user) {
    done(err, user);
  });
});

passport.use(new LocalStrategy(
    function(username, password, done){
        User.getUserByUsername(username, function(err, user){
            if(err)throw err;
            if(!user){
                console.log('Unknown User');
                return done(null, false,{message: 'Unknown User'});
            }

            User.comparePassword(password, user.password, function(err, isMatch){
                if(err) throw err;
                if(isMatch){
                    return done(null, user);
                } else {
                    console.log('Invalid Password');
                    return done(null, false, {message: 'Invalid Password'});
                }
            });
        });
    }
));

router.post('/login', passport.authenticate('local', {failureRedirect: '/users/login', failureFlash:'Invalid username or password'}), function(req, res){
    console.log('Authentication Successful');
    req.flash('success', 'You are logged in');
    res.redirect('/');
});

router.get('/logout', function(req, res){
    req.logout();
    req.flash('success', 'You have logged out');
    res.redirect('/users/login');
});


module.exports = router;

获得以下结果：

Log.d("mylog", " LOG WORKS ");  
Log.e("mylog", "onCreate called really?"); // I added this Log

令人惊讶的是，Log.e有效。任何人都知道为什么会发生这种情况？

编辑2 我只使用onCreate

中的两个日志创建了新项目

11-01 21:51:23.561 7820-7820/com.example.segall.caveofprogcourse E/mylog: onCreate called really?  
11-01 21:51:23.619 7820-7873/com.example.segall.caveofprogcourse E/GED: Failed to get GED Log Buf, err(0)

我放了一些空行，所以很容易发现

来自app的

日志过滤器：

    Log.d("mylog","Log.d on create this  is not working");
    Log.e("mylog","Log.e surprisingly this works");

日志过滤器没有过滤器：

screen of logcat

Answer 1

尽量不要在logcat右上角使用过滤器
重新检查您的设备是否已连接并且logcat正在侦听正确的设备
选择日志类型详细
您可能需要从开发人员控制台下载配置文件并将其添加到项目中。此链接的第二步。文件名为google-services.json
检查您的lib配置，尤其是Firebase配置。

Answer 2

我有同样的问题。请更新您的Android Studio。这是一个错误

Answer 3

使用Linux（Ubuntu），您已设置系统以检测设备。您可以查看这些Google guidelines

您需要为要用于开发的每种类型的设备添加包含udev rules的{{1}}文件。

在执行此操作之前，请确认您的应用程序是＆＃34;可调试的＆＃34;在您的清单或USB configuration文件中。

build.gradle

在android { buildTypes { debug { debuggable true }文件中，将AndroidManifest.xml添加到android:debuggable="true"元素。

现在设置系统以使用 udev规则文件检测您的设备。添加udev规则文件，其中包含要用于开发的每种类型设备的USB配置。在规则文件中，每个设备制造商都由唯一的供应商ID标识，由<application>属性指定。因此，您必须了解Sonys供应商ID：ATTR{idVendor}

以root身份登录并创建此文件：054c

即

/etc/udev/rules.d/51-android.rules

使用此格式将每个供应商添加到文件中：054c是sonys供应商ID。

sudo gedit /etc/udev/rules.d/51-android.rules

如果你添加SUBSYSTEM=="usb", ATTR{idVendor}=="054c", MODE="0666", GROUP="plugdev" Android工作室将检测索尼。

现在执行：SUBSYSTEM=="usb", ATTR{idVendor}=="054c", MODE="0666", GROUP="plugdev"

关闭并启动Studio。然后运行您的项目。 Studio会检测到它

androidStudio日志不起作用
