Bienvenido al Log de #APP_NAME#!

Cómo utilizar este Log:

10 |

Para ver el log que ha generado tu dispositivo, sólo tienes que concatenar a tu actual URL el path /log, con ello ya tendrás acceso para ver lo que ocurre en tu dispositivo.

11 |

Pero quizá ver toda esta información al mismo tiempo puede ser algo engorroso, así que puedes ir un poco más allá filtrando por líneas:

Ejemplos de filtrado:

You will never need to connect your cable again to debug or view logs. 3 | 4 | ## Why? 5 | * Does anyone on your team, who is not Android developer, need to view logs? Maybe back-end developers? They test webservices in Postman, SoapUI, Advanced REST Client... but they do not obtain the same results as with the APP? Why not test the APP directly? You only have to write logs to see them in the browser. 6 | * Because you can integrate this ligthweight library and just run it into debug builds. 7 | * Because you can unplug the debug cable and turn off adb commands. 8 | * Because Android Studio Logcat window shows raw data. 9 | 10 | ## How it works? 11 | When you add this library to your Android application, it enables a web server to allow access to getting Android Logcat info in real-time. You only need run some browser and request a query to IP direction of your device (like http://192.168.0.128:8080). Note that is necesary share the same network. Once you get the fist connection to */log* path, automatically the content be reload frequently providing the latest changes. Remember that you can also filter the content using the search engine. 12 | 13 | ## How can you setup it? 14 | You only need to follow these 3 steps: 15 | 1) Add [this .AAR library](https://github.com/mipegir/RemoteLogcatLibrary/raw/master/downloads/remotelogcat_v1.1.aar) to your **app/libs** folder. 16 | 2) Add these lines to the **app/build.gradle** file. 17 | ```java 18 | repositories { 19 | ... 20 | flatDir { 21 | dirs 'libs' 22 | } 23 | } 24 | ... 25 | dependencies { 26 | compile fileTree(include: ['*.jar'], dir: 'libs') 27 | ... 28 | //RemoteLogcat 29 | compile(name: "remotelogcat_v1.1", ext: 'aar') 30 | } 31 | ``` 32 | 3) Code this lines in your custom *Application class or Activity*. 33 | ```java 34 | @Override 35 | public void onCreate() { 36 | super.onCreate(); 37 | 38 | if (BuildConfig.DEBUG) { //avoid execution on release, it is only for testing purpoise 39 | RemoteLogcatServer logcatServer 40 | = new RemoteLogcatServer( 41 | 8080, //port to open connection 42 | 5000, //page reload rate (ms) 43 | getApplicationContext() 44 | ); 45 | logcatServer.startServer(); 46 | } 47 | } 48 | ``` 49 | 50 | When you runs your APP, a default Android notification shows IP Address of your mobile phone to start conections. If you touch it, your browser opens welcome page to show tracked info from your Android Logcat. 51 | 52 | I hope you enjoy it!
