We also recommend that a 185 | file or class name and description of purpose be included on the 186 | same "printed page" as the copyright notice for easier 187 | identification within third-party archives. 188 | 189 | Copyright 2015 Erlang Solutions Ltd. 190 | 191 | Licensed under the Apache License, Version 2.0 (the "License"); 192 | you may not use this file except in compliance with the License. 193 | You may obtain a copy of the License at 194 | 195 | http://www.apache.org/licenses/LICENSE-2.0 196 | 197 | Unless required by applicable law or agreed to in writing, software 198 | distributed under the License is distributed on an "AS IS" BASIS, 199 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 200 | See the License for the specific language governing permissions and 201 | limitations under the License. 202 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | Galgo 2 | ===== 3 | [![Android Arsenal](https://img.shields.io/badge/Android%20Arsenal-Galgo-brightgreen.svg?style=flat)](https://android-arsenal.com/details/1/1151) 4 | 5 | A tiny Android library for those moments when you want your logs to be displayed on screen. 6 | 7 | ### Abstract 8 | 9 | Sometimes we want/need to know what's going on behind the scenes but our app is not always connected to our computer to let us check the logs. Galgo will let you display your log messages as an overlay on top of your UI. 10 | 11 | Extremely useful for testers who want to have more insight into what's going on behind the scenes in our apps when it misbehaves. 12 | 13 | You can also define some basic settings such as background color, text color, text size and number of lines to display on screen so it better fits your needs. 14 | 15 | ### How to download and Install 16 | Add the following to your `build.gradle` file: 17 | 18 | ```groovy 19 | repositories { 20 | maven { 21 | url "https://jitpack.io" 22 | } 23 | } 24 | 25 | dependencies { 26 | // ... 27 | compile 'com.github.inaka:galgo:v1.0.2' 28 | // ... 29 | } 30 | ``` 31 | 32 | Another option is to simply clone this repo and import it into Android Studio as a module. 33 | 34 | ### Code Example 35 | ```java 36 | public class ExampleActivity extends Activity { 37 | 38 | @Override 39 | protected void onCreate(Bundle savedInstanceState) { 40 | super.onCreate(savedInstanceState); 41 | setContentView(R.layout.activity_example); 42 | 43 | // add some customization to the log messages 44 | GalgoOptions options = new GalgoOptions.Builder() 45 | .numberOfLines(15) 46 | .backgroundColor(Color.parseColor("#D9d6d6d6")) 47 | .textColor(Color.BLACK) 48 | .textSize(15) 49 | .build(); 50 | Galgo.enable(this, options); 51 | 52 | Galgo.log("I am a log message"); 53 | } 54 | 55 | public void onDestroy() { 56 | super.onDestroy(); 57 | 58 | // always call disable to avoid memory leaks 59 | Galgo.disable(this); 60 | } 61 | } 62 | ``` 63 | 64 | ### Example 65 | Here's an example of the log messages being displayed on top of our Activity: 66 | 67 | 68 | 69 | ### Contact Us 70 | If you find any **bugs** or have a **problem** while using this library, please [open an issue](https://github.com/inaka/galgo/issues/new) in this repo (or a pull request :)). 71 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.library' 2 | buildscript { 3 | repositories { 4 | jcenter() 5 | } 6 | dependencies { 7 | classpath 'com.android.tools.build:gradle:2.2.0' 8 | classpath 'com.github.dcendents:android-maven-plugin:1.2' 9 | } 10 | } 11 | 12 | 13 | android { 14 | compileSdkVersion 26 15 | buildToolsVersion '26.0.1' 16 | 17 | defaultConfig { 18 | minSdkVersion 9 19 | targetSdkVersion 26 20 | versionCode 2 21 | versionName "1.0.3" 22 | } 23 | buildTypes { 24 | release { 25 | minifyEnabled false 26 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 27 | } 28 | } 29 | } 30 | 31 | dependencies { 32 | compile fileTree(dir: 'libs', include: ['*.jar']) 33 | } 34 | -------------------------------------------------------------------------------- /downloads/galgo-release-1.0.2.aar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/inaka/galgo/24100d981bf2f1bc907eabbaad3f7dfe35ffa7f4/downloads/galgo-release-1.0.2.aar -------------------------------------------------------------------------------- /downloads/galgo-release-1.0.aar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/inaka/galgo/24100d981bf2f1bc907eabbaad3f7dfe35ffa7f4/downloads/galgo-release-1.0.aar -------------------------------------------------------------------------------- /galgo.iml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 8 | 9 | 10 | 11 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/inaka/galgo/24100d981bf2f1bc907eabbaad3f7dfe35ffa7f4/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | #Thu Aug 03 11:59:08 BST 2017 2 | distributionBase=GRADLE_USER_HOME 3 | distributionPath=wrapper/dists 4 | zipStoreBase=GRADLE_USER_HOME 5 | zipStorePath=wrapper/dists 6 | distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip 7 | -------------------------------------------------------------------------------- /proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # By default, the flags in this file are appended to flags specified 3 | # in /Users/quique/android-sdk/tools/proguard/proguard-android.txt 4 | # You can edit the include path and order by changing the proguardFiles 5 | # directive in build.gradle. 6 | # 7 | # For more details, see 8 | # http://developer.android.com/guide/developing/tools/proguard.html 9 | 10 | # Add any project specific keep options here: 11 | 12 | # If your project uses WebView with JS, uncomment the following 13 | # and specify the fully qualified class name to the JavaScript interface 14 | # class: 15 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 16 | # public *;
