Integrate Fabric with Libgdx

Question

I am trying to integrate the Fabric SDK with my libgdx application for Android.

The Android Studio plugin provided by fabric.io does not work with my Gradle build files (generated by the Libgdx tool). The plugin just does not touch them.

So I tried to edit them manually. This is my build.gradle file:

buildscript {
    repositories {
        mavenCentral()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.+'
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

allprojects {
    apply plugin: "eclipse"
    apply plugin: "idea"

    version = '1.0'
    ext {
        appName = 'App'
        gdxVersion = '1.5.4'
        roboVMVersion = '1.0.0-beta-04'
        box2DLightsVersion = '1.3'
        ashleyVersion = '1.3.1'
        aiVersion = '1.5.0'
    }

    repositories {
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        maven { url "https://oss.sonatype.org/content/repositories/releases/" }
    }
}

project(":desktop") {
    apply plugin: "java"

    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-lwjgl:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-desktop"
        compile "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-desktop"
    }
}

project(":android") {
    apply plugin: "android"
    apply plugin: 'io.fabric'

    configurations { natives }

    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-android:$gdxVersion"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi-v7a"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-x86"
        compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-armeabi"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-armeabi-v7a"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-x86"
    }

    repositories {
        mavenCentral()
        maven { url 'https://maven.fabric.io/public' }
    }
}

project(":core") {
    apply plugin: "java"

    dependencies {
        compile "com.badlogicgames.gdx:gdx:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
    }
}

tasks.eclipse.doLast {
    delete ".project"
}

I have not touched the android/build.gradle file.

android {
    buildToolsVersion "22.0.1"
    compileSdkVersion 22
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'

            res.srcDirs = ['res']
            assets.srcDirs = ['assets']

        if (outputDir != null) {
            copy {
                from zipTree(jar)
                into outputDir
                include "*.so"
            }
        }
    }
}

task run(type: Exec) {
    def path
    def localProperties = project.file("../local.properties")
    if (localProperties.exists()) {
        Properties properties = new Properties()
        localProperties.withInputStream { instr ->
            properties.load(instr)
        }
        def sdkDir = properties.getProperty('sdk.dir')
        if (sdkDir) {
            path = sdkDir
        } else {
            path = "$System.env.ANDROID_HOME"
        }
    } else {
        path = "$System.env.ANDROID_HOME"
    }

    def adb = path + "/platform-tools/adb"
    commandLine "$adb", 'shell', 'am', 'start', '-n', 'net.snuzzle.android/net.snuzzle.android.AndroidLauncher'
}

                            option(name: "UPDATE_PROPERTY_FILES", value: "true")
                        }
                    }
                }
            }
        }
    }
}
dependencies {
    compile 'com.android.support:support-v4:22.1.1'
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.melnykov:floatingactionbutton:1.2.0'
}

The SDK is just not in the classpath.

I'm using this way to add Fabric (Crashlytics) to my LibGDX projects.

This is my build.gradle.

buildscript {
    repositories {
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
        ///...
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

///...

project(":android") {
    apply plugin: 'com.android.application'
    apply plugin: 'io.fabric'

    repositories {
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }

///....
  dependencies {
   //...
   compile('com.crashlytics.sdk.android:crashlytics:2.2.2@aar') {
        transitive = true;
    }
//...

I think the only difference with your gradle config is adding crashlytics dependency.

Now add android.permission.INTERNET permission in your manifest, also in onCreate method of AndroidLauncher add this line

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Fabric.with(this, new Crashlytics());
///...

Don't forget to create fabric.properties file in your android module and add these lines to it:

apiSecret= YOUR_API_SECRET_FROM_PANEL
apiKey=YOUR_API_KEY_FROM_PANEL

Now click on (fabric plugin for android studio) and sign in then click on install crashlytics (or other services) , after some next buttons you will see a dialog which tells you to run your application for activating fabric.

Now you will see your game in fabric panel.
