Adding the Android Embrace SDK #

For a sample integration, check out the Kotlin and Java apps in the Embrace demo apps repo.

Add Embrace as a dependency #

The Embrace SDK is available on Maven Central. Make the following changes in your project’s build.gradle file to add the Embrace SDK to your app.

buildscript {
  repositories {
    mavenCentral()
    google()
  }
  dependencies {
    classpath 'io.embrace:embrace-swazzler:5.5.1'
  }
}

Then, apply the Embrace swazzler plugin in your app/build.gradle file. Also, specify that the Embrace SDK uses Java 8 features with the compileOptions settings.

apply plugin: 'com.android.application'
apply plugin: 'embrace-swazzler'

repositories {
  mavenCentral()
  google()
}

android {
  ...
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
  ...
}

The Swazzler works as a support process during build time for the Embrace SDK to work properly during run time. It performs a few key functions:

• Adds the Embrace SDK dependencies to the app’s dependency list.
• Injects a build info JSON file for the SDK to parse during run time. This specifies an internal Embrace build UUID, build app ID, and the build variant.
• Runs a code transformation / injection over specified bytecode class files to add hooks that the SDK uses to capture certain data.
• Injects ProGuard rules for the SDK to work properly when a build type is set to be minified.

You’ll need to set the following permissions so the Embrace SDK can send events and monitor connectivity.

• android.permission.INTERNET
• android.permission.ACCESS_NETWORK_STATE

Add a dependency to modules or libraries you want to call Embrace from (optional) #

If you have an app that uses internal modules or libraries, you must specify the Embrace SDK dependency directly in your module’s Gradle file

implementation 'io.embrace:embrace-android-sdk:5.5.1'

You still need to apply the Swazzler plugin in the app’s Gradle file (apply plugin: 'embrace-swazzler') and verify that the Swazzler version set in your project Gradle file is the same as the version set for the SDK in the module’s Gradle file.

Add the config file #

Add a config file to configure the Embrace SDK. This file must be named embrace-config.json and should be placed in app/src/main. The config file supports many more options than those shown in the example below, but for the initial integration, only the two settings listed below are needed.

{
  "app_id": "xxxxx",
  "api_token": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

Your app ID and API token are available on the Embrace dashboard.

NDK crash capture #

If your app is written entirely in Java and Kotlin, you do not need to enable NDK crash capture to capture crashes in your code. However, we recommend enabling it since it will capture crashes that happen in Android system libraries.

If your app has native components, you can enable NDK crash capture. Simply add the ndk_enabled setting to your config file.

{
  "app_id": "xxxxx",
  "api_token": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "ndk_enabled": true
}

Unlike JVM-based crash reporters, you can only attach one set of signal handlers to capture NDK crashes. If you have another NDK crash reporter in your system, enabling NDK crash capture in the Embrace SDK will disable that NDK crash reporter if the Embrace SDK is initialized after it.

Next, you’ll be creating your first session.
