Install the dependency

1dependencies {
2    implementation 'com.amplitude:analytics-android:1.+'
3}

1<dependency>
2    <groupId>com.amplitude</groupId>
3    <artifactId>analytics-android</artifactId>
4    <version>[1.0,2.0)</version>
5</dependency>

Add permissions

After you install the library, add the following to AndroidManifest.xml

1<uses-permission android:name="android.permission.INTERNET" />

For Android 6.0 (Marshmallow) and higher, explicitly add permission to fetch the device advertising ID.

The SDK internally uses a few Java 8 language APIs through desugaring. Make sure your project either enables desugaring or requires a minimum API level of 16.

Initialize the SDK

Before you instrument,initialize the SDK using the API Key for your Amplitude project.

Amplitude recommends doing the initialization in the Main Activity, which never gets destroyed, or the Application class if you have one. After it's initialized, you can use the Android SDK anywhere in your Android application.

Note

For EU data residency, the project must be set up inside Amplitude EU. Initialize the SDK with the API key from Amplitude EU.

1import com.amplitude.android.Amplitude
2 
3val amplitude = Amplitude(
4    Configuration(
5        apiKey = AMPLITUDE_API_KEY,
6        context = applicationContext
7    )
8)

Configure the serverZone property to configure your application to use European data residency.

1import com.amplitude.android.Amplitude
2 
3val amplitude = Amplitude(
4    Configuration(
5        apiKey = AMPLITUDE_API_KEY,
6        context = applicationContext,
7        serverZone = ServerZone.EU 
8    )
9)

1import com.amplitude.android.Amplitude;
2 
3Amplitude amplitude =  new Amplitude(new Configuration(
4    apiKey = AMPLITUDE_API_KEY,
5    context = applicationContext
6));

Configure the serverZone property to configure your application to use European data residency.

1import com.amplitude.android.Amplitude;
2 
3Amplitude amplitude =  new Amplitude(new Configuration(
4    apiKey = AMPLITUDE_API_KEY,
5    context = applicationContext,
6    serverZone = ServerZone.EU 
7));

Send data

Next, send data from your app or website to Amplitude.

Events tracked are buffered locally and flushed every 30 seconds. After calling track() in your app, it may take several seconds for event data to appear in Amplitude.

1// Track a basic event
2amplitude.track("Button Clicked")
3// Track events with optional properties
4amplitude.track(
5    "Button Clicked",
6    mapOf("buttonColor" to "primary")
7)

1// Track a basic event
2amplitude.track("Button Clicked");
3// Track events with optional properties
4amplitude.track("Button Clicked", new HashMap() {{
5    put("buttonColor", "primary");
6}});

Check for success

After you begin sending data to Amplitude, use one of the debugging tools to check your instrumentation and validate your events.

2    "github.com/amplitude/analytics-go/amplitude"
3)
4 
5config := amplitude.NewConfig(AMPLITUDE_API_KEY)
6 
7client := amplitude.NewClient(config)

Send data

Next, send data from your app or website to Amplitude.

1client.Track(amplitude.Event{
2      EventType: "Button Clicked",
3      EventOptions: amplitude.EventOptions{
4      UserID:   "user-id",
5      DeviceID: "device-id",
6    },
7    EventProperties: map[string]interface{}{"source": "notification"},
8})

Check for success

After you begin sending data to Amplitude, use one of the debugging tools to check your instrumentation and validate your events.

Complete code example

Here's a complete example of how to use the SDK in your own app.

 1package main

 3import (
 4    "github.com/amplitude/analytics-go/amplitude"
 5)
 6 
 7func main() {
 8    config := amplitude.NewConfig(AMPLITUDE_API_KEY)
 9    client := amplitude.NewClient(config)
10 
11    identifyObj := amplitude.Identify{}
12    identifyObj.Set("location", "LAX")
13    client.Identify(identifyObj, amplitude.EventOptions{UserID: "user-id"})
14 
15    client.Track(amplitude.Event{
16        EventType: "Button Clicked",
17        EventOptions: amplitude.EventOptions{
18            UserID:   "user-id",
19            DeviceID: "device-id",
20        },
21        EventProperties: map[string]interface{}{"source": "notification"},
22    })
23}
