Summary

This is the Android SDK of adjust™. You can read more about adjust™ at adjust.com.

Basic Installation

These are the minimal steps required to integrate the adjust SDK into your Android project. We are going to assume that you use Eclipse for your Android development.

1. Get the SDK

Download the latest version from our releases page. Extract the archive in a folder of your choice.

2. Create the Adjust project

In the Eclipse menu select File → New → Project....

From the Wizard expand the Android group and select Android Project from Existing Code and click Next.

On the top of the next screen click the Browse... button and locate the folder you extracted in step 1. Select the Adjust subfolder and click Open. In the Projects: group make sure the Adjust project is selected. Also tick the option Copy projects into workspace and click Finish.

3. Add the adjust library to your project

In the Package Explorer right click on your Android project and select Properties.

In the left pane select Android. In the bottom right group Library click the Add... button. From the list select the Adjust library project and click OK. Save your changed project properties by clicking OK again.

4. Add permissions

Google Play Store

Since the 1st of August of 2014, apps in the Google Play Store must use the Google Advertising ID to uniquely identify the devices. To allow the adjust SDK to use the Google Advertising ID, you must integrate the Google Play Services.

In the Package Explorer open the AndroidManifest.xml of your Android project. Add the uses-permission tag for INTERNET if it's not present already.

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

If you are using Proguard, add these lines to your Proguard file:

-keep class com.adjust.sdk.** { *; }
-keep class com.google.android.gms.common.** { *; }
-keep class com.google.android.gms.ads.identifier.** { *; }
```

#### Other Stores

In the Package Explorer open the `AndroidManifest.xml` of your Android project.
Add the `uses-permission` tags for `INTERNET` and `ACCESS_WIFI_STATE` if they
aren't present already.

```xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
```

![][permissions]

If you are using Proguard, add these lines to your Proguard file:

-keep class com.adjust.sdk.** { *; }


### 5. Add Adjust settings

Still in the `AndroidManifest.xml`, add the following `meta-data` tags inside
the `application` tag.

```xml
<meta-data android:name="AdjustAppToken"    android:value="{YourAppToken}" />
<meta-data android:name="AdjustLogLevel"    android:value="info" />
<meta-data android:name="AdjustEnvironment" android:value="sandbox" /> <!-- TODO: change to 'production' -->

Replace {YourAppToken} with your App Token. You can find in your dashboard.

You can increase or decrease the amount of logs you see by changing the value of AdjustLogLevel to one of the following:

  • verbose - enable all logging
  • debug - enable more logging
  • info - the default
  • warn - disable info logging
  • error - disable warnings as well
  • assert - disable errors as well

Depending on whether or not you build your app for testing or for production you must adjust the AdjustEnvironment setting:

  • sandbox - for testing
  • production - before publishing

Important: This value should be set to sandbox if and only if you or someone else is testing your app. Make sure to set the environment to production just before you publish the app. Set it back to sandbox when you start testing it again.

We use this environment to distinguish between real traffic and artificial traffic from test devices. It is very important that you keep this value meaningful at all times! Especially if you are tracking revenue.

6. Add broadcast receiver

Still in your AndroidManifest.xml, add the following receiver tag inside the application tag.

<receiver
    android:name="com.adjust.sdk.ReferrerReceiver"
    android:exported="true" >
    <intent-filter>
        <action android:name="com.android.vending.INSTALL_REFERRER" />
    </intent-filter>
</receiver>

We use this broadcast receiver to retrieve the install referrer to improve conversion tracking.

If you are already using a different broadcast receiver for the INSTALL_REFERRER intent, follow these instructions to add the Adjust receiver.

7. Integrate adjust into your app

To provide proper session tracking it is required to call certain Adjust methods every time any Activity resumes or pauses. Otherwise the SDK might miss a session start or session end. In order to do so you should follow these steps for each Activity of your app:

  • Open the source file of your Activity.
  • Add the import statement at the top of the file.
  • In your Activity's onResume method call Adjust.onResume. Create the method if needed.
  • In your Activity's onPause method call Adjust.onPause. Create the method if needed.

After these steps your activity should look like this:

import com.adjust.sdk.Adjust;
// ...
public class YourActivity extends Activity {
    protected void onResume() {
        super.onResume();
        Adjust.onResume(this);
    }
    protected void onPause() {
        super.onPause();
        Adjust.onPause();
    }
    // ...
}

Repeat these steps for every Activity of your app. Don't forget these steps when you create new Activities in the future. Depending on your coding style you might want to implement this in a common superclass of all your Activities.

8. Build your app

Build and run your Android app. In your LogCat viewer you can set the filter tag:Adjust to hide all other logs. After your app has launched you should see the following Adjust log: Tracked session start

Additional Features

Once you have integrated the adjust SDK into your project, you can take advantage of the following features.

9. Add tracking of custom events.

You can tell adjust about every event you want. Suppose you want to track every tap on a button. You would have to create a new Event Token in your dashboard. Let's say that Event Token is abc123. In your button's onClick method you could then add the following line to track the click:

Adjust.trackEvent("abc123");

You can also register a callback URL for that event in your dashboard and we will send a GET request to that URL whenever the event gets tracked. In that case you can also put some key-value-pairs in a dictionary and pass it to the trackEvent method. We will then append these named parameters to your callback URL.

For example, suppose you have registered the URL http://www.adjust.com/callback for your event with Event Token abc123 and execute the following lines:

Map<String, String> parameters = new HashMap<String, String>();
parameters.put("key", "value");
parameters.put("foo", "bar");
Adjust.trackEvent("abc123", parameters);

In that case we would track the event and send a request to:

http://www.adjust.com/callback?key=value&foo=bar

It should be mentioned that we support a variety of placeholders like {android_id} that can be used as parameter values. In the resulting callback this placeholder would be replaced with the AndroidID of the current device. Also note that we don't store any of your custom parameters, but only append them to your callbacks. If you haven't registered a callback for an event, these parameters won't even be read.

10. Add tracking of revenue

If your users can generate revenue by clicking on advertisements or making purchases you can track those revenues. If, for example, a click is worth one cent, you could make the following call to track that revenue:

Adjust.trackRevenue(1.0);

The parameter is supposed to be in cents and will get rounded to one decimal point. If you want to differentiate between different kinds of revenue you can get different Event Tokens for each kind. Again, you need to create those Event Tokens in your dashboard. In that case you would make a call like this:

Adjust.trackRevenue(1.0, "abc123");

Again, you can register a callback and provide a dictionary of named parameters, just like it worked with normal events.

Map<String, String> parameters = new HashMap<String, String>();
parameters.put("key", "value");
parameters.put("foo", "bar");
Adjust.trackRevenue(1.0, "abc123", parameters);

11. Set listener for delegate notifications

Every time your app tries to track a session, an event or some revenue, you can be notified about the success of that operation and receive additional information about the current install.

Please make sure to consider applicable attribution data policies.

The simplest way is to create a single anonymous listener for these notifications.

  • Open the source file of your main activity, find its onResume method and add the following code below your Adjust.onResume call:

    Adjust.onResume(this);
    
    Adjust.setOnFinishedListener(new OnFinishedListener() {
        public void onFinishedTracking(ResponseData responseData) {
        }
    });
  • Alternatively, you could implement the OnFinishedListener interface in your activity and pass the activity:

    Adjust.setOnFinishedListener(this);

This OnFinishedListener will only be set if this activity has been active before. You can set it in all activities to make sure that it is always set, regardless of what activities have been active. In this case it makes sense to implement the OnFinishedListener interface in one class and set the listener to the same object in every onResume method.

The listener method onFinishedTracking will get called every time any activity was tracked or failed to track. Within this listener function you have access to the responseData parameter. Here is a quick summary of its interface:

  • ActivityKind getActivityKind() indicates what kind of activity was tracked. Returns one of these values:

    ActivityKind.SESSION
    ActivityKind.EVENT
    ActivityKind.REVENUE
    ActivityKind.REATTRIBUTION
  • String getActivityKindString() human readable version of the activity kind. Possible values:

    session
    event
    revenue
    reattribution
    
  • boolean wasSuccess() indicates whether or not the tracking attempt was successful.

  • boolean willRetry() is true when the request failed, but will be retried.

  • String getError() an error message when the activity failed to track or the response could not be parsed. Is null otherwise.

  • String getTrackerToken() the tracker token of the current install. Is null if request failed or response could not be parsed.

  • String getTrackerName() the tracker name of the current install. Is null if request failed or response could not be parsed.

  • String getNetwork() the network grouping level of the current install. Is null if request failed, unavailable, or response could not be parsed.

  • String getCampaign() the campaign grouping level of the current install. Is null if request failed, unavailable or response could not be parsed.

  • String getAdgroup() the ad group grouping level of the current install. Is null if request failed, unavailable or response could not be parsed.

  • String getCreative() the creative grouping level of the current install. Is null if request failed, unavailable or response could not be parsed.

12. Enable event buffering

If your app makes heavy use of event tracking, you might want to delay some HTTP requests in order to send them in one batch every minute. You can enable event buffering by adding the following line to your Adjust settings in your AndroidManifest.xml file.

<meta-data android:name="AdjustEventBuffering" android:value="true" />

13. Disable tracking

You can disable the adjust SDK from tracking by invoking the method setEnabled with the enabled parameter as false. This setting is remembered between sessions, but it can only be activated after the first session.

Adjust.setEnabled(false);

You can verify if the adjust SDK is currently active with the method isEnabled. It is always possible to activate the adjust SDK by invoking setEnable with the enabled parameter as true.

14. Handle deep linking

You can also set up the adjust SDK to read deep links that come to your app. We will only read the data that is injected by adjust tracker URLs. This is essential if you are planning to run retargeting or re-engagement campaigns with deep links.

For each activity that accepts deep links, find the onCreate method and add the folowing call to adjust:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = getIntent();
    Uri data = intent.getData();
    Adjust.appWillOpenUrl(data);
    //...
}
