SDKの実装

Android SDKを初期化し開始する方法を説明します。

編集を提案する

始める前に

  • Android SDKをインストールする必要があります
  • Ensure that in your app build.gradle file, applicationId's value (in the defaultConfig block) matches the app's app ID in AppsFlyer.
  • AppsFlyer Devキーを取得してください。SDKを正常に初期化するために必要です
  • The codes in this document are example implementations. Make sure to change the <YOUR_DEV_KEY> and other placeholders as needed.
  • このドキュメントに含まれているステップは、特に明記されていない限り全て必須です。

Android SDKの初期化

🐣
Androidでのコンバージョンデータの取得
Open Recipe

グローバルApplicationクラス／サブクラス内でSDKを初期化することをお勧めします。これにより、全てのシナリオ（例：ディープリンク）でSDKが開始できます。

ステップ1：AppsFlyerLibのインポート
In your global Application class, import AppsFlyerLib:

import com.appsflyer.AppsFlyerLib;

import com.appsflyer.AppsFlyerLib

ステップ2：SDKの初期化
In the global Application onCreate, call init with the following arguments:

AppsFlyerLib.getInstance().init(<YOUR_DEV_KEY>, null, this);

AppsFlyerLib.getInstance().init(<YOUR_DEV_KEY>, null, this)
  1. 第一引数には、AppsFlyer Devキーを指定してください。
  2. The second argument is a Nullable AppsFlyerConversionListener. If you don't need conversion data, we recommend passing a null as the second argument. For more information, see Conversion data.
  3. 第三引数にはApplication Contextを指定します。

Android SDKの開始

In the Application's onCreate method, after calling init, call start and pass it the Application's Context as the first argument:

AppsFlyerLib.getInstance().start(this);

AppsFlyerLib.getInstance().start(this)

Deferring SDK start

オプション
You can defer the SDK initialization by calling start from an Activity class, instead of calling it in the Application class. init should still be called in the Application class.

Typical usage of deferred SDK start is when an app would like to request consent from the user to collect data in the Main Activity, and call start after getting the user's consent.

⚠️

重要なお知らせ

アプリがアクティビティから start を呼び出す場合は、アクティビティコンテキストをSDKに渡す必要があります。
アクティビティコンテキストを渡さないと、SDKがトリガーされないため、アトリビューションデータとアプリ内イベントが失われます。

Starting with a response listener

To receive confirmation that the SDK was started successfully, create an AppsFlyerRequestListener object and pass it as the third argument of start:

AppsFlyerLib.getInstance().start(getApplicationContext(), <YOUR_DEV_KEY>, new AppsFlyerRequestListener() {
  @Override
  public void onSuccess() {
    Log.d(LOG_TAG, "Launch sent successfully, got 200 response code from server");
  }
  
  @Override
  public void onError(int i, @NonNull String s) {
    Log.d(LOG_TAG, "Launch failed to be sent:\n" +
          "Error code: " + i + "\n"
          + "Error description: " + s);
  }
});

AppsFlyerLib.getInstance().start(this, <YOUR_DEV_KEY>, object : AppsFlyerRequestListener {
  override fun onSuccess() {
    Log.d(LOG_TAG, "Launch sent successfully")
    }
  
  override fun onError(errorCode: Int, errorDesc: String) {
    Log.d(LOG_TAG, "Launch failed to be sent:\n" +
          "Error code: " + errorCode + "\n"
          + "Error description: " + errorDesc)
    }
})
  • The onSuccess() callback method is invoked for every 200 response to an attribution request made by the SDK.
  • The onError(String error) callback method is invoked for any other response and returns the response as the error string.

例

次の例は、ApplicationクラスからSDK初期化を起動する方法を示しています。

import android.app.Application;
import com.appsflyer.AppsFlyerLib;
// ...
public class AFApplication extends Application {
    // ...
    @Override
    public void onCreate() {
        super.onCreate();
        // ...
        AppsFlyerLib.getInstance().init(<YOUR_DEV_KEY>, null, this);
        AppsFlyerLib.getInstance().start(this);
        // ...
    }
    // ...
}

import android.app.Application
import com.appsflyer.AppsFlyerLib
// ...
class AFApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        // ...
        AppsFlyerLib.getInstance().init(<YOUR_DEV_KEY>, null, this)
        AppsFlyerLib.getInstance().start(this)
        // ...
    }
    // ...
}

カスタマーユーザーID の設定

オプション

The Customer User ID (CUID) is a unique user identifier created by the app owner outside the SDK. It can be associated with in-app events if provided to the SDK. Once associated with the CUID, these events can be cross-referenced with user data from other devices and applications.

Set the customer User ID

Once the CUID is available, you can set it by calling  setCustomerUserId.


...
AppsFlyerLib.getInstance().init(<YOUR_DEV_KEY>, conversionListener, this);  
AppsFlyerLib.getInstance().start(this , <YOUR_DEV_KEY> );
...
// Do your magic to get the customerUserID...
...
AppsFlyerLib.getInstance().setCustomerUserId(<MY_CUID>);

The CUID can only be associated with in-app events after it was set. Since start was called before setCustomerUserID, the install event will not be associated with the CUID. If you need to associate the install event with the CUID, see the below section.

Associate the CUID with the install event

If it’s important for you to associate the install event with the CUID, you should set it before calling start.

You can set the CUID before start in two ways, depending on whether you start the SDK in the Application or the Activity class.

When starting from the application class

If you started the SDK from the Application class (see: Starting the Android SDK) and you want the CUID to be associated with the install event, put the SDK in waiting mode to prevent the install data from being sent to AppsFlyer before the CUID is provided.

To activate the waiting mode, set waitForCustomerUserId to true after init and before start.

📘Important

It's important to remember that putting the SDK in a waiting mode may block the SDK from sending the install event and consequently prevent attribution. This can occur, for example, when the user launches the application for the first time and then exits before the SDK can set the CUID. 

AppsFlyerLib.getInstance().init(<YOUR_DEV_KEY>, getConversionListener(), getApplicationContext());
AppsFlyerLib.getInstance().waitForCustomerUserId(true);
AppsFlyerLib.getInstance().start(this);

After calling start, you can add your custom code that makes the CUID available.

Once the CUID is available, the final step includes setting the CUID, releasing the SDK from the waiting mode, and sending the attribution data with the customer ID to AppsFlyer. This step is performed using the call to setCustomerIdAndLogSession.

AppsFlyerLib.getInstance().setCustomerIdAndLogSession(<CUSTOMER_ID>, this);

Other than setCustomerIdAndLogSession, do not use setCustomerUserId or any other AppsFlyer SDK functionality, as the waiting SDK will ignore it.

Note

If you wish to remove the waiting mode from the SDK initialization flow, it is not enough to delete the call to waitForCustomerUserId(true). It is also required to replace it with waitForCustomerUserID(false). Simply removing the call is insufficient because the 'waitForCustomerUserId' boolean flag is stored in the Android Shared Preferences.

サンプルコード

public class AFApplication extends Application {
  @Override
  public void onCreate() {
    super.onCreate();
    AppsFlyerConversionListener conversionDataListener = 
    new AppsFlyerConversionListener() {
      ...
    };
    AppsFlyerLib.getInstance().init(<YOUR_DEV_KEY>, getConversionListener(), getApplicationContext());
    AppsFlyerLib.getInstance().waitForCustomerUserId(true);
    AppsFlyerLib.getInstance().start(this);
    // Do your magic to get the customerUserID
    // any AppsFlyer SDK code invoked here will be discarded
    // ...
    // Once the customerUserID is available, call setCustomerIdAndLogSession(). 
    // setCustomerIdAndLogSession() sets the CUID, releases the waiting mode,
    // and sends the attribution data with the customer ID to AppsFlyer.
    AppsFlyerLib.getInstance().setCustomerIdAndLogSession(<CUSTOMER_ID>, this);
  }
}

When starting from the Activity class

If you started the SDK from an Activity (see: Deferring SDK start) class and you want the CUID to be associated with the install event, set the CUID beforestart.

デバッグモードの有効化

オプション
You can enable debug logs by calling setDebugLog:

AppsFlyerLib.getInstance().setDebugLog(true);

AppsFlyerLib.getInstance().setDebugLog(true)

📘

注意

To see full debug logs, make sure to call setDebugLog before invoking other SDK methods.

例を参照してください。

警告

機密情報の漏洩を防ぐため、アプリをリリースする前にデバッグログが無効になっていることを確認してください。
