这是我的代码

 extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        // Optionally, customize your config at runtime:
        //
         AirshipConfigOptions options = new AirshipConfigOptions();
         options.inProduction = false;
         options.developmentAppKey = "******************";
         options.developmentAppSecret = "*******************";

         UAirship.takeOff(this, options);

        UAirship.takeOff(this, new UAirship.OnReadyCallback() {
           @Override
          public void onAirshipReady(UAirship airship) {
              // Perform any airship configurations here

               airship.getPushManager().setPushEnabled(true);
           }
       });
    }
}

Answer 1

我也遇到了同样的问题并且弄明白了。事实证明，缺少的类已添加到API 21支持库中。我一直在使用API 19支持库并且收到此错误。

要解决此问题，您需要从API 21 Android SDK将最新 android-support-v4.jar添加到您的项目中。在您更新Android SDK之后，在Eclipse中，您可以：

1）右键单击您的项目 2）选择＆＃34; Android工具＆＃34; 3）选择＆＃34;添加支持库...＆＃34;

清洁，刷新并再试一次，你应该好好去。祝你好运！

感谢realepinski之前发表的评论，帮助我解决这个问题！

Answer 2

右键单击包含的jar。和Build path -> add to build path。确保在项目属性中properties -> java build path -> order and export并检查包含的库。

同时检查android-support-v4.jar是否在项目中引用。 Right click project -> android tools -> Add support library

在assets folder -> airshipconfig.properties

中提及您的密钥详情

使用此课程

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        // Optionally, customize your config at runtime:
        //
        // AirshipConfigOptions options = new AirshipConfigOptions();
        // options.inProduction = false;
        // options.developmentAppKey = "Your Development App Key";
        // options.developmentAppSecret "Your Development App Secret";
        //
        // UAirship.takeOff(this, options);

        UAirship.takeOff(this, new UAirship.OnReadyCallback() {
            @Override
            public void onAirshipReady(UAirship airship) {
                // Perform any airship configurations here

                airship.getPushManager().setPushEnabled(true);
            }
        });
    }
}

Answer 3

凭证可以通过两种方式添加

1）通过在Application类中设置（就像你所做的那样）

2）通过添加资产文件夹

添加所需的Urban Airship库文件。

****1. Add below code in App****  
public class App extends Application {
 @Override
    public void onCreate() {
        super.onCreate();
        UAirship.takeOff(this, new UAirship.OnReadyCallback() {
            @Override
            public void onAirshipReady(UAirship airship) {
                airship.getPushManager().setUserNotificationsEnabled(true);
            }
        });
}
}

**2. add file in below path:**
app -> assets -> airshipconfig.properties

**3. In airshipconfig.properties write below code:**
developmentAppKey=************    //  development/Staging Key                                                           developmentAppSecret=**************
productionAppKey=*********     //  Production Key          
productionAppSecret=********
inProduction=true 
developmentLogLevel=DEBUG  //LogLevel is "VERBOSE", "DEBUG", "INFO","WARN","ERROR" or "ASSERT" 
productionLogLevel=ERROR 
fcmSenderId=*******  //FCM Sender ID/Firebase project number
notificationIcon=ic_logo_small  
notificationAccentColor=#000000
notificationChannel=customChannel
