Question

我一直试图建立Urban Airship几天，它真的让我很紧张。由于他们的指示不明确，我必须按照this one进行操作。但是，我目前正在收到此错误日志并试图查看是否可以找到一些帮助。如有任何建议，将不胜感激！谢谢！

我找到了类似的qnestion和答案，

- 从构建路径中删除所有Android库项目和外部jar。

在项目中创建名为“libs”的文件夹。

- 将所有外部.jars放在该文件夹中，ADT现在应将它们放在“Android Dependencies”下。

- 以正常方式重新导入所有以前的Android库项目。

但它对我不起作用。

这是Manifestfile，如果删除应用程序名称，应用程序运行正常。但我需要这样才能启用推送通知..

AndroidManifest.xml

<application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" 
        android:name="com.app.android.NotifyMeApplication"
        android:debuggable="true"
        android:allowClearUserData="true"
        android:enabled="true" >

NotifyMeApplication.java

package com.app.android;

import com.urbanairship.Logger;
import com.urbanairship.UAirship;
import com.urbanairship.push.PushManager;
import com.urbanairship.push.PushPreferences;

import android.app.Application;

public class NotifyMeApplication extends Application{

    @Override
    public void onCreate() {
        super.onCreate();
                UAirship.takeOff(this); // always needs to be called when starting an application

                // even though we call takeoff push notifications are disabled by default
                // you have to explicitly turn them on like so
                PushManager.enablePush();

                // let the push manager know about our intent receiver
                PushManager.shared().setIntentReceiver(IntentReceiver.class); 
                // name must match broadcast receiver from step 7

                // set some preferences for sounds and vibration
                PushPreferences prefs = PushManager.shared().getPreferences();
                prefs.setSoundEnabled(true);
                prefs.setVibrateEnabled(true);

                // apid is a unique identifier for a particular device
                String lPushId = prefs.getPushId();
                Logger.info("My Application onCreate - App APID: " + lPushId);

    }
}

Answer 1

如果在运行时获得NoClassDefFoundError，那么我怀疑您没有将它们包含在运行时工作。您必须选中每个.jar的复选框，如下所示：
