抱歉，如果这是一个重复的问题，它看起来很基本，但我找不到任何答案。
我尝试在 Kindle Fire 平板电脑中运行 Amazon 的 SNS KindleMobilePushApp 演示应用程序，但出现以下错误：

这发生在示例项目的此类的默认构造函数中：
package com.amazonaws.kindletest;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;
import android.app.Notification;
import android.app.Notification.Builder;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import com.amazon.device.messaging.ADMConstants;
import com.amazon.device.messaging.ADMMessageHandlerBase;
import com.amazon.device.messaging.ADMMessageReceiver;
public class ADMMessageHandler extends ADMMessageHandlerBase {
private static String savedMessage = null;
private static int numberOfMissedMessages = 0;
public static boolean inBackground = true;
public ADMMessageHandler(){
super(ADMMessageHandler.class.getName()); //ERROR!
}
...
}
它源自亚马逊库中的此类：
package com.amazon.device.messaging.ADMMessageHandlerBase
import android.app.IntentService;
import android.content.Intent;
public abstract class ADMMessageHandlerBase extends IntentService {
public ADMMessageHandlerBase(String var1) {
super((String)null);
throw new RuntimeException("Stub!");
}
protected final void onHandleIntent(Intent var1) {
throw new RuntimeException("Stub!");
}
protected abstract void onMessage(Intent var1);
protected abstract void onRegistrationError(String var1);
protected abstract void onRegistered(String var1);
protected abstract void onUnregistered(String var1);
}
我知道亚马逊的类是一个存根，旨在被实际实现替换，但这是如何完成的？这是我的 build.gradle：
buildscript {
repositories {
mavenCentral() // or jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1+'
}
}
apply plugin: 'com.android.application'
android {
compileSdkVersion 18
buildToolsVersion "23.0.1"
dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}
defaultConfig {
applicationId "com.amazonaws.kindletest"
minSdkVersion 11
targetSdkVersion 18
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
并体现：
