对不起，如果这是一个重复问题，它看起来很基本，但我找不到任何答案。 我试图运行在的Kindle Fire平板电脑亚马逊的SNS KindleMobilePushApp演示应用程序，但我得到了以下错误：java.lang.RuntimeException：无法实例化Android存根

这发生在这个类样本项目的默认构造函数：
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!
}
...
}
这是从这个类派生于亚马逊的库：
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);
}
我理解亚马逊的类是旨在通过行为来代替存根ual实现，但是这是如何完成的？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'
}
}
}

我在亚马逊的没有成功开发者论坛发布posted about this呢。请让我知道你是否需要更多信息，谢谢。
