亚马逊广告api崩溃我的应用程序？

Question

无法实例化以下类： - com.amazon.device.ads.AdLayout（Open Class，Show Error Log） 有关详细信息，请参阅错误日志（窗口＆gt;显示视图）。 提示：在Eclipse中显示时，在自定义视图中使用View.isInEditMode（）来跳过代码

我的main.xml看起来像这样

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:Amazon="http://schemas.android.com/apk/lib/com.amazon.device.ads"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="top|center_horizontal" >

<com.amazon.device.ads.AdLayout  
android:id="@+id/myAdView" 
android:layout_width="fill_parent"
android:layout_height="wrap_content" />

<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

我的MainActivity.java就是这个

import com.amazon.device.ads.AdLayout;
import com.amazon.device.ads.AdRegistration;
import com.amazon.device.ads.AdTargetingOptions;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    preferences = PreferenceManager.getDefaultSharedPreferences(this);
    int defaultValue = R.drawable.blue;
    int themedefault = ThemeChanger.THEME_BLUE;
    appliedtheme = preferences.getInt("mytheme", themedefault);
    ThemeChanger.onActivityCreateSetTheme(this, appliedtheme);
    setContentView(R.layout.main);

    AdRegistration.setAppKey("Application_Key");
    this.adView = (AdLayout) findViewById(R.id.myAdView);
    this.adView.loadAd(new AdTargetingOptions());

    button1 = preferences.getInt("DigitButtonStyle", defaultValue);
    buttonmadd = preferences.getInt("MemoryButtonStyle", defaultValue);
    buttoncos = preferences.getInt("FunctionButtonStyle", defaultValue);

Answer 1

我遇到了同样的问题，并遵循亚马逊开发人员指南。要解决此问题，只需复制amazon库并将其粘贴到libs文件夹中，然后再运行。

Answer 2

这是Eclipse ADT插件中的已知问题，即使您使用View.isInEditMode（），在某些情况下，它会在最近的API版本（高于18）中崩溃。它已在Android Studio中修复。

如果您想查看布局预览，可以尝试使用低于19的不同API版本。

检查屏幕截图。它使用的是API 18.（Red box是Amazon AdLayout）
