ClassNotFoundException的:没有找到类" com.google.android.gms.ads.AdView" [英] ClassNotFoundException: Didn't find class "com.google.android.gms.ads.AdView"
问题描述
我做了很多的研究,这似乎是一个常见的错误对于许多用户,但非常不同的原因。其中无我发现很适合我。
我收到
了java.lang.RuntimeException:无法启动活动ComponentInfo {
[...] / [...] activities.StartActivity}:android.view.InflateException:
二进制XML文件行#173:错误充气类[...] BannerAd
[...]
致:android.view.InflateException:二进制XML文件中的行#8:错误
充气类com.google.android.gms.ads.AdView
[...]
抛出java.lang.ClassNotFoundException:产生的原因没有找到类
在路径com.google.android.gms.ads.AdView:DexPathList [zip文件
/data/app/[...]-1.apk"],nativeLibraryDirectories=[/data/app-lib/[...]-1,
/供应商/ lib中/系统/ lib目录]
我在安装ADT和SDK软件包的最新版本。我复制了谷歌播放的,services_lib到我的工作区和进口它作为一个Android项目。我增加一条,作为一个库我的应用程序的项目。我在排序和导出。
检查一切我有一个banner_ad.xml:
<的LinearLayout
的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =FILL_PARENT
机器人:layout_height =WRAP_CONTENT
机器人:layout_gravity =center_horizontal |顶

< / LinearLayout中>
和我正在使用BannerAd.java:

进口android.util.AttributeSet;
进口android.view.LayoutInflater;
进口android.widget.LinearLayout;

进口[...] general.Settings。

进口com.google.android.gms.ads.AdView;
公共类BannerAd扩展的LinearLayout {
公共BannerAd(上下文的背景下,ATTRS的AttributeSet){
超(背景下,ATTRS);
如果(!Settings.PRO){
LayoutInflater mInflater =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mInflater.inflate(R.layout.banner_ad,这一点,真正的);
AD浏览报AD浏览报=(AD浏览报)this.findViewById(R.id.adView);
AdRequest adRequest =新AdRequest.Builder()建立()。
adView.loadAd(adRequest);
}
}
}
难道必须是与ProGuard的?我不知道,这是我的ProGuard-project.txt文件,但是:
#为ProGuard的在你的项目中,编辑project.properties
#为在该文件中描述的定义proguard.config财产。
#
#添加项目的具体ProGuard的规则在这里。
#默认情况下,该文件中的标志被附加到指定的标志
#在$ {sdk.dir} /tools/proguard/proguard-android.txt
#您可以编辑通过改变ProGuard的包含路径和秩序
#包括project.properties财产。
#
#详情请参阅
#http://developer.android.com/guide/developing/tools/proguard.html
#添加任何具体项目保持选择这里:
#如果你的项目使用的WebView与JS,取消以下
#并指定完全限定类名给JavaScript接口
# 类:
#-keepclassmembers类fqcn.of.javascript.interface.for.webview {
# 上市 *;
#}
-keep类*扩展java.util.ListResourceBundle {
保护的对象[] [] getContents();
}
-keep公共类com.google.android.gms.common.internal.safeparcel.SafeParcelable {
公共静态最终*** NULL;
}
-keepnames @ com.google.android.gms.common.annotation.KeepName类*
-keepclassmembernames类* {
@ com.google.android.gms.common.annotation.KeepName *;
}
-keepnames类*实现android.os.Parcelable {
公共静态最后的** CREATOR;
}
任何想法我可以尝试解决这一问题?
编辑:有时候,我也得到这样的输出在控制台(我每次编译但不是,只是有时):

我做了@ user1684030所说的(升级后的Android SDK构建工具;改变编译器1.7),但不是为我工作。我已经写了我的情况下,发现它可以帮助任何人以同样的问题的解决方案:
在设置谷歌播放服务说:
在你的应用程序的项目,参照谷歌Play业务库项目。 请参阅引用库项目为Eclipse的更多信息 如何做到这一点。
注意:您要引用的库您复制一个副本 您的开发工作区,你不应该引用库 直接从Android SDK目录
解决方案:不要做手工复制。相反,只是检查了Eclipse中的盒子,上面写着复制项目到工作区
我做到了,那么,一切重新工作。
由于这个计算器的问题:<一href="http://stackoverflow.com/questions/14142496/how-to-fix-google-play-services-2-library-install-to-eclipse">How修复谷歌播放服务2库安装到Eclipse (Admob的是谷歌播放服务的一部分)
I did a lot of research and this seems to be a common error for many users but for very different reasons. None of which I found worked for me.
I'm getting
java.lang.RuntimeException: Unable to start activity ComponentInfo{
[...]/[...].activities.StartActivity}: android.view.InflateException:
Binary XML file line #173: Error inflating class [...].BannerAd
[...]
Caused by: android.view.InflateException: Binary XML file line #8: Error

"com.google.android.gms.ads.AdView" on path: DexPathList[[zip file
"/data/app/[...]-1.apk"],nativeLibraryDirectories=[/data/app-lib/[...]-1,
/vendor/lib, /system/lib]]
I'm having the newest versions of ADT and SDK packages installed. I copied google-play-services_lib to my workspace and imported it as a Android project. I added it as a library to my app project. I checked everything under "Order and Export".
I'm having a banner_ad.xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|top"
android:orientation="vertical" >
<com.google.android.gms.ads.AdView
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="@+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="[...]" />
</LinearLayout>
And a BannerAd.java which I am using:
package [...];
import android.content.Context;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.widget.LinearLayout;
import [...].R;
import [...].general.Settings;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
public class BannerAd extends LinearLayout {
public BannerAd(Context context, AttributeSet attrs) {
super(context, attrs);
if (!Settings.PRO) {
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mInflater.inflate(R.layout.banner_ad, this, true);
AdView adView = (AdView) this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
}
}
}
Could it have something to do with proguard? I have no idea, this is my proguard-project.txt file, however:
# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}
-keep class * extends java.util.ListResourceBundle {
protected Object[][] getContents();
}
-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
public static final *** NULL;
}
-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
@com.google.android.gms.common.annotation.KeepName *;
}
-keepnames class * implements android.os.Parcelable {
public static final ** CREATOR;
}
Any ideas what I could try to fix this?
Edit: Sometimes, I also get such output in the console (but not every time I compile, only sometimes):

I did what @user1684030 said (upgraded Android SDK Build Tools; changed compiler to 1.7), but not worked for me. I've written the solution that I found in case it could help anyone with the same problem:
In the step 3 of Setting Up Google Play Services says:
In your app project, reference Google Play services library project. See Referencing a Library Project for Eclipse for more information on how to do this.
Note: You should be referencing a copy of the library that you copied to your development workspace—you should not reference the library directly from the Android SDK directory.
Solution: Don't do the copy manually. Instead just check the box in Eclipse that says "Copy projects into workspace"
I did it so and everything worked again.
Thanks to this StackOverFlow question: How to fix Google Play Services 2 Library install to Eclipse (Admob is part of Google Play Services)
