Question

我有一个用于尝试推送通知的Android应用。到目前为止，我所拥有的只是一个简单的活动，它启动了以下检查功能：

    private boolean checkPlayServices() {
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if (resultCode != ConnectionResult.SUCCESS) {
        if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
            GooglePlayServicesUtil.getErrorDialog(resultCode, this,
                    PLAY_SERVICES_RESOLUTION_REQUEST).show();
        } else {
            out("Not Supported!");
            finish();
        }
        return false;
    }
    return true;
    }

这是来自官方教程。

应用程序构建没有错误，但是，当我尝试在模拟器或手机（galaxy S4，android 4.2.2）上运行此检查时，它会抛出NoClassDefFoundError。

这是堆栈跟踪：

我用Google搜索，据我所知，这意味着我的手机错过了Google服务APK。

我可以告诉我的应用程序在打包时包含它，还是应该在手机上安装一些东西？

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

Gradle构建脚本：

    <?xml version="1.0" encoding="utf-8"?>
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 19
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.google.android.gms:play-services:4.0.30'
}

感谢。

我有这个问题...请将SDK中的GooglePlayService项目作为依赖模块包含在您的项目中。这可能有所帮助。该项目的路径是android_sdk \ extras \ google \ google_play_services \ libproject \

设备上的NoClassDefFoundError：com.google.android.gms.common.GooglePlayServicesUtil
