android - Google Play 服务客户端错误

Question

我一直在努力让这个 android 项目在带有 gradle 的 android studio 中工作。我对这一切还很陌生，所以这可能是一个简单的问题，但我已经花了好几天时间，无法克服我在尝试运行我的项目时收到的这个错误:

Error:(25, 62) error: package com.google.android.gms.common.GooglePlayServicesClient does not exist
Error:(26, 62) error: package com.google.android.gms.common.GooglePlayServicesClient does not exist
Error:(27, 39) error: cannot find symbol class LocationClient
Error:(42, 60) error: cannot find symbol class ConnectionCallbacks
Error:(43, 3) error: cannot find symbol class OnConnectionFailedListener
Error:(82, 10) error: cannot find symbol class LocationClient
Error:(586, 26) error: cannot find symbol class LocationClient
Error:(618, 2) error: method does not override or implement a method from a supertype
Error:(627, 2) error: method does not override or implement a method from a supertype
Error:(635, 2) error: method does not override or implement a method from a supertype

Error:Execution failed for task ':compileDebugJava'.

这是错误来源文件的顶部(我已标记有问题的行):

它说:“无法解析符号”

这是我的 build.gradle 文件:

// NOTE: Do not place your application dependencies here; they
// belong in the individual module build.gradle files
            }
        }

allprojects {
    repositories {
        jcenter()
    }
}


apply plugin: 'com.android.application'

dependencies {

    compile 'com.android.support:appcompat-v7:22.0.0'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:7.0.0'

}

android {

    buildToolsVersion "22"
    compileOptions.encoding = 'windows-1251'

    defaultConfig {

        minSdkVersion 19
        targetSdkVersion 22
        versionCode 2
        versionName "2.0"
    }


    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']

            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

在我看来，google play 服务链接存在问题。我遵循了几个不同的示例，并且肯定已经下载了它，但我无法让它工作。此外，我感觉我的 list (不确定 sdk 版本的正确目标)和 gradle 文件(jcenter 或 maven？并设置适当的依赖项)可能配置不正确。

这方面的任何帮助都会很棒我过去几天一直在搜索互联网，但我无法解决我确信这是一个简单的问题...

Answer 1

如果您使用的是 Google Play Services 7.0.0，您只需更改

import com.google.android.gms.common.GooglePlayServicesClient.ConnectionCallbacks;
import com.google.android.gms.common.GooglePlayServicesClient.OnConnectionFailedListener;

到

import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;

如果您覆盖了 onDisconnected 方法，您还应该删除它。
