我一直在尝试让这个Android项目在带有gradle的android studio中运行。我对这一切都很陌生,所以这可能是一个简单的问题,但我已经花了很多天,并且无法克服我在尝试运行项目时收到的错误:
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

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'
compile files('libs/android-support-v4.jar')
}
android {
compileSdkVersion 22
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']
aidl.srcDirs = ['src']
renderscript.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')
}
}

在我看来谷歌播放服务链接存在问题。我已经关注了几个不同的例子并确实将其下载但我无法让它工作。另外我感觉我的清单(不确定sdk版本的正确目标)和gradle文件(jcenter或maven?并设置正确的依赖项)可能配置不正确。
任何有关这方面的帮助都会很棒我过去几天都在搜索互联网,但我无法解决我确定的简单问题...
答案 0 :(得分:12)
如果您使用的是Google Play Services 7.0.0,则只需更改
即可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;
如果你覆盖它,你也应该删除onDisconnected方法。
答案 1 :(得分:5)
您的位置实施基于较早版本的Google Play服务,但您导入了Play服务7.0.0&#34; GooglePlayServicesClient&#34;不再存在。
您可以在build.gradle文件中将播放服务版本更改为旧版本 要么 您可以使用this示例进行较新的位置实施。

非常有趣,我继续潜伏着鼹鼠,并发现有人建议这个敌人在gradle构建中依赖:
compile 'com.android.support:appcompat-v7:20.0.0'
compile 'com.google.android.gms:play-services:4.+'
compile 'com.android.support:cardview-v7:21.0.0'
compile 'com.android.support:recyclerview-v7:21.0.0'
不确定是什么样的cardview或者回收者视图,但游戏服务是一个相当低的版本。但该死的东西建立了!现在唯一的问题是,只要您尝试打开它,应用程序就会在模拟器中崩溃(不幸的是它已经停止了消息)。我想知道这是一个新问题,还是我的配置还没有关闭?
