下面是代码,也就是在onCreate
功能:安卓:无法解析符号GoogleSignInOptions
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(
GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
这是我的build.gradle(项目级别)
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
这是我的构建。 gradle(应用程序级别)
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.0"
defaultConfig {
applicationId "ca.uoguelph.socs.cis3760.s2_g6"
minSdkVersion 19
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

})
compile 'com.android.support:appcompat-v7:25.1.1'
compile 'com.android.support:design:25.1.1'
compile 'com.android.support:support-v4:25.1.1'
testCompile 'junit:junit:4.12'
compile 'com.google.android.gms:play-services-appindexing:9.8.0'

我真的不知道发生了什么。先谢谢你。
