我开发的Android应用程序涉及使用GoogleApiClientBuilder类对用户进行身份验证。当我点击我的代码的这部分时,错误发生在运行时:
GoogleApiClient.Builder builder = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(Plus.API)
.addScope(Plus.SCOPE_PLUS_LOGIN);
这在Android 5.0.1上完全正常,但是当我在API级别19(Kitkat)上尝试时,我收到此错误:
java.lang.NoClassDefFoundError: com.google.android.gms.internal.zzpt$zza

在做了一些研究后,我发现它可能是Proguard剥离了必要的类,但无论我是启用还是禁用minifyEnabled,它都不起作用:
buildTypes {
release {
minifyEnabled = true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
然后我做了一些更多的研究,并认为它可能是一个multiDex问题,但我启用了它,我甚至将它编译为我的依赖项之一
defaultConfig {
applicationId "com.tubealert.tubealert"
minSdkVersion 17
targetSdkVersion 22
versionCode 1
versionName "1.0"
multiDexEnabled = true
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
configurations { all*.exclude group: 'com.google.guava', module: 'guava' }
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:cardview-v7:21.0.0'
compile 'com.android.support:recyclerview-v7:22.+'
compile 'com.android.support:support-v4:22.2.0'
compile 'com.android.support:multidex:1.0.0'
compile 'com.google.android.gms:play-services:7.5.0'
compile 'com.google.apis:google-api-services-youtube:v3-rev134-1.20.0'
compile 'com.google.gdata:core:1.47.1'
}
所以不,它只适用于棒棒糖但不低于此......如果可以,请帮助我!

想出来。只需按照设置谷歌播放服务的每一步!我的愚蠢错误。
