【问题描述】：
我从稳定版更新到 Android Studio 2.1。一旦我这样做了，我的登录类就会得到 ClassNotFoundException，它在清单中声明了很长时间。在更新之前，我的应用程序编译良好。

这是我的 gradle.build
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 'Google Inc.:Google APIs:23'
buildToolsVersion "22.0.1"
defaultConfig {
applicationId "com.myapp"
minSdkVersion 14
targetSdkVersion 22
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}
dependencies {
// compile files('libs/smack-core-4.0.7.jar')
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.google.android.gms:play-services:7.8.0'
compile 'com.google.maps.android:android-maps-utils:0.4+'
}
到目前为止，我已经尝试过 1）清理和重建项目 2）删除构建文件夹并重建项目/重新启动Android Studio 3）切换到金丝雀频道以及开发频道并更新 4）在设置中勾选和取消勾选离线模式 显然这是一个错误，但是有解决方案吗？如何撤消最近的更新？任何帮助深表感谢。
【问题讨论】：
-
compileSdkVersion '23' buildToolsVersion "23.0.1" -
升级到Android Studio 2.1后你更新了com.android.tools.build:gradle版本了吗？
-
您是否尝试禁用即时运行并运行您的项目？
