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/重启AndroID Studio
3)切换到金丝雀频道以及开发频道和更新
4)在“设置”中选中并取消选中离线模式
显然这是一个错误,但有解决方案吗？如何撤消最近的更新？任何帮助深表感谢.

解决方法 试试这个：

清除应用缓存

清除应用数据

卸载应用

再次运行/调试

希望它有效！
