i add the new gradle:

}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

compile 'com.roomorama:caldroid:3.0.1'
compile 'com.android.support:design:25.0.1'
testCompile 'junit:junit:4.12'
}
如果我使用这个sdk版本,编译'com.roomorama:caldroid:3.0.1'就不起作用了。java类找不到caldroid
谢谢尝试将sdk更新为最新版本,因为编译sdk版本和生成工具版本不同

清理项目,然后重新启动android studio。我通过以下方法解决了它: 文件菜单-->使缓存无效/重新启动 在警告窗口-->中,选择“无效/重新启动” 这解决了我的问题,我保留了gradle配置:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion '25.0.1'
defaultConfig {
applicationId "com.example.garcia.coachtrain"
minSdkVersion 21
targetSdkVersion 23
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(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.squareup.okhttp3:okhttp:3.3.0'
compile 'com.roomorama:caldroid:3.0.1'
compile 'com.android.support:design:23.0.1'
testCompile 'junit:junit:4.12'
}
因为您的编译器DKVersion 23 buildToolsVersion“25.0.1”不相同,我将编译器DKVersion 23 buildToolsVersion“25.0.1”更改为编译器DKVersion 23 buildToolsVersion“23.0.0”,但它不起作用。Nidhin kumar,昨天我的项目工作正常,所以我认为这不是问题所在。试着重建这个项目一次又一次,我试着重建,但都是一样的。我快疯了
