Use implementation 'com.android.support:appcompat-v7:27.1.1'instead of implementation 'com.android.support:appcompat-v7:26.1.0'and change compileSdkVersion 26 to 27
使用implementation 'com.android.support:appcompat-v7:27.1.1'代替implementation 'com.android.support:appcompat-v7:26.1.0'并将 compileSdkVersion 26 更改为 27

Add these lines within your app dependenciesbraces,
在您的应用程序依赖项大括号中添加这些行，
android{
configurations.all {
resolutionStrategy.force 'com.android.support:support-annotations:27.1.1'
}
}
Latest is 27.1.1 upto this date.
到目前为止，最新的是 27.1.1。

Add This Code to the bottom of build.gradle at app level. It will work...
将此代码添加到应用级别的 build.gradle 底部。它会工作...
configurations.all {
resolutionStrategy.eachDependency{
DependencyResolveDetails details ->
def requested=details.requested
if(requested.group=="com.android.support"){
if(!requested.name.startsWith("multidex")){
details.useVersion("26.0.1")

Well, I too faced the same problem here is how I fixed it
好吧，我也遇到了同样的问题，这就是我如何修复它
- Goto app level Gradle file
- 转到应用级 Gradle 文件
There you will find what are all the config's you have set up. In my case here
在那里你会找到你设置的所有配置。就我这里而言
android{
**compileSdkVersion 26**
defaultConfig {
applicationId "com.xxxxxxxxxxx.yyyyyyyy.zzz"
minSdkVersion 19
**targetSdkVersion 26**
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
**implementation 'com.android.support:appcompat-v7:26.1.0'**
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
So here just change the compileSdkVersion & targetSdkVersion from 26 to 27 and
所以这里只需将 compileSdkVersion & targetSdkVersion 从 26 更改为 27 和
from dependencies change support appcomat
从依赖项更改支持应用程序
from implementation 'com.android.support:appcompat-v7:26.1.0'
to implementation 'com.android.support:appcompat-v7:27.1.1'
android {
**compileSdkVersion 27**
defaultConfig {
applicationId "com.xxxxxxxxxxx.yyyyyyyy.zzz"
minSdkVersion 19
**targetSdkVersion 27**
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
**implementation 'com.android.support:appcompat-v7:27.1.1'**
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

This is due to there is no dependency added to your App build.gradle or might be its an old version. So, add a dependency for annotation support.
这是因为您的 App build.gradle 没有添加依赖项，或者可能是旧版本。因此，添加注释支持的依赖项。
implementation 'com.android.support:support-annotations:27.1.1'
Here I have added annotation version 27.1.1 to solve your error if this is mismatched with different version then change it to the required version.
在这里，我添加了注释版本 27.1.1 来解决您的错误，如果这与不同版本不匹配，则将其更改为所需的版本。
