无法访问ActivityCompatApi23类 [英] Cannot access ActivityCompatApi23 class

问题描述

我的gradle文件遇到运行时问题。我将这个 compile'c​​om.google.android:flexbox:0.3.1'作为编译时间依赖项添加到我的Gradle文件中。我遇到了一个错误，并将其添加到我的项目级别的Gradle文件中。

  maven {
 urlhttps：// maven.google.com

  

在添加上面的

  allprojects {
存储库{
 jcenter（）
 maven {
 url https://maven.google.com

} 
} 
  

在我的应用程序级别的Gradle文件中添加上面的内容后，我正在尝试运行我的应用程序时遇到了另一个错误。所以我按照SO的一些答案完成了以下内容。

1. 尝试了一个Clean和Rebuild。



2. 导航到 projectname \ .idea \ libraries 路径，并删除包含当前版本以外的支持库版本的文件 25.3.1
   3.为了解决这个错误，我进一步从我的应用程序级别的Gradle文件中删除了这一行，
   
   

   androidTestCompile （'com.android.support.test.espresso：espresso-core：2.2.2'，{
   exclude group：'com.android.support'，module：'support-annotations'
   }）
   
   
   现在最后的Gradle文件看起来像这样，并带有错误，
   
   

   错误：
   
   

    错误：（28，8）错误：无法访问ActivityCompatApi23 
    class for android .support.v4.app.ActivityCompatApi23未找到
     

   我的Gradle文件

     apply plugin：'com.android.application 
    
    android {
    compileSdkVersion 25 
    buildToolsVersion25.0.3
    defaultConfig {
    applicationIdcom.example.test
    minSdkVersion 19 
    targetSdkVersion 25 
    versionCode 1 
    versionName1.0
    testInstrumentationRunnerandroid.support.test.runner.AndroidJUnitRunner
    vectorDrawables.useSupportLibrary = true 
   } 
    buildTypes {
    release {
    minifyEnabled false 
    proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard-rules.pro'
   } 
    } 
   } 
    
   依赖关系{
   编译fileTree（包括：['* .jar']，dir：'libs'）
    
   编译'com .android.support：appcompat-v7：25.3.1'
    compile'c​​om.android.support:design:25.3.1'
    compile'c​​om.android.support:cardview-v7:25.3.1 '
    compile'c​​om.android.support:support-v4:25.3.1' 
   编译'com.google.android:flexbox:0.3.1'
   编译'uk.co.chrisjenx：书法：2.3.0'
    testCompile'junit：junit：4.12'
    
     

   
   

   解决方案

   > compileSdkVersion 等于25，而 0.3.1 版本的Flexbox布局使用支持库版本 26.0.0 - 这是一个问题， compileSdkVersion 应该与支持库的主要版本匹配。
   
   

   将项目升级到26或使用依赖于flexbox版本的版本在sdk 25上，它似乎是v0.2.7：
   
   

     compile'c​​om.google.android:flexbox:0.2.7' 
     

   
   

   I am having runtime problems with my gradle file. I added this compile 'com.google.android:flexbox:0.3.1' as a compile time dependency to my Gradle file. I encountered an error and added this in my project level Gradle file.

   maven {
               url "https://maven.google.com"
           }
   

   Which finally looked liked this after adding the above

   allprojects {
       repositories {
           jcenter()
           maven {
               url "https://maven.google.com"
           }
       }
   }
   

   After adding the above in my app level Gradle file I am now encountering a different error when I am trying to run my app. So I did the following as per some answers from SO.

   1. Tried a Clean and Rebuild.

   2. Navigated to the path projectName\.idea\libraries and deleted the files that contained the support library version other than the current versions 25.3.1 3.In order to solve the error I further removed this line from my app level Gradle file,

      androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' })

   Now the final Gradle file looks like this with the error,

   Error:

   Error:(28, 8) error: cannot access ActivityCompatApi23
   class file for android.support.v4.app.ActivityCompatApi23 not found
   

   My Gradle file

   apply plugin: 'com.android.application'
   
   android {
       compileSdkVersion 25
       buildToolsVersion "25.0.3"
       defaultConfig {
           applicationId "com.example.test"
           minSdkVersion 19
           targetSdkVersion 25
           versionCode 1
           versionName "1.0"
           testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
           vectorDrawables.useSupportLibrary = true
       }
       buildTypes {
           release {
               minifyEnabled false
               proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
           }
       }
   }
   
   dependencies {
       compile fileTree(include: ['*.jar'], dir: 'libs')
   
       compile 'com.android.support:appcompat-v7:25.3.1'
       compile 'com.android.support:design:25.3.1'
       compile 'com.android.support:cardview-v7:25.3.1'
       compile 'com.android.support:support-v4:25.3.1'
       compile 'com.google.android:flexbox:0.3.1'
       compile 'uk.co.chrisjenx:calligraphy:2.3.0'
       testCompile 'junit:junit:4.12'
   }
   

   解决方案

   You have declared compileSdkVersion equal to 25, whereas 0.3.1 version of flexbox layout uses support libs version 26.0.0 - that's a problem, compileSdkVersion should match support libs major version.

   Either upgrade your project to 26 or use a version of flexbox layout that relies on sdk 25, which seems to be v0.2.7:

   compile 'com.google.android:flexbox:0.2.7'
