Question

我在build.gradle文件中看到一个错误消息，指出我的应用中的android库。依赖性块如下所示：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    compile 'de.hdodenhof:circleimageview:2.2.0'
    compile 'com.android.support:recyclerview-v7:27.0.2'
    compile 'com.beloo.widget:ChipsLayoutManager:0.3.7@aar'
}

我看到的信息是：

all com.android.support libraries must use the exact same version specification

显然，版本27.0.2和21.0.3

Found versions 27.0.2, 21.0.3. Examples include com.android.support:animated-vector-drawable:27.0.2 and com.android.support:support-v4:21.0.3 less... (⌘F1)

覆盖旧LIB

 dependencies {
            implementation fileTree(dir: 'libs', include: ['*.jar'])
            implementation 'com.android.support:appcompat-v7:27.0.2'
            testImplementation 'junit:junit:4.12'
            androidTestImplementation 'com.android.support.test:runner:1.0.1'
            androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
            compile 'de.hdodenhof:circleimageview:2.2.0'
            compile 'com.android.support:recyclerview-v7:27.0.2'
            compile 'com.beloo.widget:ChipsLayoutManager:0.3.7@aar'
            //overwrite old LIB
            compile 'com.android.support:support-v4:27.0.2'  

        }
