Question

在我将SDK从27更改为28，并更改了gradle中的某些依赖项以解决清单合并的问题后，我遇到了

的错误

程序类型已存在：android.support.v4.app.INotificationSideChannel

这是我的build.gradle

android {
    compileSdkVersion 28
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

Answer 1

我相信这是因为 com.google.firebase 暂时依赖于 com.android.support:support-v4 。为了解决这个问题，您应该可以在 gradle.properties 文件中设置 android.enableJetifier = true ，该文件将“自动转换现有的第三方库，就像编写它们一样适用于AndroidX”-https://developer.android.com/studio/preview/features/#androidx_refactoring。希望会有所帮助！

Answer 2

我终于找到了答案。问题在于以下依赖性

 implementation 'com.github.chrisbanes:PhotoView:2.3.0'

我将其更改为以下

  implementation 'com.commit451:PhotoView:1.2.4'

它给了我所需的缩放属性

从SDK 27更新到28后，程序类型已经存在
