Question

仅将我的应用迁移到androidx上，就无法解决此错误。我只是在npx react-native run-android执行结束时收到的，这中断了应用程序。该错误看起来像这样：

java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/swiperefreshlayout/widget/SwipeRefreshLayout;

我已经尝试过清理，重建，使用依赖版本的操作，但是无法克服这一问题。

            signingConfig signingConfigs.release
        }
    }
    // applicationVariants are e.g. debug, release
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            // For each separate APK per architecture, set a unique version code as described here:

            def abi = output.getFilter(OutputFile.ABI)
            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
            }
        }
    }
}

    implementation "com.google.android.gms:play-services-base:16.0.1"
}

// Run this once to be able to run the application with BUCK

task copyDownloadableDepsToLibs(type: Copy) {
    from configurations.compile
    into 'libs'
}

apply plugin: 'com.google.gms.google-services'

这是我的build.gradle文件。我真的不知道该怎么办。滑动刷新工作正常，直到androidx迁移为止。

非常感谢您提供任何有用的信息或建议。

我找到了解决方案。问题与“反应本机”屏幕有关。

将以下两行添加到android / app / build.gradle中的“ dependencies”部分。

implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0-alpha02'
