【问题描述】：

我正在尝试向 react-native 项目添加推送通知系统，并且尝试使用 react-native-notifications 2.1.3 版。

我的 package.json 文件如下所示：

"dependencies": {
    "@react-native-community/async-storage": "^1.6.3",
    "jetifier": "^1.6.4",
    "react": "16.8.6",
    "react-native": "0.60.0",
    "react-native-camera": "^3.11.1",
    "react-native-elements": "^1.2.7",
    "react-native-gesture-handler": "^1.5.1",
    "react-native-notifications": "^2.1.3",
    "react-native-permissions": "^2.0.3",
    "react-native-qrcode-scanner": "^1.3.1",
    "react-native-vector-icons": "^6.6.0",
    "react-navigation": "^1.0.0-beta.27",
    "react-redux": "^5.1.2",
    "redux": "^4.0.4",
    "redux-thunk": "^2.3.0",

  },
  "devDependencies": {
    "@babel/core": "7.5.0",
    "@babel/runtime": "7.5.0",
    "@react-native-community/eslint-config": "0.0.3",
    "babel-jest": "24.8.0",
    "eslint": "6.0.1",
    "jest": "24.8.0",

    "react-test-renderer": "16.8.6"
  },
  "jest": {
    "preset": "react-native"
  }
}

我的项目级 build.gradle(android/build.gradle) 看起来像

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.4.1")

        classpath 'com.google.gms:google-services:4.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }

        google()
        jcenter()
    }
}
subprojects { subproject ->
    afterEvaluate {
        if ((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
            android {
                variantFilter { variant ->
                    def names = variant.flavors*.name
                    if (names.contains("reactNative59")) {
                        setIgnore(true)
                    }
                }
            }
        }
    }
}

MainApplication.java 片段：

protected List<ReactPackage> getPackages() {
      @SuppressWarnings("UnnecessaryLocalVariable")
      List<ReactPackage> packages = new PackageList(this).getPackages();
      // Packages that cannot be autolinked yet can be added manually here, for example:
      // packages.add(new MyReactNativePackage());
      return packages;
    }

取自 PackageList.java（MainApplication getPackages() 返回的内容）

public ArrayList<ReactPackage> getPackages() {
    return new ArrayList<>(Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      new AsyncStoragePackage(),
      new RNCameraPackage(),
      new RNGestureHandlerPackage(),
      new RNPermissionsPackage(),
      new VectorIconsPackage(),
      new RNFetchBlobPackage()
    ));
  }

我知道上面的大部分代码都不需要，但我提供了以防我错过了什么。

我的问题是我的项目的 minSDK 版本为 16，但 react-native-notifications 的 minSDK 版本为 19。尝试构建时，我得到以下输出：

* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [:react-native-notifications] Project-Root\node_modules\react-native-notifications\an
droid\app\build\intermediates\library_manifest\reactNative60Debug\AndroidManifest.xml as the library might be using APIs not available in 16
        Suggestion: use a compatible library with a minSdk of at most 16,
                or increase this project's minSdk version to at least 19,
                or use tools:overrideLibrary="com.wix.reactnativenotifications" to force usage (may lead to runtime failures)

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

我在网上查找了解决方案，但我尝试将 react-native-notifications minSDK 版本下移至 16，但未成功。

当我尝试将项目的 minSDK 更改为 19 时，我得到了

error Failed to install the app. Make sure you have the Android development environment set up: https://facebook.github.io/react-native/docs/getting-started.html#android-development-environment. Run CLI with --verbose flag for more de

如果有人能帮我解决这个问题，我将不胜感激。

【解决方案1】：

您必须传递应用程序上下文。作为参考检查这个https://github.com/wix/react-native-notifications/blob/master/docs/installation.md#-android

【讨论】：

这真的没有帮助。我对使用 react 还很陌生，但是该文档中有关 android 的说明看起来像手动链接过程，我认为 react 0.60.0 已将其丢弃。
忽略我之前的评论。我忘记包含传递上下文的 MainApplication.java 文件代码。它抛出了这个错误，因为我需要手动链接库。

【解决方案2】：

我找到了解决办法。

我将项目的 minSDKVersion 更改为 19，手动链接库

react-native link react-native-notifications

然后我在项目的根目录中创建了一个新文件 (react-native.config.js)，其中仅包含

module.exports = {
  dependencies: {
    'react-native-notifications': {
      platforms: {
        android: null
      },
    },
 },
}
