React-native 应用程序在真正的 Android 设备上崩溃 [英] React-native app crashes on real android device

问题描述

我正在使用 react-native，目前开始使用 redux 并创建了一个应用程序，但是当我在模拟器上运行该应用程序时，它运行良好.然后我通过 USB 将我的手机与 android 6 连接，它也在工作.但是在 Android 8 的其他设备中它不起作用然后我将 targetSdkVersion 更改为 28 然后它也不起作用我不明白是什么问题.

以下是我的 package.json

<代码>{"name": "演示",版本":0.0.1"，私人":真的，脚本":{"start": "节点 node_modules/react-native/local-cli/cli.js start",测试":开玩笑"},依赖关系":{反应":16.6.3"，反应原生":^0.57.8"，"react-native-flash-message": "^0.1.10","react-native-linear-gradient": "^2.5.3","react-native-modal-datetime-picker": "^6.0.0","react-native-navigation": "^2.8.0","react-native-tab-view": "^1.3.2","react-native-vector-icons": "^6.2.0","react-redux": "^6.0.1","redux": "^4.0.1","redux-thunk": "^2.3.0"},开发依赖":{"babel-core": "^7.0.0-bridge.0","babel-jest": "24.0.0","jest": "24.0.0","metro-react-native-babel-preset": "0.51.1",反应测试渲染器":16.6.3"},开玩笑":{预设":反应原生"}}

android/build.gradle

buildscript {分机{buildToolsVersion = "28.0.3"minSdkVersion = 19compileSdkVersion = 28目标SDK版本= 28supportLibVersion = "28.0.0"}存储库{谷歌()行家本地()MavenCentral()jcenter()}依赖{类路径 'com.android.tools.build:gradle:3.2.1'//注意:不要将您的应用程序依赖项放在这里；他们属于//在单独的模块 build.gradle 文件中}}所有项目{存储库{谷歌()MavenCentral()行家本地()jcenter()行家{//所有 React Native(JS、Obj-C 源代码、Android 二进制文件)都是从 npm 安装的url "$rootDir/../node_modules/react-native/android"}maven { url 'https://jitpack.io' }}}任务包装器(类型:包装器){gradleVersion = '4.7'distributionUrl = distributionUrl.replace("bin", "all")}子项目 { 子项目 ->后评价{if ((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {安卓 {变体过滤器 { 变体 ->定义名称=变体.flavors*.nameif (names.contains("reactNative51") || names.contains("reactNative55")) {设置忽略(真)}}}}}}

我不明白问题出在哪里.提前致谢

然后重新启动应用程序.

I am using react-native and currently started using redux and created one app but when I am running that app on the emulator it is working fine. Then I connected my mobile with android 6 through USB on that also it is working. But in other devices of Android 8 it is not working then I have changed targetSdkVersion to 28 then also it not working I am not getting what is the problem.

Following is my package.json

{
  "name": "Demo",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },

    "react-test-renderer": "16.6.3"
  },
  "jest": {
    "preset": "react-native"
  }
}

android/build.gradle

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 19
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        mavenLocal()
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

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

allprojects {
    repositories {
        google()
        mavenCentral()
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven { url 'https://jitpack.io' }
    }
}


task wrapper(type: Wrapper) {
    gradleVersion = '4.7'
    distributionUrl = distributionUrl.replace("bin", "all")
}

subprojects { subproject ->
    afterEvaluate {
        if ((subproject.plugins.hasPlugin('android') || subproject.plugins.hasPlugin('android-library'))) {
            android {
                variantFilter { variant ->
                    def names = variant.flavors*.name
                    if (names.contains("reactNative51") || names.contains("reactNative55")) {
                        setIgnore(true)
                    }
                }
            }
        }
    }
}

I am not getting where is the problem. Thanks in advance

From the logs that Ahtesham Shah provided in the above chat.

These suggest that the error is related to the following react-native issue. Where react-native doesn't support 64-bit on Android.

There is a solution to the problem that should be added to the app/build.gradle. The solution is to define the packaging options. This can be done like so.

android {
  ...
  // add the following packagingOptions 
  packagingOptions {
    pickFirst 'lib/x86_64/libjsc.so'
    pickFirst 'lib/arm64-v8a/libjsc.so'
  }
}

We also added the following to the defaultConfig in the app/build.gradle

ndk {
  abiFilters 'armeabi-v7a', 'x86'
}

Then we cleaned the build.

Then restarted the app.
