我使用的是react native,目前已开始使用redux并创建了一个应用程序,但当我在模拟器上运行该应用程序时,它工作正常。然后我通过USB将我的手机连接到Android 6上,它也在工作。但是在android 8的其他设备中,它不工作,然后我将targetsdkversion更改为28,然后它也不工作,我不知道问题是什么。

下面是my package.json

{

"name": "Demo",

"version": "0.0.1",

"private": true,

"scripts": {

"start": "node node_modules/react-native/local-cli/cli.js start",

}

安卓/build.gradle

buildscript {

ext {

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)

}

}

}

}

}

}

我不知道问题在哪里。提前谢谢
