react-native - 播放控制台中的 React Native Release 应用程序错误

问题描述

我将我的应用程序发送到了 Play 商店，在下载了一些下载之后，在 Play 控制台中出现了一些错误集群。在我的手机中，这种故障从未发生过。

播放控制台错误：

java.lang.RuntimeException: 
    at android.app.ActivityThread.handleReceiver (ActivityThread.java:3334) 
    at android.app.ActivityThread.-wrap17 (Unknown Source)

我的设置 Gradle：

    rootProject.name = project_name
    include ':react-native-firebase'
    project(':react-native-firebase').projectDir = new     File(rootProject.projectDir, '../node_modules/react-native-firebase/android')
    include ':react-native-snackbar'
    project(':react-native-snackbar').projectDir = new         File(rootProject.projectDir, '../node_modules/react-native-snackbar/android')
    include ':react-native-vector-icons'
    project(':react-native-vector-icons').projectDir = new     File(rootProject.projectDir, '../node_modules/react-native-vector-icons/android')
    include ':react-native-text-input-mask'
    project(':react-native-text-input-mask').projectDir = new     File(rootProject.projectDir, '../node_modules/react-native-text-input-    mask/android')

    include ':app'

My build.gradle

    buildscript {
    repositories {
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        jcenter()
    }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.1.3'
            classpath 'com.google.gms:google-services:4.0.1'
        }
    }

    allprojects {
        repositories {
            mavenLocal()
            maven {
                url "$rootDir/../node_modules/react-native/android"
            }
            maven {
                url 'https://maven.google.com/'
                name 'Google'
            }
            google()
            jcenter()
        }
    }

ext {
    buildToolsVersion = "26.0.3"
    minSdkVersion = 16
    compileSdkVersion = 26
    targetSdkVersion = 26
    supportLibVersion = "26.1.0"
}

我的应用程序/build.gradle

...
dependencies {
    implementation project(':react-native-firebase')
    compile project(':react-native-snackbar')
    implementation project(':react-native-vector-icons')
    compile project(':react-native-text-input-mask')
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    compile "com.facebook.react:react-native:+"  // From node_modules

    implementation "com.google.android.gms:play-services-base:15.0.1"
    implementation "com.google.firebase:firebase-core:16.0.1"
    implementation "com.google.firebase:firebase-messaging:17.1.0"
    implementation 'me.leolin:ShortcutBadger:1.1.21@aar' 

}

我不知道发生了什么以及如何解决它。谁能帮我解决这个问题？

解决方案

这看起来像一个 dex 问题。您需要启用 multidex 支持。

由于您的目标是 minSDKVersion 16，您需要将以下内容添加到您的依赖项中

implementation 'com.android.support:multidex:1.0.3'

您还需要defaultConfig在您的android/app/build.gradle

defaultConfig {
  // there will be other things here like applicationId, minSdkVersion, versionCode etc.
  multiDexEnabled true
}

MainApplication.java您还需要在from中更改以下行

public class MainApplication extends Application implements ReactApplication {

至

public class MainApplication extends MultiDexApplication implements ReactApplication {

您可以在此处阅读有关启用 multidex 的更多信息https://developer.android.com/studio/build/multidexApplication ，因为根据您是否覆盖类，有不同的方法可以启用它。
