添加 realm 以反应原生后 Apk 崩溃

Question

Thanks in advance.

I tried to install Realm 3.3.0 on react native and after generating the build when the app opens it crashes. I use

"react": "16.8.6",
"react-native": "0.60.5"

My gradle are

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 21
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.4.1")
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

I put up the log cat and i am getting the following;

Is there any work around for this??

Answer 1

I use realm in my daily work, I have met this issue is because realm doesn't support hermes engine yet, see this issue , you need to change enableHermes to false in file android/app/build.gradle

project.ext.react = [
    entryFile: "index.js",
    enableHermes: false,
]

if you are using 0.60.0 or greater version the step to install realm is

1. npm i realm

2. npx react-native link realm , realm's autolink is not working yet, yes, you need link manually with command

3. npx jetify

no need to edit MainAplication.java or other file to link more
