React-native: OkHttp3

[Fanda36]

Hi,
I'm using RN 0.30 on Windows 10, Android Studio and I add to my project gradle this:
compile 'com.squareup.okhttp3:okhttp:3.4.1'

Then if run project return error (application won't run):
"Requested enabled DevSupportManager, but DevSupportManagerImpl class was not found or could not be created"

Now I use old version
compile 'com.squareup.okhttp3:okhttp:3.3.1'
and all work fine.

This seems like a problem with okhttp rather than a problem with React Native, unless you can isolate the problem more specifically to React Native.

[sytolk]

@lacker I have test downgrading okhttp from v3.4.1 to v3.3.1 but don`t change this exception. This issue can be easy repeated if you enable Proguard in debug build (the reason is that 64K methods limit is reached for my Android app).

"react-native": "^0.42.3"

MainApplication.java

@Override
    public void onCreate() {
        super.onCreate();
        SoLoader.init(this, /* native exopackage */ false);
        // https://github.com/airbnb/native-navigation
        ReactNavigationCoordinator coordinator = ReactNavigationCoordinator.sharedInstance;
       /* line 79*/ coordinator.injectReactInstanceManager(mReactNativeHost.getReactInstanceManager());
        coordinator.start(this);
    }

[sytolk]

Can we check if(__DEV__) and add this Proguard rule automatically? (in react-native .aar module project)

This is my fix for this issue:

buildTypes {
        debug {
            minifyEnabled true
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro", "devsupport.pro"
        }
        release {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
            signingConfig signingConfigs.config
        }
    }

devsupport.pro

-keep class com.facebook.react.devsupport.** { *; }
-dontwarn com.facebook.react.devsupport.**

Having the same issue using RN 0.44.2

Any workaround @sytolk ? Your fix proposal didn't worked for me.

[iegik]

same on RN 0.42.3

[JeffreyLeeSpokeo]

This is happening to me as well something about "Requested enabled DevSupportManager, but DevSupportManagerImpl class was not found or could not be created". It happens when I build the react native instance manager

[manishoo]

I'm having the same issue on RN 48. It has no problems on android 7+ but in 4.4.4 it crashes. why is this issue closed ?

[iegik]

@mehdijjz try to update Gradle.

[andfk]

Updating Gradlle like @iegik suggest, didn't solves this issue (at least for me).

[iegik]

@andfk, try this: https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

buildscript {
    repositories {
        ...
        // You need to add the following repository to download the
        // new plugin.
        google()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta4'
    }
}

[Jobeso]

Got the same issue described by @mehdijjz

[andfk]

many thanks @iegik

[Jobeso]

sadly @iegik `s fix is not working for me

[teyou]

same issue for me.. only happens on Android 4 version

[swarna-sathya]

Same issue for me well. The usecase is as mentioned by @sytolk
Happens when I enable Proguard in Debug build.
Is there a workaround for it? Can the issue be reopened please?

[ou2s]

Same issue here on 0.48.4

[ou2s]

I did not manage to achieve Gradle migration to 3.x

So I tried to enable MultiDexApplication as advised by this link and it worked for me :)

I solved it by adding compile 'com.android.support:multidex:1.0.0' to app/build.gradle and changing extends Application to extends MultiDexApplication in NavigationApplication.java

[josepht1]

This solution worked for me. I don't know why it doesn't manifest itself in the Debug mode.
Thanks for your help ou2s.

[KenChoi1992]

@sytolk It worked！Thanks for help.

[jayporta]

The link posted by @ou2s also worked in my case. My app has multidex and proguard enabled, but the app only crashed on one phone in our office (Galaxy Note running 4.4.1). Other devices ran without adding to dependencies and changing extends Application to extends MultiDexApplication.
