Reproducible Demo

http://facebook.github.io/react-native/docs/integration-with-existing-apps

following the above link in order to make demo of how to call react native component inside a native app (android)

[hey99xx]

I don't understand what version of RN you used from the environment info, but I found that this issue was already fixed #6152 and 3640080 I guess you're on an older version and need to update.

[sunnylqm]

Usually, this means that you need to update your support library. Before it should be updated in sdk manager, and now it is distributed on remote https://developer.android.com/topic/libraries/support-library/setup

[reemtariqq]

@hey99xx no this was using latest version of react-native in both

[hey99xx]

In your stacktrace there's a class called ReactInstanceManagerImpl. That class was deleted in 2016 in 1a690d5. I cannot see how this stacktrace can belong to a recent version of RN.

[reemtariqq]

the :+ in gradle file wasn't placing the latest react native version so i've to add it explicitly in the gradle file and everything worked fine after it

[sandeepsmartest]

Please help!!
@reemtariqq i tried your solution but it did not help me.This is how my gradle looks like

`apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.nsks.nsksappwithreact"
minSdkVersion 19
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
ndk { abiFilters 'armeabi-v7a', 'x86' }
}
packagingOptions {
pickFirst 'lib/x86_64/libjsc.so'
pickFirst 'lib/arm64-v8a/libjsc.so'
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
// buildToolsVersion '28.0.3'
}

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'

    implementation "com.facebook.react:react-native:+" // From node_modules
implementation 'com.android.support:preference-v7:28.0.0'

}`
