ReactNative 0.59.8 project – unable to archive for for iOS while app store release & Validate Buttons is always grayed out

, , , , 0 Comments

Recently we faced a very strange issue while releasing our ReactNative App to Apple App Store. We were unable to submit the app to iOS app store because we were failing to generate iOS Archive. XCode always generating Generic XCode Archive rather than iOS App Archive.

Since XCode was generating Generic XCode Archive, Validate button was always disabled ( grayed out). We were failing to proceed further to submit the app. After exploring the issue we came across an apple help page which was suggesting following fixes to be done for our app.

  1. Your archive contains header files.

If your app links against a static library, then your archive contains header files because the library probably uses a Headers build phase to export these files as shown in Figure 4. Headers build phases do not work correctly with static library targets when archiving in Xcode. Delete this phase, add a Copy Files build phase to your library, and use it to export your header files. See Copying Files While Building a Product for more information about adding a Copy File build phase to your project.

 2. Your archive contains static libraries or frameworks.

You must set “Skip Install” to YES to prevent your static libraries or framework from being added to your archive.

the second step was little easy , however the first step was a big headache, a react native app will be having lot of static libraries, in that changing all header build phase to copy files build phase is a big manual work and we will get lot of compilation errors like Redenition of MethodDescriptor in NativeModule.h kind of.

Errors we see after moving header files from headers build phase to copy files build phase

You can see a stackoverflow question on this : xcode is creating generic xcode archive instead of iOS App Archive -> SO-Question

Solution:

How to release iOS app to app store when archive is troubling in XCode v11.x.x

if you are using XCode v11.x then apple has removed Application Loader from XCode Developer tools. Now the alternative to that is Apple’s Transporter Application

Again the steps are same as given below to submit your app to app store,

Essentially, after you do the Clean Build Folder, and then Build, you find the .app file in: ~/Library/Developer/Xcode/DerivedData//Build/Products/Release-iphoneos/

Create a new folder on your desktop named Payload (this name is case-sensitive)

Copy your .app file and paste the copy in this Payload folder.

Right click the folder and choose “Compress Payload”

When you save this, do not save it with the .zip extension, but instead save it with a .ipa extension.

This is now your .ipa file for your app, and you can upload this through Xcode Transporter App

How to release iOS app to app store when archive is troubling in XCode v10.x.x

We have to follow different approach to release the app.

There is another way to upload your app build to the app store: by creating an .ipa file of your app, and uploading it through Application Loader in Xcode ( just click cmd + space in your mac machine and search Application Loader ).

I don’t remember all the resources I found that helped me figure this out, but this was one of them: How to build .ipa application for react-native-ios?

Essentially, after you do the Clean Build Folder, and then Build, you find the .app file in: ~/Library/Developer/Xcode/DerivedData//Build/Products/Release-iphoneos/

Create a new folder on your desktop named Payload (this name is case-sensitive)

Copy your .app file and paste the copy in this Payload folder.

Right click the folder and choose “Compress Payload”

When you save this, do not save it with the .zip extension, but instead save it with a .ipa extension.

This is now your .ipa file for your app, and you can upload this through Xcode Application Loader.

    NOTE: Application loader asks for app specific password , kindly refer to generate app specific password -> https://www.imore.com/how-generate-app-specific-passwords-iphone-ipad-mac

The upload process will tell you if there is anything wrong with your build, but if there is not, it will upload to the app store and you should be able to find it in App Store Connect in a few moments.

Hope this helps you and/or others!

React Native Crash Undefined is not an object (Evaluating ‘Sn[e]’)

Any one facing react native build issue? I am trying to generate debug build but its crashing when the app is launched . The exception has no useful information. I was facing the same issue with

sudo react-native run-android

 

But that got resolved after upgrading RN from 0.48 to 0.55(latest Stable Version). But the crash remain same for the apk generated using

sudo gradlew assembleDebug

The crash is similar to https://github.com/facebook/react-native/issues/16745

please see screenshot

Solution: Generating React Native Android Release and Debug Builds

1. If any one facing issue with generating ReactNative android build then do not forget to follow below steps

2. Update your key store details as given here

3. Then explicitly bundle the assets using below command

react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

4. Generate the build using gradle

cd android && ./gradlew assembleRelease

Note: for release build I am facing another issue as follows

Error in Release build :

FAILURE: Build failed with an exception.

* What went wrong:
Failed to capture snapshot of input files for task ‘bundleReleaseJsAndAssets’ property ‘$1’ during up-to-date check.
> Failed to create MD5 hash for file ‘/Development/SourceCode/MobApp/testApp/root-state/sock’.

* Try:
Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output.

* Get more help at https://help.gradle.org

BUILD FAILED in 2s

1. If you are using react-navigation version “1.0.0-beta.11” then kindly use the below code to reset navigation stack

const resetAction = NavigationActions.reset({
    index: 0,
    key: null,
    actions: [ NavigationActions.navigate({ routeName: 'Home' }) ],
  });
  navigation.dispatch(resetAction);

//Note key: null is very important here.

React Native react-navigation performance issue: Optimising performance

Rather than writing a detailed article here, I would like to point out very few performance tuning technique with respect to React Native Navigation using react-navigation package.

1. Few check you have to do before blaming react-navigation library, Check whether are you calling any location api to fetch current location.

If you are fetching current location on component mount or will mount then consider my suggestion , fetch the current location on launch of app and save the location, then onwards use the saved location rather than fetching current location every time.

Find the code here to do so

import { AsyncStorage } from 'react-native';

let instance = null;
class SharedPreferences {

  constructor() {
    if (!instance) {
      instance = this;
    }
    return instance;
  }
  async put(key, val) {
    try {
      await AsyncStorage.setItem(key, val);
    } catch (error) {
      console.error('Unable to save in preferences: ', error);
    }
  }

  async get(key) {
    try {
      return await AsyncStorage.getItem(key);
    } catch (error) {
      console.error('Unable to get from preferences: ', error);
    }
  }

   getMultiple(keys, callback) {
     AsyncStorage.multiGet(keys, (err, stores) => {
       if (!err) {
         const keyVals = {};
         stores.map((result, i, store) => {
           keyVals[`${result[0]}`] = result[1];
         });
         callback(keyVals);
       } else {
         callback([]);
       }
     });
  }
}

const sharedPreference = new SharedPreferences();

export const SHARED_PREFERENCE = {
  accessor: sharedPreference
};

'use strict';

import { SHARED_PREFERENCE } from './SharedPreferences';
import { SHARED_PREFERENCE_KEYS } from './AppConstants';

const defaultLocation = {
  coords: {
    latitude: 12.9833,
    longitude: 77.5833
  }
};

export function getCurrentLocation(navigator, callback) {
  SHARED_PREFERENCE.accessor.get(SHARED_PREFERENCE_KEYS.LAST_SAVED_LOCATION_ID)
  .then(savedLocation => {
    if (savedLocation !== null && savedLocation !== undefined) {
      const location = JSON.parse(savedLocation);
      console.log('Returning Saved Location');
      callback(location);
    } else {
      navigator
      .geolocation.getCurrentPosition(
        (location) => {
          console.log(`Saving Device Current Location due to failed save in last try:
             ${JSON.stringify(location)}`);
          SHARED_PREFERENCE
          .accessor
          .put(LAST_SAVED_LOCATION_ID, JSON.stringify(location));
          callback(location);
        }, (geoError) => {
          callback(defaultLocation);
        },
        { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 });
    }
  })
  .catch((locationError) => {
    callback(defaultLocation);
  });
}

export function saveCurrentLocation(navigator) {
  navigator
  .geolocation.getCurrentPosition(
    (location) => {
      console.log(`Saving Device Current Location: ${JSON.stringify(location)}`);
      SHARED_PREFERENCE
      .accessor
      .put(LAST_SAVED_LOCATION_ID, JSON.stringify(location));
    }, (geoError) => {
      console.log(`Save Location Failed. ${JSON.stringify(geoError)}`);
    },
    { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 });
}

2. Use Stateless components than ReactComponents wherever it is possible : Read more about StateLessComponents

3. Upgrade react-navigation package from “1.0.0-beta.11” to “2.0.0-rc.9” : This will boost the performance of react-navigation .

React Native Social Authentication Using Firebase: Google+ and Facebook Signin, Signup – A Step by Step Guide

React Native Social Authentication Using Firebase: Google+ and Facebook Signin, Signup – A Step by Step Guide

One has to go through following steps to enable social authentication in their react native mobile apps. In this tutorial we will see how to enable react native social login for android applications.

React Native Google Plus Signup/Signin Using Firebase Authentication

1. Create Project in Google Cloud Platform : Try free trail 

2. Enable Google+ API for your project and generate API Key

GCloudApiKey1

GCloudApiKey1

3. Set YourSHA-1 key and package name (as given in AndroidManifest.xml ) of your android project

To generate your own SHA-1 use the command -> keytool -list -v -keystore mystore.keystore

NOTE : If Your build is debug build then theSHA-1 generated with above command won’t work, kindly check your adb logs carefully, theSHA-1 being used by your android debug build will be logged in the device log. To check device log run the below command from your /Users/<YourSystemUserName>/Library/Android/sdk/platform-tools —> adb logcat

APIKey&SHA1

APIKey&SHA1

4. Import the same project in firebase

ImportProjectFirebase

ImportProjectFirebase

5. Setup android project in your firebase project, then setup authentication methods being used in your app.

firebaseAuthMethods

firebaseAuthMethods

6. Then setup sameSHA-1 Key for your firebase project: Navigate to Project setting from side bar and click on general , select android app and set SHA-1 key

NOTE: Once SHA-1 is setup, download google-services.json file in the same page. and keep the file under your android project director app folder /ReactNativeProjectFolder/android/app

Till this your google cloud and firebase setup is done, now we have to do lot of changes in code.

7. add ‘react-native-google-signin’ and ‘firebase’ modules

npm install react-native-google-signin –save

npm install firebase –save

8. Add dependency in your /app/bundle.gradle

Note : in below code those excludes are most important, or else you will encounter strange linking errors.

implementation project(':react-native-google-signin')

if your app is using some other dependencies like react-native-maps or react-native-social-share then do below changes as well

implementation(project(":react-native-google-signin")){
    exclude group: "com.google.android.gms" // very important
}
compile(project(':react-native-maps')) {
      exclude group: 'com.google.android.gms', module: 'play-services-base'
      exclude group: 'com.google.android.gms', module: 'play-services-maps'
    }
implementation 'com.google.android.gms:play-services-base:11.+'
implementation 'com.google.android.gms:play-services-maps:11.+'

9. your android/bundle.gradle file should look as follows

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:3.0.0' // &lt;--- add this
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
}

ext {
    compileSdkVersion   = 23
    targetSdkVersion    = 23
    buildToolsVersion   = "23.0.1"
    googlePlayServicesVersion = "10.2.4"
    androidMapsUtilsVersion = "0.5+"
}

 

10. run below commands

npm install

react-native link

11. Once you run react native link – check android/settings.gradle file , cross check that there should not be duplicate lines of content.

So far we have done project level configurations, now let us see code changes

12. React Native Google sign-in/sign-up using firebase code

import { GoogleSignin } from 'react-native-google-signin';
import firebase from 'firebase';

function googleAuthConfig(successCallback, failureCallback) {
  /*
   Web Client id 
      Get the client_id from Google-services.json file, in that file under 
    "client": [
       "oauth_client": [
        {
          "client_id": "", //This you have to use as webClientId and the same for android
          "client_type": 3
        }
       
  */
  GoogleSignin.configure({
    iosClientId: CLIENT_IDS.GOOGLE_IOS_CLIENT_ID,
    webClientId: '',
    hostedDomain: '', // specifies a hosted domain restriction
    forceConsentPrompt: true, // [Android] if you want to show the authorization prompt at each login
    accountName: '' // [Android] specifies an account name on the device that should be used
  })
  .then(() =&gt; {
    console.log('Google Config Success');
    successCallback();
  })
  .catch((err) =&gt; {
    console.log('Google Config Error');
    failureCallback(err);
  });
}


function googleSignin() {
  googleAuthConfig(() =&gt; {
      GoogleSignin.signIn()
      .then((user) =&gt; {
        const { accessToken } = user;
          var credentials = firebase.auth.GoogleAuthProvider.credential(null, accessToken);
          firebase.auth().signInWithCredential(credentials)
          .then((firebaseResult) =&gt; {
            loginToSG(dispatch, firebaseResult, props, 'Google', registerCallback);
          })
          .catch(error =&gt; console.log('error while checking with firebase', error));
      })
      .catch((err) =&gt; {
        console.log(err);
        });
    }, (googleConfigErr) =&gt; {
        console.log(googleConfigErr);
    });
}

13. Finally the most important step is -> once do npm cache clean, delete your existing app from device, delete build folders then run the app 

react-native run-android

React Native: Ejecting Expo To Regular React Native Project.

Before explaining the steps for eject from expo, I would like to thank the expo community who has done really a great job, it was nightmare for us to start with ReactNative initially without expo. Expo has done remarkable job and simplified the whole process to us. So we should thank expo community for that. But Expo has come up with its own limitations, it is really difficult to go forward with those limitations, hence ejecting from expo is must.

Follow below steps and find the issues listed in each step and the solutions for the issues faced during eject process. Follow all the below steps

1. npm run eject

<span style="color: #000000;">? How would you like to eject from create-react-native-app? (Use arrow keys)
❯ React Native: I'd like a regular React Native project. 
  ExpoKit: I'll create or log in with an Expo account to use React Native and the Expo SDK. 
  Cancel: I'll continue with my current project structure. 
Choose 1st option</span>

2. then run the command

react-native run-android
Building and installing the app on the device (cd android && ./gradlew installDebug)…

Problem:

* What went wrong:
A problem occurred configuring project ‘:app’.
> SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

* Try:

Solution:
Create local.properties in the andoid project folder and save the below content in that
sdk.dir = /Users/USERNAME/Library/Android/sdk
USERNAME: USERNAME should be your maachine user name

3. run the command

$ sudo react-native run-android

   Solution : Use proper cable and connect your device, enable debug mode in your android device. this is problem with some devices, do not spend time on this, because you will face bigger problems later 🙂 so either change the device or try with different cable.

React Native Building In Android and iOS: After Ejecting(Detaching) Expo with ExpoKit

React Native Building In Android and iOS: After Ejecting(Detaching) Expo

I am trying to build React Native app for android and iOS but keep finding one and other issues. After so much struggle I succeeded with initial hickups but now struck at one point where I am not finding any solution.

Problems I am facing with React Native Build For Android and iOS , before encountering the issue I followed the below steps

1. Install Cocoapods (https://cocoapods.org/)
2. Run pod install from your project’s ios directory.
3. Run ‘react-native run-ios’ in the project root folder.
4. Run ‘react-native run-android’ in the project root folder.

After running react-native run-android I am getting below error.

:app:transformClassesWithJarMergingForDebug 
FAILED

FAILURE: Build failed with an exception.

* What went wrong:

Execution failed for task ':app:transformClassesWithJarMergingForDebug'.

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/auth/api/signin/zzc.class
* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 25.103 secs

Could not install the app on the device, read the error above for details.

Make sure you have an Android emulator running or a device connected and have

set up your Android development environment:

My app gradle file looks as follows

<span style="color: #3366ff;">apply plugin: 'com.android.application'

  }

</span>

 

Solution:

The solution is to find the conflicting dependencies using following command inside your app/android folder

$ ./gradlew app:dependencies

Closely observe the dependency hierarchy and check the conflicted dependency for com.google.android.gms. To resolve this you have to exclude it for specific dependency as follows, see the updated build.gradle file

apply plugin: 'com.android.application'

android {
  compileSdkVersion 26
  buildToolsVersion '26.0.1'

  defaultConfig {
    applicationId "com.mycompany.testapp"
    minSdkVersion 19
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
    ndk {
      abiFilters 'armeabi-v7a', 'x86'
    }
    manifestPlaceholders = [
      'appAuthRedirectScheme': 'com.mycompany.testapp'
    ]
  }
  buildTypes {
    release {
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
  dexOptions {
    javaMaxHeapSize "8g"
  }
}

task exponentPrebuildStep(type: Exec) {
  workingDir '../../'

  if (System.getProperty('os.name').toLowerCase().contains('windows')) {
    commandLine 'cmd', '/c', '.\\.expo-source\\android\\detach-scripts\\prepare-detached-build.bat'
  } else {
    commandLine './.expo-source/android/detach-scripts/prepare-detached-build.sh'
  }
}
preBuild.dependsOn exponentPrebuildStep

repositories{
  flatDir{
    dirs 'libs'
  }
  mavenLocal()
  maven { url 'https://maven.fabric.io/public' }
}

  compile "com.facebook.react:react-native:+"  // From node_modules
  compile ("com.google.android.gms:play-services-base:10.0.1") {
      force = true;
  }
  compile ("com.google.android.gms:play-services-maps:10.0.1") {
