How to detect a phone call in Android phone with React Native?

$
0
0

I'm building an app and I need to detect all phone calls, assuming my app is always in the background.

I've looked over react-native-call-detection package from https://www.npmjs.com/package/react-native-call-detection.

The question is, how do I make the listener global, meaning that it doesn't matter in which screen the user is or if the app is in background, how to detect incoming calls?


Network Error when use axios in React Native

$
0
0

This is long-standing problem for me and I can't find solution at all.

Within my react native project(react-native-cli), I send request to server using axios package. But when I'm testing with my android phone, it gives [Error: Network Error]. With emulator, it's okay.

I'm sure this is not back-end problem because I've tested with several servers. And I also used fetch instead but got same error.

Here is version information.

"axios": "^0.19.0",
"react": "16.9.0",
"react-native": "0.61.5",

Sometimes, it's working on android phone too. This problem is biggest mystery and I suffered for a long time.

Somebody who experienced this issue, please alive me. Thank you for careful reading.

Sometimes, it's not working even with android emulator. But after deleted original emulator and created new emulator, it's working.

Keeping logic in js on foreground services in React Native, some downsides?

$
0
0

TLDR;

I'm keeping all (handle logic and store state) in js in my music player app and this works even when app is closed/killed if we registered it properly as a foreground service.

What I was trying to do

I was playing making a music app with the next features:

  • track queue

  • auto play next song

  • play/pause/stop

  • play when app is closed

  • control the app with a persistent notification

What I did

I found a lib that could do the whole work exact as I needed... but it was too buggy. So, should I write all that code in a Java/Swift native module? before giving me up I looked in Android docs about process and services and I found that the app and service code runs in the same main thread, so all I need is a service attached to a notification and my app bounded to that service in order to prevent be killed when app closes. Based on this, we can keep all our logic (skip to next song, etc) and state (track queue) in js and use native code just to play music and handle interactions with the notification calling the js code to handle it. But, before trying that, I wanted to try some native libs to handle the audio player and the notification.

  • react-native-sound

  • react-native-music-control

Results

As react-native-music-control uses startForeground(NOTIFICATION_ID, notification); our app is already safe of system clean up. I tried this and indeed it worked as expected. I tried simulating memory warning and it still working and skipping songs perfectly. I "killed" the app from apps menu and it still works as expected.

But what about iOS? I don't know much about this one but as iOS is "inspired" on unix system too, it just worked as expected. Here it worked as a music foreground service because we have to say that in Info.plist

Questions

  • Is this enough to consider it a good production practice at least in this context (music app)?

  • Am I missing something that could be a problem in the future?

Bluetooth tests with React-Native

Im trying to use bluetooth (to connect a vibration sensor to the app) on a react-native application. I tried using react-native-ble-plx but I have a problem: when I emulate an Android Device with AVD Manager from Android Studio, how is bluetooth suppose to work? Does my PC bluetooth transmit informations to the emulated device?

TypeError: Network request failed only on POST method [closed]

I am trying to fetch POST in React Native for a Node server that I made myself. When I make a POST attempt, it returns "[TypeError: Network request failed]", but when I make a GET attempt it executes it. I already tested it on PostMan and everything happens correctly. I'm using AVD (Android Emulator)

REACT NATIVE:

    _updateInfos = () => {
    var myHeaders = new Headers();
    myHeaders.append("Content-Type", "application/x-www-form-urlencoded");
    myHeaders.append("x-access-token", this.props.cookie);

    const body = new FormData();

    body.append("postid", this.state.shop.id);
    body.append("whatsapp", this.state.whatsapp);
    body.append("telefone", this.state.telefone);

    var links = [{
        network: {
            Instagram: {
                url: "https://instagram.com/" + this.state.instagram + "/",
            },
            Facebook: {
                url: "https://facebook.com/" + this.state.facebook + "/",
            }
        }
    }]

    var toApi = Serialize.serialize(links);

    body.append("links", toApi);

    var requestOptions = {
    method: 'POST',
    headers: myHeaders,
    body: body,
    redirect: 'follow'
    };

    fetch("http://api.parquedasfeiras.online/api/uploads", requestOptions)
    .then(response => response.text())
    .then(result => {
        console.log(result);
    })
    .catch(error => {
        console.log(error);
    });

NODEJS:

app.post('/api/updateinfos', function (req, res) {
  var postId = req.body.postid;

  var whatapp = req.body.whatsapp;
  var telefone = req.body.telefone;

  var links = req.body.links;

  console.log(postId);
  console.log(whatapp);
  console.log(telefone);
  console.log(links);

  res.send("hey")
});

Android App Bundle from React Native: You uploaded an APK or Android App Bundle with invalid or missing signing information for some of its files

$

I'm trying to publish an app for the first time to the Google Play Store. I've opted in to Google Play Signing. I know for a fact that I'm signing the Android App Bundle with the right key since, when I'm uploading using another key, the Console will tell me to upload using the other key with the specific SHA1 identifier. However, when I do upload with the correct key, I get this error:

You uploaded an APK or Android App Bundle with invalid or missing signing information for some of its files.

I'm building the app using Android Studio like so: Build > Generate Signed Bundle / APK > Android App Bundle > Choosing my keystore and entering the password > release > Finish

The app is a React Native app built with detached Expo / ExpoKit. Uploading to the Apple App Store works just fine, I only have problems with the Play Store. What am I missing?

Update 1: I now completely deleted the app from Google Play and created a new one. Did not opt in for Google Play Signing this time and uploaded a signed APK. Still the same error.

Update 2: Tried with a completely new keystore and key. Still the same.

What is the equivalent of 'SafeAreaView' on android - React Native

$
0
0

Basically, i am creating a react-native app and i wanted that my logo image didn't overlap with the notification/status bar and i didn't want to set a marginTop property manually because the size of the notification bar changes on different models of phones, and i found out that if i replaced my <View/> component with a <SafeAreaView/> component my problem would be solved.

And while it worked great for IOS, it didn't worked at all for android. Of course, after a quick research i found out that this is a IOS only component, and when you try to use it on Android the <SafeAreaView/> component returns a regular <View/> back.

So, i am trying to find out if there's a component or a workaround that works on android.

React native - compile bundle with android studio

The text of button at react native is always uppercase

$

0

I created a component at react-native, but the text of the button is always at uppercase, someone knows why it doesn't take the text that pass, because I want to show 'Login', but it shows 'LOGIN'

import React, { Component } from 'react';
import { View, Button} from 'react-native';
import LabelApp from "../../config/labels.app";

const labelApp = LabelApp.loginView;

export default class Login extends Component {

  constructor(props){
    super(props);
    this.handleClickBtnEnter = this.makeLogin.bind(this);
  }

  makeLogin() {

  }

  render() {
    return (
     <View>
       <Button title= {labelApp.textButtonLogin} onPress={this.handleClickBtnEnter}/>
     </View>
    );
  }
}

Label of component

const LabelApp = {
    loginView: {
        textButtonLogin: 'Ingresar',
    },
}
export default LabelApp;

> Failed to parse React Native CLI configuration. Expected running 'npx --quiet --no-install react-native config' command from '/Users/yashatreya/Desktop/Realyze/Realyze' directory to output valid JSON, but it didn't.

React-Native Android ReactContext returning null

$
0
0

As the React-Native AppState API is iOS only I'm writing an appState event emitter for the Android side of my app. In the app's MainActivity on the Java side, I want to emit from the onResume and onPause functions to tell the JS side over the bridge that my app is either in the foreground or background

At the moment, I can minimise my app (and go back to the home-screen on my device) and the background event is emitted correctly. However, when I resume my app nothing is fired...also nothing is fired when the app initially opens up.

I've narrowed this down to the fact that in these cases mReactInstanceManager.getCurrentReactContext() is null...for some reason.

Here's my code from MainActivity.java:

@Override
protected void onPause() {
    super.onPause();

    if (mReactInstanceManager != null) {
        mReactInstanceManager.onPause();

        //send the appState back to JS
        Log.d("REACT_STATE", "Paused");  //this always fires
        if(mReactInstanceManager.getCurrentReactContext()!=null) {
            WritableMap params = Arguments.createMap();
            params.putString("currentAppState", "background");
            sendEvent(mReactInstanceManager.getCurrentReactContext(), "appStateChange", params);
        }
    }
}

and,

@Override
protected void onResume() {
    super.onResume();

    if (mReactInstanceManager != null) {
        mReactInstanceManager.onResume(this, this);

        //send the appState back to JS
        Log.d("REACT_STATE", "Resumed"); //this also always fires
        if(mReactInstanceManager.getCurrentReactContext()!=null) {
            WritableMap params = Arguments.createMap();
            params.putString("currentAppState", "foreground");
            sendEvent(mReactInstanceManager.getCurrentReactContext(), "appStateChange", params);
        }
    }
}

and this is the emitter code:

private void sendEvent(ReactContext reactContext,
                       String eventName,
                       @Nullable WritableMap params) {
    reactContext
            .getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
            .emit(eventName, params);
}

The JS side of things is set up OK and working - I can provide this code if it helps. I'm fairly certain my issue lies on this side. Am I trying to emit this at the wrong time? Do I need to move it elsewhere? Any advice is much appreciated!

React Native Mobile Apps Documentation Tools

I built a React Native project and trying to make a Documentation of it with some 3rd party tools. Is there any appplication that will help you to make Documentation of React Native project?

I have a few in mind like :

  • Espresso from Android Studio

  • Appium (but I think this is for mobile automation. CMIIW)

I need an app that help me to capture the screen of the mobile apps, list its process (input, output, button click, etc), and export its result as a .txt or whatever format that easy to copy to MS Word for better formatting.

Hi I made a Flutter webview app but the notification of cookies (first image) does not hide when I injected this code:

(await _controller.future).evaluateJavascript("document.getElementById('st_notification_1')[0].style.display='none';");

enter image description here

The code of one of my pages which I should Inject the two code is this:

import 'dart:async';
import 'dart:math';
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';

class HomePage extends StatefulWidget {
  HomePage({Key key}) : super(key: key);

  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {

  WebViewController _myController;
      final Completer<WebViewController> _controller =
      Completer<WebViewController>();
  @override
  Widget build(BuildContext context) {
    return SafeArea(
            child: Scaffold(
                  body: WebView(
                  initialUrl: 'https://syncshop.online/en/',
                  javascriptMode: JavascriptMode.unrestricted,
                  onWebViewCreated: (controller) {
                  _controller.complete(controller);
                },
          onPageFinished: (controller) async {
          (await _controller.future).evaluateJavascript("document.getElementsByClassName('footer-container')[0].style.display='none';"); //THIS ONE WORKS 
          (await _controller.future).evaluateJavascript("document.getElementById('st_notification_1')[0].style.display='none';");
          (await _controller.future).evaluateJavascript("document.getElementById('sidebar_box')[0].style.display='none';");
          },
          ),
    floatingActionButton: FutureBuilder<WebViewController>(
        future: _controller.future,
        builder: (BuildContext context, AsyncSnapshot<WebViewController> controller) {
          if (controller.hasData) {
            return FloatingActionButton(
            onPressed: () {
              controller.data.reload();
            },
            child: Icon(Icons.refresh),
          );
          }
          return Container();
        }
        ),
          ),
      );

how to use 2 react-native packages with same class names/ namespaces

$

I have a react-native app with react-native-purchases and react-native-indicative packages. They both have imports like

import com.reactlibrary.RNPurchasesPackage;

import com.reactlibrary.RNIndicativePackage;

in MainApplication.java

As they have same namespace or classnames, I am facing the below error. Is there a way to resolve this namespace conflict without modifying the package namespaces ?

I want to do something like as shown in the image below but I don't have any idea how to achieve that (I googled it, but I found only result for native code Swift, Obj C, ...).

enter image description here

Do I have to play with some layers or something like that?

Thanks for your answers!

I want 4 images to be proportionally displayed on screen and I am really bad with CSS generally, so I can't figure out here how to do it. I was trying with flex, to set it on 1 and then on sub-views to set it on 0.25, but it doesn't work, even tried flexWrap, still nothing, it's always in one row, as I set flexDirection to be row

<View style={getStyle(styles, ["container"], this.props.theme)}>
    <View style={styles.itemContainer}>
      <TouchableHighlight
        onPress={() => this.onHandlePress("DevicesNavigator")}
      >
        <Icon name="pencil" color="yellow" size={100} />
      </TouchableHighlight>
      <Text style={styles.imageText}>
        {strings("initialTab.devicesTab")}
      </Text>
    </View>
    <View style={styles.itemContainer}>
      <TouchableHighlight
        onPress={() => this.onHandlePress("ReportsNavigatior")}
      >
        <Icon name="tablet" color="yellow" size={100} />
      </TouchableHighlight>
      <Text style={styles.imageText}>{strings("initialTab.reports")}</Text>
    </View>
    <View style={styles.itemContainer}>
      <TouchableHighlight
        onPress={() => this.onHandlePress("SyncNavigatior")}
      >
        <Icon name="refresh" color="yellow" size={100} />
      </TouchableHighlight>
      <Text style={styles.imageText}>{strings("initialTab.sync")}</Text>
    </View>
    <View style={styles.itemContainer}>
      <TouchableHighlight
        onPress={() => this.onHandlePress("SettingsNavigatior")}
      >
        <Icon name="gear" color="yellow" size={100} />
      </TouchableHighlight>
      <Text style={styles.imageText}>{strings("initialTab.settings")}</Text>
    </View>
  </View>

And style:

  container: {
    flex: 1,
    justifyContent: "center",
    alignContent: "center",
    flexDirection: "row"
  },
  containerLIGHT_THEME: {
    backgroundColor: colors.initialFourScreenBackgroundColorLight
  },
  containerDARK_THEME: {
    backgroundColor: colors.initialFourScreenBackgroundColorDark
  },
  itemContainer: {
    flex: 0.25
  },
  imageText: {
    color: "green"
  }
});
