Android application keeps stopping . Does not work react-native-navigation on Android

[sinevitch]

Issue Description

Does not work react-native-navigation on Android
Starting : Intent { …MainActivity }.

Did everything as indicated in the documentation. I launch the Android Studio emulator.

On iOS, the same code works fine
index.ios.js
import App from './App';

index.android.js
import App from './App';

app.js:

   import { Navigation } from "react-native-navigation";
   import AuthScreen from "./src/screens/Auth/Auth";
   // Register Screens
   Navigation.registerComponent("awesome-places.AuthScreen", () => AuthScreen);

   // Start a App
     
   Navigation.startSingleScreenApp({
              screen: {
               screen: "awesome-places.AuthScreen",
               title: "Login"
            }
    });

auth.js:

import React, { Component } from 'react';
import { View, Text } from 'react-native';

class AuthScreen extends Component {
    render () {
        return (
            <View>
                <Text>Auth Screen</Text>
            </View>
        );
    }
}
export default AuthScreen;

     @Override
     public boolean isDebug() {
         // Make sure you are using BuildConfig from your own application
         return BuildConfig.DEBUG;
     }

     protected List<ReactPackage> getPackages() {
         // Add additional packages you require here
         // No need to add RnnPackage and MainReactPackage
         return Arrays.<ReactPackage>asList(
             new VectorIconsPackage()
         );
     }

     @Override
     public List<ReactPackage> createAdditionalReactPackages() {
         return getPackages();
     }
 }

I tried to use the version of "react-native": "^ 0.49.5",
The same thing happens
Android does not work
IOS works

• Android Studio version 3.1

[peakyDicers]

I am having a very similar issue. My project builds successfully, but a blank screen appears in the android emulator, and the developers menu cannot be accessed. I've posted my setup and screenshots in this similar thread. #2687

[chinmaygit]

Try this,
stop the packager.
adb reverse tcp:8081 tcp:8081
start the packager.

[sinevitch]

adb reverse tcp:8081 tcp:8081

Did not help

[chinmaygit]

@sinevitch Open Logcat while you are opening the app, and look for crash log and share it here.

[sinevitch]

[AmaruNozomi]

Same here :
Starting: Intent { cmp=com.XXX/.MainActivity }

and

"Unfortunately, Application has stopped" message on the emulator

trying adb logcat in terminal but can't locate the error source !!

any updates on the issue?

[ghost]

Facing the same issue. any fix?

[ashifa454]

Any update on this issue?

[ghost]

In android, changed react-native dependeny to
compile('com.facebook.react:react-native:0.51.1') { force = true }

Version should be exact same as in package.json
Cleaned and rebuilt project and it worked.

[SirPhemmiey]

Any update on this issue?

[guyca]

The single crash log which was posted here has nothing to do with RNN. I'm closing as we really can't help you resolve this issue.

[NySiya]

I am having this very same problem :(

[MaciekLeks]

The same issue after linking with react-native-firebase. No logs. It's just crashing on the physical device.

[wijaksanapanji]

The same issue after linking with react-native-firebase. No logs. It's just crashing on the physical device.

any solution for your problem, im new to react-native, i got the same problem after adding react-native-firebase

[MaciekLeks]

I've got it. The problems lies in the android/app/build.gradle dependency versions. Try to put there all the new one version numbers looking at (in this case for Android):

• firebase libs

• google play services

Then, the immediate shutting down should no longer appears. Then you probably see other exceptions but just follow any other tips.

[wijaksanapanji]

The same issue after linking with react-native-firebase. No logs. It's just crashing on the physical device.

any solution for your problem, im new to react-native, i got the same problem after adding react-native-firebase

i just moved google() in android/build.gradle to the top, and it worked

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

[marcosgallardo]

@sinevitch

Try by changing your MainActivity.java to:

package com.rncourse; //<- App package name goes here

import com.reactnativenavigation.controllers.SplashActivity;

public class MainActivity extends SplashActivity {

}

[potatokoosh]

Corriendo un app con react-native
tube el mismo problema, me estuvo saliendo el mensaje de App keep stopping, el emulador no me mostraba la app,, lo solucione con los siguientes pasos

1. abrir el proyecto en android studio
2. ejecutar el play o el emulador (aqui no me abre el proyecto sale app keep stopping)
3. desde la terminal das react-native run-android

espero ayude

[potatokoosh]

adb reverse tcp:8081 tcp:8081

Did not help

try to run from terminal, react-native run-android
but first you have to have open android studio with the project and runing a emulator,, probably the message will apear (app keep stopping),,then in terminal you run react-native run android

this worked for me

i hope it works for you

[mohshbool]

@potatokoosh It also didn't work for me, but my message is "myApp keeps stopping". Does anybody have any other solutions?

[monaye]

having the same error message for the Android release build.
"react": "16.6.3",
"react-native": "0.58.6",

Are there any tools to debug what is going on in the release build?

[ThatoMahlatji]

In my case the application loads when the phone is connected to the metro-builder, but once the phone is disconnect from the Metro-builder the application crashes.

[AntonioMIN]

I had the same problem. But I just fixed it by pressing Ctrl + M a few times. I do not know how it works.

[naveenfy]

I have the same problem. :|

[naveenfy]

I closed the app and relaunched it from the Android, it worked for me.

[AmeraAbdallah]

I had a similar problem, I fixed it by removing component from screen that I wanna navigate to it, and it was nativeBase Picker component

[maxjf1]

I had this problem with the lib react-native-pdf-lib.

With LogCat i figure it out, i had to ask for WRITE_EXTERNAL_STORAGE with PermissionsAndroid

[jgo80]

Occurred to me as well, just like this without adding packages.
I was trying to find a solution, reading a lot, without luck.
I finally desperately wiped the Android Emulator and - tataaa - that was it. Worked for me.

[EdersonJunior]

I solved this issue (in my case) using this link: https://medium.com/@impaachu/react-native-android-release-build-crash-on-device-14f2c9eacf18.

[gorvinsky]

I solved this issue (in my case) using this link: https://medium.com/@impaachu/react-native-android-release-build-crash-on-device-14f2c9eacf18.

It seems that there could be different reasons for this to happen and the best way to nail the cause is by using this method. I solved mine with this and for my case, it's because of a library that I installed. I solved it by uninstalling that library.

[raemarcsg30]

Maybe you don't have index.android.js and index.ios.js with import App from './App'; ?

[diebraga]

I could not solve the problem but you can just '' react-native init '' and change app.js from the the old app.

[arthedza]

Maybe you should restart Metro bundler

[pedromelo98]

same here
"react": "16.8.3",
"react-native": "^0.60.4"
AndroidX

[rajnishcoder]

I could not solve the problem but you can just '' react-native init '' and change app.js from the the old app.

Does that solved the problem?

[PrateekOraon]

See that you don't have two react-native versions installed simultaneously. Do :
npm list --depth

If there are two RN versions, there will be a version mismatch and the app will keep stopping.

npm uninstall react-native@<the-version-you-want-to-uninstall>
Then run your code again.

[shahnawazhussain125]

build has been complete and emiulator is working then error "Keeps Stoping"

install
npm list --depth

check error and my be install
npm install eslint
my error remove run project

[yelinag]

Debug/run the project in android studio where you will be able to see error logs. For my case, there are a lot of issues as haven't tested in android for a very long time.

[ALashchotka]

Works for me: evollu/react-native-fcm#998 (comment)

[marcinkieruzel]

In my case gradlew clean on Windows or ./gradle clean on Linux makes the emulator works again.

[ghost]

how can i remove this error..

[MartykQ]

For me the problem was I was following steps from react-native docs instead react-navigation official docs. The first one does not mention this step:

---

To finalize installation of react-native-screens for Android, add the following two lines to dependencies section in android/app/build.gradle:

implementation 'androidx.appcompat:appcompat:1.1.0-rc01'
implementation 'androidx.swiperefreshlayout:swiperefreshlayout:1.1.0-alpha02'

[PontesVinicius]

I solved this error by updating the version of Android Studio.

[robauer]

I solved this error by updating the version of Android Studio.

Updating is what go me into this mess.

[Cmion]

gradlew clean, uninstalling the app then yarn run android solved the problem on windows

[iankressin]

@Cmion answer works in Ubuntu 20.4 as well

[WadhahEssam]

what solved it for me was cleaning the project, so it might work for you.
run
git clean -d -x -f

then just run
npm install or yarn

[YDaskaloff]

Assuming environment is set up correctly and you are not using Expo, run the following:

~ cd android
~ ./gradlew clean
~ cd ..
~ npm install
~ npm react-native start
~ npm react-native run-android

This worked for me.

I only met this problem on android 8 but it worked on android 7, 8.1 ,9 and 10

[TomHessburg]

Just got through this issue after a solid day or two of smacking my face against the wall with it lol. Not sure if this will help anyone, but this was the issue for me:

After ejecting from expo, src/main/java/.../MainActivity.java and MainApplication.java were not generated. For whatever reason, I was still able to run on android using 'expo start' even with this being that case.

When running react-native run-android, I found that first issue (got a bunch of errors saying that there was no MainApplication file). Not a problem, just went ahead and added my own.

After adding my own, I started seeing the issue that this thread is mentioning. I tried a bunch of stuff, but what ended up being the case for me was that the getMainComponentName method inside of MainActivity.java was incorrect (think it was my package name or something, where it was supposed to be "main", at least in my case).

Again, not saying this will be the issue for everyone, but might be worth it to take a look at your src/main/java//... files to see if anything looks off. To figure out what these files are supposed to look like, i just checked out some other projects (for instance the expo bare project templates repo) for reference.

If you're able to run logcat, that'll definitely help, but in my case I don't think the app was even being mounted, thus logcat wasn't showing any errors, so I had to brute force it haha.

[EshaZaheer]

i was facing he same issue but when I uninstall the app and run it again on my phone then it worked properly

[ronaldmgdev]

I solved it by deleting the node_modules and then re run

[Robogeek95]

I solved it by deleting the node_modules and then re run

Thanks @mutabazigakuba This worked for me

[engsan710]

My problem was that one of my styles had the following:
...
padding: '16px',
...
It worked just fine on the web, but the emulator did not like it. The way I found the root cause is I removed all sections until the app started. Then I add one section at a time until I found the one that had the incorrect style.
The correction was to change it to:
...
padding: 16,
...
I hope this helps somebody.

[kyrieLiu3]

gradlew clean, uninstalling the app then yarn run android solved the problem on windows

It works for me thanks to @iankressin. Actually there is always dependence issues when you install new dependence, so you just clean the cache and restart it. GOOD LUCK!

[piyushrajput45]

It works for me
Add this

android:usesCleartextTraffic="true"

in ./android/app/src/main/AndroidManifest.xml add

[gokulanand-selvan]

I'm learning react native for 1week so,i'm sharing my error fix, in my case i debugged and i cleared the things one by one that i added . Atlast there is an svg and i removed the svg, after that the app started to work fine. then i found some libraries to use svg images.

[Sudo-MARY]

In my issues, creating lauchscreen.xml inside layout folder

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/launch_screen" android:scaleType="centerCrop" />
</RelativeLayout>

and it worked
