I'm trying to share some content from my react-native app on facebook. The share activity opens and than close with this error response Failed to get app name.
This is my AndroidManifest.xml file
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="#string/facebook_app_id"/>
<activity
android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name" />
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
<provider
android:name="com.facebook.FacebookContentProvider"
android:authorities="com.facebook.app.FacebookContentProvider${facebook_app_id}"
android:exported="true" />
I'm using react-native 0.55.2 and react-native-fbsdk 0.7.0
I had encountered the same issue, the error message shown is not correct.

My company has a campaign which has an objective to increase te installations of its apps.
Our App was done in Xamarin.Forms 4.8.
I have read many many sites and searched for any tutorial about how to do that, but unfourtunatelly, I do not find anything. There are so many material about FB Login in Xamarin, was nothing about FB Pixel to get events in your xamarin.forms app.
I have read that there is a type of registration of those events in FB, called nocode, where the app sends some basic events to FB, without any code. You just need to install the nuget lib (Android and iOS) and configure AndroidManifest and info.plist files, with the pixel number, which is called FacebookAppId.
Below, is part of my AndroidManifest file:
...
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.AD_ID" />
<application android:label="#string/app_name" android:icon="#drawable/balao">
<uses-library android:name="org.apache.http.legacy" android:required="false" />
<provider android:name="android.support.v4.content.FileProvider" android:authorities="io.app.meusebrae.fileprovider" android:exported="false" android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="#xml/file_paths"></meta-data>
</provider>
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="#string/facebook_app_id" />
<activity android:name="com.facebook.FacebookActivity" android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation" android:label="#string/app_name" />
<activity android:name="com.facebook.CustomTabActivity" android:exported="true">
...
Below, part of my info.plist file:
...
<key>FacebookAppID</key>
<string>874......</string>
<key>FacebookDisplayName</key>
<string>Meu Sebrae</string>
...
I have the nuget libs Xamarin.Facebook.Android and Xamarin.Facebook.iOS installed.
According to some sites, it would be the only configuration needed to make it to run, but nothing is sent to FB dashboard, where I monitor the events captured.
So, please, I really need some tutorial or anybody to explain me, what I really need to do, and if I am doing anything wrong.
Thanks.

I am trying to use facebook auth in myy app with flutter.
I did all things in documentation.
also I tried to find solution here but nothing helped me ,for example this post and this post
I add this strings.xml :
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="facebook_app_id">xxxxxxxxxxx</string>
<string name="fb_login_protocol_scheme">fbxxxxxxxxxxxx</string>
<string name="facebook_client_token">xxxxxxxxxxxxxxxxx</string>
<string name="app_name">xxxx</string>
</resources>
in AndroidManifest.xml I add this :
<uses-permission android:name="android.permission.INTERNET"/> // before application
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="#string/facebook_app_id"/>
<meta-data android:name="com.facebook.sdk.ClientToken" android:value="#string/facebook_client_token"/>
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name" />
<activity
android:name="com.facebook.CustomTabActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="#string/fb_login_protocol_scheme" />
</intent-filter>
</activity>
<queries>
<provider android:authorities="com.facebook.katana.provider.PlatformProvider" />
my function :
final LoginResult result = await FacebookAuth.instance.login();
if (result.status == LoginStatus.success) {
accessToken = result.accessToken!;
isLogined = true;
final userData = await FacebookAuth.instance.getUserData();
} else {
print(result.status);
print(result.message);
}
I get this error [ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: MissingPluginException(No implementation found for method login on channel app.meedu/flutter_facebook_auth)
Usually the "No implementation" error is caused when you add a new package and do hot reload, or when the platform isn't supported. Try running the app from cold start.
If it still fails, I recommend using firebase_auth package for authentication since it supports multiple providers including Facebook.
From https://facebook.meedu.app/docs/5.x.x/android (where you can also find more relevant info):
Upon installation of this plugin, configuration is needed on Android before running the project again. If this is not done, an error of No implementation found would show because the Facebook SDK on Android would throw an Exception error if the configuration is not yet defined. This error also locks the other plugins in your project, so if the plugin is not yet needed, either remove it or comment it out from the pubspec.yaml file.
So, when you add the flutter_facebook_auth plugin, you have to add in configuration to avoid this error. This includes
in /android/app/src/main/res/values/strings.xml:
<string name="facebook_app_id">{your-app-id}</string>
<string name="facebook_client_token">YOUR_CLIENT_TOKEN</string>
in /android/app/src/main/AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET"/>
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="#string/facebook_app_id"/>
<meta-data android:name="com.facebook.sdk.ClientToken" android:value="#string/facebook_client_token"/>
for Android API 30+ also add
<manifest package="com.example.app">
<queries>
<provider android:authorities="com.facebook.katana.provider.PlatformProvider" />
</queries>
...
</manifest>
and Associate Your Package Name and Default Class with Your App in Facebook.
This got me past the error you mentioned.
I am working on a flutter project with mongoDB, there is no big deal at project I just want to SignUp user, but application works only on debug mode and with my mobile Hotspot. otherwise I just click signUp button and I wait long time, then ********** "SocketException: Connection timed out (OS Error: Connection timed out, errno = 110), address = 10.76.236.118, port = 44670". *********** this error throw. I work with real device android Samsung Galaxy A50 (SM-A505F), I don't think there's any error in the codes. Because it works when debug + specific IP(when I use my mobile hotspot).However, let me share the screenshot of the relevant parts. what are the things I don't know ,about IP or mongoDB or ....

If you work with a real device, your phone and your laptop have to be connected to the same internet. This is solution for me. Dont't forget add " "

Things to try
Make sure flutter doctor -v runs without ANY complaints
Edit android/gradle.properties and add the flag: android.bundle.enableUncompressedNativeLibs=false
Do a flutter clean command
Try creating a release build using flutter build appbundle
Test Locally / Offline
download bundletool
Generate a set of APKs from your app bundle, following this guide
Deploy the app to your connected device(s) following this Guide
Works?
Upload your bundle to Google Play using the internal test track, or the alpha or beta channels to test the bundle before releasing it in production
Instructions for doing this can be found here
Good Luck :)
Because it is not working after uploading on google play. then there might be some issue with your app signing. You can follow the steps here
I have faced issues like this when I used facebook login sdk, so I would suggest checking following:
Check if you have signed the apk/appbundle with proper release keystore
Check if you have opt in for google's automatic signing on playstore while deploying app
2.1 If yes then it will change the sha-1 value which is used in facebook app for authentication, for it to work use the one generated by google in playstore
Assuming that you publish an App Bundle (.aab file) the issue can be related to the format itself since it is not testable via IDE. E.g. when running the app in Release mode on a device .apk is created and provisioned to it, not .aab.
What I did in the past to troubleshoot .aab (also had failures only with GPlay version, local Debug and Release modes worked fine) was to use Firebase Test Lab. You can run automated monkey tests on 5 physical devices and 15 virtual devices every day free-of-charge. Just log in to Firebase Console, cretae an empty project, go to Test, upload your .aab file, select devices (it's worth also to choose different locales) and wait for completion. After that check logs in test results, you might find answers there (in my cases there was an issue with localization resources which got broken while producing .aab release package).
This option can be esier/faster than splitting .aab locally with comand line into APKs and testing on a local device.
In my experience, try to check your database(sqlite) if created. Try to replace the path and check if the database is created properly.
I added the flutter_local_notifications plugin to schedule notifications. In the debug version everything works well for both emulators and real devices.
However, when I build the app
flutter build apk --split-per-abi
and install the package on a device and run the app, when it comes to the code part that marks the notification (I supposed...) , the app crashes
How do I find out what's wrong?
I followed the plugin developers instructions and changed the manifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.explika">
<uses-permission android:name="android.permission.INTERNET" />
<!-- Tudo relacionado com as notificações -->

I found out what is causing the application to crash:
[ERROR: flutter / shell / platform / android / platform_view_android_jni.cc (39)] java.lang.AssertionError: java.lang.NoSuchFieldException: Drawable
However, this only happened in the Release version. The solution consists of customizing the ProGuard configuration file and the build.gradle file following the instructions on the plugin page.
I didn't do these steps because until then the Release version worked without problems and because I thought ProGuard configuration file would only be necessary in case want to publish on the Play Store.
