In android/app/build.gradle add implementation 'net.openid:appauth:0.8.1'

dependencies {
    //noinspection GradleDynamicVersion
    implementation 'com.facebook.react:react-native:+' 
    implementation 'net.openid:appauth:0.8.1' // add this line
    implementation 'androidx.browser:browser:1.2.0'
}

Also, i changed gradle version in android/build.gradle to 4.0.1

buildscript {
 dependencies {
        classpath("com.android.tools.build:gradle:4.0.1")  // modify this line
        classpath ('com.google.gms:google-services:4.3.3')
    }
}

This worked for me, hope it helps you

~Experiencing a similar issue after updating to React Native 0.65.1 and Android SDK 30. When calling authorize from react-native-app-auth (v5.1.1) the following error is returned…~

{"code": "browser_not_found", "message": "Error not specified.", "nativeStackAndroid": {}, "userInfo": {}}

~Going to try updating to the latest version of react-native-app-auth to see if that helps any~ 👍

Update after upgrading to v6.4.0

So in version 5.1.1 on RN65.1 and Android 30 I would just get an immediate failure when calling authorize(), but version 6.4.0 is slightly better…

I now get redirected to chrome when calling authorize() to an Okta page (we using Amazon Cognito and Okta), I can enter a username and password, but after clicking login on Okta I get redirected back to the app with the following error…

{"code": "token_exchange_failed", "message": "Invalid ID Token", "nativeStackAndroid": {
"0": {"class": "net.openid.appauth.IdToken", "file": "IdToken.java", "lineNumber": 202, "methodName": "validate"}, 
"1": {"class": "net.openid.appauth.AuthorizationService$TokenRequestTask", "file": "AuthorizationService.java", "lineNumber": 698, "methodName": "onPostExecute"}, 
"2": {"class": "net.openid.appauth.AuthorizationService$TokenRequestTask", "file": "AuthorizationService.java", "lineNumber": 564, "methodName": "onPostExecute"}, 
"3": {"class": "android.os.AsyncTask", "file": "AsyncTask.java", "lineNumber": 771, "methodName": "finish"}, 
"4": {"class": "android.os.AsyncTask", "file": "AsyncTask.java", "lineNumber": 199, "methodName": "access$900"}, 
"5": {"class": "android.os.AsyncTask$InternalHandler", "file": "AsyncTask.java", "lineNumber": 788, "methodName": "handleMessage"}, 
"6": {"class": "android.os.Handler", "file": "Handler.java", "lineNumber": 106, "methodName": "dispatchMessage"}, 
"7": {"class": "android.os.Looper", "file": "Looper.java", "lineNumber": 223, "methodName": "loop"},
"8": {"class": "android.app.ActivityThread", "file": "ActivityThread.java", "lineNumber": 7656, "methodName": "main"}, 
"9": {"class": "java.lang.reflect.Method", "file": "Method.java", "lineNumber": -2, "methodName": "invoke"}}, "userInfo": {}},
"10": {"class": "com.android.internal.os.RuntimeInit$MethodAndArgsCaller", "file": "RuntimeInit.java", "lineNumber": 592, "methodName": "run"}, 
"11": {"class": "com.android.internal.os.ZygoteInit", "file": "ZygoteInit.java", "lineNumber": 947, "methodName": "main"}

If I initiate the authorize flow right after then it’s successful (because it doesn’t need to go through Okta again as its just been authorized).
