URI scheme in your app's manifest is not set up correctly

I am trying to connect my Dropbox, i do not know where this problem comes from but I have edited the manifest file well! what am I doing wrong can anyone help me please...
this is my manifest file :
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
<uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.JurnalCloudApp">
<activity

android:exported="true" />
<activity
android:name=".SyncActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.dropbox.core.android.AuthActivity"
android:configChanges="orientation|keyboard"
android:launchMode="singleTask">
<intent-filter>

<data android:scheme="db-is9rikcfjhforcl" />
<action android:name="android.intent.action.VIEW" />

<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:exported="true"/>
</application>
And the Error is:
Caused by: java.lang.IllegalStateException: URI scheme in your app's manifest is not set up correctly. You should have a com.dropbox.core.android.AuthActivity with the scheme: db-db-is9rstkcfjhlorcl

Your data android:scheme looks correct. Based on the error message, it looks like you're passing in "db-YOURAPPKEY" to the startOAuth2PKCE method to start the app authorization flow, when you should just specify the app key only, that is, "YOURAPPKEY" (no "db-").
If you include that "db-" in your app key in your code, the SDK will expect "db-db-is9rstkcfjhlorcl" (with an extra "db-") in your Manifest, which would be incorrect.

Hmm i deleted the code of that line (db-), this time I encountered this error:
same error without two -db

App icon doesn't appear after implementing deep links to my app

I'm developing an app in Android Studio it works pretty well, but after implementing deep links to my launching activity my app doesn't you the app icon in the menu, I know the app is installed cause in Setting>Applications it appears. I know the problem is in the manifest.xml, so I'll leave a copy down bellow.
I'll love to hear about your solutions, by the way if you are reading this thanks.

You should separate the intent filters, also your manifest file is not well-formatted. you should close the application tag. you can open it with an external application like google chrome, it will tell you if the XML is not in correct format.
<activity android:name=".StartActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<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="myapp" android:host="place"/>
</intent-filter>
<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="https" android:host="myapp.com" android:pathPrefix="/place" />
</intent-filter>
</activity>
it's important that you create separate filters when your intention is to declare unique URLs (such as a specific combination of scheme and host) because multiple <data> elements in the same intent filter are actually merged together to account for all variations of their combined attributes. if you combine them it actually supports https://place and also supports myapp://myapp.com/place.
So you should separate them.

Registering my React Native App to the ShareAction possibilities in Android

I have found a several of reverse examples: sending from a React App to another one using intents.
I have found a blog post of a guy explaining how to do this with IOS.
But not on android. :(
What I understand from there is I need to add something in the `AndroidManifest.xml' file:
<activity android:name=".ShareLink">
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
</activity>
Am I right that this is the APP_ROOT/node_modules/react-native/ReactAndroid/src/main/AndroidManifest.xml file?
Should it look like that then?
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.facebook.react">
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<application />
<activity android:name=".ShareLink">
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
</activity>
</manifest>
How do I create the Intent?
Once my app is in the list (wohoo), how do I get back the data in the React App?
Any help would be highly appreciated. I'm a web developper, love React, but completely n00b to Android.

To get my app in the share list, it wasn't so hard at the end:
In <APP_ROOT>/android/app/src/main/AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.appname">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application
android:allowBackup="true"
android:label="#string/app_name"
android:icon="#mipmap/ic_launcher"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEND" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="text/plain" />
</intent-filter>
</activity>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
</application>
</manifest>
But once it is in the list, to make it accessible to the React App, that was complicated. I detailed the steps in the next answer following another subquestion: https://stackoverflow.com/a/33969430/1620081

my android application doesn't appear on my phone when I installed it

I've developed my first Android application and I have published it on Google play, but when I try to install it, it installs but doesn’t appear on the phone.
Here is the manifestAndroid.xml , I believe that my configuration is the reason why.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="testconverteo.ismail.converteo"
android:versionCode="5"
android:versionName="1.1b" >
<uses-permission android:name = "android.permission.INTERNET" />
<uses-permission android:name = "android.permission.ACCESS_NETWORK_STATE" />
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<!-- Used for Google Play Store Campaign Measurement-->
<application
android:name="Myapp"
android:allowBackup="true"

android:label="#string/app_name"
android:theme="#style/AppTheme" >
<service android:name="com.google.android.gms.analytics.CampaignTrackingService" />
<receiver android:name="com.google.android.gms.analytics.CampaignTrackingReceiver"
android:exported="true">
<intent-filter>
<action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<!-- The BROWSABLE category is required in order for the intent filter to be accessible from a web browser -->
<category android:name="android.intent.category.BROWSABLE" />
<!-- Accepts URIs that begin with "http://www.appconverteo.com/application” -->
<data android:scheme="http"
android:host="www.appconverteo.com"
android:pathPrefix="/application" />
</intent-filter>
</activity>
<activity
android:name=".LoginDisplayActivity"
android:label="#string/title_activity_login_display" />
</application>
</manifest>
What should I do to solve this problem ?
Thanks

you need to separate the .MainActivity intent filter into two different intent filters.
one filter to appear on the launcher and a separate filter to be browsable.
<!-- this makes it available to the launcher -->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<!-- this makes it openable with browser -->
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.BROWSABLE" />
<!-- Accepts URIs that begin with "http://www.appconverteo.com/application” -->
<data android:scheme="http"
android:host="www.appconverteo.com"
android:pathPrefix="/application" />
</intent-filter>
ps.: you should test BEFORE pushing to Google Play.

You should have 2 intent filters inside your manifest, one for each intent type you want to receive.
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http"
android:host="www.appconverteo.com"
android:pathPrefix="/application" />
</intent-filter>
</activity>
From android docs:
http://developer.android.com/guide/components/intents-filters.html
When you want to handle multiple kinds of intents, but only in
specific combinations of action, data, and category type, then you
need to create multiple intent filters.

I had the same issue and my solution was to remove another intent filter I assigned to another activity I tested before. Maybe this helps someone.
