java.net.SocketException: socket failed: EPERM Operation not permitted although AndroidManifest have permits in it

Question

This bug is getting me crezy. I looked in forums but none answered to this particular question. here is my sample code on AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    .
    <uses-permission android:name="android.promission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    .
    <application
        .
        android:usesCleartextTraffic="true"
        .

and although I put all permits as needed and uninstalled + installed the application, it still gives me an exception

W/System.err: java.net.SocketException: socket failed: EPERM (Operation not permitted)
W/System.err:     at java.net.Socket.createImpl(Socket.java:492)
        at java.net.Socket.<init>(Socket.java:446)
        at java.net.Socket.<init>(Socket.java:218)
        at com.diamcom.blue.connect.send(connect.java:23)
        at com.diamcom.blue.sendToServer.sendChanges(sendToServer.java:43)
        at com.diamcom.blue.sendToServer.run(sendToServer.java:25)

Any idea ?

now I see that on forum stackoverflow.com/questions/60203194/… someone offered that the wifi I am connected with in emulator is not allowing me to connect to the api I am calling, but no solution was offered — amnon

So looking through your manifest shows your internet permission is spelt wrongly.

It is: <uses-permission android:name="android.permission.INTERNET" />

not: <uses-permission android:name="android.promission.INTERNET"/>

This might not solve your problem, but it's one step forward to figuring out what's wrong.
