I followed https://developer.android.com/develop/connectivity/wifi/wifi-direct to get my application to create a wifi direct group. And the createGroup() call fails with an rc of 2:

   this.manager.createGroup(this.channel, new WifiP2pManager.ActionListener() {
        @Override
        public void onSuccess() {
            notifyActionToListeners(WIFI_DIRECT_MANAGER_FORMED_CONNECTION_SUCCESSFUL,
                                    "Group created for " + deviceName);
        }

        @Override
        public void onFailure(int reasonCode) {
            notifyActionToListeners(WIFI_DIRECT_MANAGER_FORMED_CONNECTION_FAILED,
                                    "Could not create group for " + deviceName + " rc = " + reasonCode);
            logger.log(WARNING, "Failed to create a group with reasonCode: " + reasonCode);
        }
    });

I call this after WifiP2pManager.initialize() has returned successfully.

I’m testing on both android 13 (Galaxy s20) and android 14 (Galaxy S24).

These are the permissions in the manifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    tools:ignore="ScopedStorage" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
    tools:ignore="ScopedStorage" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission
    android:name="android.permission.ACCESS_WIFI_STATE"
    android:required="true" />
<uses-permission
    android:name="android.permission.CHANGE_WIFI_STATE"
    android:required="true" />
<uses-permission
android:name="android.permission.NEARBY_WIFI_DEVICES"
android:required="true" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

I have prompted for the required permissions. (initialize() was not returning successfully before I did.)

Digging through the Android sources, the rc == 2 might be a BUSY return code. I noticed and API 36 they introduced GROUP_CREATION_FAILURE_REASON_USER_REJECTED.

Has anyone successfully managed a createGroup()?
