推荐答案
如果您只想与现有的WiFiP2p连接区别开,则不只是调用WiFiP2pManager#removeGroup
.与设备GO或对等设备无关.
If you want just to discinnect from existant WiFiP2p connection, than just call WiFiP2pManager#removeGroup
. Doesnt matter is device GO or peer.
如果您正在谈论忘记持久性组-您也可以将其删除.但这只能通过反思来实现.而且无论设备GO还是对等设备.
If you are talking about forgeting persistant groups - u can also remove it. But it can only be achieved via reflection. And also no matter is device GO or peer.
manager.removeGroup(channel, new WifiP2pManager.ActionListener() {
@Override
public void onSuccess() {
Log.d(TAG, "removeGroup success");
deletePersistentGroup(group);
}
@Override
public void onFailure(int reason) {
Log.d(TAG, "removeGroup fail: " + reason);
}
});
其中manager
是WiFip2pManager的实例.而deletePersistanteGroup(WiFiP2pGroup group)
是:
Where manager
is an instance of WiFip2pManager. And deletePersistanteGroup(WiFiP2pGroup group)
is:
private void deletePersistentGroup(WifiP2pGroup wifiP2pGroup) {
try {
Method getNetworkId = WifiP2pGroup.class.getMethod("getNetworkId");
Integer networkId = (Integer) getNetworkId.invoke(wifiP2pGroup);
Method deletePersistentGroup = WifiP2pManager.class.getMethod("deletePersistentGroup",
WifiP2pManager.Channel.class, int.class, WifiP2pManager.ActionListener.class);
deletePersistentGroup.invoke(manager, channel, networkId, new WifiP2pManager.ActionListener() {
@Override
public void onSuccess() {
Log.e(TAG, "deletePersistentGroup onSuccess");
}
@Override
public void onFailure(int reason) {
Log.e(TAG, "deletePersistentGroup failure: " + reason);
}
});
} catch (NoSuchMethodException e) {
Log.e("WIFI", "Could not delete persistent group", e);
} catch (InvocationTargetException e) {
Log.e("WIFI", "Could not delete persistent group", e);
} catch (IllegalAccessException e) {
Log.e("WIFI", "Could not delete persistent group", e);
}
}
UPD
要成为GO,您应在向对方发送邀请之前调用WiFiP2pManager#createGroup().
To became a GO you should call WiFiP2pManager#createGroup() before sending invites to peers.
