api隐藏函数调用-失败

private void removeAndDeleteGroup(WifiP2pGroup wifiP2pGroup) {
mManager.removeGroup(mChannel, null);
try {
Method getNetworkId = WifiP2pGroup.class.getDeclaredMethod("getNetworkId");
Integer networkId = (Integer) getNetworkId.invoke(wifiP2pGroup);
Method deletePersistentGroup = WifiP2pManager.class.getDeclaredMethod("deletePersistentGroup",
WifiP2pManager.Channel.class, Integer.class, WifiP2pManager.ActionListener.class);
deletePersistentGroup.invoke(mManager, mChannel, networkId, null);
} catch (NoSuchMethodException e) {
Log.e("WIFI", "Could not delete persistent group", e);
} catch (InvocationTargetException e) {
Log.e("WIFI", "Could not delete persistent group", e);
