android6.0以上開啟熱點失敗
最近在做手機移動端檔案傳輸app，該專案需要一端開啟熱點，另一端連線該熱點，從而兩個段之間建立區域網，進而通過socket通訊實現檔案傳輸功能，隨著測試的深入，發現，如果設定targetSdkversion >= 23的時候熱點建立失敗。百度了一下，全是許可權的問題，通過列印我的log，也提示是許可權問題，log如下：

好吧，但是我命名在menifest已經註冊了write_settings許可權了啊？
不然怎麼說自古網路出人才，http://blog.csdn.net/chengkaizone/article/details/53765934，然後選擇開啟，編譯安裝，正常開啟熱點，marks一下。
