選擇“傳輸文件”模式時，連接到PC的電話已崩潰

Question

我想在Android Oreo上將某些東西推入我的手機中，但是當我的手機連接到PC時，我選擇了模式Transfer files ，它已崩潰。這是我崩潰的日志。

請查看日志：

我已經解決了問題，因為function（BoostFramework.perfHint）中的第二個參數為NULL。因此在MtpService.java中使用getApplicationContext（）。getPackageName（）而不是null，請看下面的內容：

-mPerfBoost.perfHint(BoostFramework.VENDOR_HINT_MTP_BOOST,null,Integer.MAX_VALUE,-1);
+mPerfBoost.perfHint(BoostFramework.VENDOR_HINT_MTP_BOOST,getApplicationContext().getPackageName(),Integer.MAX_VALUE,-1);
