Android Studio中JSON不返回正確

Question

我要問一些有關我的應用程序，我想創建當我打開調試器，這些誤差保持在logcat中永遠重複：

08-19 07:01:10.318 32526-32526/? E/android.os.Debug: failed to load memtrack module: -2 
08-19 07:01:10.658 32537-32537/? E/memtrack: Couldn't load memtrack module (No such file or directory) 
08-19 07:01:10.658 32537-32537/? E/android.os.Debug: failed to load memtrack module: -2 
08-19 07:01:10.658 3816-3816/? E/PGA: PgaSocketInitClientPgaIpc: ioctl() failed: ret -1, errno 22 

我不知道是什麼導致了這個問題，昨天晚上它工作得很好，應用程序仍然被竊聽，但那不是錯誤。請幫我修復我的錯誤： 我正在從forecast.io獲取天氣並在屏幕上顯示它的天氣應用程序，現在我的佈局尚未製作完成，但在調試器中進行測試後發現問題。 從getData（jsonData）返回的Current不會填充mCurrent變量，現在我認爲它沒有正確返回，因爲在查看getData（jsonData）方法時Current變量被填充。

MainActivity

我固定它，在這裏發佈的代碼工作的事情是我試圖修復它之前，我張貼在這裏，但由於無法測試上面列出的原因。 我通過更改模擬器修復了Android錯誤。 我現在使用Bluestacks模擬器。
