第一次HTTP調用時出現SocketTimeoutException

當我調用HTTP get，put，post或delete時，我得到了java.net.SocketTimeoutException。但是當我再次單擊該按鈕進行另一次HTTP調用時，則成功。看來AsyncTask/doInBackground不會像這樣失敗。但是第一次HTTP調用使用LoopJ HTTP庫失敗了。掛鉤按鈕以調用下面的方法。 On my first click，我得到上面的exception，但是當我再次點擊時，它是成功的。以下是日誌貓。第一次HTTP調用時出現SocketTimeoutException

而且，似乎這個錯誤並不一致。我已經刪除了應用程序，有時它可以工作，有時它不會。 –

增加超時時間可能是網絡速度太慢建立連接即試試這個

client.setTimeout(70000);//or u can set any time in this

如何確保這真的有效？ –

bcoz我面臨同樣的，然後我增加我的超時，它固定那個時候只是試試這個 –
