我一直在試用各種網站上顯示的使用PHP連接到MySQL數據庫的教程。我不知道下面的代碼有什麼問題。任何人都可以告訴我我需要做什麼。'traces.txt':權限被拒絕

IHAVE這個問題:不幸的是,該市已停止

在logcat的:2月1日至17日:57:18.790:E/dalvikvm(325):無法打開堆棧跟蹤文件「/數據/ ANR/traces.txt「:權限被拒絕

我嘗試CHANE權限,但我不能因爲IAM在AVD

不是root這是我的PHP代碼

<?php 
mysql_connect("localhost","???????????","......;"); 
mysql_select_db("???????????"); 
$sql=mysql_query("select * from users"); 
while($row=mysql_fetch_assoc($sql)) 
$output[]=$row; 
print(json_encode($output)); 
mysql_close(); 
?>

這是不是在你的程序中的實際問題之後。您的程序(或可能是某個與電話無關的程序)因其他原因而崩潰。這個消息因爲android bug報告機制中的配置錯誤而發生。查找並修復您的實際問題,並忽略此問題。 – 2014-03-28 17:29:02

將這個線整理你的應用程序標籤

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>

哦,在這裏你使用的是InputStream,所以我認爲可能需要使用HttpConnection的setDoInput(true)。 – Lucifer 2012-01-18 11:37:10
