所以有一個PHP文件,我發送數組到我的Android設備。在我的設備接收到數據後,它將它轉換爲一個字符串,之後我試圖獲取由PHP創建的assoc數組索引。這裏是PHP代碼從之前的樣本:JSONException,而試圖將數據轉換爲字符串
if(mysql_num_rows($query)){
$output = array('message' => 'Group added to your database', 'succes' => 'true');
}else{
$output = array('message' => 'Wrong username/password combination', 'succes' => 'false');
}
print(json_encode($output));
,這裏是我的Android項目中的代碼看起來像:
protected void onPostExecute(String result) {
dialog.dismiss();
try{
jArray = new JSONArray(result);
JSONObject json_data=null;
for(int i = 0; i < jArray.length(); i++){
json_data = jArray.getJSONObject(i);
String getMessage = json_data.getString("message");
showToast(getMessage);
}
}
catch(JSONException je){
Log.e("log_tag", "Error (JSONException): "+je.toString());
showToast(result);
}
catch (ParseException pe) {
pe.printStackTrace();
}
}
錯誤日誌:
01-08 16:35:55.896: E/log_tag(647): Error (JSONException): org.json.JSONException: Value {"message":"Group added to your database","success":"true"} of type org.json.JSONObject cannot be converted to JSONArray

Json異常中提供了哪些細節?成功的拼寫也是成功的。 – 2012-01-08 10:51:48
