我完全不熟悉Android開發,但之前我曾使用過Java(以及其他編程語言)。爲什麼我的應用程序中沒有設置AndroidManifest權限

我正在使用Android Studio來開發我的應用程序,並且在訪問位置信息(http://developer.android.com/training/location/index.html)的開發者教程時我陷入了困境。據我所知,位置服務需要android.permission.ACCESS_COARSE_LOCATION和/或android.permission.ACCESS_FINE_LOCATION權限,但在將它們添加到我的ApplicationManifest我的應用程序有一個SecurityException

java.lang.SecurityException: Client must have ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission to perform any location operations. 

我遇到的麻煩有幾個人等情況下仍然崩潰,但這些通常是錯誤排列(java.lang.SecurityException: Requires ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permission),錯誤拼寫(ACCESS_FINE_LOCATION AndroidManifest Permissions Not Being Granted)或權限字符串的大寫不正確的結果。

這裏是我的ApplicationManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="scd.tt" > 

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
    <uses-permission android:name="android.permission.INTERNET" /> 

    <uses-sdk 
     android:minSdkVersion="14" 
     android:targetSdkVersion="23" /> 

    <application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher_tt_v2" 
     android:label="@string/app_name" 
     android:theme="@style/TT_Theme"> 
     <activity 
      android:name=".MainActivity" 
      android:theme="@style/TT_Theme.NoActionBar"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
     <activity android:name=".LoginActivity" android:theme="@style/TT_Theme.NoActionBar" /> 
     <activity android:name=".IndexActivity" /> 
    </application> 

</manifest> 

我甚至試圖刪除許可權和網上看到的,如果在應用程序需要與HTTP服務器進行通信,這將導致其他SecurityExceptions(它執行成功),然後它試圖獲取位置信息。

看來好像我對AndroidManifest的權限所做的修改在我運行程序時沒有被更新。我也嘗試使用Build菜單清理和重建應用程序。

UPDATE:

這裏是活動的核心;我已經刪除了一些不相關的方法(如onCreateOptionsMenu()和onBackPressed(),因爲他們什麼都沒有做的位置)

您是否在模擬器上運行此程序? – Actiwitty

到目前爲止,您的活動中有哪些代碼? – fractalwrench

是的,應用程序正在模擬器中運行以進行測試。它基於使用API​​/SDK版本23的x86平臺上的Nexus 5。 –
