I'm completely new to Android development, but I have worked with Java (and other programming languages) before.
I'm using Android Studio to develop my application and I've become stuck when following the developer tutorial on accessing Location information (http://developer.android.com/training/location/index.html). I understand that the Location services require the android.permission.ACCESS_COARSE_LOCATION and/or android.permission.ACCESS_FINE_LOCATION permissions but upon adding them to my ApplicationManifest my application still crashes with a SecurityException
java.lang.SecurityException: Client must have ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission to perform any location operations.
I've come across several other instances of people having trouble, but these have generally been the result of mis-placing (java.lang.SecurityException: Requires ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permission), mis-spelling (ACCESS_FINE_LOCATION AndroidManifest Permissions Not Being Granted) or incorrect capitalization of the permission string.
Here is my 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>
I've even tried to remove ACCESS_NETWORK_STATE and INTERNET to see if this would cause other SecurityExceptions as the application is required to communicate with an HTTP server (which it performs successfully) before it gets attempts to get Location information.
It seems as though modifications I make to the permissions on the AndroidManifest aren't being updated when I run the program. I've also tried to Clean and Rebuild the application using the Build menu.
UPDATE:
Here is the core of the Activity; I've removed some of the unrelated methods (such as onCreateOptionsMenu() and onBackPressed() as they have nothing to do with the Location)
