Question

我对Android开发并不熟悉，但之前我曾使用过Java（以及其他编程语言）。

我正在使用Android Studio开发我的应用程序，并且在遵循有关访问位置信息的开发人员教程（http://developer.android.com/training/location/index.html）时我已经陷入困境。我了解位置服务需要android.permission.ACCESS_COARSE_LOCATION和/或android.permission.ACCESS_FINE_LOCATION权限，但在将它们添加到我的ApplicationManifest后，我的应用程序仍然会因SecurityException崩溃

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

我遇到过其他几个遇到问题的人，但这些情况通常是错误放置（java.lang.SecurityException: Requires ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION permission），拼写错误（ACCESS_FINE_LOCATION AndroidManifest Permissions Not Being Granted）或大写不正确造成的权限字符串。

这是我的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>

我甚至尝试删除ACCESS_NETWORK_STATE和INTERNET以查看是否会导致其他SecurityExceptions，因为在尝试获取位置信息之前，应用程序需要与HTTP服务器（它成功执行）进行通信。 / p>

似乎我在运行程序时对AndroidManifest上的权限所做的修改没有更新。我还尝试使用Build菜单清理并重建应用程序。

更新：

这是活动的核心;我删除了一些不相关的方法（例如onCreateOptionsMenu（）和onBackPressed（），因为它们与位置无关）

package scd.tt;

import android.app.Fragment;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.SharedPreferences;

你在评论中引用 -

具有保护级别危险的权限必须在运行时通过提示SDK 23中的用户授予，并且不能仅在Manifest中定义。

为什么我的应用程序中没有设置AndroidManifest权限
