Question

我正在尝试开发Google地图应用程序。

演示应用程序在真实设备上运行良好，但在模拟器上失败。

logcat输出如下：

java.lang.RuntimeException: Unable to start activity ComponentInfo{il.co.talkie.mapdemo/il.co.talkie.mapdemo.MapDemoActivity}: java.lang.SecurityException: "passive" location provider requires ACCESS_FINE_LOCATION permission.

MapDemoActivity的第170行是

locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0,0, this);

清单文件具有这些权限（否则它将无法在真实设备上运行），如下所示：

的Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest

            <category android:name="android.intent.category.LAUNCHER" />

    </activity>
</application>

</manifest>

我想使用模拟器获取我的位置 - 它显示谷歌地图，它找到我提供的地址的位置，但它拒绝获取我的位置 - 所以我无法正确计算距离。

有什么问题？我使用的模拟器是为API 23和目标Google API创建的。欢迎任何帮助。

Answer 1

如果您在Android M上使用模拟器，您将需要请求用户的许可，尽管您的清单。参见

ACCESS_FINE_LOCATION permission error emulator only

Android M Google API's to use Google Maps and other permissions

您可以查看文章/教程，例如this使用新系统或仅定位较低的API＆lt; = 22

Answer 2

由于此问题而发生错误：

引起：java.lang.SecurityException：＆＃34;被动＆＃34;位置提供程序需要ACCESS_FINE_LOCATION权限。

只需向您的应用清单添加新权限：

uses-permission android：name =＆＃34; android.permission.ACCESS_FINE_LOCATION＆＃34; /＆gt;

无法使用emulataor获取我的位置
