我正在尝试设置一些保护措施，以防止人们使用模拟位置来操纵我的应用.我意识到不可能100％阻止...我只是在尽我所能.

I'm trying to set some protection against people using mock locations to manipulate my app. I realise that it's impossible to prevent 100%... I'm just trying to do what I can.

该应用在其主要活动中使用Google定位服务(游戏服务的一部分).

The app uses Google location services (part of play services) in its main activity.

onLocationChanged()方法为:

The onLocationChanged() method is:

public void onLocationChanged(Location location) { this.mCurrentLocation = location; if (Build.VERSION.SDK_INT > 17 && mCurrentLocation.isFromMockProvider()) { Log.i(TAG, "QQ Location is MOCK"); // TODO: add code to stop app // otherwise, currently, location will never be updated and app will never start } else { Double LAT = mCurrentLocation.getLatitude(); Double LON = mCurrentLocation.getLongitude(); if ((LAT.doubleValue() > 33.309171) || (LAT.doubleValue() < 33.226442) || (LON.doubleValue() < -90.790165) || (LON.doubleValue() > -90.707081)) { buildAlertMessageOutOfBounds(); } else if (waiting4FirstLocationUpdate) { Log.i(TAG, "YYY onLocationChanged() determines this is the FIRST update."); waiting4FirstLocationUpdate = false; setContentView(R.layout.activity_main); startDisplayingLists(); } } }

位置服务可以完美运行，并且通常与该应用程序都很好，但是当我在具有Android Studio(Nexus One API 23)的模拟器中运行该应用程序，并使用扩展控件(模拟)设置位置时，应用程序仍然可以正常运行，因此看起来情况如下:

The location services work perfectly and all is well with the app in general, but when I run the app in an emulator with Android Studio (Nexus One API 23), and I set the location using extended controls (mock), the app just continues to work as normal, and so it seems that the condition:

if (Build.VERSION.SDK_INT > 17 && mCurrentLocation.isFromMockProvider())

返回假.

这对我来说没有任何意义.有谁知道为什么会这样?

This doesn't make any sense to me. Does anyone know why this would happen?

谢谢！

推荐答案

简短答案:.isFromMockProvider 不可靠.某些虚假位置无法正常检测到. 我花了大量时间对此进行了研究，并编写了关于它的详细博客文章.

The short answer: .isFromMockProvider is unreliable. Some fake locations are not properly detected as such. I have spent an extensive amount of time researching this and written a detailed blog post about it.

我还花了一些时间来找到一种解决方案，以在所有最新/相关的Android版本中可靠地抑制模拟位置，并制作了一个实用程序类，称为 LocationAssistant ，即可完成工作.

I also spent time to find a solution to reliably suppress mock locations across all recent/relevant Android versions and made a utility class, called the LocationAssistant, that does the job.

简而言之(使用上述 LocationAssistant ):

In a nutshell (using the aforementioned LocationAssistant):

在清单中设置权限，并在gradle文件中设置Google Play服务.

Set up permissions in your manifest and Google Play Services in your gradle file.

复制文件 LocationAssistant.java 到您的项目.

在活动"的onCreate()方法中，使用所需参数实例化LocationAssistant.例如，要大致每5秒接收一次高精度位置更新并拒绝模拟位置，请致电new LocationAssistant(this, this, LocationAssistant.Accuracy.HIGH, 5000, false).最后一个参数指定不应允许模拟位置.

In the onCreate() method of your Activity, instantiate a LocationAssistant with the desired parameters. For example, to receive high-accuracy location updates roughly every 5 seconds and reject mock locations, call new LocationAssistant(this, this, LocationAssistant.Accuracy.HIGH, 5000, false). The last argument specifies that mock locations shouldn't be allowed.

使用活动"启动/停止助手，并通知其权限/位置设置更改(请参见文档以获取详细信息).

Start/stop the assistant with your Activity and notify it of permission/location settings changes (see the documentation for details).

享受onNewLocationAvailable(Location location)中的位置更新.如果您选择拒绝模拟位置，则仅在非模拟位置调用该回调.

Enjoy location updates in onNewLocationAvailable(Location location). If you chose to reject mock locations, the callback is only invoked with non-mock locations.

还有更多方法可以实现，但实际上就是这样.显然，有一些方法可以绕过使用root的设备进行模拟提供程序检测，但是对于非rooted的库存设备，拒绝应该可靠地工作.

There are some more methods to implement, but essentially this is it. Obviously, there are some ways to get around mock provider detection with rooted devices, but on stock, non-rooted devices the rejection should work reliably.
