如何设置 Android Mock GPS 位置? [英] How to SET Android Mock GPS location?

问题描述

我在尝试使用 android 模拟位置时遇到问题，我的主要目标是让 android GPS 认为我们在不同的位置，也就是假 GPS.

I'm having a issue while trying to use android mock locations, my main goal is to set the android GPS into thinking we are in a different spot, AKA fake GPS.

我目前尝试了两种不同的类似解决方案，可在这两个网站上使用:

I have currently tried two different similar solutions, avaiable in both this websites:

• 编程丛林
• Mobiarch

两个教程都是 2012 年的，我不知道它们是不是已经过时了，或者我很难实现它们.

Both tutorials are from 2012, I don't know if they are outdated or I'm having a hard time implementing them to work.

首先我确保我有权限:

1. ACCESS_COARSE_LOCATION
2. ACCESS_FINE_LOCATION
3. ACCESS_MOCK_LOCATION *

注意:1 和 2 都被选中，如果它们不可用，我会使用 requestPermissions 函数请求许可.第三个是不可用的，实际上只能在调试模式下通过AndroidManifest.xml添加.

Note: 1 and 2 are both checked, if they are not available I ask permission using requestPermissions function. The third one is not avaiable to be asked, in fact it can only be added through AndroidManifest.xml on debug mode.

我还确保在设置>开发者选项>允许模拟位置中选择了我的应用程序.

I also made sure I have my APP selected in Settings > Developer options > Allow MOCK locations.

毕竟，我已经创建了这个函数，我尝试通过 OnCreate 方法或按钮的 OnClick 调用:

After all this, I have made this function that I tried calling through OnCreate method or OnClick of a button:

public void mockLocation(){
    LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    criteria.setAccuracy( Criteria.ACCURACY_FINE );
    String mocLocationProvider = lm.getBestProvider( criteria, true );
    if ( mocLocationProvider == null ) {
        Toast.makeText(getApplicationContext(), "No location provider found!", Toast.LENGTH_SHORT).show();
        return;
    }
    lm.addTestProvider(mocLocationProvider, false, false,
            false, false, true, true, true, 0, 5);
    lm.setTestProviderEnabled(mocLocationProvider, true);

    Location loc = new Location(mocLocationProvider);
    Location mockLocation = new Location(mocLocationProvider); // a string
    mockLocation.setLatitude(-26.902038);  // double
    mockLocation.setLongitude(-48.671337);
    mockLocation.setAltitude(loc.getAltitude());
    mockLocation.setTime(System.currentTimeMillis());
    lm.setTestProviderLocation( mocLocationProvider, mockLocation);
    Toast.makeText(getApplicationContext(), "Working", Toast.LENGTH_SHORT).show();
}

如果我以这种方式编译和测试，我将收到 Toast:找不到位置提供者！".但是如果我将 mocLocationProvider 更改为:

If I compile and test this way I'll receive the Toast: "No location provider found!". But if I change mocLocationProvider to:

String mocLocationProvider = LocationManager.NETWORK_PROVIDER;

我的 APP 崩溃了，在 LogCat 中，它说在这一行中崩溃了:

I get APP crash and in LogCat it says that crashed during this line:

lm.setTestProviderLocation(mocLocationProvider, mockLocation);

所以我目前没有选择，不知道如何前进.

So I'm currently out of options and don't know how to advance.

推荐答案

必须设置第一:

允许设置中的模拟位置

第二组权限:

ACCESS_COARSE_LOCATIONACCESS_FINE_LOCATIONACCESS_MOCK_LOCATION

ACCESS_COARSE_LOCATION ACCESS_FINE_LOCATION ACCESS_MOCK_LOCATION

第三次使用这个方法:

setMock(some_lat,some_lon,some Accuracy);

private void setMock(double latitude, double longitude, float accuracy) {
 locMgr.addTestProvider (LocationManager.GPS_PROVIDER,
            "requiresNetwork" == "",
            "requiresSatellite" == "",
            "requiresCell" == "",
            "hasMonetaryCost" == "",
            "supportsAltitude" == "",
            "supportsSpeed" == "",
            "supportsBearing" == "",
            android.location.Criteria.POWER_LOW,
            android.location.Criteria.ACCURACY_FINE);

    Location newLocation = new Location(LocationManager.GPS_PROVIDER);

    newLocation.setLatitude(latitude);
    newLocation.setLongitude(longitude);
    newLocation.setAccuracy(accuracy);
    newLocation.setAltitude(0);
    newLocation.setAccuracy(500);
    newLocation.setTime(System.currentTimeMillis());
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        newLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
    }
    locMgr.setTestProviderEnabled(LocationManager.GPS_PROVIDER, true);

    locMgr.setTestProviderStatus(LocationManager.GPS_PROVIDER,
            LocationProvider.AVAILABLE,
            null,System.currentTimeMillis());

    locMgr.setTestProviderLocation(LocationManager.GPS_PROVIDER, newLocation);}
