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

问题描述

描述

我在尝试使用android模拟位置时遇到问题，我的主要目标是将android GPS设置为认为我们处于不同的位置，又名假GPS。

当前尝试次数

我目前尝试了两种不同的类似解决方案，网站：

• 编程丛林


• Mobiarch

这两个教程都是从2012年开始的，我不知道它们是否过时，或者我很难实现它们。

编码开发

首先我确定我有权限： strong>

ACCESS_FINE_LOCAT ION

ACCESS_MOCK_LOCATION *

注意：1和2都被检查，如果它们不可用我使用 requestPermissions 函数请求权限。第三个是不可行的，实际上它只能通过 AndroidManifest.xml 在调试模式下添加。

我也做了确定我在 Settings> Developer options> Allow MOCK locations 中选择了我的APP。

毕竟，我已经制作了这个功能，通过OnCreate方法或按钮的OnClick调用：

  public void mockLocation（）{
 LocationManager lm =（LocationManager） getSystemService（Context.LOCATION_SERVICE）; 
标准标准=新标准（）; 
 criteria.setAccuracy（Criteria.ACCURACY_FINE）; 
字符串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）; 
 
位置loc =新位置（mocLocationProvider）; 
位置mockLocation =新位置（mocLocationProvider）; //一个字符串
 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（）; 
 
 $ / code> 

如果我以这种方式进行编译和测试，我会收到 Toast ：找不到位置提供商！。但是，如果我将mocLocationProvider更改为：



 字符串mocLocationProvider = LocationManager.NETWORK_PROVIDER; 
  

我得到应用程序崩溃，并且在LogCat中说它在此行崩溃：

  lm.setTestProviderLocation（mocLocationProvider，mockLocation）; 
  

所以我现在没有选择，不知道如何前进。

解决方案

您必须设置准确性和ElapsedRealtimeNanos值



  location.setAccuracy（...）; 
 if（Build.VERSION.SDK_INT> = Build.VERSION_CODES.JELLY_BEAN_MR1）{
 location.setElapsedRealtimeNanos（SystemClock.elapsedRealtimeNanos（））; 
} 
  

否则会抛出IllegalArgumentException。

如果位置不完整，则抛出IllegalArgumentException

UPDATE



如果你模拟网络提供者

  String mocLocationProvider = LocationManager.NETWORK_PROVIDER ; 
  

然后您将通过网络提供商接收模拟位置，

  LocationListener listener = new LocationListener（）{
 ... 
 void onLocationChanged（位置位置）{
 
} 
}; 
 locationManager.requestLocationUpdates（LocationManager.NETWORK_PROVIDER，...，listener）; 
  

而且每当你调用setTestProviderLocation方法，那么onLocationChanged回调就会被触发！


Description

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.

Current attempts

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

• Programming Jungle
• Mobiarch

Both tutorials are from 2012, I don't know if they are outdated or I'm having a hard time implementing them to work.

Coding development

First I make sure I have permissions:

1. ACCESS_COARSE_LOCATION
2. ACCESS_FINE_LOCATION
3. ACCESS_MOCK_LOCATION *

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.

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

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();
}

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;

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

lm.setTestProviderLocation(mocLocationProvider, mockLocation);

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

解决方案

You must set accuracy and ElapsedRealtimeNanos values

location.setAccuracy(...);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
    location.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
}

Otherwise it throws IllegalArgumentException.

@throws IllegalArgumentException if the location is incomplete

UPDATE

If you mock Network provider

String mocLocationProvider = LocationManager.NETWORK_PROVIDER;

then you will receive mock location through Network provider,

LocationListener listener = new LocationListener(){
    ...
    void onLocationChanged(Location location){

    }
};
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, ..., listener);

And whenever you invoke setTestProviderLocation method, then onLocationChanged callback will be triggered !
