How to SET Android Mock GPS location?
提问by Guilherme Garcia da Rosa
Description
描述
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 设置为认为我们在不同的位置，也就是假 GPS。
Current attempts
当前尝试
I have currently tried two different similar solutions, avaiable in both this websites:
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：
Both tutorials are from 2012, I don't know if they are outdated or I'm having a hard time implementing them to work.
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。

First I make sure I have permissions:
首先，我确保我有权限：
- ACCESS_COARSE_LOCATION
- ACCESS_FINE_LOCATION
- ACCESS_MOCK_LOCATION*
- ACCESS_COARSE_LOCATION
- ACCESS_FINE_LOCATION
- ACCESS_MOCK_LOCATION*
Note: 1 and 2 are both checked, if they are not available I ask permission using requestPermissionsfunction. The third one is not avaiable to be asked, in fact it can only be added through AndroidManifest.xmlon debug mode.
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。
I also made sure I have my APP selected in Settings > Developer options > Allow MOCK locations.
我还确保在Settings > Developer options > Allow MOCK location 中选择了我的应用程序。
After all this, I have made this function that I tried calling through OnCreate method or OnClick of a button:
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：
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:
如果我以这种方式编译和测试，我将收到Toast：“找不到位置提供程序！” . 但是，如果我将 mocLocationProvider 更改为：
String mocLocationProvider = LocationManager.NETWORK_PROVIDER;
I get APP crash and in LogCat it says that crashed during this line:
我得到 APP 崩溃，在 LogCat 中它说在这一行中崩溃了：
lm.setTestProviderLocation(mocLocationProvider, mockLocation);
So I'm currently out of options and don't know how to advance.
所以我目前别无选择，不知道如何推进。

you must set first:
你必须先设置：
allow mock location in setting
在设置中允许模拟位置
second set permissions:
第二组权限：
ACCESS_COARSE_LOCATION ACCESS_FINE_LOCATION ACCESS_MOCK_LOCATION
ACCESS_COARSE_LOCATION ACCESS_FINE_LOCATION ACCESS_MOCK_LOCATION
third use this method :
第三种使用此方法：
setMock(some_lat,some_lon,some accuracy);
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);}

You must set accuracy and ElapsedRealtimeNanos values
您必须设置准确度和 ElapsedRealtimeNanos 值
location.setAccuracy(...);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
location.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
}
Otherwise it throws IllegalArgumentException.
否则它会抛出 IllegalArgumentException。
@throws IllegalArgumentException if the location is incomplete
如果位置不完整，@throws IllegalArgumentException
UPDATE
更新
If you mock Network provider
如果您模拟网络提供商
String mocLocationProvider = LocationManager.NETWORK_PROVIDER;
then you will receive mock location through Network provider,
然后您将通过网络提供商收到模拟位置，
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 !
并且每当您调用 setTestProviderLocation 方法时，就会触发 onLocationChanged 回调！

from @Blackkara's answer and comments, this is the final code, and do not forget to set the location mode to device only(GPS)
来自@Blackkara 的回答和评论，这是最终代码，不要忘记将位置模式设置为仅设备（GPS）
LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy( Criteria.ACCURACY_FINE );
String mocLocationProvider = LocationManager.GPS_PROVIDER;//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());
mockLocation.setAccuracy(1);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
mockLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
}
lm.setTestProviderLocation( mocLocationProvider, mockLocation);
Toast.makeText(getApplicationContext(), "Working", Toast.LENGTH_SHORT).show();
