Question

目前我尝试为我的Android测试应用程序实现Mock位置，这是我的Mock位置类：

public class MockLocationProvider {
    String providerName;
    Context ctx;

    public MockLocationProvider(String name, Context ctx) {
        this.providerName = name;
        this.ctx = ctx;
        LocationManager lm = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE);
        lm.addTestProvider(providerName, false, false, false, false, false, true, true, 0, 5);
        lm.setTestProviderEnabled(providerName, true);
    }

    public void pushLocation(double lat, double lon) {
        LocationManager lm = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE);
        Location mockLocation = new Location(providerName);
        mockLocation.setLatitude(lat);
        mockLocation.setLongitude(lon);
        mockLocation.setAltitude(0);
        mockLocation.setTime(System.currentTimeMillis());
        lm.setTestProviderLocation(providerName, mockLocation);
    }

    public void shutdown() {
        LocationManager lm = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE);
        lm.removeTestProvider(providerName);
    }
}

这是我的代码，位于测试函数中，用于推送假位置：

MockLocationProvider mock = new MockLocationProvider(LocationManager.NETWORK_PROVIDER, context);
mock.pushLocation(-12.34, 23.45);
LocationManager locMgr = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
LocationListener lis = new LocationListener() {
    public void onLocationChanged(Location location) {
    //You will get the mock location
    }

   @Override
   public void onStatusChanged(String provider, int status, Bundle extras) {

   }

   @Override
   public void onProviderEnabled(String provider) {

   }

   @Override
   public void onProviderDisabled(String provider) {

   }
};
locMgr.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 1, lis, Looper.getMainLooper());

我的问题是requestLocationUpdates函数，如果我不写＆＃34; Looper.getMainLooper（）＆＃34;我得到一个运行时异常，但现在如果我把这个参数，我有一个安全异常。谁可以帮助我？

如果有两个不同的错误，你会得到不同的例外情况。在没有正确的循环器的情况下调用方法时得到的runtimeexception是一个“错误的线程异常”，你试图从非ui线程做UI工作，或者反过来。安全性异常是因为您可能没有正确设置权限。

带有requestLocationUpdates的Android java.lang.SecurityException
