应用程序将在我的真实设备上正常运行但运行正常 模拟器,它立即崩溃,我收到一条错误消息,指出GPS坐标为空。即使打开DDMS,运行应用程序,然后发送坐标并尝试登录,其中onCreate方法将被调用寻找GPS,它仍然注意到空错误(下面)
我创建的所有模拟器都允许GPS但仍然存在错误。首先需要GPS的onCreate代码如下:
// Ensuring a location, loop till find it
do {
// Get the location manager
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// Define the criteria how to select the location provider -> use
// default
Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
Location location = locationManager.getLastKnownLocation(provider);
// Just test displaying
lat = (float) (location.getLatitude());
lng = (float) (location.getLongitude());
} while (lat == 0.0);
具体的错误信息是:
java.lang.IllegalArgumentException: invalid provider: null at android.location.LocationManager.checkProvider(LocationManager.java:1623)
答案 0 :(得分:0)
在Android模拟器上,您可以从null
locationManager.getBestProvider(criteria, false);
