我试图每 2 分钟跟踪一次我的位置，以检查从我到我家的距离。然而，我得到的结果很奇怪。当我旅行大约 700 米（到另一座建筑物）并在那里停留 2 小时时，结果会说我总是在离家 40 米的范围内。他们会改变，但距离从来没有比这更大。
private void locationSetup(){
int interval = 120000;
// Create the LocationRequest object
mLocationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(interval) // 2 mins, in milliseconds
.setFastestInterval(10000); // 10 seconds, in milliseconds
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
}
因为它认为我离我家很近，而不是到处都是，所以我假设这不是准确性问题，而是缓存问题，但我一直无法在网上找到与此相关的任何内容。
这可能是什么原因造成的？
这是一些日志以显示它的实际效果。距离是离我家的距离，当时我离家700米。
