我已经使用融合位置 api 来获取纬度和经度，但问题是它说谷歌 API 客户端没有连接，但我还没有。我不知道我错在哪里，请帮助我。
我的飞溅活动，我正在使用融合的 API ：：
注意：： GPS跟踪器是我在这里使用的一个类，它使用位置管理器，我没有在程序i中使用过它。我只是用它来检查 GPS 是打开还是关闭。
我也在清单文件中添加了所有权限。

Google最近发布了一个新的API，它使这个过程变得更加容易，你不再需要GoogleApiClient。我强烈建议您改用此 API。
有关如何使用它，请参阅下面的示例。
FusedLocationProviderClient client = LocationServices.getFusedLocationProviderClient(context);
client.requestLocationUpdates(locationRequest, pendingIntent)
.addOnCompleteListener(task -> {
Log.d("requestLocationUpdates", "result: " + task.getResult());
})
.addOnFailureListener(e -> {
String errorMessage;
if (e instanceof ApiException) {
errorMessage = ((ApiException) e).getStatusMessage();
} else {
errorMessage = e.getMessage();
}
Log.d("requestLocationUpdate", "failed: " + errorMessage);
});
在您的情况下，您可以将context替换为this以引用您的活动，而不是上下文引用。
pendingIntent是 PendingIntent 实例，用于定义如何处理收到的位置更新。
