我试图通过本机接口（android）在cn1中应用FusedLocation提供程序。我已经实现了ConnectionCallbacks和OnConnectionFailedListener接口。它在native android中生成onConnected（），onConnectionSuspended（）和onConnectionFailed（）方法，这些方法在cn1中构建应用程序时不起作用。已实现的方法不适用于本地接口（android）熔合位置提供程序
此外，像onResume，onDestroy等FusedLocationImpl等生命周期方法也不起作用。在未来的日子里，我打算为通用目的创建融合的GPS库。
PS。调试时没有生成错误，也没有任何其他错误。

btn1.addActionListener(e->{
if (fl != null && fl.isSupported()) {
fl.getFusedLocationPermission();
fl.fusedLocation();

});
}
PS。位置权限（ACCESS_FINE_LOCATION）成功。我得到的主要问题是onConnected（）和其他实现的方法不被调用。三江源
CN1位置经理：这不是给人相当的性能，本机融合位置提供

您是否通过Android Studio在设备上进行调试？ –
yeahh我在android studio中调试它 – beck
