Question

免责声明：我知道还有其他类似的问题，但我想尝试为其他人创建一个更简单的案例来重新创建问题

过去几个月，我一直在使用与以下代码非常相似的内容来使用Google Play服务请求位置更新，并且工作正常。现在由于某种原因onLocationChanged不再被调用。发生在各种测试设备上。我现在正在使用Play Services 7.0.0。我要求更新，没有任何反应。我怀疑它与我最近的代码更新有关（尽管与位置系统无关），但我无法找到修复程序。当我还原提交时，我仍然有问题 - 在旧代码上工作正常！

我已将此代码设置为一个全新的示例应用程序，并使用locationRequest对象的所有选项进行娱乐，但没有任何内容......一切都在日志之后停止，＆＃34; onConnected，requestLocationUpdates＆＃34;调用onConnected后。

感谢您的帮助！

类似：

Android GPS onLocationChanged never called
android onLocationChanged never called
onLocationChanged() never called

    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.d(TAG, "onConnectionFailed called");
    }

}

我喜欢在找到答案之前发布问题的方式......

上面的代码工作正常，我只是没有设置间隔。在LocationRequest上，只需调用setInterval（无论需要什么）......晚安。
