android - 在许多设备上，OnLocationChanged将不再起作用

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超级简单的案例来重现问题
在过去的几个月里，我一直在使用与下面的代码非常相似的东西，使用google play服务请求位置更新，它运行良好。现在由于某种原因onlocationchanged不再被调用。发生在整个测试设备范围内。我现在使用Play Services 7.0.0。我请求更新，但什么也没发生。我怀疑它与我最近进行的一次代码更新有关（尽管这与定位系统无关），但我无法找到修复方法。当我恢复提交时，我仍然有一个问题——关于运行良好的旧代码！
我已经将这段代码设置为一个全新的示例应用程序，并使用locationrequest对象的所有选项来获得乐趣，但什么也没有…在调用onconnected之后，日志“onconnected，requestLocationUpdates”之后，一切都将停止。
谢谢你的帮助！

    @Override

        Log.i(TAG, "Connected to GoogleApiClient");
        LocationRequest locationRequest = new LocationRequest();
        locationRequest.setExpirationDuration(30000);
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        Log.d(TAG, "onConnected, requestLocationUpdates");

    @Override
    public void onLocationChanged(Location locationA) {
        Log.d(TAG, locationA.getLongitude() + " :: " + locationA.getLatitude());
    }


    @Override
    public void onConnectionSuspended(int i) {
        Log.d(TAG, "onConnectionSuspended called");
    }

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

}

}

最佳答案

我喜欢在找到答案之前先发问…
上面的代码运行良好，只是没有设置间隔。在locationrequest上，只要调用setinterval（无论需要什么）。晚安。
