Question

我有android应用程序，我们最近已从22更改为API级别26。

我很高兴该应用是否具有ACCESS_COARSE_LOCATION或ACCESS_FINE_LOCATION权限之一。

我发现但无法解决的一个问题是它给出了类似的异常 “ java.lang.SecurityException：“被动”位置提供者需要ACCESS_FINE_LOCATION权限”

我的Android清单文件具有：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

我也有这种例外情况：

Process: edu.syr.ischool.orange.indoormap3, PID: 12666
    java.lang.SecurityException: "passive" location provider requires ACCESS_FINE_LOCATION permission.
        at android.os.Parcel.readException(Parcel.java:2005)
        at android.os.Parcel.readException(Parcel.java:1951)
        at android.location.ILocationManager$Stub$Proxy.getLastLocation(ILocationManager.java:802)
        at android.location.LocationManager.getLastKnownLocation(LocationManager.java:1220)
        at utils.CheckinUtils.checkLocation(CheckinUtils.java:100)
        at utils.CheckinUtils.resume(CheckinUtils.java:247)

也是我的checkinUtil-> checkLocation方法

 if (ActivityCompat.checkSelfPermission(activity, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(activity, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            return;
        }
        locationManager = (LocationManager) activity.getSystemService(serviceString);
        Location lastKnow =  locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);

我已根据https://developer.android.com/reference/android/location/LocationManager#getLastKnownLocation(java.lang.String)

中的说明检查了其中任何一个的许可

仍然，它为ACCESS_FINE_LOCATION给出了一个异常，但是当它通过if条件并给出了安全性异常时，它应该具有ACCESS_COARSE_LOCATION权限。那么，为什么应用程序崩溃了？

Answer 1

据我了解，您仅在检查是否授予许可。

如果在未授予权限的情况下您的应用程序/代码未结束，请确保通过调用...来请求权限。

ActivityCompat.requestPermissions(this, permissionsStringArray,requestCodeInt);

另外，在检查自我权限时，请尝试使用ContextCompat代替ActivityCompat

Answer 2

解决方案：

代替此行：

if (ActivityCompat.checkSelfPermission(activity, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(activity, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

写下：

if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

您正在从Android获取内置权限，这可能是错误。

您必须获得清单中提到的清单的许可。

因此，它应该只是android.Manifest.permission.ACCESS_FINE_LOCATION而不是Manifest.permission.ACCESS_FINE_LOCATION

Answer 3

Android清单文件应如下所示：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature android:name="android.hardware.location.gps" />

您可以在这里Request User Permissions中找到更多详细信息并使用您的Java代码代替： Location lastKnow = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);如下

  try {
    Location lastKnow1 = locationManager.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER);
    Location lastKnow2 = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    Location lastKnow3 = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
    if(lastKnow1 != null){
       --- your code ---
    } if(lastKnow2 != null){
       --- your code ---
    } if(lastKnow3 != null){
       --- your code ---
    } else {
       --- Toast ---
    }
  } catch (Exception e) {
            e.printStackTrace();
          }

使用上述代码，您将永远不会遇到异常问题。 **快乐编码**
