Question

我有一种简单的方法可以从标准LocationManager获取最近的位置：

fun getLastKnownLocation(context: Context): SimpleLocation {
        val locationManager = context.getSystemService(Context.LOCATION_SERVICE) as LocationManager
        val criteria = Criteria()
        criteria.accuracy = Criteria.ACCURACY_FINE
        val location: android.location.Location?
            location = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, true))
        if (location == null) {
            return SimpleLocation.create(0.0, 0.0)
        }
        return SimpleLocation.create(location.latitude, location.longitude)
    }

然后为它编写简单的测试：

class LocationUtilTest {
    private val locationUtil: LocationUtil = spyk()
    private val context = InstrumentationRegistry.getInstrumentation().context


    @Test
    fun getLastKnownLocation() {
         val l = locationUtil.getLastKnownLocation(context)
         assertNotNull(l)
    }
    }

运行此测试时，它会抛出SecurityException：

注意！

我在stackstace中用下面的 app_package_name 替换了我的应用程序包名称（我的测试程序包名称为app_package_name.test）

所有permissions和uses-feature都在清单中指出：

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

是否因为使用InstrumentationRegistry.getInstrumentation().context而抛出？还是为什么？谢谢！

注意

我知道了this和this。这对我没有帮助。

Answer 1

您的软件包名称或结构有问题。当JVM尝试加载您的类时，它将其包名称识别为无效并抛出SecurityException。

有关参考，请参见https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html

在JUnit测试中调用getLastKnownLocation时得到了SecurityException
