android - 无法实例化坐标资源系统java.lang.NoClassDefFoundError:org.geotools.factory.Hints

Question

我试图在我的一个项目中使用Geotools Java库，我使用Gradle和14.3版构建了它:

compile 'org.geotools:gt-shapefile:14.3'
compile 'org.geotools:gt-epsg-hsql:14.3'

基本上，任何时候我尝试实例化CoordinateResourceSystem，例如:

CoordinateReferenceSystem crs;
try {
     crs = CRS.decode("epsg:4326"); //also tried DefaultGeographicCRS.WGS84_3D
} catch (FactoryException e) {
     e.printStackTrace();
}

我在运行时收到此错误:

java.lang.NoClassDefFoundError: org.geotools.factory.Hints
at org.geotools.referencing.CRS.<clinit>(CRS.java:181)

到目前为止，我收到的所有建议都与启用Multidex有关，我尝试了指定的gradle组合中的每一个，但无济于事。还尝试了清洁和建筑数十次。无论我做什么，我在运行时都会收到此讨厌的错误。关于为什么会这样有任何想法吗？我可以在 jar 里看到课。

我注意到该依赖项导入了几个jar，所有的jar都具有相似的包名。这些软件包名称可能引起一些困惑吗？

在这里真是一头雾水，在弄清楚如何正确实现此代码之前，我无法继续我的项目。

这是我的logcat。表明ART如何处理某些geotools类(包括culrpit Hints类)存在某种问题。

Answer 1

打破GeoTools引用的“通常方法”是不包含EPSG工厂或包含多个工厂。从您的问题中我看不出是您的问题。如FAQ中所述，您需要一个epsg jar ，通常是gt-epsg-hsql。

您的问题被标记为Android，GeoTools使用基于SPI的工厂查找器系统提供some known issues，但我认为这不是问题。
