wso2错误'within'既不是函数扩展也不是聚合属性扩展Android

Question

我正在做一个Android应用，并嵌入Wso2（Siddhi）。我已经将geo-gpl-extension导入为jar文件，但是当我运行该应用程序时，会发生以下错误：

似乎它不会读取或检测jar文件，但是例如如果我在MainActivity.java中执行“ import ort.wso2.siddhi.gpl.distanceFunction”，它将检测到它，所以我不知道它在发生什么。我已将jar文件放入app / libs。

这里是我的build.gradle：

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.13'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
implementation('io.siddhi:siddhi-core:5.1.11') {
    transitive = false
}
implementation('io.siddhi:siddhi-query-api:5.1.7') {
    transitive = false
}
annotationProcessor('io.siddhi:siddhi-annotations:5.1.7') {
    transitive = false
}
implementation('io.siddhi:siddhi-annotations:5.1.7') {
    transitive = false
}
implementation('io.siddhi:siddhi-query-compiler:5.1.7') {
    transitive = false
}
implementation('io.siddhi.extension.map.text:siddhi-map-text:2.0.4') {
    transitive = false
}
implementation('io.siddhi.extension.map.keyvalue:siddhi-map-keyvalue:2.0.4') {
    transitive = false
}
implementation 'com.google.guava:guava:23.0'
implementation('org.apache.log4j.wso2:log4j:1.2.17.wso2v1') {
    transitive = false
}
implementation 'org.osgi:org.osgi.core:6.0.0'
implementation 'org.wso2.orbit.com.lmax:disruptor:3.3.7.wso2v1'
implementation 'org.antlr:antlr4-runtime:4.8'
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.android.support:design:29.0.2'
implementation 'io.dropwizard.metrics:metrics-core:4.1.2'
implementation files('libs/siddhi-gpl-execution-geo-4.0.18.jar')

}

和查询：

 private String app = "@app:name('geofencingSiddhi') " +
        "define stream inStream(id string, latitude double, longitud double, geoJSONGeometryFence string); " +
        "from inStream " +
        "select id, geo:within(longitud, latitud, geoJSONGeometryFence) as resultado " +
        "insert into outputStream;";

有人知道发生了什么吗？

Answer 1

我终于找到了解决错误的方法。我只需要将此行添加到MainActivity.java中：//声明de SiddhiManager变量后

siddhiManager.setExtension("geo:abstract", AbstractGeoOperationExecutor.class); siddhiManager.setExtension("geo:within", GeoWithinFunctionExecutor.class);
