I'm writing some unit tests in my android application and every call to Esri's Android Runtime SDK throws a null pointer exeption. The method @Test public void addition_isCorrect() { SpatialReference wgs84 = SpatialReferences.getWgs84(); assertEquals(4, 2 + 2); } ... breaks with the following stack trace: java.lang.ExceptionInInitializerError at com.esri.arcgisruntime.internal.jni.CoreSpatialReference.<clinit>(SourceFile:40) at com.esri.arcgisruntime.geometry.SpatialReference.<init>(SourceFile:149) at com.esri.arcgisruntime.geometry.SpatialReference.create(SourceFile:86) at com.esri.arcgisruntime.geometry.SpatialReferences.<clinit>(SourceFile:26) at br.gov.ba.conder.vistorias.ExampleUnitTest.addition_isCorrect(ExampleUnitTest.java:18) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Caused by: java.lang.NullPointerException at com.esri.arcgisruntime.ArcGISRuntimeEnvironment.c(SourceFile:250) at com.esri.arcgisruntime.ArcGISRuntimeEnvironment.<clinit>(SourceFile:50) ... 27 more What I'm doing wrong?

I'm developing an android app using ArcGIS Runtime SDK for Android 100.6.0 and it is getting a SSLHandshakeException since I updated my app to use a network security config. The app do requests to two servers. One of them is a REST API in a develpment server accessible only in my company network. The other one is a public server running an ArcGIS Server. The ArcGIS Server's domain is able to communicate over TLS 1.2. So, I expect everything to works just adding a rule to my private development server. This is the content of my network security config: <?xml version="1.0" encoding="utf-8"?> <network-security-config xmlns:android="http://schemas.android.com/apk/res/android"> <domain-config cleartextTrafficPermitted="true"> <domain includeSubdomains="true">172.17.1.14</domain> </domain-config> </network-security-config>‍‍‍‍‍‍ Unfortunately, any requests to my ArcGIS Server (using ArcGIS Runtime SDK for Android) are resulting in the following exception: Caused by: java.security.cert.CertificateException: Domain specific configurations require that hostname aware checkServerTrusted(X509Certificate[], String, String) is used at android.security.net.config.RootTrustManager.checkServerTrusted(RootTrustManager.java:111) at com.esri.arcgisruntime.internal.e.a.a.checkServerTrusted(SourceFile:161) at com.android.org.conscrypt.Platform.checkServerTrusted(Platform.java:212) at com.android.org.conscrypt.ConscryptFileDescriptorSocket.verifyCertificateChain(ConscryptFileDescriptorSocket.java:404) at com.android.org.conscrypt.NativeCrypto.SSL_do_handshake(Native Method) at com.android.org.conscrypt.NativeSsl.doHandshake(NativeSsl.java:375) at com.android.org.conscrypt.ConscryptFileDescriptorSocket.startHandshake(ConscryptFileDescriptorSocket.java:224)‍‍‍‍‍‍‍‍ Since my ArcGIS Server server has a valid certificate and is TLS 1.2 aware, it would not happen, right? The following network security config works fine, but it is insecure: <?xml version="1.0" encoding="utf-8"?> <network-security-config xmlns:android="http://schemas.android.com/apk/res/android"> <base-config cleartextTrafficPermitted="true"> <trust-anchors> <certificates src="system" /> </trust-anchors> </base-config> </network-security-config>‍‍‍‍‍‍‍‍ In addiction, I read that Facebook's Audience Network Android SDK also experienced issues with the network security configuration because they cache files at localhost. I've tried the same solution proposed by them but it also didn't work: https://developers.facebook.com/docs/audience-network/android-network-security-config/ What did I have done wrong? Does the Runtime SDK do intermediate requests like FB? Sniffing the android emulator network did not show up any requests other then expected. ... View more

I created a mobile style file with two classes: point and line, each one with one key - point_key and line_key, respectively. I'm able to load the *.stylx file in my android application and retrieve those two symbols. Then, every time I add a new graphic to one GraphicsOverlay, I have to check the geometry type and set the symbol properly. I would like to create a Renderer and set it to my GraphicsOverlay so no matter what I'm adding to it, the render should identify the geometry type and draw it accordly. Is possible to create such Renderer? So, if I add a point, the renderer applyes the point_key symbol, or in case the geometry is a line, the same renderer applyes the line_symbol. ... View more

I have a feature service with a 1-N related table. The related table has an URL attribute which contains an hyperlink. Realize that one feature can has many URL images related to it. I need to configure the pop-up to show images from the URLs. How can I accomplish that? The solution presented here did not worked. ... View more

Companies frequently needs to show some information in a way in which there are no elements in Operations Dashboard that fits the requirements. Would be great if Operations Dashboard could allow create own widgets. This feature was in Operations Dashboard for Desktop, but this product was discontinueded in Jan-1-2017. Reference: * Video showing how to create extensions for Operations Dashboard for Desktop - also worked with the web version: Developing Custom Extensions in Operations Dashboard for ArcGIS - YouTube  * Operations Dashboard Extensibility reference: Extend Operations Dashboard | Guide | ArcGIS API for JavaScript 3.27  ...
