    <p>I think there's some problem with IntelliJ when it generates the R.java file, which leads to a problem in AndroidAnnotations because it can't resolve the resource id for my layout.</p> <p>Here's my activity:</p> <pre><code>package com.airlocksoftware.canvastest; import android.app.Activity; import android.os.Bundle; import com.googlecode.androidannotations.annotations.EActivity; @EActivity(R.layout.main) public class MyActivity extends Activity { /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } } </code></pre> <p>What's weird is that even if I comment out the annotation, and do <code>setContentView(R.layout.main)</code>, it works fine even though R.java is never imported.</p> <p>By the way, the layout is just a simple "Hello World". Nothing weird going on there.</p> <p>No matter what I do, I can't get AndroidAnnotations to generate <code>CanvasActivity_.java</code>. My pom.xml looks like this:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;groupId&gt;com.airlocksoftware.canvastest&lt;/groupId&gt; &lt;artifactId&gt;CanvasTest&lt;/artifactId&gt; &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt; &lt;properties&gt; &lt;project.build.sourceEncoding&gt;UTF-8&lt;/project.build.sourceEncoding&gt; &lt;android.version&gt;4.2.2_r2&lt;/android.version&gt; &lt;android.platform&gt;17&lt;/android.platform&gt; &lt;androidannotations.version&gt;2.7.1&lt;/androidannotations.version&gt; &lt;java.version&gt;1.6&lt;/java.version&gt; &lt;/properties&gt; &lt;repositories&gt; &lt;repository&gt; &lt;id&gt;local-repo&lt;/id&gt; &lt;url&gt;file:///${env.HOME}/.m2/repository&lt;/url&gt; &lt;/repository&gt; &lt;/repositories&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;android&lt;/groupId&gt; &lt;artifactId&gt;android&lt;/artifactId&gt; &lt;version&gt;${android.version}&lt;/version&gt; &lt;scope&gt;provided&lt;/scope&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;com.googlecode.androidannotations&lt;/groupId&gt; &lt;artifactId&gt;androidannotations&lt;/artifactId&gt; &lt;version&gt;${androidannotations.version}&lt;/version&gt; &lt;scope&gt;provided&lt;/scope&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;com.googlecode.androidannotations&lt;/groupId&gt; &lt;artifactId&gt;androidannotations-api&lt;/artifactId&gt; &lt;version&gt;${androidannotations.version}&lt;/version&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt; &lt;version&gt;2.5.1&lt;/version&gt; &lt;configuration&gt; &lt;source&gt;${java.version}&lt;/source&gt; &lt;target&gt;${java.version}&lt;/target&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;plugin&gt; &lt;groupId&gt;com.jayway.maven.plugins.android.generation2&lt;/groupId&gt; &lt;artifactId&gt;android-maven-plugin&lt;/artifactId&gt; &lt;version&gt;3.4.0&lt;/version&gt; &lt;configuration&gt; &lt;sdk&gt; &lt;platform&gt;${android.platform}&lt;/platform&gt; &lt;/sdk&gt; &lt;undeployBeforeDeploy&gt;true&lt;/undeployBeforeDeploy&gt; &lt;/configuration&gt; &lt;extensions&gt;true&lt;/extensions&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; &lt;/project&gt; </code></pre> <p>The annotation processing <a href="https://i.imgur.com/BCrlyYa.png" rel="nofollow noreferrer">set up like shown in this screenshot.</a> </p> <p><img src="https://i.stack.imgur.com/27pqx.png" alt="annotation processing"></p> <p>Basically I setup the processor path to point to the jar files in my local maven repo, as <a href="http://www.ashokgelal.com/2012/12/setting-up-intellij-idea-12-with-maven-actionbarsherlock-roboelectric-androidannotations/" rel="nofollow noreferrer">described here.</a></p> <p>The projects sources are set up <a href="https://i.imgur.com/TlnOBZf.png" rel="nofollow noreferrer">like shown in this screenshot.</a></p> <p><img src="https://i.stack.imgur.com/Vi8H3.png" alt="project sources"></p> <p>No matter how I make / rebuild the project, nothing ever shows up in gen/aa (and thus I can't reference CanvasActivity_.java) I ran mvn clean install from the project root, which fails with this stacktrace.</p> <pre><code>INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 4.363s [INFO] Finished at: Sat May 18 15:53:06 MDT 2013 [INFO] Final Memory: 11M/81M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project CanvasProto: Compilation failure: Compilation failure: [ERROR] /Users/matthewbbishop/Clients/proto/CanvasProto/src/main/java/com/airlocksoftware/CanvasProto/CanvasActivity.java:[6,38] cannot find symbol [ERROR] symbol : class R [ERROR] location: package com.airlocksoftware.CanvasProto [ERROR] /Users/matthewbbishop/Clients//proto/CanvasProto/src/main/java/com/airlocksoftware/CanvasProto/CanvasActivity.java:[11,12] package R does not exist [ERROR] /Users/matthewbbishop/Clients/proto/CanvasProto/src/main/java/com/airlocksoftware/CanvasProto/CanvasActivity.java:[14,15] package R does not exist [ERROR] error: Unexpected error.

If anyone has an idea of what to do, that would be amazing. Thanks!</p> <p>EDIT: here's the stub R.java generated by IntelliJ.</p> <pre><code>/*___Generated_by_IDEA___*/ package com.airlocksoftware.canvastest; /* This stub is for using by IDE only. It is NOT the R class actually packed into APK */ public final class R { } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
