    <p>I have an android library with the file structure below.</p> <pre><code>Android_Library ├── libs └── src ├── instrumentTest │   ├── assets │   └── java └── main ├── aidl ├── gen ├── java └── res </code></pre> <p>When I assemble the library with Gradle, the task runs successfully. However, when I try running a connectedCheck I get the following errors about the R file not being found:</p> <pre><code>:validateDebugSigning :packageDebug :assembleDebug :prepareTestDependencies :compileTestAidl :processTestTestManifest :generateTestBuildConfig :mergeTestAssets :compileTestRenderscript :mergeTestResources :processTestResources :compileTest Android_Library/src/instrumentTest/java/com/example/library/util/UtilTests.java:514: error: package R does not exist case R.plurals.time_days_ago: { ^ ... Note: Recompile with -Xlint:unchecked for details. 18 errors :compileTest FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':compileTest'. &gt; Compilation failed; see the compiler error output for details. * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. BUILD FAILED </code></pre> <p>I originally thought that it was a problem in the R resource generation, but then I would expect it to also fail when assembling.</p> <p>Edit:</p> <p>I have tried both having and R import statement (which I know is incorrect) and not having and R import statement. Both result in the same error.</p> <p>SOLVED:</p> <p>Thanks to @Xav's tip (below): I'm extracting a library from a larger project and attempting to build it on its own for modular testing.</p> <p>Changing the </p> <p><code>import com.example.app.R;</code> </p> <p>statements in the library files to </p> <p><code>com.example.library.R</code></p> <p>allows the connected check to run.</p> <p>(apparently the res files for both the main app and the library are the same).</p> <p>Additional notes:</p> <p>Since the switch statement takes in R id's the switch statement works when it compiles. However, I am still unsure of why <code>gradlew assemble</code> works with the incorrect <code>import</code> statements while <code>gradlew connectedCheck</code> fails.</p>

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.
