<h3 id="studio_config">Configuring lint in Android Studio</h3>

<p>Android Studio allows you to enable or disable individual inspections and configure

project-global, directory-specific, and file-specific settings for {@code lint}.</p>

<h3 id="studio_config">Configuring Lint in Android Studio</h3>

<p>You can manage inspection profiles and configure inspection severity within Android Studio using

the <strong>File &gt; Settings &gt; Project Settings</strong> menu to open the <em>Inspections</em>

page with a list of the supported profiles and inspections.</p>

<p class="img-caption"><strong>Figure 3.</strong> Inspection Configuration</p> 

<p>The built-in Lint tool checks your code while you're using

Android Studio. You can view warnings and errors in two ways: </p>

<ul>

<li>As pop-up text in the Code Editor. When Lint finds a problem, it highlights

the problematic code in yellow, or underlines the code in red for more serious

issues.</li>

<li>In the Lint <em>Inspection Results</em> window after you select

<strong>Analyze</strong> &gt; <strong>Inspect Code</strong>.</li>

</ul>

<h4>Global preferences</h4>

<ol>

<li>To specify global project settings, select the project folder in the Project View and choose

<strong>Analyze &gt; Inspect Code</strong>.</li>

<li>Specify your inspection scope and profile, and click <b>OK</b>.</li>

<p>To set default Lint checks:</p>

<ol>

<li>In Android Studio, open your project.

</li>

<li>Select <strong>File</strong> &gt; <strong>Other Settings</strong> &gt;

  <strong>Default Settings</strong>.</li>

<li>In the <em>Default Preferences</em> dialog, select <strong>Editor</strong>

&gt; <strong>Inspections</strong>. </li>

<li>In the <strong>Profile</strong> field, select <strong>Default</strong> or

  <strong>Project Default</strong> to set the

  <a href="https://www.jetbrains.com/help/idea/2016.1/specify-inspection-scope-dialog.html?origin=old_help"

  class="external-link">scope</a> for Android Studio or just for this project,

  respectively. </li>

<li>Expand a category and change the Lint settings as needed.</li>

<p>You can select individual checks, or entire categories.</p>

<li>Click <strong>OK</strong>.</li>

</ol>

<p>The configured settings run the specified {@code lint} inspections. The {@code lint}

inspections are also run whenever you build and run your Android project and modules.</p>

<h4>Module and file-specific preferences</h4>

<p>To produce a list of Lint checks displayed in the <em>Inspection Results</em>

window:</p>

<ol>

<LI>Run the {@code lint} tool on your module by right-clicking on your module folder or file in the

Project View and selecting  <strong>Analyze &gt; Inspect Code</strong>. This displays the

{@code lint} inspection results

with a list of issues that {@code lint} detected in your module.</LI>

<li>From the <strong>Lint Warnings</strong> view, use the toolbar options to configure {@code lint}

preferences for individual modules and files, and set the issue display options.</li>

<li>In Android Studio, open your project

  and select a portion of your project that you want to test.</li>

<li>Select <strong>Analyze</strong> &gt; <strong>Inspect Code</strong>.</li>

<li>In the <em>Specify Inspection Scope </em>dialog, select the inspection

<a href="https://www.jetbrains.com/help/idea/2016.1/specify-inspection-scope-dialog.html?origin=old_help"

  class="external-link">scope</a> and profile. </li>

<p>The scope specifies the files you want to analyze, and the profile specifies

the Lint checks you’d like to perform.</p>

<li>If you want to change the Lint settings, click <strong>…</strong>. In the

<em>Inspections</em> dialog, optionally click <strong>Manage</strong> to define

a new profile, specify the Lint settings you want, and then click

<strong>OK</strong>.</li>

<p>In the <em>Inspections</em> dialog, you can search for a string

to find Lint checks. Note that changing Lint settings for a

profile in the <em>Inspections</em> dialog doesn’t change the default settings,

as described in the previous procedure. It does change the settings for profiles

displayed in the <em>Inspections</em> dialog, however.</p>

<li>Click <strong>OK</strong>.</li>

<p>The results appear in the <em>Inspection Results</em> window, organized by

category.</p>

</ol>

<h3 id="pref">Configuring the lint file</h3>

<p>You can specify your {@code lint} checking preferences in the <code>lint.xml</code> file.  If you

are creating this file manually, place it in the root directory of your Android project.  If you are
