		minSdkVersion 8

		<strong>
		renderscriptTargetApi 18
		renderscriptSupportModeEnabled true
		</strong>
		}
		}
		</pre>


		<p>The settings listed above control specific behavior in the Android build process:</p>

		<ul>
		<li>{@code renderscriptTargetApi} - Specifies the bytecode version to be generated. We
		recommend you set this value to the highest available API level and set
		{@code renderscriptSupportModeEnabled}
		to {@code true}. Valid values for this setting are any integer value
		from 11 to the most recently released API level. If your minimum SDK version specified in your
		application manifest is set to a different value, that value is ignored and the target value
		in the build file is used to set the minimum SDK version.</li>
		<li>{@code renderscriptSupportModeEnabled} - Specifies that the generated bytecode should fall
		back to a compatible version if the device it is running on does not support the target
		version.
		</li>
		<li>{@code buildToolsVersion} - The version of the Android SDK build tools to use. This value
		should be set to {@code 18.1.0} or higher. If this option is not specified, the highest
		installed build tools version is used. You should always set this value to ensure the
		consistency of builds across development machines with different configurations.</li>
