The Android {@sdkPlatformVersion} API 267is assigned an integer identifier — <strong>{@sdkPlatformApiLevel}</strong> — that is 268stored in the system itself. This identifier, called the "API Level", allows the 269system to correctly determine whether an application is compatible with 270the system, prior to installing the application. </p> 271 272<p>To use APIs introduced in Android {@sdkPlatformVersion} in your application, you need to 273set the proper value, "{@sdkPlatformApiLevel}", in the attributes of the <code><uses-sdk></code> 274element in your application's manifest. </p> 275 276<p>For more information about how to use API Level, see the <a 277href="{@docRoot}guide/topics/manifest/uses-sdk-element.html#ApiLevels">API Levels</a> document. </p> 278 279 280<h3 id="api-changes">API changes summary</h3> 281 282<p>The following is a summary of changes to the framework APIs.</p> 283 284<ul> 285<li>New {@code quickContactBadgeStyle*} attributes that let 286applications apply necessary styles to the {@link 287android.widget.QuickContactBadge} widget.</li> 288 289<li>Remove support for the {@link 290android.content.Intent#ACTION_CONFIGURATION_CHANGED} broadcast when declared as 291a filter in the manifest.

For example, {@code drawable-v4/} is a 335folder of drawable resources for API Level 4 (or higher) devices. This version 336matching did not work properly and has been fixed.</p> 337 338<h4>Contacts</h4> 339 340<p>The {@link android.content.Intent#ACTION_INSERT} Intent now returns the 341appropriate kind of URI when the request is made using the (now 342deprecated) {@link android.provider.Contacts} APIs.</p> 343 344<h4>Other Framework fixes</h4> 345 346<ul> 347<li>{@link android.app.Activity#getCallingPackage()} now properly reports the 348package name, rather than the process name.</li> 349</ul> 350 351 352<h3 id="api-diff">API differences report</h3> 353 354<p>For a detailed view of API changes in Android {@sdkPlatformVersion} (API Level {@sdkPlatformApiLevel}), as compared to 355API Level 5, see the <a 356href="{@docRoot}sdk/api_diff/{@sdkPlatformApiLevel}/changes.html">API 357Differences Report</a>.
