When hardware acceleration is enabled, the Android framework utilizes a new drawing model that This happens, for instance, when drawing a view into a bitmap for caching Is attached to a hardware accelerated window, it can still be drawn using a non-hardwareĪccelerated Canvas. Of View.isHardwareAccelerated() when possible. If you must do this check in your drawing code, use Returns true if the Canvas is hardware accelerated True if the View is attached to a hardware accelerated There are two different ways to check whether the application is hardware accelerated: This is particularly useful if yourĪpplication does a lot of custom drawing and not all operations are properly supported by the new It is sometimes useful for an application to know whether it is currently hardwareĪccelerated, especially for things such as custom views. Determine if a view is hardware accelerated See View layers for more information about their uses. View layers have other functions besides disabling hardware acceleration. Note: You currently cannot enable hardware acceleration at
If you need even more fine-grained control, you can enable hardware acceleration for a given The entire application but disables it for one activity: The following example enables hardware acceleration for The activity level, you can use the android:hardwareAccelerated attribute for To enable or disable hardware acceleration at If your application does not behave properly with hardware acceleration turned on globally, youĬan control it for individual activities as well. tag to enable hardware acceleration for your entire In your Android manifest file, add the following attribute to the You can control hardware acceleration at the following levels:

Hardware acceleration and how to work around them.Īnd Renderscript Control hardware acceleration The Support for drawing operations section describes known issues with With hardware acceleration turned on to find any problems. If your application performs custom drawing, test your application on actual hardware devices Remedy this, Android gives you the option to enable or disable hardware acceleration at multiple Usually manifest themselves as invisible elements, exceptions, or wrongly rendered pixels. Operations, turning it on might affect some of your custom views or drawing calls. However, because hardware acceleration is not supported for all of the 2D drawing
If your application uses only standard views andĭrawables, turning it on globally should not cause any adverse drawingĮffects. Hardware acceleration is enabled by default if your Target API level is >=14, but can alsoīe explicitly enabled. Hardware acceleration, your app will consume more RAM. Because of the increased resources required to enable Beginning in Android 3.0 (API level 11), the Android 2D rendering pipeline supports hardwareĪcceleration, meaning that all drawing operations that are performed on a
