This is because we used a non-optimized layout to draw the view. So before diving into the code, lets take a moment and peek at the available tools inside the developer options. It To visualize the frame rendering time, we turned on Profile GPU Rendering (or Profile HWUI rendering in some Android versions) in Developer Options when recording the screen. Examples of such code may be the It is recommended to use a cache large enough to hold twice the screen in 8 bits. It just takes a few steps to disable HW overlays and make the system use GPU for rendering. The input handling stage of the pipeline measures how long the app Invalidation Save and categorize content based on your preferences. With this, you can recognize where overdrawing is occurring in your application. As a result, you can see a high Issue lengthy time may be the result of a few custom views that have some extremely The memory stores your app's images and data, among other things. Note that you might only see one or two rows of data in the output, depending on what is happening on your screen. Every Android developer begins their journey by enabling the developer mode on a device. Transitions. Its also worth noting that The colors in each bar represent the different stages in rendering the frame. adb shell dumpsys gfxinfo [PACKAGE_NAME] This command will output something similar to the following: we can see a row of frames. We use it for simple README files in our git repos or for writing blog posts. Each bar has colored segments indicating the relative time that each stage of the rendering pipeline takes, as shown in the screenshot below. I've tested while gaming and off gaming too. These will tell you how well your view is performing. Are there conventions to indicate a new item in a list? It should be adb shell dumpsys gfxinfo org.nativescript.profile > layout-profile.txt unless you didnt use profile for the app name when creating. It seems many people want the Skia OpenGL driver and they're changing it in developer options but it does not stick on a reboot so here is what you have to do. Profile GPU Rendering Graph Legend. Not all of this is available to a single app, so you may have to experiment a bit. Trailhead helps businesses build high-quality custom software solutions with predictable quality. While Profile GPU Rendering cannot tell you exactly what to fix in your code, it can hint at where you should start looking. It helped me to optimize my view rendering drastically. Profile GPU The Profile GPU Rendering tool gives you a quick visual representation of how much time it takes to render the frames of a UI window relative to the 16-ms-per-frame benchmark. After the small image is replaced by the large image, the. Panda Game Booster & GFX Tool for Battleground. to some property change of the animation. There is plenty of other information coming from the profiler that can be useful, but which I'm not covering in this post. Choose On screen as bars in the dialog box.

You may need to uninstall previous versions of the app. Seems like a good optimized rom, anyways this mod will not improve your benchmark but you can check the change in rendering speeds under developer options Profile hwui rendering section, and about disabling vsync i can make a separate version but note this ui / scrolling experience will be very bad with that but gaming will improve alot. Add code to the click handler of the LargeImages app to let your app sleep for two screen refreshes before switching the background to the smaller image. When you load the small image, you should see relatively short bars. resources. To shrink this bar, you can employ techniques such as: The Issue Commands segment represents the time it takes to issue all and clipping for each command before sending the command to the GPU. 3 Does Force GPU rendering drain battery? Each segment of each vertical bar displayed in the Profile GPU Rendering You'll see things like "Wireless Debugging," "Bug Report Shortcut," "Show Surface Updates," "Display Cutout," and "Profile HWUI Rendering." Many of these things mean nothing to the average user, but they're valuable to developers and power users. can have a specific size; others have a size that adapts to the size Also, since it is only colored bars it can be very difficult to interpret, especially if you're colorblind as I am. When you load the large image, there should be relatively tall bars, similar to the ones shown below. (You re-use this app in a later practical.).
