Those of you who are not, Anti-aliasing is a technique used to soften sharp edges so that they appear less jagged when rendered. It is simply a technique of minimizing the distortion. The anti-aliasing settings can be changed on your Android device to increase the gaming graphics performance. This should only be done if you have a high-end Android device. For mid-range or low-end devices, changing the setting will impact the device performance as this requires more graphic power.
However, it incurs a performance cost for the graphics card and uses more video memory.
Configure on-device developer options
This will also drain your battery faster. You need to enable the Developer options to change this setting. Enabling this setting may result in your device getting heated up while playing graphic intensive games.
Make sure that your device has the right hardware before enabling anti-aliasing so that the device performance is not impacted. Do let us know in the comment section below.

Display cutouts allow you to create immersive, edge-to-edge experiences while still allowing space for important sensors on the front of devices. The following window manager code at PhoneWindowManager. SystemUI renders in the cutout area, and needs to determine where it can draw. By overriding onApplyWindowInsetsa view can determine where the cutout is and update its layout accordingly.
These methods outline how cutouts are handled in the status bar in all cases i. For more information, see the CDD. To implement display cutouts on your device, you must configure the following values for System UI. Defines the top margin for the quick settings panel. The clock and battery are displayed in the space above the panel.
Configure Unity Settings
Can optionally be taller than the cutout if desired. Total height of the quick-quick settings panel collapsed quick settings panel when the notification shade is expanded, including the space above the panel containing the clock. Values-land defaults this to dp, while the portrait default is dp. In most devices, this defaults to 24dp. When there is a cutout, set this value to the height of the cutout.
The height of the status bar in landscape. Cutouts are only supported on the short edges of the device, so this will always be an unaltered status bar height. When a cutout is present, keep this value at the default status bar height.
The path defining the shape of the cutout. This is a string parsable by android. PathParserand is how the size and shape of the cutout is defined to the system. Because physical cutouts have an exact pixel size, do not use the dp specifier when defining the path for a hardware notch. A boolean value that determines whether to draw the cutout path defined above in software.
Can be used to emulate a cutout, or to fill in a physical cutout to achieve anti-aliasing. Content and code samples on this page are subject to the licenses described in the Content License.
Overview Apps. Figure 1. Top center display cutout Android 9 supports the following types of cutouts: Top center: Cutout at the center of the top edge Top uncentered: Cutout may be in the corner or slightly off-center Bottom: Cutout at the bottom Dual: One cutout on top and one on the bottom Examples and source The following window manager code at PhoneWindowManager.
Requirements To ensure that apps are not negatively impacted by cutouts, you must ensure that: The status bar extends to at least the height of the cutout in portrait mode The cutout area must be letterboxed in fullscreen and landscape modes Your device can have up to one cutout on each short edge top and bottom.
Implementation To implement display cutouts on your device, you must configure the following values for System UI. The path is assumed to be specified in display coordinates with pixel units and in the display's native orientation, with the origin of the coordinate system at the center top of the display.Last month, I introduced some basic notions of Java 2D: that all 2D objects can be manipulated using AffineTransform s, that arbitrary paths can be constructed and shapes filled using GeneralPath s, and that text strings are drawn and operated on just like any other shape in Java 2D.
This month, I'll continue the discussion by presenting the solution to last month's aliasing problem. I'll also illustrate how to use one shape to clip another, and delve into the new image-manipulation capabilities provided by Java. Aliasing occurs when a signal in this case, a 2D graphics signal is sampled and quantized from a continuous space into a discretized space. Sampling is the process of reading a value from a continuously varying signal.
Quantization is the process by which these continuous sampled values are assigned a discrete value in the finite space represented by digital binary-based systems. Aliasing is a by-product of this quantization. Humans perceive this by-product visually as abrupt changes in color from pixel to pixel. Graphics professionals often refer to these jagged edges as jaggies. In general, aliasing is a bad thing. It leads to lower-quality signals of all kinds.
In fact, if you look closely at the examples in last month's columnespecially those with slanted and curved edges, you can see aliasing effects all the way back to Example Example01's lines are drawn parallel and perpendicular to the scan-line direction of the computer screen, so there are no quantization errors.
If you are not familiar with aliasing effects, you can refer to any decent graphics or signal processing textbook for much more in-depth information. If you are familiar with aliasing, but would like a quick refresher, see the Resources section for a link to "The Truth about Antialiasing" by Jonathan Knudsen. So, how do you handle aliasing? Java 2D lets you set one of several rendering hints to indicate that you would like for your 2D graphics to be drawn using antialiasing algorithms -- which smoothes the edges.
Note that I said hints : Whichever Java 2D implementation you're using, it is allowed to decide whether or not to follow the hint and carry out the antialiasing as requested. Let's compare the aliased output from last month's Example04 to some antialiased output, generated from Example You request antialiased rendering by calling Graphics2D.
Antialiasing and the other rendering hints are discussed in more detail in the Java 2D API javadoc documentation. So if aliasing is always bad, and antialiasing algorithms are available assuming your Java runtime environment supports the rendering hintthen why not just perform antialiasing calculations all the time?So, your Android game is running smoothly, but the edges of objects have those nasty little jagged edges. How can I make my Android games look even better?
With this trick, you can make the graphics in Android games silky smooth. In our test with the HTC Desire we came up with the idea to tickle its Snapdragon processor by running Spider-Man Unlimited with a few of the advanced settings enabled.
There are a number of devices on the market that have enough power for the following tip, and there will soon be even more with the upcoming influx of bit processors. Once there, scroll to the bottom of the settings menu and tap "about". Next tap more, and then tap the build number seven times. The developer options menu option should now be enabled. Go back to the original settings menu and tap the "Developer options" button.
Head to the bottom of the next page and tap advanced. Here is an example. Incidentally, the energy consumption is higher due to the additional processing required, so you may notice your battery life runs down quicker.
Also, this feature will not affect all Android games, only some of the more advanced ones. So there you have it. Thanks for the info, very usefull. I was quite annoyed at the jagged edges on Six Guns and this fixed it. And its one to note that you can access your developer options via app.
To the AndroidPIT homepage.Information about dates and alternatives can be found in the Oculus Go introduction. Submit a concept document for review as early in your Quest application development cycle as possible. This topic describes how to configure Unity settings to optimize the app performance and quality, and utilize Oculus features to ease the app development process in Unity.
We recommend that you perform these settings as outlined in this guide to meet the minimum technical requirements as defined by Oculus Store policies and guidelines. The Unity settings are project-specific and you need to configure these settings in a Unity project. Before you begin with the settings configuration, create a new Unity project or open the project in which you want to configure these settings.
Build settings let you set the target platform, configure build-related settings, and start the build process. Note : Select Development Build to test and debug the app.
For example, it bundles audio, input, graphics, rendering, physics, XR support, and many more. You can add basic product details that uniquely identifies your company and the app in Unity. When you build your Android app, the build tools use the package name as the package attribute value and add it in the AndroidManifest.
In Package Nameenter a unique package name. In Versiontype the version number that identifies the iteration. For subsequent iterations, the number must be greater than the previous version number. In Bundle Version Codeincrement the existing version code. This version is used internally to determine whether one version is more recent than another, with higher numbers indicating more recent versions. In Install Locationselect Automatic. To build a Virtual Reality VR app that provides an immersive and interactive user experience, you need to enable the VR support in Unity.
With the Unity version As a result, for these versions, the built-in XR platform integration is marked as deprecated. However, for version From the left navigation pane, under XR Plugin Managementclick Oculus to open and modify the default settings. There are a variety of options and settings that let you optimize rendering. You can define a specific set of Graphics APIs, choose color space property, or enable multithreaded rendering to optimize performance.
Expand Other Settings and under Renderingdo the following:.The Settings app on Android includes a screen called Developer options that lets you configure system behaviors that help you profile and debug your app performance.
For example, you can enable debugging over USB, capture a bug report, enable visual feedback for taps, flash window surfaces when they update, use the GPU for 2D graphics rendering, and more. On Android 4. To enable developer options, tap the Build Number option 7 times.
You can find this option in one of the following locations, depending on your Android version:. At the top of the Developer options screen, you can toggle the options on and off figure 1.
You probably want to keep this on. When off, most options are disabled except those that don't require communication between the device and your development computer. On Android 8. After you select one or more of the available tiles figure 2open the Quick Settings panel and tap the pencil to enter edit mode. Then, drag the developer tiles from the tiles pane onto the Quick settings panel, and tap the pencil again to exit edit mode.
Debugging options provide ways to configure on-device debugging, and to establish communication between the device and your development computer. The Wait for Debugger option is unavailable until you use Select debug app to select the app to debug. If you enable Wait for Debuggerthe selected app waits for the debugger to attach before it executes.
Addiitonally, to fine-tune the audio playback on the device, tap and set the following options:. Wireless display certification : Enables advanced configuration controls and settings for Wireless Display certification to the specifications set forth in the Wi-Fi Alliance Wi-Fi Display Specification. The certification applies to Android 4. For more information about logs, see Write and view logs with Logcat.
Aggressive Wi-Fi to cellular handover: When the signal is low, makes Wi-Fi more efficient in handing over the data connection to a cellular network. Input Figure 6. Pointer location. Enable Show taps to display taps when you touch the screen. A circle appears under your finger or stylus and follows you as you move around the screen. A tap works like a pointer when you Record a video on your device. Enable Pointer Location to show the pointer tap location on the device with cross-hairs.
A bar appears across the top of the screen to track the cross-hair coordinates figure 6. As you move the pointer, the coordinates in the bar track the cross-hair location and the pointer path draws on the screen. Enable Show Layout Bounds to show your app's clip bounds, margins, and other user interface constructions on the device, as shown in figure 7.
Hardware accelerated rendering options provide ways to optimize your app for its target hardware platforms by leveraging hardware-based options such as the GPU, hardware layers, and multisample anti-aliasing MSAA. Tap Simulate color space to change the color scheme of the entire device UI. The options refer to types of color blindness. Choices are Disabled no simulated color schemeMonochromacy black, white, and grayDeuteranomaly red-greenProtanomaly red-greenand Tritanomaly blue-yellow.
Protanomaly refers to red-green color blindness with weakness in red colors, and Deuteranomaly shown in figure 8 refers to red-green color blindness with weakness in green colors. Debug GPU overdraw: Displays color-coding on your device so you can visualize how how many times the same pixel has been drawn in the same frame.
The visualization shows where your app might be doing more rendering than necessary. For more information, see Visualize GPU overdraw. Debug non-rectangular clip operations: Turns off the clipping area on the canvas to create unusual non-rectangular canvas areas. Normally, the clipping area prevents drawing anything outside the bounds of the circular clipping area.
Disable HW overlays: Using the hardware overlay enables each app that displays something on the screen to use less processing power.It forces your phone to use 4x multisample anti-aliasing in OpenGL 2. However, enabling this setting can drain your smartphone's battery faster.
See Full Answer. How do you turn off developer mode? To disable and hide "Developer option" from settings menu. Go to Settings the main settings of your phone. Under the "Device" heading you will find "Apps". Move to the "All" apps tab. Scroll below to find and click on the app that says "Settings". Click on the button that says "Clear data".
Every Android smartphone and Android tablet contains a secret set of options : Android Developer Options. Android Developer Options allow you to enable debugging over USB, capture bug reports on to your Android device, and show CPU usage on screen to measure the impact of your software.
Debugging is the routine process of locating and removing computer program bugs, errors or abnormalities, which is methodically handled by software programmers via debugging tools. Debugging checks, detects and corrects errors or bugs to allow proper program operation according to set specifications. Programmers write computer programs in a language we call code. However, because no one is perfect, computer programmers sometimes make mistakes when writing their code. These mistakes are known as 'bugs'.
An important part of programming is testing your program and ' debugging ' which means removing the bugs. How do I get to developer options? First, you need to enable "Developer Options Menu". Click Menu button to enter into App drawer. Go to "Settings".
