Configure on-device developer options | Android Developers
Android P brings a new app standby buckets to save battery life. So, we tell you Tap on “Build number” seven times to enable developer options. Advanced. It required Android JB+ and Developer Options enabled. How to take crash log from Developer Option: Spotlight U: Meet uTester Patryk!. The Settings app on Android includes a screen called Developer options that lets you configure system behaviors that help you profile and.

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. 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. User interface constructions Drawing options provide visual cues about the app's user interface and how it operates.
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. Other Drawing options include the following: Force RTL layout direction: Forces screen layout direction to be from right to left RTL or from left to right default. Sets the window animation playback speed so you can check its performance at different speeds.
A lower scale results in a faster speed. Sets the transition animation playback speed so you can check its performance at different speeds. Creates a secondary display as an overlay on the device. This is useful when supporting additional displays with the Presentation API. Hardware accelerated rendering Figure 8. Deuteranomaly color space 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.Android Developer Options Explained - Secret Settings on Android (Hindi - हिंदी)
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. Some other ways to leverage hardware-based options are the following: Show GPU view updates: Displays any onscreen element drawn with the GPU.
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. Using the hardware overlay enables each app that displays something on the screen to use less processing power.
Without the overlay, an app shares the video memory and has to constantly check for collision and clipping to render a proper image. The checking uses a lot of processing power. Automatic routing can interfere with apps that are USB-aware. Monitoring Monitoring options provide visual information about app performance, such as long thread and GPU operations. As of version 4. Some apps, however, haven't been updated to take advantage of this faster method of rendering graphics.
So if you have any apps whose graphics seem to be rendering slower than the rest of your apps, enable the "Force GPU rendering" option. This will make sure that all apps take advantage of Android's hardware acceleration feature, which should make the user experience a lot smoother in some cases.
Show CPU Usage This next option will come in handy if you've ever wondered what was going on behind the scenes on your Android device.
Enable the "Show CPU usage" toggle, then you'll instantly see an overlay on your screen that shows you all of the processes that are currently running.
These entries are ordered by their current CPU load, and your overall processor usage is shown as a bar graph at the top of the screen. The condensed graph at the top of your screen shows recent graphics performance history, while the bars across the bottom of your screen depict graphics performance on the fly. Higher spikes mean there was a heavy GPU load at that moment, so in general, this is a great way to see if an app is dropping frames or performing poorly from a graphics standpoint.
Background Process Limit If your "Process stats" menu was looking abysmal earlier, or if your phone just doesn't have much RAM, you might want to look into this last option.
Select "Limit background processes," then you can choose the amount of processes that are allowed to run in the background and eat up memory on your device.

For instance, you can set this to "2 processes at most," then only the current app and the two most recent background processes will be allowed to run, which should free up a lot of memory on your device. This feature allowed users to view two apps simultaneously by dividing the screen into two sections. However, to use split-screen mode, the app must support the feature, which isn't always the case. For example, the ESPN app doesn't support split screen, which is annoying especially you want to watch a game while also view an article.
In Developer options, you can change this by enabling "Force activities to be resizable. Now all apps will support split-screen mode, even if the developers decided against it. Do note that this isn't a foolproof method. Since you are using a feature not intended to be used by the app, it may act buggy or crash a few times. While this feature is much older than split screen mode, there are still many apps which don't support it.
Sure, this may affect much fewer users now as many OEMs continue to create phones without microSD supportbut installing apps on the SD card is still a useful way to conserve space. By enabling "Force Allow Apps on External" and restarting your device, you will no longer be blocked by app developers — any app can be installed on your microSD card.
However, this can break apps not designed for this method. Therefore, use trial and error to see which apps function correctly on the microSD card and which ones don't. If an app is in the frequent bucket, the system imposes stronger restrictions on its ability to run jobs and trigger alarms and also imposes a cap on high-priority FCM messages. If an app is in the rare bucket, the system imposes strict restrictions on its ability to run jobs, trigger alarms, and receive high-priority FCM messages.
The system imposes severe restrictions on these apps. However, there happens to be a catch to it. Nonetheless, users can manually also decide the Standby Bucket for each app, based on their liking. To do so, read on, as we show you how to manually set Standby Buckets for each app: Now, tap on Advanced and scroll all the way down.
Once here, scroll down to the very bottom.
