86. USB debugging: Allows your Android device to communicate via USB to your computer via the Android Debug Bridge (ADB). You can also revoke USB debugging authorizations: When you use a computer to debug over USB for the first time, you have to authorize it and set up a keypair. This setting revokes that.

Keep in mind though, sometimes there’s a good reason the developer of an app blocked the ability to install the app to an SD card. Some apps look for files in a specific place and the app won’t be able to find those files if it’s installed in an unexpected place. So when you install an app to your SD card using the 8775 Force allow apps on external 8776 setting, be prepared to uninstall it and reinstall it on the internal storage, if the app doesn’t work when installed on the SD card.

This isn 8767 t the kind of thing you 8767 d want enabled most of the time, but it can save you from having to install third-party floating CPU apps if you want to see CPU usage information for some reason.
From here, just back out to the main Settings menu again, and you'll find the new "Developer options" entry near the bottom, so go ahead and select it.
Tap the Build number field seven times to enable Developer Options. Tap a few times and you’ll see a toast notification with a countdown that reads “You are now X steps way from being a developer.”
If you’re using a high-end Android device and you play high-end, graphics-intensive games on it, the 8775 Force 9x MSAA 8776 ( multisample anti-aliasing ) setting in the Developer Options can help improve the images and graphics rendering in OpenGL ES games and certain other apps.
Before you can use the debugger and other tools, you need to enable USB debugging, which allows Android Studio and other SDK tools to recognize your device when connected via USB. To enable USB debugging, toggle the USB debugging option in the Developer Options menu. You can find this option in one of the following locations, depending on your Android version:
Anti-aliasing is a technique used to improve digital images by reducing jagged edges. Since in the real world, not everything operates in straight lines, this technique allows for digital objects to be display more realistically. Especially in gaming, this technique helps gamers escape from world, as the things created in the game look more like their real-world counterparts.
In Developer options, you can change this by enabling "Force activities to be resizable." Once activated, restart your device. 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.
Faking your GPS location can be useful in different situations. Maybe you want to prevent certain apps from determining where you really are, or you may want to check in someplace without actually going there. In any case, you can fake your GPS location using the 8775 Mock location app 8776 setting in the Developer options and a GPS spoofing app.
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 scheme), Monochromacy (black, white, and gray), Deuteranomaly (red-green), Protanomaly (red-green), and 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.
76. Show all ANRs: Makes every process show an 'App Not Responding' dialog if it hangs. Even if it is running in the background, which is useful if the app you are developing is interfering with another process, and you need to work out what is happening.
68. Mock locations: Hit the 'Allow Mock Locations' option, and you will be able to manually write location information. This is useful if you are developing an app that uses location information.
88. Wait for debugger: Not enabled unless you are set up to debug an app. When enabled it prevents that app from starting until the debugger is attached.
By default, the developer options in Android phones are hidden. This is because they’re designed for use by developers who want to test different things and make changes that may impact the phone’s performance. It’s not smart to go tinkering with the developer options without a specific purpose in mind and an understanding of what each option refers to. You have been warned.
67. Keep your phone awake: Check the 'Stay awake' opotion and the screen on your phone to stay on anytime and every time it is plugged in. Useful if you are working on Android development and find it annoying that the screen keeps timing out. But it won't do your screen any good in the medium term.
The problem comes into play if you need to plug your phone into an unfamiliar USB port—like a public charging station. Theoretically, someone who had access to that charging station could use USB debugging to access your device and steal private information from your device or copy some kind of malware onto it.
You can switch between viewing the services in use ( 8775 Show Services in Use 8775 ), which is the default setting we just mentioned, or viewing cached processes ( 8775 Show Cached Processes 8775 ). Cached processes are processes for apps that are not currently running in the foreground, meaning you’ve switched away from them.
To enable USB Debugging, you’ll need to jump into the Developer options menu, scroll down to the Debugging section, and toggle the “USB Debugging” slider.
