Where usb debugging in android?

On Android 4.1 and lower, the Developer options screen is available by default. On Android 4.2 and higher, you must enable this screen.

Note: On some devices, the Developer options screen might be located or named differently.

At the top of the Developer options screen, you can toggle the options on and off, as shown in figure 1. Keep this on. When off, most options are disabled except those that don't require communication between the device and your development computer.

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.

Enable USB debugging in the device system settings under Developer options. You can find this option in one of the following locations, depending on your Android version:

Tap Quick settings developer tiles to add selected developer options to your Quick Settings panel.

Once you select one or more of the available tiles, shown in figure 2, open 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.

Other general options include the following:

Debugging options provide ways to configure on-device debugging and to establish communication between the device and your development computer.

Enable USB debugging, as shown in figure 3, so your Android device can communicate with your development machine through Android Debug Bridge (adb). The Wait for Debugger option is unavailable until you use Select debug app to select the app to debug. If you enable Wait for Debugger, the selected app waits for the debugger to attach before it executes.

Other debugging options include the following:

Networking options provide ways to configure Wi-Fi and DHCP settings.

Tap Select USB Configuration to specify how you want the computer to identify the device. As shown in figure 5, you can configure devices for charging only, to transfer files (MTP), to transfer pictures (PTP), to use your mobile internet on the PC (RNDIS), or to transfer audio or MIDI files.

Tap Bluetooth AVRCP version and select the profile version you want to use to control the Bluetooth A/V equipment your device has access to.

Additionally, to fine-tune audio playback on the device, tap and set the following options:

The followng list describes other ways to configure Wi-Fi and DHCP setup:

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, as shown in 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.

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:

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. The choices are:

If you take screenshots in a simulated color space, they appear normal, as if you didn't change the color scheme.

Some other ways to leverage hardware-based options are the following:

Set Disable USB audio routing on to disable automatic routing to external audio devices connected to a computer through a USB port. Automatic routing can interfere with apps that are USB-aware.

In Android 11 and higher, when an application without RECORD_AUDIO permission uses UsbManager to request direct access to a USB audio device with audio capture capability (such as a USB headset), a warning message appears asking the user to confirm permission to use the device. The system ignores any "always use" option, so the user must acknowledge the warning and grant permission every time an app requests access. To avoid this behavior, your app should request the RECORD_AUDIO permission.

App options help you understand how your app operates on the target device.

Tap Background process limit to set the number of processes that can run in the background at one time. Possible settings are shown in figure 10.

• On the device, go to Settings > About .
• Tap the Build number seven times to make Settings > Developer options available.
• Then enable the USB Debugging option.

Enable USB debugging in the device system settings under Developer options. You can find this option in one of the following locations, depending on your Android version: Android 9 (API level 28) and higher: Settings > System > Advanced > Developer Options > USB debugging.

The steps to enable USB debugging depend on the version of Android running on the target device, as indicated in the following table:

If you are running Android 4.2.2 or later, you may see the following dialog when you connect your device to your PC running RAD Studio:

Click OK to allow USB debugging on your PC. If you accidentally click Cancel, disconnect your device from your PC and connect it back to make the dialog show up again on your device.

If your Android device is not correctly detected by RAD Studio or the system Device Manager, follow the steps above to verify that USB debugging is enabled.
