Hello

That's an excellent question. Not many know the pros and cons of USB debugging.

USB debugging is basically a way for an Android device to communicate with the Android SDK over a USB connection.

Leaving it in debugging mode has a downside. If you connect your mobile to your personal laptop, it's fine. Anyway it's you and your personal laptop.

But if you connect the device to a charging station with USB debugging ON, it's vulnerable to anyone who has access to the charging station. Exploiting the device data, malware, you name it. But a good news is, there's a safety Google has put here which requests user to accept the access request from the charging station. Hence it's safe.

Woah woah.. Hold on..

What if you lose your phone? What if someone can access it by connecting it to a PC or laptop? If the USB mode is ON, your private content is gone. Ummmm.. what do we do here?

Have Android Device Manager installed in your device. So when it gets lost you can remotely wipe your data off. If you don't know what an Android Device Manager is, search for Find My Device in your Google play store.

Honestly, why do you need it ON unless you're an Android developer? If your answer is to transfer files between mobile and a laptop/ PC - better switch it ON when you need and turn it OFF after you are done with the work. That's the safe way.

There are 2 ways you can connect your phone to laptop/pc.

1. Buy a compatible HDMI cable that can connect to a laptop. You might need 2 adapters, namely an OTG cable and an USB to HDMI cable. That way you can connect your phone to laptop and see what's going on and turn on USB debugging.
2. Turn off your phone by holding the power key for 10–15 seconds (depends on phone). After you are sure phone is turned off, boot into fastboot mode. There is a hardware key combination which can be different for every mobile. Generally it is Power + Volume down button hold for few seconds. After booting to fastboot mode connect to a PC which has adb and fastboot drivers installed and you will not need to enable USB debugging, you will be able to do everything from fastboot cmd that you want to do.
3. Or you could just get your display replaced if it's broken.

If you're an Android user troubleshooting issues or exploring advanced functionalities, you've likely cme across the term "USB Debugging" in forums or your phone's settings. Despite its technical sound, USB Debugging is a straightforward and valuable feature.

• USB Debugging Mode is a crucial setting for Android users, facilitating a direct connection between an Android device and a computer equipped with Android SDK (Software Development Kit). Activation is done by connecting the device to the computer via USB.

Why Enable USB Debugging Mode?

Enabling USB Debugging provides elevated access to your device, especially essential for tasks requiring system-level clearance, such as app development. It offers increased control over your device, allowing direct access through a computer with Android SDK. This access permits tasks like running terminal commands with ADB, beneficial for actions like restoring a bricked phone. Additionally, third-party tools like Wondershare TunesGo can leverage this mode for enhanced phone management. In essence, USB Debugging Mode serves as a powerful tool for adventurous Android users.

Taking an eg. Follow these steps to debug your Sony Xperia phones.

• Step 1. From your Home screen and go to Settings.
• Step 2. Under Settings, scroll down and open About Phone.

• Step 3. Under About phone, find Build Number and tap several times on it.

After tapping several times on it, you will get a message on your screen that "you are now a developer". That's it, you have successfully enabled the developer option on your Sony Xperia.

• Step 4: Back to Settings, you will see the Developer options menu, and select Developer options.
• Step 5: Slide the "USB debugging" to "On" and you're ready to use your device with developer tools.
• Step 6: Click USB debugging, you will see a messages "Allow USB Debugging" for allow a connection, click "OK".

Thanks.

Battery technology has improved especially with flagship models from leading manufacturers. Charge your phone when needed and do not obsess over it. Charge it to 100% if your day requires. Optionally for longest life li-ion batteries like to be kept between 40–80% charged. When the phone reads 100% the battery is actually less than that. Avoid high and low temperatures. Heat and cold will harm the battery faster than charging. Don’t leave it in hot or cold places. Above all use only a high grade ac adapter from a reputable manufacturer which has the proper protocol for your device not simply a “compatible” one like legacy USB 5V. Modern rapid chargers allow the phone to set the precise voltage as needed and are continually interacting with the phone’s built in charge controller. Not all USB Type C adapters can do this. Be observant. If the phone feels warmer than usual when charging then stop using that charger. It should get warm to the touch during the first half hour of charging but not hot and it should be cool after that.

Just dirty flash the ROM you are currently on.

And, FYI you don't need some “stubborn trojan killer” which itself sounds like some trojan. All these softwares are BS and you don't need them. No Cleaner Master, no CCleaner, no Floor Cleaner, no Toilet Cleaner, just nothing. These are nothing but adware and bloatwares. The android platform is itself sufficient in managing the RAM, if you know how to use it. Also, there's this thumb rule, Any app which claims to do 'trojan killing', 'battery saving', blah blah without asking any root access are definitely BS. They just care about earning money for displaying full screen ads on your device.

IMHO, yes. But I expect some flames from the people who say stuff like: don’t charge it over 80% or 90% or let it discharge below 20% or whatever numbers they invent. The charging circuitry is built into the device and the “charger” is simply a power supply. And I’m willing to assume that the engineers who designed the charging/power circuitry know more about optimizing battery lifespan & safety than I do. Those circuits are designed to stop charging the battery before it gets to an unsafe voltage or gets too hot. And to do about the same thing while discharging. It will shut the phone off before it discharges to an unsafe level. Will I get an extra 2 weeks lifetime out of the battery when it dies in 2–4 years if I stop charging at 80%? Darned if I know. And I have no way to test whether it’s a good idea or not. But I DO KNOW that the battery WILL die sometime in the forseeable future. I’ll replace either the battery or the phone when that happens. And until that happens, I’ll charge/discharge the battery on a schedule that works for ME. I’m NOT about to set my alarm for 3:30am every night to get up & plug in my phone to be sure it’s “fully” charged in the morning without going over 80%! I’m NOT a slave whose job is to supervise the care & feeding of my phone. My phone is a tool to serve ME.

The answer is no.

It is bit faster than the native run. The benefits of USB debugging is, it won't eat your system memory and it will give precise results than the virtual device. But these results depend upon the phone you use. If you use very old device,then it will be laggier.

The disadvantages are that your phone should have higher API(26,27) that is your Android phone should run on 8.0,8.1 (Oreo) to test the latest features. You have to manually test everything .

For eg creating a SMS message app,to test that notification works or not you need to send a SMS to your phone manually,but AVD has feature to send sms to Virtual device within itself.

So it all personal preference and application you create it

Thanks for reading :)

For Android 4.2 and newer, Developer options is hidden by default; use the following steps: On the device, go to Settings > About <device>. Tap the Build number seven times to make Settings > Developer options available. Then enable the USB Debugging option.

Is it the cable or the port? USB cables cost USD$1. There’s no excuse not to replace it.

I believe Android Studio communicates over ADB. As long as you aren’t needing access during the bootstrap, ADB provides a WiFi port. You will need to setup the phone to use wireless debugging prior to attempting it. That requires a USB cable the first time!

Z:\Drives>adb connect 192.168.50.162 
cannot connect to 192.168.50.162:5555: No connection could be made because the target machine actively refused it. (10061) 
 
<SEE IT DOESN'T WORK!> 
<INSERT CABLE HERE> 
 
Z:\Drives>adb tcpip 65000 
 
<DISCONNECT CABLE HERE> 
 
Z:\Drives>adb connect 192.168.50.162:65000 
connected to 192.168.50.162:65000 
 
Z:\Drives>adb shell 
lv517:/ $  
<SEE, A LINUX SHELL, NOT WINDOWS, I'M IN> 

<Note, in this demo, I previously changed the listening port to 65000. I believe the default listening port is 5555.>

f you have a rooted phone with a terminal application you can set this from the phone without the USB cable.

lv517:/ $ su 
lv517:/ # setprop service.adb.tcp.port 5555 
lv517:/ # stop adbd 
lv517:/ # start adbd 

<I’m setting the listening port back to 5555>

There should be a checkbox to tell Android Studio to connect over wifi if you provide the IP address and port.

1. In your phone, enable developer settings. Go to Settings > About Phone. Find the MIUI Version field and tap on it repeatedly 7 times. This will enable developer settings.
2. Then, go back to Settings, and find Additional Settings option. Tap on it and you'll find Developer Options over there.
3. In Developer Options, enable USB Debugging and Install Via USB.

That's it. Now connect your phone via USB, run your app and your device will be visible on the list of available devices. Select it and enjoy coding!

It sounds like you're asking if you can use your laptop charge cable to charge your phone without damaging the phones internal battery.

The answer is yes, you can use any USB type A to USB C cable on any device using a type C connector.

Where you need to be cautious is in the power brick(that plugs into the wall outlet or power bank) powering the cable. Your laptop may charge at 9 or 12 volts at 2+ amps, and your phone will most likely charge at 5 volts from 1–3 amps. Which means if you use the power brick intended for your laptop, you could damage the phones battery and possibly the phone by supplying a higher voltage to the phone. This does change with Quick Charge devices.

Essentially the phone will only draw what is required to charge it, power is not pushed to the device.

So, the short answer to your question is, yes the cable itself will work, the wall plug may not.

USB Debugging is a way for an Android device to communicate with the Android SDK (Software Developer Kit) over a USB connection. It allows an Android device to receive commands, files, and the like from the PC and allows the PC to pull crucial information like log files from the Android device. To enable it on any android device go to Settings > About <device>. Tap the Build number seven times to make Settings > Developer options available. Then enable the USB Debugging option.

Tip: You might also want to enable the Stay awake option, to prevent your Android device from sleeping while plugged into the USB port.

No. If ever there is any issue with making and breaking contacts then the engineers already thought of that. If you look closely at various plugs or circuit cards with sliding contacts, you may notice that sometimes a contact is shortened compared to others. This is to make sure that if necessary, certain circuits are powered up before others, usually the ground, then power then signals. Powering down can cause sparking so for circuit cards it is always a good idea to power off before changing these. In the case of USB the only conceivable danger is to electronics, not the battery, but power protection devices are already included in circuits because it is a consumer device.

Q:How can the Flutter app be debugged in Android Studio?

A: YES

like this

Debugger Running

You will need two things:

A android device (real one or virtual one from avd manager)

ADB driver for the device

Life Hack : universal driver for ALL devices :

After you install this plug in your device(or run virtual device) to your pc . Enable usb debugging under developer options.(if you cannot find developer options,tap the build number on the build number(in settings >about device) After enabling usb debugging , you can use run or debug options in android studio :)

The first triangle button is the run button and the button like a bug is the debug button.

Both button will build your code to a apk,run it and show debug output.you can use run,debug,logcat tabs on the bottom to see log output.

It typically looks like this..

Happy Coding and don't foget to upvote ;)

No. A powered hub is designed to only provide the 5 volts of USB so it really shouldn't be any different than plugging into a phone charger. Going higher than is specified on the amperage is, according to every electrical engineering expert I've asked, of no consequence either. You just need to have at least the specified amperage, otherwise the battery will charge very slowly.

In addition to just charging, you may be able to use a regular powered hub with a phone, via a USB OTG (On The Go) adapter (micro USB to USB Type A). You can use this setup to mount a desktop sized external hard drive that requires more power than your phone can provide. Using OTG combined with a USB to SATA adapter with external power, you can even see a regular SATA hard drive. I have done this and I can say that, at least in my case, it does work. Note: Android cannot natively see an NTFS file system, which is the default for Windows hard drives since Vista. To do so requires root privileges, which involves “rooting” your phone. This is not recommended for anyone that is not very knowledgeable with the inner workings of Android.
