Android Studio can't detect my android POS Terminal [duplicate] - java
After installing android studio, I installed ADB as well. However, for some reason ADB doesn't detect my device. To make a note I think I have done all the basic stuff I found online, i.e.:
Set device in Developer mode and enable USB debugging
Cable works well (Android file transfer automatically opens when I connect the device)
Installed Java JDK 8
I have done 'adb kill-server', restarted my device and Mac but still not working
I'm using Android Studio 2.2 and running Mac OS X Sierra on my Laptop, and the android phone is running Android 5.0.1 (on an LG Phone)
NB: I have tried the other solutions on stack overflow but thats not the problem.
ADB (is installed) and works from the command line, but when I run :
'adb usb' command, it says 'error: no devices/emulators found'
'adb devices' command, it prints 'List of devices attached' with an empty line beneath.
I believe this is a specific issue and the general solutions to install ADB or restart doesn't work here as I have tried all that.
I have removed and reinstalled android studio, still not working.
I have removed and reinstalled adb and adb & fastboot, still not working.
I have restarted my device, disabled and re-enabled developer mode, still not working.
Obviously, I have unplugged and plugged the cable back in several times, still not working (only Android File Transfer keeps coming up)
Just in case, I have rooted my device, could that be the problem or that doesn't matter?
You basically need to set the USB mode to PTP mode instead of Media Transfer Protocol (MTP) mode.
When I connected the device via USB the USB icon and Debugging Mode Icon appeared on the status bar on the device.
If you open control center by swiping down from the top, you should see a "Media device MTP" - Tap for more USB options. Tap it and switch the mode to "Send Images (PTP)" mode and it should ask you if you want to enable USB debugging. Enable it and the device should be recognized by ADB and Android Studio now.
I just clean installed my MBP and encountered the same issue. I tried the things suggested here but nothing worked.
What I had to do to fix it was "Revoke USB debugging authorizations" from the Developer options.
Once I did that, it offered up the usual "did you want to allow debugging on this device" option, and everything was back to normal.
Go to developer options and enable USB Debugging:
Settings > More > Developer Options > Debugging > USB Debugging.
Note:
You have to enable developer mode on your phone first
I was already in USB debugging enabled state and also had switched USB configuration to PTP. It was still in always charging mode no matter what I do. I had even reinstalled all Android related stuff, tried on multiple devices to find a fix. Finally what worked for me was getting a new cable.
I had posted a question here (now marked as duplicate) since these answers didn't suffice my situation.
If anyone is still having problems, consider the cable you are using. Not all USB cables are created equal! Some will charge but not allow data transfer. See this post.
In my case, the problem was that developer mode went away after doing an Android system update. Double-check developer mode and USB debugging settings.
I tried everything on my MBP but failed to fix the issue. Finally, with the least expectation, I reset my MBP's SMC, and everything is back to normal!!!

Make sure no other services are trying to access the device via adb. For me, I was using chrome inspect for checking the network requests. When I closed that window studio automatically detected the device.
Yeah, this one's tricky! Enabling Developer Options on your device is just a half of the procedure. Now you need to go to:
Settings > System > Advanced > Developer Options > Revoke USB Debugging Authorizations
Also check the cable - some are just for charging, no data can pass trough.
Please use the correct USB-C cable that came with the phone/device. Also, this can happen if incompatible converter is used, but this is less likely.
Add “platform-tools” to your PATH variable by invoking the following in the Terminal (make sure to change the file path to reflect where you placed the folder “platform-tools” on your system):
echo 'export PATH=$PATH:~/SDKs/android-sdk-macosx/platform-tools/' >> ~/.bash_profile
Execute the following command to reload your bash profile (this applies the change to the PATH variable):
source ~/.bash_profile
Note: The PATH variable is the search path for commands. It is a list of directories, each separated by a colon, in which the shell looks for commands. To see what values are currently in your PATH variable, use the following:
echo $PATH
adb devices
It should return something like this (if you have one Android device attached):
List of devices attached
212304114c28b9e device
I tried all of the above and the only thing that helped me was
to change the USB port and also change the data cable.
I was actually using a converter from USB type to C type at the connecting end to mac port
I think the converter corrupted the mac port. This was for Macbook Pro
update
I also tried doing a soft reset of the SMC and worked like a charm after that.
I face the same problem with my One+ device and after trying everything mentioned above , still was not able to conenct . But finally after enabling "OTG storage" option in System , it works.
it might be different for different custom devices . so ultimately you have to look for an option which gives a notification in device when you conenct and disconenct your device with system.
This happened to me on initial setup. I noticed that Gradle sync was taking a long time, so I waited for it to fully sync, then my device magically became available!
ADB was detecting the device but AS wasn't, I went to Preferences > Build, Execut

Could not open Selected VM debug port (8700). Make sure you do not have another instance of DDM
I have tried every tip to solve this problem but it simply do not work. The problem accured after update of android studio to 3.01 + gradle. I have older dependencies and gradle + android studio on my laptop and it works without any problem. I just want get access to Android device monitor to look up into my sqlite database files. I tried simply kill, restart adb process, use different port then 8701, edit host file but without any progress into resolving this issue. Everything except Device monitor works fine. I am able to launch application on emulator and actual phone. Maybe someone met this issue after updating program and have some sort of magic solution.
Found a problem earlier but forgot to post it here. It appears to be a issue with platform level 24 and above. You need to work on level 23 in order to use android device monitor.
OnePlus One not found in Android Studio on Mac
I have a strange problem while developing in Android Studio on mac and i am using OnePlus one. While debugging if a call come on my mobile adb disconnect my device and don't show it again. Help me to solve this permanently. Only solution that i have found and which works is in following step: Restart mac disconnect cable from mac and OnePlus One Kill adb server start adb server Revoke developer certificate and turn off developers option. restart onePlus One Turn on OnePlusOne and connect device with mac Open Android Studio Enable developer option and then enable debugging option After I follow these steps, fingerprint dialog show and once I allow that dialog, device starts to show. This process is time consuming. I am facing this problem on mac.
Putting the phone in airplane mode seems to have temporarily fixed the issue for me. I still need to look at the logs and figure out what is wrong, but there seems to be a bug in the latest 5.x updates for the OPO.
Are you using EasyTether? If yes, you can disable it by using the following command: sudo kextunload /System/Library/Extensions/EasyTetherUSBEthernet.kext If that does not work, open System Information utility and check your device manufacturer ID (Vendor ID). Copy that and paste it into your adb usb config by using echo 0x9d17 >> ~/.android/adb_usb.ini Then restart your macbook and mobile phone and try if it works.
There are several reasons your phone may not be getting detected properly, in my case it showed my phone in My Computers, and also asked me if I allowed my PC to debug on my phone. Yet it wasn't showing the phone in the android studio adb devices drop down menu. All I did was, go to Tools>Android>Enable ADB Integration and it found my device. This is once I had installed my OPX driver that shows as a disk in My Computers and also Samsung USB driver. I'm talking about Windows here but the solution applies to Android Studio on any platform. So thought I should share.
Android Processing programming will not run application on device. How do I fix this?
I'm currently working with Processing, and I would like to code an android app. I have succeeded in being able to launch may application in the android emulator, but I am not able to get it to launch on my Galaxy 2.0 tab. I click run device, but every time I do I get a message at the end that says "waiting for device to become available". I'm thinking that I may need to point Processing to my android tablet somehow. Any ideas as to what I'm doing wrong. I'm on Windows 7.
It means your device is not being detected in the eclipse debugger tool. Did you check in Tab "Developer Options", make sure USB debugging is enabled. please refer other links you may get answer. Click here Device not detected in Eclipse when connected with USB cable
Adb.exe (Android Debug Bridge) Can't Install .apk
Whenever I use the adb to install an Android application on either my emulator or device, it says "Failed to install *.apk on device timeout. I tried every solution that was offered in identical questions: I changed the ADB connection timeout from 5000 --> 60000 I restarted ADB I restarted the computer. However, none of these methods seem to work. I'm running the ADB on Windows Vista 32 bit. Is Windows Vista the problem? ADB can install apks when run on my Windows 7 computer. The only reason I can't use Windows 7 is because its processor is too slow (the emulator runs at 2 fps) By the way, when I used the 'adb devices' command in the command line, it seems that the ADB recognizes my phone or emulator. For some reason, it can't install an .apk or push or pull files.
This is something I've experienced before. It tends to occur (for me) when I'm using a generic USB cable or am not plugged in properly. There really are many things that could be wrong. For example, you may need to restart your device, you may need to try a different USB port. These kinds of thing don't have a definitive solution.
Why can't OSX detect android Galaxy S for USB debugging?
I searched for similar questions on this issue but found none related to Mac OSX. Situation: Trying to test android apps on a Galaxy S (Details below) but Mac is not detecting the device. Tried all the things below and have wondered whether this might be a driver issue (which I've heard things about for Samsung USB debugging). Questions: 1) Are samsung drivers required for android USB debugging? 2) And are they available for Mac OSX? 3) Any other reasons OSX might not detect device for usb debugging? Things I tried: Enabled USB Debugging # Settings >> Applications >> Development >> USB Debugging Enabled Tethering # Settings >> Wireless and network >> Tethering >> USB Tethering Set Tethered mode # Settings >> USB connection >> Tethered mode Attempt to detect devices via ./adb devices (from platform tools dir) Verified that "Unknown Sources" is checked # Settings >> Applications >> Unknown Sources Verified that device is connected to Mac Restarted phone Restarted mac Added various device / product ids to adb_usb.ini Did ./android update adb (which does adb kill-server / start-server) Using: Samsung Galaxy S (4G) with Sprint Mac OSX 10.6.8 Eclipse Classic 3.7.1
Have you tried connecting the phone using a powered USB hub? I haven't tried it yet but found this blog post that suggests it may help for Samsung Galaxy devices. http://esausilva.com/2010/10/02/how-to-set-up-adb-android-debug-bridge-in-mac-osx/
Go to Tethering select and then deselct USB Tethering and you are done. this worked like a charm.
make sure that you plugin your device in the usb ports on the mac itself, not on the keyboard usb-ports.
Well I tried all kind of stuff for a phone that was working yesterday but not today. Finally replacing the cable between the phone and my mac solved the issue.
USB driver problems happens under Windows. For MacOS, I had nothing to do : ADB found my device. You don't need tethering : it's for sharing an Internet connection. USB Debugging is needed. Also make sure you authorize your Galaxy to use Unknown sources (# Applications -> Unknown sources (it's a check box)).
This happens all the time with lots of phones. Two things that have worked for me are (1) type "adb kill-server" at the command line, or (2) try another cable.
This may sound crazy, but I tried every suggestion on this page except what finally worked: Use the Samsung USB cable that comes with the S7 (my S6 cable worked too) Every other USB cable I tried did not work. I don't know exactly why (USB 2 vs 3?), but that is what worked for me. Of course, make sure USB debugging is turned on, and yada yada yada, but I did all that and still NOTHING. The moment I plugged in the USB cable that came with my S7 I got the RSA fingerprint message, and confirmed USB debugging, and the device showed up in Android Studio when I clicked Run. HTH --jsp
Go to Settings Wireless and Networks USB Utilities Detach the USB cable Select Connect Storage To PC Reconnect your USB cable to your phone. Source: Galaxy S II Forums - Help, Mac won't recognize my galaxy S 2
This is what worked for me on Samsung Duos: Go to settings > More > About device(at the bottom) On that about device screen go to bottom and touch 6 times on the "Build number" (un till it doesn't display any notice) Then visit again to settings > More and it will display developer options before the about device. Click on developer options and tweak options as you need. Now on the mac, click on run button in android studio, it will display the connected device.

I spent a night fighting this problem with my Doogee DG350, which runs the Chinese MTK chipset which has issues with USB on OS X. I found the solution was to run ADB in TCP/IP mode and then connect wirelessly: adb tcpip 5555 adb connect 192.168.1.10:5555 adb devices it's actually a bonus, cos you can dispense with the USB cable and debug wirelessly. Not looking back
None of these things worked for me. I'm running 4.4.2 on an LG VS450PP, trying to connect to a Mac laptop running OS X 10.10.5. Neither MTP nor PTP worked at all, even after following all the suggestions listed here and elsewhere on SO. I only got the RSA message when I chose the Internet option from the USB settings (and then I chose Ethernet). After that, it was golden.
The connection via tcpip has a potential to work. However, the port 5555 is probably not available. I know this can work because I have an app on my Android called "Synctunes Wireless" which syncs' my itunes on my desktop wirelessly via tcpip and using port 4444. So I used the ip address and this port showing on this app and I can see this device in my Eclipse. Only thing is that the device type is unknown so the "OK" button is still disabled. So this has potential to work. Just have to find the right port number or maybe something else that is missing.
If anyone still has this problem and looking for a solution, what helped me is to install Smart Switch app. After that my Samsung device finally showed up
So i did some research because the same thing happened to me. If the simple solution doesn't work you should check if you installed knox when you first launch your phone. If you did install knox the only way for you to activate usb debugging would be to reset your phone back to factory config in order to deactivate knox (aka not installing it again), apparently you don't have the option to unistall knox on recent phones.
I know it is ridiculous but do make sure your phone's got a SIM card!
To activate the USB debugging on Samsung Galaxy S go to Menu -> Settings -> Applications -> Development -> Check "USB debugging".
