In Android studio 2.0 after first app launch on emulator it seems that run process is attached to it. But if I connect device and want to test app, device chooser dialog is not showing up. I tried instant run, simple run, checked configurations (it's set to show chooser dialog), but all changes are made to emulator app.
How to launch app in device without turning off emulator and losing instant run "**connection**" with emulator ?
This behaviour is clearly a shortcoming that's going to be fixed in subsequent releases, there's an open issue at AOSP.
Right now I found two workarounds that don't require studio restart or killing the adb process:
Force close the app on the device you have the ongoing instant-run session. This way the session will be closed and you will be asked to choose the device after next run.
Press the "debug" button if you've pressed the "run" button before and vice versa. For some reason, changing from run to debug or from debug to run forces AS to close the instant run session.
Till the issue is solved, you can do this.
In the run menu, there is an option as 'Stop app'. Using that you can force stop your app. Running again you will get the device chooser option.
Your app will be present in your earlier device or emulator. You will just have to re-launch it. (If you do not want to run again on the earlier device.)
Go to Run>Edit Configurations > Deployment Target Options and uncheck "Use same device for future"
February 2018 answer:
Try to disable Instant run from the Settings, it worked for me on Android-studio v.3.0.1
Open the Settings or Preferences dialog: On Windows or Linux, select File > Settings from the menu bar. (On Mac OSX, select Android Studio > Preferences from the menu bar.)
Navigate to Build, Execution, Deployment > Instant Run.
Uncheck the box next to Restart activity on code changes.
Go to Task Manager and kill the adb.exe process.
This will detach the android studio with the running emulator.
You can then again run the program and you will see the device chooser.
Instant Run has nothing to do with emulator or devices, it will perform its action on whosoever you have selected.
Just restart your android studio and connect your device and launch app ; Dialog will appear.
When chooser dialog appears showing connected devices and emulators don't check "Use same device for future launches" to get this dialog every time you launch your app.
Also, if you want to run on all devices hold on SHIFT and click each and run.
Every time I click "run as an android application" in eclipse, the app only starts on my phone without asking if I want to start it on an emulator as well. I wish to have the app start on both my phone and an android emulator. How would I go about doing this?
Go to menu Window -> AVD Manager and run the emulator from there.
You can also change the run configuration so that it will prompt you for a device (in that dialog you can start the emulator) instead of just using any attached device.
On the Run menu select "Run configurations" then under Android Application find your project. Under the Target tab check the "Always prompt to pick device" option. After clicking Run, and in the future you should get a prompt asking you witch device you would like.
I write an android app using eclipse.
I have plugged in my new device (not rooted)
and I try to install my app on the device.
Unfortunately, eclipse shows the device is "unknown"
how can I fix this?
First of all, be sure your device has USB debugging set. This is in Settings => developer options.
If you can not access Android developer options, Go on Settings, About phone, and click 7 times on Build Number
Sometimes, Eclipse won't recognize device if you plug it in while Eclipse is open. 2 solution
Go in DDMS console, and in the Devices window, click on "View Menu" (arrow going down at the right), then reset ADB. It should freeze eclipse for few seconds, then your device will be recognized.
View Menu button is here
Restart Eclipse
I'm learing Android programming with Eclipse. I use to run my applications in either my mobile device or the emulator and it usally pop up a window where I can select which to run, and last time a checked the option to always run this device, so now I can only run it in my mobile device! I just wonder how I could get back the window to uncheck this option to be able to choose between them again? Thanks!
Go to eclipse Run Configurations select you applicaiton, then on the right on the Target tab select the Always prompt to pick device radio button.
I'm quite new to Android and have been using an AVD to debug my app so far. However, I want to start checking the media options and therfore need to start using my Android phone. How do I get Eclipse to load my app to my phone instead of my AVD?
First you need to enable USB debugging on your phone, then connect it to your computer via USB. Then eclipse should automatically start debugging on your phone instead of the AVD.
just for additional info,
If your apps is automatically run on emulator,
right click on the project, Run As -> Run Configuration,
then on the Run Configuration choose on the Manual.
after that, if you run your apps you will be prompted to chose where you want to run your apps, there will be listed all the available device and emulator.
I had the same problem, and have not been able to get Eclipse in Windows 7 to recognise the device. The device is correctly configured, Windows 7 recognises it on the USB port, and I edited the Run settings in Eclipse to prompt for a device, and it is just not there.
I ran it with the following steps:
Connect the device to the computer with USB.
Ensure the device is not locked (ie. timed out in the UI). I have to keep unlocking it while I'm working.
Wait for Windows to recognise the USB device, and when the autoplay menu comes up select Open device to view files. It should open up the file system in the device, in Explorer.
In Explorer go to the Eclipse workspace and find the apk file from the build (eg. MyFirstApp.apk)
Copy the apk file to the Downloads directory on the device
On the device, use the My Files app (or similar) to open the Downloads directory.
Click the downloaded file (My First App.apk) and Android offers to install it
Select install
The app is now in the installed Apps. Run it.
A second method is to mail the apk file to the device and then download and install it. (Credits to a post on SO which I can't find now).
A third method is to use DropBox. This requires installation of DropBox on the PC and on the device (from the play store) but once both are set up it runs very smoothly. Just share a DropBox folder between the two devices, and then drop the APK into that folder on the PC, and open it on the device. With this method you don't need a USB connection, and can also install the APK on multiple devices. It also assists the management of multiple development versions (by making a separate sub-folder for each version).
In Eclipse:
goto run menu -> run configuration.
right click on android application on the right side and click new.
fill the corresponding details like project name under the android tab.
then under the target tab.
select 'launch on all compatible devices and then select active devices from the drop down list'.
save the configuration and run it by either clicking run on the 'run' button on the bottom right side of the window or close the window and run again
You don't have to do anything really except prepare your phone to be able to run debug and usb apps :
http://developer.android.com/guide/developing/device.html
then simply launch your app from eclipse and your device will be used if you don't have a simulator running.
First of all, Enable USB debugging on your device.
On most devices running Android 3.2 or older, you can find the option under Settings > Applications > Development.
On Android 4.0 and newer, it's in Settings > Developer options.
In eclipse go to Run Configuration and select Always prompt to pick device
Some people may have the issue where your phone might not immediately get recognized by the computer as an emulator, especially if you're given the option to choose why your phone is connected to the computer on your phone. These options are:
charge only
Media device (MTP)
Camera file transfer (PTP)
Share mobile network
Install driver
Of these options, choose MTP and follow the instructions found in the quotes of other answers.
Hope this helps!

For those who are trying to find how to enable debugging on devices running Jelly Bean 4.2 (e.g Google Nexus), you have to go to Settings > Apps > About tablet and tap the text "Build number" 7 times slowly. Go back to the now available Settings > Developer options and check USB debugging as stated in previous posts.
Check to see if the Andriod Device is installed on PC. See steps below. The 'Other device' will change to 'Andriod Device' once the USB drive is installed. The browse path should be
\extras\google\usb_driver\
not the sub directories under it. Otherwise the installation will not find the package.
To install the Android USB driver on Windows 7 for the first time:
Connect your Android-powered device to your computer's USB port.
Right-click on Computer from your desktop or Windows Explorer, and select Manage.
Select Devices in the left pane.
Locate and expand Other device in the right pane.
Right-click the device name (such as Nexus S) and select Update Driver Software. This will launch the Hardware Update Wizard.
Select Browse my computer for driver software and click Next.
Click Browse and locate the USB driver folder. (The Google USB Driver is located in \extras\google\usb_driver.)
Click Next to install the driver.
connect your device to system and set you device debug mode on when you run your application Android Virtual Device AVD will select device there you will see your connected device select your mobile device and thats all refer this link to set your device debugging mode on
http://developer.android.com/training/basics/firstapp/running-app.html
The USB drivers in \extras\google\usb_driver didn't work for me.
However the official drivers from Samsung did:
http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
Note: I'm using a Samsung Galaxy S2 with Android 4.0 on Windows 7 64bit
What I did, by reading all of above answers and it worked as well: 7 deadly steps
Connect your android phone with the pc on which you are running eclipse/your map project.
Let it install all the necessary drivers.. When done, open your smart phone, go to: Settings > Applications > Development > USB debugging and enable it on by clicking on the check button at the right side.
Also, enable Settings > Unknowresoures
Come back to eclipse on your pc. Right click on the project/application, Run As > Run configurations... >Choose Device>Target Select your device Run.
Click on the Target tab from top. By default it is on the first tab Android
Choose the second radio button which says Launch on all compatible deivces/AVDs. Then click Apply at the bottom and afterwards, click Run.
Here you go, it will automatically install your application's .apk file into your smart phone and make it run over it., just like on emulator.
If you get it running, please help others too.
Thanks this helped. It was a little tricky getting the USB debugging option enabled on the Samsung G3 after the update.
See below
Instructions on Samsung G3 Jellybean
Settings
Click --> About the phone
Tap on the build number
“You are now 4 steps away from being a developer.” Keep tapping until it says “You are now a developer.”
Go back to Setting-->System --> Developer option: Enable USB Debugging
Step by step:
Connect your phone to computer via USB
Enable USB debugging on your phone: Settings -> Applications -> Development -> USB debugging
Change Run configuration in your Eclipse project:
right click -> Run As -> Run Configurations. In the Target tab choose Always prompt to pick device (or Manual). Then Apply, Run.
In the new window you should see your connected phone.
Yes! You can Debug Android Application While you are developing them follow these steps..
Make sure that you have PC suite of the mobile manufacturer. For Example:if you are using samsung you should have samsung kies
1.Enable USB debugging on your device:Settings > Applications > Development > USB debugging
2.Enable Unknownresources:Settings>Unknowresoures
3.Connect your device to PC
4.Select your Application Right click it: RunAS>Run configurations>Choose Device>Target Select your device Run.
You can also without using debugging cable.For that you need to install Airdroid in your device.After installing enter the link in your browser and Drag and Drop .apk file.
Happy Coding!
First you need to set your device to debugging mode. On Android 4.X that means as described in another answer in another question:
Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
Now scroll to the bottom and tap “About phone” or “About tablet”.
At the “About” screen, scroll to the bottom and tap on “Build number” seven times. [Note this is no joke]
Make sure you tap seven times. If you see a “Not need, you are already a developer!” message pop up, then you know you have done it correctly.
Done! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.
The next step is to connect your device to your computer via the USB cable.
The next step is to install a USB driver for it. On the official website you find a list with sources for drivers for phones from various different companies.
Eclipse now should give you the phone as a choice when you click on Run and it presents you possible device to launch.
In some case Eclpise will tell you Target Unknown which prevents you from using the device. If that's the case you might have to restart the phone. You might also have to check and recheckUSB debugging, till the phone asks you to allow your particular computer to do usb debugging.
