I moved my Android project to a laptop and now I get this when I hit Debug. Sounds like this is a bug? This shouldn't happen via Eclipse as far as I know.
Re-installation failed due to different application signatures.
The weirdest thing is this happened after I upgraded sdk/adt and Eclipse to support SDK 2.2 It was working fine earlier, and now it doesn't, so it might be a bug.
It happens because keystores on your laptop and original pc are different. it's called debug.keystrore
and located in %USER_HOME%/.android/ folder. TO be more specific it happens because eclipse tries to push apk with reinstall key. So you have two options
Share debug.keystore between various development pc's
Manually uninstall your apk from device ( using adb )
I also got the same problem and fixed it. you should do the following to fix it,
Uninstall the application from your mobile if you load it
already.
To uninstall goto settings->application->manage application.
Run the application again and choose the mobile
Hope this will help you
After you copy debug.keystore to your PC, you need to rebuild project on PC.
I had the same issue using the Droid emulator. I solved it by uninstalling the package from the application settings in the emulator as you would a normal device. On the next run, it reinstalled and the error went away.
I got the same problem and fixed it by just wiping the user data on the emulator. My guess is that the emulator keeps the project installed unless you wipe the data, so if your new project doesn't match some internal parameters it doesn't like it and won't reinstall it.
I also had the same problem and fixed it by uninstalling the app and reinstall it again.
ah i think i found your answer:
Why does the app signature change in Android after a classpath change?
its changed if you change the classpath
After searching and checking the phone, i came to know that i am currently developing 2nd version of this application which is already downloaded from android market in my phone, now as this app is signed and having different signatures this is throwing the above error.
Now, to resolve this issue, i had just uninstalled the app from mobile and run/install the application again.
I had the same issue with the emulator and i ran the command "adb uninstall TheNameOfPackage". Of course you must first go to the directory where the adb.exe has been installed, usually C:\Program Files\Android\android-sdk\platform-tools, and then run the above command.
For me after I copied all of my keystore files from my machine at home, I had to do a Project->clean. After that it worked perfectly.
When i tried to uninstall the application from my device after this issue occurs, i cannot able to find the app in my device. I don know where it gone. Then i uninstalled using adb,
adb -d uninstall <app package name>
This is the answer who are facing the issue similar to my problem.
I had the same issue.
To fix it I uninstalled the old .apk of the project from my device.
Go to device/emulator Settings -> Apps, find your app and uninstall it.
Or
In Android Studio open tab "Gradle" (on the right side), open:
appName
..appName
...Tasks
....install
.....uninstallAll
and click twice on this task to execute it.
Important note:
If you still get this error after uninstalling, try to Build->Clean Project.
If you still get this error, even if in your device Settings->Apps list you have no this app already, try to Build->Clean Project

I created a new empty project, switched platform to Android and started Build and Run. But when it comes to "Copying APK File to device" it just freezes and I have to restart Unity.
I installed Android SDK & NDK tools just before that (through Unity Hub). Android Build Support was installed by me manually a while ago so it was visible as installed in Add Modules window. I did not do any changes to the project. The most interesting thing is that the apk is built in my Builds folder. Not sure if it works though.
I am using Unity 2019.1.0f2. The device Android version is 9.0 (API level 28) and the minimum API set in Player is 16, so the problem should not be with API.
Does anyone know possible reasons for it?
Try to turn off the following setting on your android device.
Settings -> Developer options -> Monitor apps installed by ADB
This setting(if turned on) will ask a verrification if you want to install the app. It feels like this cuts off the connection with unity which causes it to get stuck.
Unplugging and replugging the device seems to work aswell. In case of big projects this is anoying tho since if you are to quick it will just say it lost connection and it will ask if you want to reconnect, which in turn causes the same problem.
This is the only answer that worked for me:
https://answers.unity.com/questions/1248123/build-run-apk-freezes-on-pushing-content-only-one.html
In short, Player settings -> Publishing settings -> Split application binary
First of I would ask you on what computer did you run this on? (performance wise)
Second you can just copy the .apk file to the phone and install it there. If you got to where it prompts for copying to android your apk file is fine and built.
I've read every StackOverflow that I could find on this issue, but I still can't work it out.
I'm trying to deploy an app to actual device (NOT emulator). But I receive the following error when i try to build:
Severity Code Description Project File Line
Error Error : DEP6100 : The following unexpected error occurred during bootstrapping stage 'Connecting to the device '30F105C9-681E-420b-A277-7C086EAD8A4E'.':

It's worth mentioning that I went from Windows 7 to Windows 10. It's also worth mentioning that my computer was missing the IpOverUsbSvc.exe (not just the registry post, but the actual service was missing). Couldn't find any way to get this back so, so my colleague sent over the .exe and the DLLs and I placed it in it's location. And the service is now running and no longer gives any errors. My device is recognized by the PC, it's running Windows 10 Mobile (but I've also tried with a device running Windows 8.1).
Specs on PC:
Windows 10 Pro (Build 10240)
Using Visual Studio 2015
UWP Tools
Any suggestions to fix my nightmare? Thanks!
Steps that helped me. I have windows 10 mobile build 10581 (and now 10586) installed on phone
Turn off Developer mode on your phone.
Deploy app (UWP or SL) by VS2015 -> Error.
Turn on Developer mode on your phone.
Deploy app (UWP or SL) by VS2015 -> Working.
If you change another device or re-connect you must close VS2015, re-launch and do again!
Finally managed to find a solution to this illusive bug.
It seems that if I didn't have the Windows Phone 8.1 Tools installed I couldn't build to an ARM device (not even Windows 10 Mobile).
So my step to solve this was:
Go to Control Panel -> Programs and Features -> Microsoft Visual Studio ... 2015 -> Modify. And then select the Windows Phone 8.1 Tools.
Pretty pissed that one can't get a reasonable error message when things like this is missing.
I had this issue after updating my device to win10 ver:10.0.10581.0. I tried many things but finally after installing latest sdk and emulators i got it working. You may try installing from this page sdk and emulator:
https://dev.windows.com/en-us/downloads/windows-10-developer-preview
Somehow the new emulators were not visible in vs, they got visible after few restarts and then on device debugging started to work.
But one problem still remain from me that vs crashes after ending debug session with device.
desktop-->my computer--> right click--> management--> service--> start the service Windows Phone IP over USB Transport (IpOverUsbSvc) although maybe the starttype is set as automatic
Seems like there are many issues causing the same error message.
This one worked for me Windows Phone deploy Issue
Essentially you need to remove/uninstall the device from Windows. Then after unplugging and plugging back in, the device and drivers are reinstalled.
I tried many of the suggested solutions to no avail.
After changing the USB-C cable from a USB 3.1 port to a USB 2.0 port on my computer, the error goes away. YMMV
I see it is quite an old post...but I still get this problem. In my case, this happened after I deployed to a second phone I had for testing. After that, VS 2017 now only wants to deploy to that phone and not to the other phone no more. If I start another project, the other phone is recognized and deployable to (listed as device under debug).
Restarting system fixes this...
Also, if I add another project as reference (like a background task) to my project, I will loose the ability to select the devices and emulators under debug. VS 2017 simply then seems to deploy to the last device selected...(really no clue what this is). I have not been able to get the selection of emulators and devices back yet on this one. I only will have the "Start" and "Download new emulators" options. I think this has to do with the fact that VS maybe doesn't know the type (like arm/86/64) of the reference project because it is not set (not needed as this defies the purpose of referencing a project for dynamic references and not the compiled device specific file...)
Hope it helps someone ....
I uninstalled the existing version of the app in device and re-ran it and it worked for me
I got that error for a really simple reason...just opened a new solution I downloaded from GitHub, pressed F5, and got it!
I had left my build configuration in the default "Debug - ARM" setting, when I changed to "Debug - x64" it worked fine!
(Just adding another reason for completeness, not likely to affect your case!)
In case it's helpful for others... I got: DEP6701 bootstrapping failed ... access denied.
Thanks to comments here, I only dev-locked then dev-unlocked my phone (was originally dev-unlocked). Totally works now (took some time installing missing frameworks at first). All good.
Thanks
One more thing could be tried.
Uninstall the existing app if any and then deploy from Visual Studio.
Try on another usb port. It worked
I am totally new to Cordova, but now I have installed Cordova with NPM and installed Android SDK and set up an AVD which seems to work perfectly, until I want to emulate my project. Where the actual app for some reason is not loaded into the emulator.
The following action is done:
marvin:HelloWorld$ cordova -d emulate android
cordova library for "android" already exists. No need to download. Continuing.
Wrote out Android application name to "HelloWorld"
Wrote out Android package name to "com.example.hello"
Calling plugman.prepare for platform "android"
Preparing android project...
Processing configuration changes for plugins.
Iterating over installed plugins: []
Writing out cordova_plugins.js...
Running on emulator for platform "android" via command ""/home/marvin/Development/projects/HelloWorld/platforms/android/cordova/run" --emulator" (output to follow)...
Then it start Android emulator up, but the app is not there. Does anybody have a suggestion to fix this issue, so I am capable of actually testing in my emulator?
Thank you in advance.
I just had the same problem, and I was missing PATH to platform-tools in android sdk folder, after I added it everything was in place.
I had the same problem as well; I could run the cordova emulate android command just fine, and the emulator would eventually start up and function, however, the test app was never installed on the device. I was not getting any errors from the Cordova CLI or the console or anything.
I found that there is a bug report about this issue here: https://issues.apache.org/jira/browse/CB-4285
Two solutions have been found for this issue:
1. Make sure you are using an Oracle JDK and not an IBM JDK, and
2. Make sure the AVD that emulate starts up has a min-target-sdk set to API 10 (Android 2.3.3) or higher. (This was my problem.)
Sometimes it works deleting the previously installed version of the app in the emulator. For this you could also launch it with the option "Wipe user data" checked.
Just for the record, none of the other solutions worked for me.
I had the same issue. Following solved it for me.
Make sure that API level of your AVD is greater than minSdkVersion specified in config.xml specified in your cordova app.
If anyone still having this issue:
I had a same problem with device being offline.
if ddms is running it looks after connected devices.
adb kill server
and than run ddms
Also make sure your app id doesn't begin with a number or any other character like "_". For example, if your app id is com.4company.MyApp or com._company.MyApp it just won't load on the emulator. The first one is because Java doesn't allow names beginning with a number, and the second one I guess it's a Cordova thing.
You should also use adb logcat to show the emulator errors on the command line.
For me, the app was not starting up because I had a second emulator running in the background. Uninstalling bluestacks (android emulator for windows) fixed the issue in my case. Running "adb logcat" should tell you if you have multiple emulators running.
I just had the same problem, and It was my emulator device that was with the API 15. Just updated to API 17 and the problem solved.
I thank you all for reading this lengthy question. It's really important and I will appreciate it if you can assist me :)
The problem -------
I am have been using the Windows 7.1 SDK for about two months now. The emulator has worked without any problem so far. However, today, it began displaying this error (The saved state (Name of File).dess is corrupt. Please delete the corrupted saved state file and then retry). I had not made any significant changes to my project code, or moved any files. I had just added some Visual State animations for a button.
As it suggested, I went ahead to delete the file. I then started debugging again. However, the emulator now opened and displayed the message (Windows Phone Emulator is doing a complete OS reboot). This message was displayed for a very long time. I closed the emulator and project. Since then, I have been unable to use the emulator. I am able to code normally in Visual Studio, but I cannot test my application.
What I have tried ------
I read up on this issue and found many others who faced the same emulator issue. Following their suggestions, I have run one repair of the Windows Phone SDK 7.1. I have also tried uninstalling and then re-installing the SDK 7.1 once.
System Specifications -----
I am using Visual Studio Express 2010 for Windows Phone (Windows 7 64 bit)
I have downloaded the Windows Phone SDK 7.1 from this link: http://go.microsoft.com/fwlink/?LinkId=258412
I have read that this issue might be because of some hardware incompatibility. However, I think my machine is compatible with the emulator. Here is some information.
DirectX Version: DirectX 11
8GB RAM
Driver Model: WDM 1.1
Additional Information:
I have read that installing the 'January Update' might fix this issue. I tried downloading the update from this link: http://www.microsoft.com/enus/download/details.aspx?id=23854
However, the installer said that the update is not compatible with the product/version of the product I am using.
Usually the Repair function of the WP7.1 SDK is enough to fix all the issues. It runs the generation of the saved state of the emulator again.
Please try to delete files in %ProgramData%\Microsoft\XDE folder first (make sure you backup them somewhere else.), then run the emulator. If the emulator runs with a message "Windows Phone Emulator is doing a complete OS boot," let it boot. It takes some time though. This way you will know that the emulator actually can run on your computer. This won't generate a new saved state image, but the emulator should at least load.
Next, try installing WP7.1.1 SDK update from http://www.microsoft.com/en-us/download/details.aspx?id=29233. This update also installs additional 256MB emulator image besides the original 512MB image. It also generates emulator's saved states in the process, potentially fixing the issue.
If everything fails, then try these instructions to fix the saved state of the emulator:
Uninstall WP7.1 SDK
Manually delete these folders:
%ProgramData%\Microsoft\XDE
%LocalAppData%\Microsoft\XDE
Install WP7.1 SDK again.
Install WP7.1.1 SDK update: http://www.microsoft.com/en-us/download/details.aspx?id=29233.
Edit:
Btw, have you tried to reboot your computer? Once this fixed the issue for me.
Alright, I managed to solve this problem.
I reinstalled Windows and downloaded the SDK 7.1 again. The emulator works fine now!
#Paulos, thanks for helping!
I had the same problem for a long time. Try this:
Start up Visual Studio 2010, but before you start debugging, click on the tabs of all the open pages so that all the xaml pages and code behind pages can load.
I noticed it when I opened Visual Studio, but the first open page was a code behind page and not an xaml page, so when I first clicked on the tab of a xaml page, of course, it took some time to load the xaml page into the editor. However, when that and one or more open xaml pages were also loaded, the emulator started without the error message.
[2011-11-15 22:29:18 - MyAndroid] Failed to install MyAndroid.apk on device 'emulator-5554': device not found
[2011-11-15 22:29:18 - MyAndroid] com.android.ddmlib.InstallException: device not found
What troubleshooting steps have you done?
Has the app been installed on the emulator previously? If so, fully uninstall the app from the emulator first.
Try closing the emulator, and eclipse (if using eclipse). Then restart and try again.
If the issue keeps happening, you may need to delete the 'cache.img' in your AVD directory.
And if that doesn't help, delete the AVD, and recreate it.
