I was facing this problem time and again.Got around a lot of forums, but couldn't find a logical solution for the issue.

I used to get this error message, . . . Uploading test.apk onto device 'emulator-5554' Failed to install test.apk on device 'emulator-5554': timeout Launch canceled!

this error is thrown as the start of emulator and deployment of application takes some significant time and before that the emulator times out.

A simple fix for this problem is keeping the emulator open when this problem occurs, *just run the application again. This only deploys the application on to the already started emulator *. There is not much time consumed during this run as the major part of the time during app deployment is because of slow start up of emulator.

Hope this helps!

I had the same problem and solved it by adding the paths of Android SDK folder tools and platform-tools to system PATH variable then restarting the device

I was getting the same errors with my devices  First be sure that you do not upload debug apk to a device having already installed the same apk but signed with release cert  In this case you ve got to uninstall it first from the device  In other cases my solution is to reboot everything      reboot device pskill emulator-arm exe pskill eclipse exe pskill adb exe   After that the device  adb and eclipse are working

Try changing the ADB connection timeout  I think it defaults that to 5000ms and I changed mine to 10000ms to get rid of that problem  If you are in Eclipse  you can do this by going through Window -  Preferences and then it is in DDMS under Android   As described here  Android error  Failed to install   apk on device    timeout

I was getting the same error    I Just left the AVD running even after it says  Failed to install   apk on device-emulator-5554   It automatically loaded the project afterwards   I think the error comes due the slow start up of the AVD

Restarting the device works for me     Using adb install can get the apk installed  but it s annoying to use it everytime you launch the app when debugging within eclipse

Just try the following steps    Go to Home screen before you start to run the application  No need to uninstall every time  Just uninstall your application once properly   Go to Setting -  Manage Application -  click menu -  filter -  Third party application  Check whether your application is there or not  After modifying your application just save it  Right click your project and select  Run as Android application   Note  once again  before running your application check whether or not your emulator is  showing the home screen      going to home screen  from eclipse go to menus  window- android virtual device- start

If you are running it on an Android Emulator you do not want to close it between runs  The system will try to load the app and it will time out because of how long it takes the emulator to boot up  You can fix this by increasing the ADB time by going to Window -  Preferences -  Android -  DDMS and increasing the ADB time out  default is 5000ms  or by leaving the emulator open and just running it after the emulator is up and running   I personally would recommend leaving the emulator open as it does load the apps relatively quickly once it is running  but it could be a drain on the system  Do whichever would help you more

When it shows the red writing - the error   don t close the emulator - leave it as is and run the application again

If unplugging the device and plugging it back in doesn t work  try increasing the upload timeout to something really huge like 20000 ms  It s at Window   Preferences   Android   DDMS    ADB connection time out  ms

Bolton  s answer worked for me  Some details     I got my phone a few weeks ago  I tried the HelloAndroid sample app right away  after installing req d software  etc    The app worked in the emulator AND on the phone--right away   Shortly after that  I rooted my phone but did not flash any roms or kernels  I was only experimenting on the emulator until yesterday  writing a simple notepad app   When I tried debugging the app on the phone  here s what I observed    Eclipse console reported the     failed to install on device    null   message  BUT The HelloAndroid app DID get pushed to the phone   It appeared in the apps drawer AND I was able to launch it   It simply would not launch on the phone from the Eclipse run    I searched around here and elsewhere last night  including this thread  with no luck  Finally  I rebooted my phone--which I never tried  doh    cause I didn t think it would make a difference--and the app launched from an Eclipse start   Still don t know the cause  but I ll come back here if I figure it out

I ran into the same problem and tried increasing the ADB connection timeout    Didn t work   I tried putting the  android-sdk tools  and  android-sdk platform-tools  in the PATH variable     No effect   I tried restarting Eclipse and letting the AVD startup before running  Same problem   I can sometimes get it to work with a combination of closing and reopening the project  followed by cleaning and rebuilding the project  It doesn t always work  but since I didn t restart the AVD this last time  I think the problem lies within Eclipse itself  You might try deleting everything in the  bin  directory of your project and then cleaning and rebuilding  It might be some temporary or intermediate files not getting deleted properly  Another thing I had to do was delete my AVD  It didn t delete properly  and I had to go in and manually delete the AVD s subfolder and then re-create the AVD  Some combination of these clears the problem up temporarily  Hope that helps

I had imported an existing project and started running    i too was facing the same problem  WARNING  Application does not specify an API Device API version is 11  Android 3 0     After all my attempts to resolve that failed I just created new project under other package to maintain the same names and copied all the file contents of the previously imporetd projects manually and again started running   to my surprise it  successfully executed in my first attempt   i think the problem was due to the lack of compatibilty of versions when imported   i hope it may help few

I get this from time to time  but it s usually related to the emulator being slow to start  Try again without closing the emulator between the retries  And if it still fails  please post the client logs  logcat    Another reason can be a ghost Eclipse process running in background and still bound to the debugging port  Close eclipse  look at process list and see if there s still an Eclipse running  Kill all of them and restart Eclipse again

Something else you might want to consider is a hard reset of your emulator by wiping your user data   In order to do this you  - right click your project name in package explorer - go to  run as  then  run configuration   - in the  run configuration  window click the  target  tab - then tick the name of your chosen emulator - tick  wipe user data   click apply  And the next time you start up your emulator it should prompt you asking whether you really want to wipe your data  Click yes  and hopefully it helps you to install the app

As for me  I had the same problem and it helped to increase SD volume and max VM app heap size   Android SDK and AVD manager - Virtual device - Edit  What is interesting  the back change of SD and heap to the previous values is OK  too  That means  that any change of emulator parameters and its rebuilding is enough   Simple restart won t help

restart the ADT or Try changing the ADB connection timeout  I think it defaults that to 5000ms and I changed mine to 10000ms to get rid of that problem  If you are in Eclipse  you can do this by going through Window -  Preferences and then it is in DDMS under Android

What Jichao said always works for me     Generally when I see this error if I am using Eclipse I will close and reopen the program   I will then uninstall the Application from the target phone   This sometimes fixes the issue but not always   Next I will open up the command terminal and head into the android-sdk then run     adb install  lt AppName gt  apk   This does the same thing that running through Eclipse does but it will give you an error message      9 times out of 10 it simply says  INSTALL ALREADY EXISTS  and I go and uninstall the application off the target phone again then run adb and I am working fine

OK  this approach will only be useful when you are connecting to a real device rather than to an Android emulator   Resetting the DDMS ADB connection timeout won t work nicely with a real device when there is a problem with USB debugging mode of the device    So  disabling and re-enabling USB debugging mode seems to resolve the issue by creating a new fresh ADB session on the device
