disable project/build automatically when you are exporting

i think is a problem of eclipse unable to detect the android command is still working or something similar.

of course there is ever the option of apk generation using ant outside eclipse you can generate an ant build.xml from your eclipse project more info in official android docs


this seem to be problem with your jvm. can you update your java and check again. also check this link


project/ clean worked for me. i think it could be related to the building of the project, as other users have posted.


the problem has gone until i have update adt and eclipse. i don't know which one solve the issue. now it's working smoothly for severeal signed export, with:

  • adt version: 22.2.1.v201309180102-833290
  • eclipse juno service release 2 build id: 20130225-0426
  • gentoo linux running java 1.7.0_45-b18.

update: few exports after, i still get crashes from time to time, but no very frequently.


may be you should try to add execute authority . you can try something like this

first close auto-build

cd /home/your name/android-dev/sdk/tools/

sudo chmod +x zipalign

done and good luck to you


i used the disable build automatically for months now, until i realized that aws plugins were slowing down the entire launch process. i uninstalled all aws plugins from help->installationdetails and everything now works perfectly as before. i do not need to disable build automatically any more.


disable project/build automatically before export the apk.

disable project->build automatically. i've noted that this works for me.
