I build a app at one PC and then copy to another, then I run my device, tip:
Re-installation failed due to different application signatures.
actually, I did not sign app . unfortunately this apk I have send to my user and them update it automatically (app check version and then download and call to install), so them failed to install when update.
my questions:
I have done following this post: enter link description here
将一台电脑的调试密钥库复制到另一台电脑将解决此问题。
Yes.
Go to C:\\Users\\yourName\\
in your first computer and copy either the whole .android
directory (recommended), or copy the debug.keystore
file in the .android
directory, onto the second computer in the same place as the first computer.
That, or you can just uninstall your app on your phone, and then running it again from the second computer will work fine.
Note : Eclipse may not be targeting the correct path to your debug.keystore
file (you may have put it in the wrong place, or something else happened). In that case, you would have to change that in Eclipse preferences:
Window --> Preferences --> Android --> Build
Then, look at the default debug keystore . Perhaps, if it's not pointing in the right place, use the custom debug keystore to point it in the right place.
