ionic Package io.ionic.starter signatures error

Question

My ionic project working nicely in command: ionic lab but when I execute "ionic cordova run" in terminal for build this app in android I am having the following error. Error: Failed to install apk to device: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package io.ionic.starter signatures do not match the previously installed version; ignoring!

Answer 1

Delete all the previous ionic apps from your android phone. Then run the command

ionic run android 

or

ionic run android --device

Hope it will solve your issue

Answer 2

When you previously installed any app with default package name given by ionic and trying to install another app with the same default package name, it will throw this error.

In config.xml file, change package name(id attribute of widget tag) from io.ionic.starter to any other package name of your choice(ex: com.example.hello)

This way you can keep all your ionic apps installed.

Answer 3

On android device, go to Settings > Apps and find your app in listing and open App info.

Click on the More Icon and select Uninstall for all users.

Then run commond ionic cordova run android.
