How to set a custom keystore for debugging in eclipse for android

Question

I have a custom keystore that I use for signing my apk. now I want to use the same keystore for debugging. when I go to eclipse->windows->preferences->android->build and set my custom key store I get "Keystore was tampered with, or password was incorrect"?

Answer 1

I had the same issue and here are the steps to properly create a custom keystore that can be used for debugging in Eclipse:

Basically what you should do is that change both storepasswd and keypasswd for the alias androiddebugkey to "android".

Here are the commands:

keytool -changealias -keystore mykeystore.keystore -alias [old alias] -destalias androiddebugkey
keytool -keypasswd -keystore mykeystore.keystore -alias androiddebugkey
keytool -storepasswd -keystore mykeystore.keystore

If you don't know your old alias, look it up using

keytool -list -v -keystore mykeystore.keystore

in Command prompt not able to enter the password

Answer 2

Simplest way to set custom keystor.

No need of commands.

Steps (for ADT):

1.Export any project (It will show you an option to create custom keystore).

create your keystore with an extention " .keystore " and give password android and press next.

2.

give alias name = androiddebugkey and password = android

now press finish and your keystore is ready.

1.Go to windows -> preference

and give the path of your custom keystore file

I got the same problem when trying to debug the released apk.. so I tried the Saeid solution with no success. Then I found this blog ( http://blogprogramistyandroid.blogspot.com.br/2011/04/converting-release-keys-to-debug.html ) which I got the simplest solution for the problem:

Make this command:

keytool -importkeystore -v -srckeystore release.keystore -destkeystore custom-debug.keystore -srcstorepass release-pass -deststorepass android -srcalias release-key -destalias androiddebugkey -srckeypass release-pass -destkeypass android

Of course substitute passwords and alias of source keystore with the one used in creation of release keystore.

Done

Answer 4

We have the same problem some time ago at our office. Since we needed this quite often we wrote a simple script to make it easy to to convert release keystores to debug ones.

The script is available on https://github.com/IntellexApps/key2debug

We are using it for some time now, so should be quite stable.

cheers!
