Displaying the SHA1 certificate fingerprint

There are two type of certificate fingerprint, debug and release.

To display debug certificate fingerprint in Linus, simple open Terminal and type the command:
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android


display debug certificate fingerprint


To display release certificate fingerprint, you need to create the release keystore and and sign the .APK once.

- Right click your project and select Android Tools -> Export Signed Application Package...


- Accept the selected project and click Next.


- Select Create new keystore, browse to select Location and enter Password, and click Next.


- Enter Alias, Password, Validity and at least one Certificate issue field, and click Next.


- Select destination APK, and click Finish.


After created the release keystore and and signed the .APK. you can display the release certificate fingerprint.

- open Terminal and type the command:
keytool -list -v -keystore <your_keystore_name> -alias <your_alias_name>

where:
<your_keystore_name> is the path and name of the keystore, including the .keystore extension.
<your_alias_name> is alias that you assigned to the certificate when you created it.



If you get error of "keytool error: java.lang.Exception: Keystore file does not exist", read HERE.

How am I supposed to write the key in the manifest before exporting the apk?!

It's also my question...

What I did was to update the manifest with release key and export again, this time choosing the existing key instead of creating new key. It seems to work.
