I have the app ready so trying to sign it. I read the dev docs. Am using eclipse and adt so started using export. Am able to export a sample app. While exporting they says to have the key. I have created a new file and proceeded and finally I got the output apk. Once whn I opened the key file, I cant read anything. So I am confused.. Will it be readable?? or like the same? Please tell me about the certificate they are mentioning on signing the app, is this same as the one, the file I have created?? Thanks in advance..

Your keystore file (e.g. mykeystore.keystore) should not be readable in a text editor or other such program.
Please tell me about the certificate they are mentioning on signing the app, is this same as the one, the file I have created??
Once you have finished signing your APK using your keystore (see Signing your Application), the APK will contain a META-INF directory that contains a CERT.RSA file, which is the application's certificate. You don't need to worry about this file at all, and it is automatically generated by keytool when you sign your APK.
Your private key (see Obtain a Private Key) is also referred to as your signing certificate, and is what is stored in the keystore. This is the key that you use to sign your application. After you have generated this key using keytool, you shouldn't need to worry about it anymore.

So I have a client that has sent me a keystore file and told me that is how I will get the APK. I followed the directions for generating an APK from a keystore here:
https://developer.android.com/studio/publish/app-signing#sign_release
What am I missing here? Why am I still loading the default blank project I am trying to load? Have I overwritten something?
i think you miss understood the concept of a keystore .
the keystore is used along with a password to sign an apk or aab of an existing project.
so if a client sent you a keystore how do you expect to get an apk from the keystore file ? it doesn't contain an apk in it .
I have lost my keystore file now i need to update my app on play store is there any way to get my keystore file i have my old signed apk please any answer will be appreciated

and mark the options like below:
You cannot recover a lost keystore.
The signature on your existing APK is just a signature- you cannot reproduce the signature without the key that generated the signature.
Google does not store, keep track of, or ever have access to your keystore. It is completely on the developer to manage the keystore.
Your options are:
Find the keystore
Generate a new keystore and re-upload your application as a new application. You will be starting completely fresh with this option.
I have a .apk file. And I want to get the platform key (with .jks or .keystore format)from this .apk to sign another .apk. Is it possible? If yes, how to do it?
If you mean to sign APK by retrieving all data necessary for signing from another APK ... answer is NO.. you need to get that keystone to sign same or another APK.
I am creating an in-app purchase app. I have uploaded apk file once while creating the application in Google Play developer console. But now when I am trying to upload another version of apk file it is showing error of different SHA-1 keys. I have changed the version code and package name is also same. I referred questions here and I got to know that apk should be signed with same certificate.
But my problem is when I export the project from Eclipse to generate signed apk it is not allowing to use existing keystore; moreover when I select existing keystore the dropdown list of alias are empty. So each time I have to create new keystore. Also it is showing "Invalid keystore format" on selecting exiting keystore. Please provide me with some solution to how can I generate an APK with same SHA-1 key.
Is this apk file generated from another computer than the first?
Make sure to have the same .keyStore file on your different PC.
How to extract the apk file using the jarsigner to get the keystore to update my Android application?
This is not mathematically possible. The complete and entire point behind digital signatures is that they cannot be reverse-engineered except with more computing power than anyone will have.
You should already have the keystore for your app -- you used it once already to sign the APK file. If you lost that keystore file, restore it from a backup.
