我想用签字这里找到手动方法的应用的http://developer.android.com/tools/publishing/app-signing.html#signing-manually

我们的previous外部开发者发送给我，我需要这个（不知道为什么他们会需要三？）三种密钥库文件。当通过尝试登录我的应用程序的过程中会提示我用的存储密码我不知道（我试图从他们那里得到这一点）。

是否有可能对我来说，这个改变自己？我有三个密钥库文件，但我不知道是否因为应用程序已经签署并发布到店，这将有作用，我想为更新应用程序，而不是发布一个全新的之一。

我知道这个问题已经被问之前，我只是不知道，如果直接涂抹我为我的应用程序这些问题的答案是的已在谷歌Play商店和发表

解决方案

我有几个建议给你。

如果你不知道所有的3密钥存储的密码，那么没有人会帮助你。您必须创建新包的名字（这是从谷歌玩最后一次现场应用不同的）新的应用程序，谷歌上添加新的应用程序播放

现在如果你有密码，然后先得到最后一次现场APK。生成符号键（SHA-1安培; MD5）从APK文件检查答案这里如何从APK生成密钥

然后得到SHA-1和后; MD5所有3密钥存储和匹配APK的SHA-1安培; MD5。他们匹配，那么您就可以知道哪些密钥存储用于标志APK（这是​​目前在谷歌播放）

使用该密钥存储产生新的APK：）

I am trying to sign an app using the manual method found here http://developer.android.com/tools/publishing/app-signing.html#signing-manually

Our previous external developers have sent me three keystore files that I need for this (not sure why they would require three??). When going through the process of trying to sign my app I am prompted with a keystore password which I do not know (I'm trying to get this from them).

Is it possible for me to change this myself? I have the three keystore files but I'm not sure if this would have an effect as the app has already been signed and released to the store and I want to update the app rather than release a whole new one.

I know this question has been asked before I just wasn't sure if those answers directly applied to me as my app is already in the Google Play store and published

解决方案

i have few suggestion for you.

if you don't know password of all 3 key-store then no one will help you. you must have to create new app with new package name(which is different from last live app on Google play), add new app on Google play

now in case you have password then first get last live APK. generate sign keys(sha-1 & MD5) from that APK file check answer here how to generate keys from APK.

then after get sha-1 & MD5 from all 3 key-store and match with APK's sha-1 & MD5. they are match then you are able to know which key-store are used for sign APK(which is currently on Google play)

use that key-store to generate new APK :)
