The first one: use keytool.

keytool-list-v keystore file-store pass 123456

Among them, keytool is jdk's own tool; Keystorefile is a certificate file signed by Android.

The second type: direct viewing in adt 22.

If you use adt 22, you can use it directly in Eclipse: winows->; Preference-> Android-& gt； Construction. As shown in the following figure:

The value of "SHA 1 fingerprint" is the sha 1 value of the Android signature certificate.

Second, the actual situation

I think Baidu is quite humanized, so I cut a picture. Gee, suddenly admiration surged in, and something really happened. The actual screenshot of the second method is like this, and then there is a black line.

Is the second method doesn't work at all! ! ! ! My God, Lady Gaga.

Use keyboard tools

First, configure environment variables.

Because keytool tool is needed, and keytool is a tool in jdk, so first add the directory where jdk/bin is located to the path of environment variable.

Look where my keys are.

Add the PATH e: \ program files \ Android others \ JDK \ bin to the path variable:

Second, find another file, debug.keystore

This file is located in the directory where you put the project. If it is the default, it is in c: \ documents and settings \ administrator \. Android directory.

Third, run the command.

1. use the cd command to switch the working directory to c: \ documents and settings \ administrator \. Android directory.

2. Input: keytool-list-keystordebug.keystore.

3. Enter the password of the keystore: if it is not set, it is blank here, so you can enter it directly.
