Because I need to contact Android in my recent work, I found that the signature conflict could not be installed correctly when updating the beta version of APP, and I realized that I still need to sign.

There are two ways to sign:

The first is to use eclipse.

The second one is generated by the trial command that comes with Android and needs dos.

The command is as follows: keytool-genkey-alias Android. keystore-keyalg RSA-validity 20000-keystore Android。 Keystore.

Right-click Project >>& gtAndroid Tools & gt> Export signed application package ...>& gt& gt Next & gt>> Select Create a new keystore? Select the saved address here and enter the password twice >>& gt& gt Fill in the basic information, as shown in the figure below.

The following figure shows the content generated by using the keytool -list -v -keystore command after generating android.keystore
