Eclipse packs the android project into a signed APK File

After the android project is developed, it is necessary to package the android project file into an APK file and finally download it to the real machine for running. The following is a personal APK package process, which is recorded in text format. For more information, see http://www.cppblog.com/fwxjj/archive/2010/05/24/426208.html.

In fact, the lazy way is to find the file directly in the bin directory of the eclipse project, which is an APK file automatically generated by the eclipse system.

1) generate a keystore

Run the following command in the c: \ Program Files \ Java \ jdk1.6.0 _ 10 \ bin> directory and enter keytool-genkey-alias android. keystore-keyalg RSA-validity 100000-keystore android. keystore

It indicates that-validity indicates the validity period of the certificate, which is set to 100000 days. The space and the Return key are counted as passwords.

After the command is executed, the android. keystore file is generated in the c: \ Program Files \ Java \ jdk1.6.0 _ 10 \ bin> directory. -1
