How does cordava generate Android apk files?
Apk is encapsulated in Eclipse, and the compiled android project will automatically generate an apk file in the bin directory of the project, which is different from J2ME and does not need manual packaging. As long as the code is changed, it will be built automatically, and the built apk is signed. You can also export a signed or unsigned apk under the Andoid tool menu in the right-click menu of project.
