How to install the new apk file without uninstall the old apk file on an Android device?
<p>My apk file size is 2MB. First time installing the apk file in the device there is no problem.
Suppose some changes in the application after that generated the new apk file. I am try to install the new apk file in the same device then it shows some message first uninstall the previous one(i.e. , same application) in the device. But small apk files, I am not facing this problem.</p>

<p>Is it possible to install the new apk file without uninstall the old one?</p>
