I am trying to manually add text file into assets folder of .apk using aapt tool or can able to add any ZIP reader. After adding text file I resigned .apk by using jarsigner and aligned it using zipalign.

Here problem is, that the final .apk is not getting installed on my device.

I referred these posts but they didn't help

Can I resign an .apk with a different certificate than what it came with?

Repackage APK file to contain custom assets - what build tool to use?

SOLUTION: This helps to fix my issue

Device shows Application not installed error

if one application with special package name has been installed on your device, the next instance of that can be installed, only if both of them has the same signature. so if you want to do that, you must remove the previous one, or you must change package name.
