Android : Unable to install app

Question

I am unable to install my app on my Lenovo Phab PLUS (Lenovo PB-1 770M, Android 5.1.1 API 22) through either Android Studio or by copying the APK manually.

Through Android Studio: I get the error "Failure to install APK [INSTALL_FAILED_DEXOPT]". It suggests me that there might be an existing app on the phone with the same package with stale dexed jars and prompts me to uninstall the existing app. However, when I proceed with "yes", it simply fails and throws the error "Error installing APK". I have attached the screenshots here.

Manually installing APK: It tries to install the app but shows up a screen saying "APK not installed".

The problem is, my app is not listed in the Settings->apps directory on the phone. So I have no way to figure out if there is an existing app with the same package name on the phone. Since I cannot see it, I cannot uninstall it manually, hence I cannot install anything with the same package name again. Can anyone help with this?

I am using Android Studio 2.3.3

does your phone have multiple user accounts? if yes switch to another account and uninstall app from that account — Divyesh Patel, Oct 27 '17 at 05:41

In Android studio select Build-> Build APK(s). Try to install new build generated by this step.

This problem can arise based on a lot of reasons. One of my friend had the same issue and when I tried fixes with him, following are the steps we followed:

Clear cache of your project File -> Invalidate cache/restart
Restart your emulator or try to create new and delete the existing one. And then the problem was far gone.

I know this is not the exact fix for you, because your problem can't be anticipated so easily, but I just wanted to share with you, hope it solves your problem.

Just create a new Android Studio project with the same Package name.

Install the new Project with the same package name. Install now the original app.
