Application not installed on Xiaomi Mi3 and RedMi Android phones.

[Barry Paul]

Recenlty, I have created Android aaa.apk in App Inventor 2.

I do not have any error issue when I installed this apk on

various Android such as Samsung S4, Nexus 7, Samsung Ace, etc.

Recently when I installed this apk file in this Xiaomi Mi3 and RedMi phone.

I encountered this issue "Application not installed".

I have selected "Unknown Sources" under Security and Privacy.

Could anyone advise on this issue.

This apk is personal usage.

Thanks

It's possible that you've got blocks on that device for features you need in your app... What version of Android is your Xiaomi?

Yes, I have blocks feature in the Mit App Inventor 2.

Xiaomi Mi3 - Android 4.3.

I have no issue when I installed on other Android devices.

Do I need to self sign apk in order to work on Xiaomi Mi3?

I do not know how to self sign apk.

Do you have any idea?

I was asking you if you have something on the phone/device that's BLOCKING the app?  Are you setting the phone/device to accept programs that didn't come from the Google Play store?

Under Security , I have select "Unknown Sources", but it failed to install.
