Why is the application not installed on Android?

Question

Android

Hello. I am developing an Android application for a customer using Apache Cordova. I don't have Android on my smartphone so I can't check. I sent the created apk file to the customer, but he cannot install it. After launching the application, the message "The application is not installed." I asked a friend to install - it was installed. Please tell me what could be wrong? How to get at least execution logs?

Answer 1

What execution logs, installer? Not the fact that there will be something meaningful.
A couple of reasons why the APK may not be installed:
- the device does not meet the requirements specified in the manifest
- there is not enough space on the device (you need more than apk weighs, if anything)
An easy way is to get yourself an emulator. It is in the SDK.

Answer 2

Hello!
1) Let the customer check and enable the installation of applications from "Untrusted sources". You can do this in the settings.
2) When building a project in Android Studio (if you are creating a release), then select both versions of the subscription (v1 & v2). I tried, for example, to sign only v2 and I had the same problem.
3) The problem is in the customer's phone - android version (requirements in the manifest file), memory size, etc. Also, just in case, check if the manifest has the necessary rights for the application to work correctly (for example, connecting to the Internet, etc.)
