Android Question App has Stopped on Android

[algPoS]

Hi All,
Android is still new to me so please forgive me if this has been asked before

I have just updated to B4A 13.40 and when I complile and send my App to my Motorola Hand held device my App shows "unfortunately, algPoS Mobile has stopped"

The App installs with no Errors as it asks me to OK the install of the App

I have been using android:targetSdkVersion="16" and before the update my app would work perfectly

Could someoe please advise as how I can get my App to work again

Below is the Manifiest from my project if I need to change anything Please tell me and I will do this.

Kind Regards
Andy

targetsdk = 16 is for android 4.1 devices.

In 2026 you have to use targetsdk 35

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

When an crashes there is always something in the logs, in some cases in the unfiltered logs. It will reveal more information.

In this moment the required TargetSDK is 35 as required from Google.
If you have updated B4A from an older version be sure to redownload all the needed files from the guide a make a completely new fresh installation.

So I can get my app working again on Android 4.2 by just downgrading to targetsdk=16?!?! That’d be Great!!

Probably it would be better to lower the MinSDK to....... I think 14, not sure.
Then it depends if your project does not use some library or function not available for Android 4.2

Hi All well I managed to get the app to work on my Android 4.2 terminal (hand held Barcode terminal like they have in the supermarkets) I just chaged the android.jar path to C:\B4A\platforms\android-28\android.jar and it worked again so I shall keep it at that

Thank you for all who have helped.
