I miss CA do much, I'm going to buy another phone. Question. What is the last Samsung phone that will run CA ? Thanks.

It's hit and miss but you need a phone that's going to stick on Android 9 (Pie) and not update. My guess would be a Galaxy S7.

I've been looking at a decompiled CA in a few APK tools and it looks like the issue is AndroidX and the new API's.

There are 2 lines that need adding into the .gradle then Android Studio may be able to convert the code.

I can't get in too deep because not all the support files are available but the error seems to be the way AndroidX handles the 'filename.9.png' initial splash screen.

Android uses the '*.9.png' as an instruction to resize the splash screen to the phones screen size.

This is where it seems to be falling over.

Could be.

I'm also suspicious of how AndroidX handles map files, which could be the next thing it does. On my Android 9 tablet, after the splash it loads the map.

Sadly I'm no Android expert.

One thing I did find is using the Android Studio AVD which mimics an Android phone for testing, that also falls over, but I did set it to mimic a Pixel2 which is the default.

Starting from Android 9, if the app uses Google Maps, its manifest must include the following line

Interesting.

I've had a clearout so I'll reinstall the bits I need to get at the manifest.

In the main the AndroidManifest.xml is read only but APKLab via Visual Studio code does allow editing.

Line inserted.

Still works on tablet under Android9 but won't run under Android10

Sad

The more I dig into the error:

java.lang.ClassNotFoundException
BaseDexClassLoader.java
dalvik.system.BaseDexClassLoader
findclass

Could this be the error line (3340), as pointed at by the crash dump:

invoke-interface (v0, v1, v2), Landroid/content/SharedPreferences;- getString(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;

Some characters edited out due to posting issue

Double dutch to me

It's trying to invoke java lang and it's java lang that it can't find. Trying to find exactly where the link is to see what it's calling is baffling me.

I have a Samsung S20 + 5G running:

- Android 11
- One UI version 3.1

So it would seem the problem of cameralert has progressed to the latest version of android.

Hopefully this will trigger some email updates to everyone in the thread who couldn't run CamerAlert on Android 10 and newer:

You will be pleased to hear that the app has now been updated and can be downloaded here: https://play.google.com/store/apps/details?id=com.pocketgpsworld.cameralert
