Android Question SDK version command checking

[Robert Valentino]

I'm over 70 and forget what commands are available for what SDK versions.

I just used a command

Dim paths() As Object = GetContext.RunMethod("getExternalFilesDirs", Array(Null))

on a device running OS 4.1.2 and SDK 16 now this command is not available until SDK 19

Now my min / max sdk in my manifest is set to

<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="29"/>

Is there a routine that will type check (not sure if that is the right term here) and let me know that commands are outside my min skd version (something I could put 'ignore on if I was checking the SDK around it)

I am sure with everyone being forced into moving up to SDK 30 that we all may run into these cases. I was lucky I was testing on a very old device so it caught this bug. But I am sure some can/will make it to production if we aren't careful

Any routine for this anyone know of? Is this something the IDE can check for us?

Not sure if I should put this in the Wish list, but if someone has a routine that we can run then please share.

It is added in Api 19.

I think you missed I said that (this command is not available until SDK 19) but the device I said was running API 16 (device running OS 4.1.2 and SDK 16)

Thing I forgot to do was

if API >= 19 then getexternalfilesdir command else .... do something end if

If I could get something to pre-check my code to make sure I am not using commands without the API check around them.
Or maybe something to show me what API the commands I am using are.

Phone library. Phone.SdkVersion

Let me make it more simple.

I want something to show / tell me what API is required for ALL the commands I am using

I don't think you will find it. You will need to look each one up in the Android development documentation to see when it was made available and if it is deprecated.

I guess a lint checker is what I will start looking for? Must be something that we can say check my code against SDK n and have it report all calls that aren't available for SDK n

(note: n being any sdk number)

I just used a command

Don't. Use RuntimePermissions.GetAllSafeDirsExternal.
