this is 32bit java
Note that you should use platforms/android-27/android.jar

Sigh,

This is where I really get lost. All I want to do is add ads to one of my aps which led me to Admob but that doesn't work the way it used to so you need to use FireBase which needs more MaxRamForDex (or was it that you also need Google Play Services and THAT requires more MaxRamForDex? Can't remember) and somewhere in there it says run SdKmanager.bat which I found in F:\Android\Android\android-sdk\tools\bin but when I click on it it just flashes a DOS Window and doesn't open anything. I found B4ASdkManager.jar set the path to sdkmanager.bat but B4A Sdk Manager has nothing in it Other than the Words 'Installed' and 'All'. I ran sdkmanager.bat from the command line it says

B4X:
ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files (x86)\Java\jdk
1.7.0_07\bin

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

but that IS a valid directory although I also have
B4X:
C:\Program Files (x86)\Java\jdk1.8.0_131\bin
C:\Program Files (x86)\Java\jre1.8.0_45\bin
C:\Program Files (x86)\Java\jre1.8.0_161\bin
not to mention when I look at my environment variables in System Properties JAVA_HOME is not mentioned.

I have an Android.jar in folders F:\Android\Android\android-sdk\platforms\android-10 through android-23. Where do I get 27? I have followed the instruction HERE: https://www.b4x.com/b4a.html to no avail.

I would pay someone to remote in to my computer and fix all of the configuration stuff for me. It has me baffled. I just want to write code. :p

Contact me if you want.

Can you post a screenshot of B4A Sdk Manager?

Here is sdkmanager.bat

So, I was able (I think) to fix the first batch file error. Evidently JAVA_HOME is supposed to be pointed NOT to \bin, but one directory up from that.
After fixing that there was no change in the B4A sdk manager output so I ran the sdkmanager.bat from the command line again and I get the following error:
B4X:
F:\Android\Android\android-sdk\tools\bin>sdkmanager.bat
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/s

I appreciate you guys taking the time to help with this. Keeping track of what belongs with what just fries my brain.
