MrKim · Feb 20, 2018

I am trying to increase MaxRamForDex from 512 to 1028 but compile throws the following error:

Strange. Have you tried to restart the computer?

Which version of Java is installed? Try to install 64 bit

How do I determine if I am running 64 bit?

it it installed in C:\Program files (x86)\Java
or in c:\Program Files\Java\?

Check the path in the IDE paths dialog as there could be many versions of Java installed.

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.

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

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

According to the screenshot above, 'About Java' I am running 8

DonManfred · Feb 28, 2018

Then it seems you need to use a newer version of Java 8

Check the results here https://www.b4x.com/android/forum/pages/results/?query=Unsupported+major.minor+version+52.0

It looks like a network issue. Maybe you need to configure the proxy settings in the IDE.
