Android Question Parse Error

[Robert Valentino]

When I use this library (mp3agic-0.9.1.jar) in B4J it works OK, but in B4A I get this error

B4A Version: 7.30

PARSE ERROR:

...while parsing com/mpatric/mp3agic/AbstractID3v2FrameData.class

How can I fix this or can I

Update java to version 8

 

[Robert Valentino]

Thought I was or rather I believe I am :

JAVA_VERSION="1.8.0_60"

JAVA_VERSION="1.8.0_60"

Did you select the correct java in Tools configure Paths?

 

[Robert Valentino]

I have the SAME exact path in both my B4J and B4A

B4J works fine B4A gives me the error

I believe the problem is somewhere else????

[DonManfred]

even java 8 can be updated. I have jdk1.8.0_141 (151 is uptodate)

I had a similar problem..solved wiht 151
then try Java\jdk1.8.0_151\bin\javac.exe

 

[Robert Valentino]

Moved to 151 and same error

Are you sure that it is an Android library?

 

[Robert Valentino]

No, I am not. It is probably an Windows library (the reason it works with B4J)

I tried to compile it using the SimpleCompiler and got

Starting step: Compiling Java code.
javac 1.8.0_151
E:\mp3agic-master\src\main\java\com\mpatric\mp3agic\FileWrapper.java:6: error: package java.nio.file does not exist
import java.nio.file.Files;


Between this and (as you will see in other posts) trying to create a MediaBrowserServiceCompat service I am so frustrated and lost that it hasn't been any fun for a few days.


PS Welcome back (know you have been busy with upcoming releases)
