Please provide more information so that I can understand the issue to help you out.

JEWEL · November 13, 2024, 6:42am

You're doing wrong in rules. You need to define the package/class name with the -dontwarn attribute.

-dontwarn com.google.gson.internal.bind.**

dependencies:
 # - annotation-1.1.0.jar
 - annotation-experimental-1.1.0.jar
 - annotations-13.0.jar
# - collection-1.0.0.jar
# - core-1.5.0.jar
# - core-common-2.0.0.jar

And you're trying to override AI2 provided libraries. If you still want to override provided classes so you need to enable the filter_mit_classes attribute from the fast.yml. Otherwise, you'll get apk build failed issue.

And you don't need to use aar when you're declaring jar. Or if you declare aar instead of jar, you need to run once fast sync before build.

Thanks a lot, issue is resolved

JEWEL · November 13, 2024, 7:14am

You're welcome

Patryk_F · November 13, 2024, 7:34am

After this suggestion I looked at the proguard configuration in more detail and there was indeed a mistake:

Patryk_F:

-keep class pl.patryk_f.extension.helpers.MyIcon { *; }
-keepclassmembers enum pl.patryk_f.extension.helpers.MyIcon {
    public static **[] values();
    public static ** fromUnderlyingValue(java.lang.Integer);
    public Integer toUnderlyingValue(); 
}

I'm not sure if this is necessary, but if so, the name of the entire Integer class is missing here.
public Integer toUnderlyingValue();

It should be:
public java.lang.Integer toUnderlyingValue();

JEWEL · November 13, 2024, 8:40am

These rules will be sufficient to keep all required things from the helper class.

-keep enum pl.patryk_f.extension.helpers.MyIcon {
 public protected *;
 public static **[] values();
 public static ** valueOf(java.lang.String);
}

FAST will handle it by default from the next update v1.2.8.

JEWEL · November 13, 2024, 9:45am

An update is available v1.2.8

Date built: 13.11.24.15.09

Modified the default ProGuard rules to keep all required methods and values from helper classes.

Patryk_F · November 13, 2024, 1:09pm

Wasn't this introduced in an earlier version?

JEWEL · November 13, 2024, 1:25pm

FAST was keeping helper classes, but there was an issue. I've fixed it in v.1.2.8. You could also do the same from earlier version of FAST by using custom rules with the proguard-rules.pro.

JEWEL · November 13, 2024, 2:53pm

Please make sure the @DesignerComponent annotation is present in your component source code.

See here.

Passos_0213 · November 13, 2024, 4:00pm

Excellent and very fast! Thank you @JEWEL .

JEWEL · November 13, 2024, 4:10pm

You're welcome @Passos_0213

Patryk_F · November 18, 2024, 11:58pm

The ListView component has changed, its new methods are not available in Fast.

JEWEL · November 19, 2024, 1:43am

If you are referring to these changes, you only need to add the dynamicanimation-1.0.0.jar into Fast/libs/appinventor/ and I will include it with the next update.

Patryk_F · November 19, 2024, 2:16am

I mean the AndroidRuntime library.

JEWEL · November 19, 2024, 2:48am

Thanks, I've also noticed that after wrote my last reply. I think I've to build the AI2 source to get the latest AndroidRuntime.jar.

JEWEL · November 19, 2024, 8:16am

~~FAST will require a minimum of JDK11 after these changes are implemented.~~

TechHamara · November 21, 2024, 9:10am

Hi @JEWEL
I am use -o build flag and then extension size increase.
How can work this flag?
