My Gradle

            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

... implementation 'com.github.tarek360.RichPath:animator:0.1.1'

When I run the application on API 28 everything works fine When I run the application on API 16 (Android 4.1) or 19 (Android 4.4), the application crashes

oh too old Android version :D please provide you vector drawable file.

I found a solution.

In your app's build.gradle you need to include

android {
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }
}

And for vector support for less then API 21, add the following to onCreate AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);

It works, but the animation doesn't work as it should. I need the lines to be drawn one by one (I show how to draw the Japanese alphabet). Now the first line is being drawn and the rest lines just appear (no drawing)

Here is the animation code (for API 28 works as expected)

private void svgDrawLines() {
        long delay = 500;
        long speed = 1000;
        String kanaPrefix = alphabetType == AlphabetModel.AlphabetType.hiragana ? "h" : "k";


        svgView.setVectorDrawable(getResources().getIdentifier(kanaPrefix + "_" + AbcModel.latinRows.get(rowNumber).get(selectedItem), "drawable",
                MyApplication.context.getPackageName()));

        RichPath[] svgPath = svgView.findAllRichPaths();

        for (RichPath path: svgPath) {
            path.setStrokeColor(getResources().getColor(android.R.color.transparent));
            // TODO: только первый раз работает изменение толщины линий, а последующие нет
            // path.setWidth(5);

            RichPathAnimator.animate(path)
                    .trimPathEnd(0,1)
                    .startDelay(delay)
                    .duration(speed)
                    .strokeColor(getResources().getColor(R.color.colorSilver))
                    .start();

            delay = delay + speed;
        }
    }

Vector drawable file

So How to fix animation? Or another solution for correctly work?

Thanks!
