If you are using webpack with uglify for Android, you must add TNS_SwipeRefreshListener to the mangle exception list.

webpack.config.js

if (uglify) {
    config.plugins.push(new webpack.LoaderOptionsPlugin({ minimize: true }));

    // Work around an Android issue by setting compress = false
    const compress = platform !== "android";
    config.plugins.push(new UglifyJsPlugin({
        uglifyOptions: {
            mangle: { reserved: [ ...nsWebpack.uglifyMangleExcludes, "TNS_SwipeRefreshListener" ] },
            compress,
        }
    }));
}
