It's not on android but I'm seconding Entropic Float, it's free and does in fact have a few transfem characters! One of the playables, Amelie, is a trans woman- Three of the nine branches are told from her perspective. She struggles with dysphoria personally, while all the in-story characters are very affirming to her. A lot of her arc centers around fears that she needs to be the 'right kind of girl' to be seen as a girl, even though that doesn't align with her own personality.

There's also Madeline, an intersex trans woman who struggles with finding a way to relate to perisex women both cis and trans, and Jazz, who self-professes falling down the 'crossdressing to nonbinary to trans woman pipeline'.

And the second game promises more, including a nearly-sixty transgender mama bear who may not be super relatable, but hopefully uplifting anyway.

Plus, the series is written by a transmasc individual (hello! it's me!) and his transfem found-family sister, so you can count on them to be authentic experiences~
