Eu criei alternância animada e funciona perfeito seandroid:checked="true" ie: joga drawable de 1-9 mas seandroid:checked="false" está preso em drawable 10, mas deve jogar de 10-20. Ele funciona perfeito a partir de então, mas quando o aplicativo inicia, tem o problema acima.

Por que é preso em drawable 10 quando na realidade deve estar em 20 como esta é a imagem final (Off) atualmente como seu preso em 10 parece que ainda está ON.
