I never knew that "Android" and "iOS" were programming languages. Oh that's right, because they AREN'T.
On Android you have as predominant languages: Java, C#, JavaScript.
On iOS you have as predominant languages: Objective C, Swift, C#, JavaScript.
Can we please just stop conflating things here, it demonstrates an embarrassing lack of understanding of the tech landscape. What Stack Overflow is showing is the popularity of topics tagged with certain metadata. A React-Native query that targets iOS while programmed in JavaScript could have the tags "iOS", "JavaScript", "React Native", while an Android query of a similar type would lose the iOS tag and gain the Android one. However, note, the Programming LANGUAGE tag of "JavaScript" is still the same and will count towards those stats.
IF you want to talk about Android or iOS, then talk about the programming environment/platform that holds most interest for developers in various and strip out all the PROGRAMMING LANGUAGE tags (unless they are platform specific), if you are talking about programming languages, then strip out all the ENVIRONMENT tags.
