# How to Reading and parsing text file android?

Recently, I've come accross an [interesting challenge](https://answers.mindstick.com/qa/94403/what-was-the-most-interesting-challenge-you-faced-while-developing-an-android-application), which I apparently cannot solve. I'am an [android](https://www.mindstick.com/articles/13046/10-reasons-why-i-prefer-android-vs-iphone-ios) [beginner](https://www.mindstick.com/forum/23159/need-beginner-project-ideas), and what interests me is: How does one read from a [text file](https://www.mindstick.com/forum/12828/converting-a-text-file-to-an-array-in-java)(on phone, as a user) and [store](https://www.mindstick.com/articles/13125/tips-to-increase-sales-of-your-woocommerce-store) that parsed file into a [string](https://www.mindstick.com/articles/1527/string-split-in-c-sharp), processes the string, the outputs it?

## for example:

code to read a file . . code to count [characters](https://answers.mindstick.com/qa/42112/who-is-the-originator-of-avengers-characters) . . . code to print the [result](https://www.mindstick.com/blog/12011/advantages-of-getting-result-oriented-seo-from-an-agency) on the [phone screen](https://answers.mindstick.com/qa/109586/how-to-restoration-android-phone-screen-rotation-troubles).
