Incorporate the speech recognition feature of Google translate into own Android app

If you go to the Google translate app and click on the microphone icon you can speak into the microphone and translate will translate the text into the chosen language and output the result as text string. What I would like you to write for me is an Android Studio project (Android 4.0 and up) with a main_activity which consists of a textView and a button. When the button is pressed one can speak into the microphone. When done translate will attempt to translate the spoken text from Chinese into German and will output the resulting text into the textView. If the spoken text was not recognized a “could not be recognized” should be shown. That’s it. The reason for this is that Chinese is very focused on the pronunciation. Depending on the pronunciation a word could mean many different things. I want to use this to check my pronunciation in my own app which I wrote to accompany my Chinese class. Right now I'm switching between my app and Google translate. But I want to have it all in one place. Now I want the solution to be as simple and clean as possible. All the code needs to be well documented. I know there is more than one way to solve a problem. So don’t build a rocket ship. Keep it simple. You should be ready to also give me some advice on how to incorporate your code into my app if necessary. Please reference in your bid any previous projects you might have done with the Google translate API. If you are bidding on this project please start your bid with: “I can translate”. This is to make sure you read my description. If these three words are not the first three words in your bid I won’t even look at it. Thanks in advance.
