Getting deployment error for an android app
<p>I am building an android app in xamarin studio which is using third party libraries like Newtonsoft.Json etc. It was working well. Then there is a requirement of integrating google map into the app. As I was new to integrating google map in an android app, I googled for helps and used them. I am using the class GoogleMap in my code. I have installed Google Play Service(Maps) in the solution. Since then I am getting deployment error. When I am cleaning the project it is successful. When I am rebuilding the project it is also successful. It shows no error. However when I try to run the app from xamarin studio it tells me an deployment error occurred.</p>

<p>If I try to drag the successfully build apk to the running emulator I get Certificate error.</p>

<p>What to do in this situation.</p>

<p>Thank you. </p>

<p>The following is my build output. Please note that I am getting build failed when I try to run the app. However when I am just building or re-building the app or cleaning the app I get Build Successful</p>

<p><strong>Build Output</strong></p>
