Answer 1

First you need to now that you can use the implicit intent, android documentation provide us with a very detailed common intents for implementing the map intent you need to create a new intent with two parameters

• Action
• Uri

For action we can use Intent.ACTION_VIEW and for Uri we should Build it ,below i attached a sample code to create,build,start the activity.

 String addressString = "1600 Amphitheatre Parkway, CA";

    /*
    Build the uri 
     */
    Uri.Builder builder = new Uri.Builder();
    builder.scheme("geo")
            .path("0,0")
            .query(addressString);
    Uri addressUri = builder.build();
    /*
    Intent to open the map
     */
    Intent intent = new Intent(Intent.ACTION_VIEW, addressUri);

    /*
    verify if the devise can launch the map intent
     */
    if (intent.resolveActivity(getPackageManager()) != null) {
       /*
       launch the intent
        */
        startActivity(intent);
    }
