Answer 1

Give this a try:

public class MainActivity extends Activity{

public Button call_btn, cancel_btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    call_btn = (Button) findViewById(R.id.call_button);
    cancle_btn = (Button) findViewById(R.id.cancel_button);
    call_btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            if(deviceIsTablet){
                if(isAppInstalled("com.skype.android")){

                }else{

                }
            }else{
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:123456789"));
                startActivity(callIntent);
            }

        }
    });

}

// determine whether or no the android device is a tablet or not
public static boolean deviceIsTablet(Context c) {
    return (c.getResources().getConfiguration().screenLayout
            & Configuration.SCREENLAYOUT_SIZE_MASK)
            >= Configuration.SCREENLAYOUT_SIZE_LARGE;
}

private boolean isAppInstalled(String app) {
    PackageManager packagemanager = getPackageManager();
    boolean isOnDevice = false;
    try {
       packagemanager.getPackageInfo(app, PackageManager.GET_ACTIVITIES);
       isOnDevice = true;
    } catch (PackageManager.NameNotFoundException exception) {
       isOnDevice = false;
    }
    return isOnDevice;
}

}
