Java – Non-static methods cannot be referenced from a static context isGoogle PlayServicesAvailable and getErrorDialog

I’m writing this code, which shows the error non-static methods GoogleApiAvailability.isGoogle PlayServicesAvailable(Context context) and GoogleApiAvailability.getErrorDialog(Activity activity, int errorCode, int requestCode) cannot be referenced from a static context。

package com.xamarin.gcmexample;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.GoogleApiAvailability;
import android.util.Log;
import android.widget.TextView;

public class Main extends AppCompatActivity {
    TextView msgText;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        msgText = (TextView) findViewById(R.id.msgText);

}
    protected void IsPlayServicesAvailable ()
    {
        int resultCode = GoogleApiAvailability.isGooglePlayServicesAvailable(this);
        if (resultCode == ConnectionResult.SUCCESS){
            msgText.setText("isGooglePlayServicesAvailable SUCCESS");

}else{
            GoogleApiAvailability.getErrorDialog(this, resultCode, 1).show();
        }
    }

}

Nurlan has pointed out the right answer.

Replace your method

protected void IsPlayServicesAvailable() {
    int resultCode = GoogleApiAvailability.isGooglePlayServicesAvailable(this);

if (resultCode == ConnectionResult.SUCCESS){
        msgText.setText("isGooglePlayServicesAvailable SUCCESS");
    } else {
        GoogleApiAvailability.getErrorDialog(this, resultCode, 1).show();
    }
}

Pass

protected void IsPlayServicesAvailable() {
    int resultCode = GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(this);

if (resultCode == ConnectionResult.SUCCESS){
        msgText.setText("isGooglePlayServicesAvailable SUCCESS");
    } else {
        GoogleApiAvailability.getInstance().getErrorDialog(this, resultCode, 1).show();
    }
}
