我正在编写此代码,它显示错误非静态方法GoogleApiAvailability.isGooglePlayServicesAvailable(上下文上下文)和GoogleApiAvailability.getErrorDialog(Activity activity,int errorCode,int requestCode)无法从静态上下文引用.

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();
        }
    }

}
