Android 8或更高版本：检查Google Play服务

Question

此方法继续返回0.根据开发人员文档，如果设备获得最新版本的google play，此方法应返回类似SUCCES的内容。 有谁知道如何使用它？

@Override
    public void onResume() {
        super.onResume();

        GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
        System.out.println("henkie: " + GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()));
    }

Answer 1

它正在返回SUCCESS 。 文档清楚地说明该方法具有int返回类型，并返回a

状态代码，指示是否有错误。 可以是ConnectionResult中的以下之一：SUCCESS，SERVICE_MISSING，SERVICE_VERSION_UPDATE_REQUIRED，SERVICE_DISABLED，SERVICE_INVALID。

要检查返回的内容，请使用以下内容：

int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if(status == ConnectionResult.SUCCESS) {
    //Success! Do what you want
}

Answer 2

请阅读文档： 0是SUCCESS

public static final int SUCCESS
The connection was successful.
Constant Value: 0 (0x00000000)

文档

Answer 3

只是

int statusCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if (statusCode == ConnectionResult.SUCCESS) {
    //OK
}

Answer 4

int state = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

        if (state == ConnectionResult.SUCCESS) {
            Toast.makeText(this, "SUCCESS", Toast.LENGTH_LONG).show();
            //goAhead();
        } else {
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(state, this, -1);
            dialog.show();
        }
