java - Android 8 或更高版本：检查 Google Play 服务

Question

此方法一直返回 0。根据开发人员文档，如果设备获得了最新版本的 google play，则此方法应返回类似 SUCCES 的内容。有人知道如何使用这个吗？

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

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

Answer 1

它正在回归SUCCESS。文档清楚地指出该方法有一个 int 返回类型，并返回一个

指示是否有错误的状态码。ConnectionResult 中可以是以下之一：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

简单地

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();
        }
