安卓8或更高版本：检查Google Play服务

Question

这个方法一直返回0。根据开发者文档，如果设备已经获得了最新版本的 Google Play，则此方法应该返回类似于“SUCCESS”的结果。有人知道如何使用它吗？

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

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

Answer 1

它返回SUCCESS。根据文档来看，该方法的返回类型为 int，返回一个状态码表示是否存在错误。可在 ConnectionResult 中选择以下之一：SUCCESS, SERVICE_MISSING, SERVICE_VERSION_UPDATE_REQUIRED, SERVICE_DISABLED, SERVICE_INVALID。

要检查返回的内容，请使用类似以下的语句：

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

int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()); if(status == ConnectionResult.SUCCESS) { //成功！做你想做的事情 } - Varun Goyal

"isGooglePlayServicesAvailable"已被弃用。 - Saravanabalagi Ramachandran

Answer 2

请阅读文档：0代表SUCCESS。

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

Answer 3

只需要简单地说，

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

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();
        }
