java - Android 8 或更高版本 : Check for Google Play Services

Question

此方法一直返回 0。根据开发者文档，如果设备安装了最新版本的 google play，此方法应该返回类似 SUCCES 的内容。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

它正在返回 SUCCESS。 documentation清楚地指出该方法有一个 int 返回类型，并返回一个

status code indicating whether there was an error. Can be one of following in ConnectionResult: SUCCESS, SERVICE_MISSING, SERVICE_VERSION_UPDATE_REQUIRED, SERVICE_DISABLED, SERVICE_INVALID.

要检查返回的内容，请使用类似的东西:

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