除非您更新 Google Play 服务，否则 Google Map API Demo 将无法运行

Question

我在 android studio 中运行模拟器时遇到问题。模拟器提示我“除非您更新 Google Play 服务，否则 Google Map API Demo 将无法运行”。

我看到这个错误信息：

有人可以帮我吗？谢谢！

Answer 1

更新您的模拟器并创建一个 API 级别为 (with Google APIs) 或使用真实设备的模拟器。

Answer 2

虽然接受的答案适用于模拟器，但这在真实设备上可能是一个真正的问题，并且此解决方案不适用于真实设备。这可能发生在具有过时版本的 Google Play 服务的旧设备上。

为了克服这个问题，Google Play 服务库提供了一组 API 来检查 Google Play 服务的可用性，主要是 GoogleApiAvailability 类提供了一些方法来处理可用性问题，例如过时的版本。

现在，为了检测设备是否有可用的 Google Play 服务，我通常做的是创建一个辅助方法来运行检查

private boolean checkPlayServices(){
    GoogleApiAvailability gaa = GoogleApiAvailability.getInstance();
    int result = gaa.isGooglePlayServicesAvailable(getApplicationContext());

    if(result != ConnectionResult.SUCCESS){
        if(gaa.isUserResolvableError(result)){
            gaa.getErrorDialog(this,result, REQUEST_PLAY_SERVICES_RESOLUTION).show();
        }

        return false;
    }

    return true;
}

此帮助方法通过检查从isGooglePlayServicesAvailable 返回的错误代码来检查 Google Play 服务是否可用。然后它调用isUserResolvableError 来确定用户是否可以解决错误（例如，通过更新 Google Play 服务）。如果它是可解决的，则会显示一个对话框供用户确认他希望系统解决该错误。然后在 Activity 的 onCreate 方法上调用它，我运行检查如下

//I normally assume Google Play services is available
private boolean playServicesAvailable = true;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map_selector);

    //check for rare case where Google Play Services is not available
    playServicesAvailable = checkPlayServices();

    if(!playServicesAvailable){
        //hide UI elements and turn off features that rely on Google Play Services
    }
}

希望对大家有所帮助
