Google云消息传递:如何通过GoogleApiAvailability Class请求Google Play服务可用性

我想与我的Android应用程序使用谷歌云消息传递。据说你需要先检查谷歌播放服务的可用性。但我不知道如何实现这一点。刚刚通过GoogleApiAvailability Class搜索过。问题是我不明白如何设置检查和使用方法.getErrorDialog()在我的情况下。据说requestCode是“调用startActivityForResult时给出的requestCode”。但是如何使用呢?

public void onResume() {
    GoogleApiAvailability availability = GoogleApiAvailability.getInstance();

    int checkForGPS = availability.isGooglePlayServicesAvailable(this);
    if(checkForGPS != ConnectionResult.SUCCESS) {
        availability.getErrorDialog(this, checkForGPS, requestCode);
    }
    super.onResume();
}

试试这个,

private boolean checkPlayServices() {
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if (resultCode != ConnectionResult.SUCCESS) {
        if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
            GooglePlayServicesUtil.getErrorDialog(resultCode, this, PLAY_SERVICES_RESOLUTION_REQUEST).show();
        } else {
            Log.e(TAG, "This device is not supported.");
            finish();
        }
        return false;
    }
    return true;
}
