我正在向我的应用添加一个 MapFragment 并具有以下代码，改编自 map 教程:

private boolean servicesConnected() {
    // Check that Google Play services is available
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

    // If Google Play services is available
    if (ConnectionResult.SUCCESS == resultCode) {
        // In debug mode, log the status
        Log.d("Location Updates", "Google Play services is available.");
        // Continue
        return true;

    // Google Play services was not available for some reason
    } else {
        GooglePlayServicesUtil.getErrorDialog(resultCode, this, 7).show();
        return false;
    }
}

我正在使用过时的 google play 服务测试出厂重置的 Galaxy tab 10.1。因此，当我尝试打开 MapFragment 时，我调用 servicesConnected() 进行检查，正如预期的那样，我收到一个对话框，告诉我我需要 Google Play 服务。在对话框的底部有一个按钮“获取 Google Play 服务”，但是当我点击它时，它什么也没做。我的 LogCat 产生以下输出:

07-23 15:30:43.580: W/GooglePlayServicesUtil(2515): Google Play services is missing.
07-23 15:30:48.510: E/SettingsRedirect(2515): Can't redirect to app settings for Google Play services

我有以下 onConnectionFailed 方法(基本上是从 Android 开发者网站复制粘贴):

public void onConnectionFailed(ConnectionResult connectionResult) {
    /*
     * Google Play services can resolve some errors it detects.
     * If the error has a resolution, try sending an Intent to
     * start a Google Play services activity that can resolve
     * error.
     */
    if (connectionResult.hasResolution()) {
        try {
            // Start an Activity that tries to resolve the error
            connectionResult.startResolutionForResult(
                    this,
                    CONNECTION_FAILURE_RESOLUTION_REQUEST);
            /*
             * Thrown if Google Play services canceled the original
             * PendingIntent
             */
        } catch (IntentSender.SendIntentException e) {
            // Log the error
            e.printStackTrace();
        }
    } else {
        /*
         * If no resolution is available, display a dialog to the
         * user with the error.
         */
        GooglePlayServicesUtil.getErrorDialog(connectionResult.getErrorCode(), this, 7).show();
    }
}

为什么这不起作用？任何帮助都会很棒。

Here是我工作的 Android 开发页面，here也是与之相关的 SO 帖子。

我意识到我没有在设备上设置 Google 帐户，所以我设置了一个，但这没有任何区别。

这段代码对我有用:

boolean checkGooglePlayServicesAvailable() {
    final int connectionStatusCode = GooglePlayServicesUtil
        .isGooglePlayServicesAvailable(getActivity());
    Log.i(DEBUG_TAG,
    "checkGooglePlayServicesAvailable, connectionStatusCode="
    + connectionStatusCode);
    if (GooglePlayServicesUtil.isUserRecoverableError(connectionStatusCode)) {
        showGooglePlayServicesAvailabilityErrorDialog(connectionStatusCode);
        return false;
    }
    Toast t = Toast.makeText(getActivity(),
        "Google Play service available", Toast.LENGTH_LONG);
    t.show();
    return true;
}

void showGooglePlayServicesAvailabilityErrorDialog(
    final int connectionStatusCode) {
    getActivity().runOnUiThread(new Runnable() {
    public void run() {
    final Dialog dialog = GooglePlayServicesUtil.getErrorDialog(
        connectionStatusCode, getActivity(),
        REQUEST_GOOGLE_PLAY_SERVICES);
        if (dialog == null) {
                Log.e(DEBUG_TAG,
                        "couldn't get GooglePlayServicesUtil.getErrorDialog");
                Toast.makeText(getActivity(),
                        "incompatible version of Google Play Services",
                        Toast.LENGTH_LONG).show();
            }
            //this was wrong here -->dialog.show();
       }
    });
}
