How to download a Google Play Games Services Saved Games Snapshot's Data, silently?

I'm trying to use Google's Saved Games feature with Google Play Games Services in my Android app. Google provides sample code how to do so:
private static final int RC_SAVED_GAMES = 9009;
private String mCurrentSaveName = "snapshotTemp";
private void showSavedGamesUI() {
SnapshotsClient snapshotsClient =
Games.getSnapshotsClient(this, GoogleSignIn.getLastSignedInAccount(this));
int maxNumberOfSavedGamesToShow = 5;
Task<Intent> intentTask = snapshotsClient.getSelectSnapshotIntent(
"See My Saves", true, true, maxNumberOfSavedGamesToShow);
intentTask.addOnSuccessListener(new OnSuccessListener<Intent>() {
#Override
public void onSuccess(Intent intent) {
startActivityForResult(intent, RC_SAVED_GAMES);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (intent != null) {
if (intent.hasExtra(SnapshotsClient.EXTRA_SNAPSHOT_METADATA)) {
// Load a snapshot.
SnapshotMetadata snapshotMetadata =
intent.getParcelableExtra(SnapshotsClient.EXTRA_SNAPSHOT_METADATA);
mCurrentSaveName = snapshotMetadata.getUniqueName();
// Load the game data from the Snapshot
// ...
} else if (intent.hasExtra(SnapshotsClient.EXTRA_SNAPSHOT_NEW)) {
// Create a new snapshot named with a unique string
String unique = new BigInteger(281, new Random()).toString(13);
mCurrentSaveName = "snapshotTemp-" + unique;
// Create the new snapshot
// ...
}
}
}
Obviously, Google wants you to use their provided intent to let the user decide which saved game to load or if a new save game should be created.
I, on the other hand, want to do this decision for the user. However, I'm unable to find a way to return a list of snapshots and to load snapshot data.
Since my game won't require to maintain more than one saved game per user I'm less interested in getting a list of snapshots without an intent (which would be an interesting solution, though) and more in loading a snapshot based on the name of the saved game, silently.
How can I load a snapshot without showing an intent?

The comment of jess leaded me to a solution that is now deprecated. However the person who posted the answer pointed out that there is also a working solution in the CollectAllTheStars sample app that is provided by Google. I was tempted to check this sample app to find out if the Google team has changed the code to fit the new way. For my amuse the comments in that sample app were describing the old deprecated way, still, but the code was changed for my luck.
Inspecting the code gave me ideas, so I came up with this solution:
String serializedSavedGameData;
public void downloadSavedGameData(final String name) {
if(snapshotsClient != null) {
snapshotsClient.open(name, true, SnapshotsClient.RESOLUTION_POLICY_MOST_RECENTLY_MODIFIED).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.e(TAG, "Error while opening snapshot: ", e);
}
}).continueWith(new Continuation<SnapshotsClient.DataOrConflict<Snapshot>, byte[]>() {
#Override
public byte[] then(#NonNull Task<SnapshotsClient.DataOrConflict<Snapshot>> task) throws Exception {
Snapshot snapshot = task.getResult().getData();
// Opening the snapshot was a success and any conflicts have been resolved.
try {
// Extract the raw data from the snapshot.
return snapshot.getSnapshotContents().readFully();
} catch (IOException e) {
Log.e(TAG, "Error while reading snapshot: ", e);
} catch (NullPointerException e) {
Log.e(TAG, "Error while reading snapshot: ", e);
}
return null;
}
}).addOnCompleteListener(new OnCompleteListener<byte[]>() {
#Override
public void onComplete(#NonNull Task<byte[]> task) {
if(task.isSuccessful()) {
byte[] data = task.getResult();
try {
serializedSavedGameData = new String(data, "UTF-16BE");
} catch (UnsupportedEncodingException e) {
Log.d(TAG, "Failed to deserialize save game data: " + e.getMessage());
}
} else {
Exception ex = task.getException();
Log.d(TAG, "Failed to load saved game data: " + (ex != null ? ex.getMessage() : "UNKNOWN"));
}
}
});
}
}
I implemented a simple resolving policy (take the newest saved game on conflicts), but I had no time to hard test all the different cases like conflicts, but it passed my simple tests so far.
Hopefully anybody can profit from this.

Share non-parcelable item between App and service

I'm looking for one way to share a non-parcelable item from my application and my current Service. This is the situation:
I have a Service to store all the media data from a camera application, photos, videos etc. The mission of this service is continue saving the media when the user go to background. When I did this in a first instance, I had a lot of SIGSEGV errors:
08-22 10:15:49.377 15784-15818/com.bq.camerabq A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x8c3f4000 in tid 15818 (CameraModuleBac)
This was because the Image item that I recover from my imageReaders are not parceable, I fix this saving the Bytebuffers from the image instead of the whole image item.
But, now I'm getting the same problem with DNG captures, because from my imageReader I got a CaptureResult item that I need to use to create a DngCreator item to write the dng image.
CaptureResults and DngCreators are not parcelables or Serializables, so I don't find a way to save my data from the application to recover it in the service if I'm in background.
I have tried to copy the reference when calling the Service and it didn't worked. Also I saw in other posts as Object Sharing Between Activities in Android and Object Sharing Between Activities in Android that I can save the item in a static reference in my application context to be able to recover it in different activities. So finally I tried this:
public class DngManager extends Application {
public static DngManager sDngManagerInstance;
protected Hashtable<String, CaptureResult> dngCaptureResults;
private static String DNG_KEY_PREFIX = "dngResult_";
public DngManager(){
super();
createDNGCaptureResults();
}
public void createDNGCaptureResults() {
dngCaptureResults = new Hashtable<String, CaptureResult>();
}
public boolean addDNGCaptureResultToSharedMem(long dateKey, CaptureResult value) {
dngCaptureResults.put(DNG_KEY_PREFIX + dateKey, value);
return true;
}
public CaptureResult getFromDNGCaptureResults(long dateKey) {
return dngCaptureResults.get(DNG_KEY_PREFIX + dateKey);
}
private boolean containsDNGCaptureResults(long dateKey) {
return dngCaptureResults.containsKey(DNG_KEY_PREFIX + dateKey);
}
public void clearDNGCaptureResults(long dateKey) {
String partKey = String.valueOf(dateKey);
Enumeration<String> e2 = dngCaptureResults.keys();
while (e2.hasMoreElements()) {
String i = (String) e2.nextElement();
if (i.contains(partKey))
dngCaptureResults.remove(i);
}
}
public static DngManager getInstance(){
if (sDngManagerInstance == null){
sDngManagerInstance = new DngManager();
}
return sDngManagerInstance;
}
}
And later I recover it in my service:
CaptureResult dngResult = ((DngManager)getApplication()).getFromDNGCaptureResults(mDngPicture.getDateTaken());
if (dngResult == null) {
return;
}
DngCreator dngCreator = new DngCreator(mCameraCharacteristics, dngResult);
path = Storage.generateFilepath(title, "dng");
file = new File(Uri.decode(path));
try {
Log.e(TAG, "[DngSaveTask|run] WriteByteBuffer: Height " + mDngPicture.getSize().getHeight() + " Width " + mDngPicture.getSize().getWidth());
OutputStream os = new FileOutputStream(file);
dngCreator.writeByteBuffer(os, mDngPicture.getSize(), mDngPicture.getDngByteBuffer(), 0);
} catch (IOException e) {
Log.d(TAG, "[DngSaveTask|run] " + e);
e.printStackTrace();
}
dngCreator.close();
Log.e(TAG, "[DngSaveTask|run] Cleaning Result from shared memory");
DngManager.getInstance().clearDNGCaptureResults(mDngPicture.getDateTaken());
MediaScannerConnection.scanFile(getApplicationContext(), new String[]{file.getAbsolutePath()}, null, null);
Anyway, it still giving me back a SIGSEGV error. What else can I try?

Get command Google now in my app

I would like to get back results in a variable of type String. The contents of what the user tells his smartphone via Google now that is: "OK google claptrap " I would like to do this so I could get back 'claptrap'. I have already searched but have been unsuccessful. I found how to return my selectable application in Google now like, for example write a note in my app but in this case the person has to say " OK google note at me claptrap " so that I can get back claptrap. It is not proceeding well … I am pretty sure that it is possible because the app "commandr" already makes it for commands as "turn on the torch".
Excuse my bad english.
Thank you in advance Good evening :D
i have create a AccessibilityService for get command google now but i should touch editText for receive the command. Help me please
public class NotificationService extends AccessibilityService {
#Override
public void onAccessibilityEvent(AccessibilityEvent event) {
System.out.println("******onAccessibilityEvent*******");
if(event.getEventType() == AccessibilityEvent.TYPE_VIEW_FOCUSED || event.getEventType() == AccessibilityEvent.TYPE_WINDOWS_CHANGED) {
System.out.println(" NAME : " + event.getClassName());
System.out.println(" NAME PCK : " + event.getPackageName());
System.out.println(" SOURCE : " + event.getSource());
System.out.println(" TEXT : " + event.getText());
}
}
private String RecupCommandGoogle(AccessibilityEvent mEvent, AccessibilityNodeInfo mSource) {
if (mSource != null & mEvent.getClassName().equals("android.view.View")) {
return String.valueOf(mSource.performAction(AccessibilityNodeInfo.ACTION_SELECT));
}
return null;
}
#Override
protected void onServiceConnected() {
System.out.println("onServiceConnected");
AccessibilityServiceInfo info = new AccessibilityServiceInfo();
info.eventTypes = AccessibilityEvent.TYPE_WINDOWS_CHANGED | AccessibilityEvent.TYPE_VIEW_FOCUSED ;
info.packageNames = new String[] {"com.google.android.launcher" , "com.google.android.googlequicksearchbox"};
info.feedbackType = AccessibilityEvent.TYPES_ALL_MASK;
info.notificationTimeout = 100;
setServiceInfo(info);
}
#Override
public void onInterrupt() {
System.out.println("onInterrupt");
}

How to extract a value from a facebook invite friends onComplete() response

I am implementing Facebook friends invite in my android app and I need to get to how many friends user sent app request so that I can award him some points.
What I have done so far is as below
WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(this,
sessiob, params)).setOnCompleteListener(
new OnCompleteListener() {
#Override
public void onComplete(Bundle values,FacebookException error) {
if (error != null) {
} else {
final String requestId = values.getString("request");
final String[] requestArr1 = values.getStringArray("to");
if (requestId != null) {
Log.e("RequestId1",requestId + "\n" + values.toString());
else {
Toast.makeText(Login.this,"Request cancelled", Toast.LENGTH_SHORT).show();
}
}
}
}).build();
And the Bundle value I am getting is Bundle[{to[0]=808411111111111,to[1]=151584774222222, request=879734911111111}]
While my above code final String requestId = values.getString("request"); working fine however values.getStringArray("to"); giving me Null.
I want to know value "to" inside the Bundle is a StringArray or not and if yes then what's wrong in my extraction process.

Android Facebook Unsupported post request error

I am working on a Facebook application and am currently trying to have my app tag one of the user's friends. I almost have it working 100%, except when it is supposed to be tagging the person, I instead get an error message that follows:
{"error":{"message":"Unsupported post request.","type":"GraphMethodException","code":100}}
The user and photo IDs are for sure correct, that is not the issue. Otherwise, I'm not sure what else could be causing this error. Code is below for reference. Thanks much!
public void setTag() {
String relativePath = Constants.photoID + "/tags/" + Constants.userID;
Bundle params = new Bundle();
params.putString("x", "5");
params.putString("y", "5");
Constants.mAsyncRunner.request(relativePath, params, "POST", new TagPhotoRequestListener(),
null);
}
public class TagPhotoRequestListener extends BaseRequestListener {
#Override
public void onComplete(final String response, final Object state) {
if (response.equals("true"))
{
String message = "User tagged in photo at (5, 5)" + "\n";
message += "Api Response: " + response;
Log.i("TagPhotoRequestListener", message);
}
else
{
Log.w("TagPhotoRequestListener", "User could not be tagged.");
}
}
public void onFacebookError(FacebookError e) {
Log.w("TagPhotoRequestListener", "Facebook Error: " + e.getMessage());
}
}
EDIT: Here is my code for posting of a picture and getting the photoID. For testing purposes it's just a single photo from my sdcard.
public void postPhoto() {
byte[] data = null;
Bitmap bi = BitmapFactory.decodeFile("/mnt/sdcard/Download/KathleenSchedule.jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();
Bundle params = new Bundle();
params.putString(Facebook.TOKEN, Constants.mFacebook.getAccessToken());
params.putString("method", "photos.upload");
params.putByteArray("picture", data);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(Constants.mFacebook);
mAsyncRunner.request(null, params, "POST", new PhotoUploadListener(), null);
}
public class PhotoUploadListener extends BaseRequestListener {
#Override
public void onComplete(final String response, final Object state) {
try {
// process the response here: (executed in background thread)
Log.d("PhotoUploadListener", "Response: " + response.toString());
JSONObject json = Util.parseJson(response);
System.out.println(response);
final String photo_id = json.getString("pid");
Constants.photoID = photo_id;

Ok, now your problem is clear.
You are using the photos.upload method which is deprecated:
We are in the process of deprecating the REST API, so if you are
building a new application you shouldn't use this function. Instead
use the Graph API and POST to the photos connection of the User object
Because you are using an old method, you're getting and old response type.
Switch to using the graph api way, and you should get the photo id in the response.
