Access scope using Kind Name on Google Cloud / Android Mobile Backend Starter - android

Documentation for the Google Cloud MBS states that access to stored Entities can be controlled via prefixing the KindName of that entity with strings "[public]" or "[private]" (or nothing).
https://cloud.google.com/developers/articles/mobile-backend-starter-api-reference#acfce
However attempting insertion of CloudEntities into the Datastore using KindNames that start with [public] or [private] causes an exception/error, specifically that the KindName is invalid.
This is the case both for the Backend running in Open and in Secured mode (using Google login credentials to derive the _owner field)
e.g. here I use KindName "[public]TestDB" which fails, whereas "TestDB" would not throw any exception.

04-22 19:57:54.132: E/AndroidRuntime(4690): java.lang.IllegalArgumentException: Illegal kind name: [public]TestDB

04-22 19:57:54.132: E/AndroidRuntime(4690): at com.example.package.CloudUtil.checkSync(CloudUtil.java:199)
The relevant section of code editted/compressed for brevity is:
CloudBackendMessaging cbm=_cloudfrag.getCloudBackend();
List<CloudEntity> entries=new ArrayList<CloudEntity>();
while (...) {
CloudEntity ce=new CloudEntity(_CLOUD_DB_KIND);
ce.put("fieldname", devID);
entries.add(ce);
}
_countActivity.runOnUiThread(new Runnable() {
#Override
public void run() {
cbm.updateAll(entries, handler);
}
});
Where handler is the callback and _cloudfrag is the CloudBackendFragment from the sample code.
I get the same effect using both inserts and updates, for single or multiple i.e. lists of entities at a time.
I can only think I'm misunderstanding the documentation - but it seems fairly explicit that KindNames can begin with [public] [private] etc?

Judging by the bug reports on github from others experiencing the same issue, this is a bug in Google's MBS library.
Unfortunately the response to this has been silence for months until tonight the devs posted a single commit updating the readme file to indicate this library is no longer supported and is not an official google product (despite it being pushed as a starter kit with every cloud project started from the console!).
https://github.com/GoogleCloudPlatform/solutions-mobile-backend-starter-android-client/pull/16
Looking at the source I think this access modifier feature was never actually implemented despite documentation to the contrary.

Branch.io deferred deep link missing data after install

I'm trying to get deferred deep links working on Android. I added a test device in the dashboard & reset the device data and made sure the app is uninstalled. When I click a branch.io link, it takes me to the play store as expected. I then launch the app from Android Studio onto the phone, then the logs say that Branch SDK sent a request to https://api2.branch.io/v1/install, but the problem is the response doesn't contain the original link, query params, or key value pairs I set in the dashboard. This is the JSONObject I'm receiving in onInitFinished:
{"+match_guaranteed":true,"link_click_id":"976953359423305632","+clicked_branch_link":true,"+click_timestamp":1634196720,"+is_first_session":true,"utm_source":"test-referrer"}
Where is all the other information? This doesn't include the original link, the key-value pairs, tags, etc.
For a comparison, this is what I receive in the iOS app:
["$ios_passive_deepview": "branch_passive_default", "source": "test-referrer", "+is_first_session": 1, "~channel": test-referrer, "$matching_ttl_s": 7200, "~id": 976763609660742721, "~creation_source": 1, "$one_time_use": 0, "~marketing": 1, "~referring_link": "https://myapp.test-app.link/test-referrer", "~feature": "test", "+click_timestamp": 1634249299, "+match_guaranteed": 0, "$og_description": "My app description", "$og_title": "MyApp", "+clicked_branch_link": 1, "$marketing_title": "Test Referral Link", "~tags": ["test-referrer"], "~campaign": "test"]
If I rotate the phone to recreate the Activity or reopen the app a single time, it then sends a request to https://api2.branch.io/v1/open and returns all the info I expected initially. How do I get the information after installing the app?
I'm currently testing with myapp.test-app.link, and I call Branch.enableTestMode() before Branch.getAutoInstance(this) in my custom Application class's onCreate(). I also tried with a live link and got the same result.
These are the libraries I'm using in build.grade:
implementation 'io.branch.sdk.android:library:5.0.13'
implementation 'com.google.firebase:firebase-appindexing:20.0.0'
implementation 'com.google.android.gms:play-services-ads-identifier:17.1.0'
implementation 'androidx.browser:browser:1.3.0'
I've also set up app links and the uri scheme in the dashboard as well as in the app. Using getFirstReferringParams() and getLatestReferringParams() on the first session after installing doesn't help either.
UPDATE:
Repeating the exact same testing process I described above, now the JSONObject that gets passed into onInitFinished has even less information and is claiming that I'm not clicking a branch link:
{"+clicked_branch_link":false,"+is_first_session":true}
And getFirstReferringParams() returns an empty json object.
I'm about to start looking for an alternative at this rate.
I fixed this issue by adding intent.putExtra("branch_force_new_session", true); right after this.activity.setIntent(intent); when initialising the intent. Something like this:
...
this.activity.setIntent(intent);
intent.putExtra("branch_force_new_session", true);
Branch
.sessionBuilder(this.activity)
.withCallback(branchReferralInitListener)
.reInit();
...
Look here for the branch_force_new_session reference.
The other reason for the missing data is the non-existent link alias, but it looks like it is not the case as soon as you tried with the same link in iOS.

Using ACRA with tracepot as backend

I have just finished my first android app as part of a school project ..one of my friends encountered a problem while trying to explore one of the activities in the app ..so i searched for solutions to get the crashes reports whenever they happen to fix the bugs ..i came across ACRA ..and I followed one of SO threads to setup ACRA to my app ..
RESULT: when the crashs happens the gmail app get launch in the device and the user (if he want to) he'll send the crash report by email ..Consedering not all users will want to ..i found in a comment in one of the SO threads that some developers use tracepot.
so i have used their link for integration in formUri but exploring my account on tracepot i get nothing ..is there something i am doing wrong (or if there is a better solution than using tracepot a backend , please suggest/explain or link a good tutorial, thanks!)
MyApplication.Java ( AFTER EDITING
#ReportsCrashes(
formUri = "https://collector.tracepot.com/79b1***",
reportType = org.acra.sender.HttpSender.Type.JSON,
httpMethod = org.acra.sender.HttpSender.Method.PUT,
mode = ReportingInteractionMode.TOAST,
resToastText = R.string.crash_toast_text
)
public class MyApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
CaocConfig.Builder.create()
//.errorActivity(CustomErrorActivity.class) //default: null (default error activity)
.apply();
// The following line triggers the initialization of ACRA
ACRA.init(this);
}
}

By default, if the mail config is present, Acra 4 will send via mail and nothing else.
To use both you'd have to configure the reportSenderFactories.

Codename one GoogleConnect setScope is not effective

I am using the new GoogleConnect thing and set the scope like
Login gc = GoogleConnect.getInstance();
gc.setScope("https://www.googleapis.com/auth/plus.profile.emails.read https://www.googleapis.com/auth/drive https://www.googleapis.com/auth/drive.file");
...
gc.doLogin();
However, when the access token is generated and checked in
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=(accesstoken)
, it shows
"scope": "https://www.googleapis.com/auth/plus.me https://www.googleapis.com/auth/userinfo.profile"
Is it related to any recent updates or new build hint?
I am totally lost here. It is an Android build.
Thanks.
Edited to add gc.doLogin() code, to clarify that I am NOT trying to set the scope after the access token is generated.
Same problem here, setScope only works on the simulator
"scope": "https://www.googleapis.com/auth/plus.me https://www.googleapis.com/auth/userinfo.profile",
My scopes (for reference):
google.auth.scopes=https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/plus.me email profile

Acessing Application Lifecycle Interface with AppMethod

I am using the new Embarcadero AppMethod 1.14 to do some development for Android Devices (in C++), but I cannot for the life of me figure out how to gain access to the lifecycle events (doPAuse, doResume, etc). If anyone has any how-to's links, tips or code they can share on this subject?
Here is the code I finally came up with:
TGUID guid = StringToGUID("{F3AAF11A-1678-4CC6-A5BF-721A24A676FD}"); // GUID for ApplicationEventService interface
IInterface *AEventSvc;
if (TPlatformServices::Current->SupportsPlatformService(guid)) {
AEventSvc = TPlatformServices::Current->GetPlatformService(guid);
IFMXApplicationEventService *EventSvc;
AEventSvc->QueryInterface(guid,(void**)(&EventSvc));
EventSvc->SetApplicationEventHandler(SysEventHandler);
EventSvc->Release();
}
Kudos out to Pawel Glowaki whose blog gave me the key details to getting this answer: http://blogs.embarcadero.com/pawelglowacki/2013/09/30/40067/

How can I import XML schema without network access?

I'm implementing schema validation using libxml2. The schema I'm validating against imports two other schemas with lines like:
<xs:import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.somewebsite.com/xsd/xml.xsd"/>
All three schema files are located in the same directory on the device.
This works well when the device has internet access, but fails when it does not, as libxml2 still attempts to download the imported schemas from the schemaLocation even though I'm passing in XML_PARSE_NONET.
I tried getting libxml2 to load the files locally by editing the schemaLocation attribute to xml.xsd, ./xml.xsd, and file:///data/data/com.company.appname/files/xml.xsd, but all three resulted in the same libxml2 error:
domain: 16
code: 3069 (XML_SCHEMAP_INTERNAL)
message: Internal error: xmlSchemaParse, An internal error occurred.
I also tried removing the schemaLocation attribute entirely, on the off-chance that libxml2 might search for the imported schemas alongside the original schema, but that resulted in the following error when the schema parser hit a line that referenced the imported entities:
<xs:attribute ref="xml:lang" use="required"/>
domain: 16
code: 3004 (XML_SCHEMAP_SRC_RESOLVE)
message: attribute use (unknown), attribute 'ref': The QName value '{http://www.w3.org/XML/1998/namespace}lang' does not resolve to a(n) attribute declaration.
I also looked into manually merging the three schemas into a single file, but as they use different namespaces, this is not possible.
The standard solution for this seems to be the XML catalog, but I've read through libxml2's catalog documentation, and I can't figure out how (or even whether it's possible) to add mappings that will be used by my app when deployed to a device. I think I might need to implement an xmlExternalEntityLoader, but the documentation for that is quite slim.
How can I get libxml2 to import these schemas without network access? Obviously I'd ideally like a robust solution that works with the unedited schema, but I've be content with something quick-and-dirty that involves editing the schema, like my original attempts described above.
The errors described above are from an Android device (using JNI), but I'm having similar problems on iOS, where the solution will also need to work.
One way to do this is to intercept libxml2's call to open the imported URL with a custom xmlExternalEntityLoader.
The basic code for doing this is as follows:
#include <libxml/xmlIO.h>
#include <libxml/parserinternals.h>
xmlExternalEntityLoader defaultLoader = NULL;
xmlParserInputPtr
xmlMyExternalEntityLoader(const char *URL, const char *ID,
xmlParserCtxtPtr ctxt) {
xmlParserInputPtr ret;
const char *fileID = NULL;
/* lookup for the fileID
* The documentation suggests using the ID, but for me this was
* always NULL so I had to lookup by URL instead.
*/
ret = xmlNewInputFromFile(ctxt, fileID);
if (ret != NULL)
return(ret);
if (defaultLoader != NULL)
ret = defaultLoader(URL, ID, ctxt);
return(ret);
}
int main(..) {
...
/*
* Install our own entity loader
*/
defaultLoader = xmlGetExternalEntityLoader();
xmlSetExternalEntityLoader(xmlMyExternalEntityLoader);
...
}
(Slightly adjusted from the sample code in The entities loader section of libxml2's I/O Interfaces documentation.)
