Using volley for basic network operations,getting no connection handshake error when adding the project as an module.
While the module works fine in some another project.
On R&D, added retrypolicy but no use still getting the same error.
Here is my code.
https://gist.github.com/fizzysoftware/a895bc2cbd1ad9a048277859f3f23963
It could be one of these two cases:
You try to connect to an HTTP url but it's actually an HTTPS url, or
You try to connect to an HTTPS page but the certificate is not valid.
These are at least the cases I've encountered so far...
Changing the url from Https to Http will work.
In my project also same issues are faced. In Marshmallow its work suffecfully. But in Kitkat version it raised the issue
"com.android.volley.NoConnectionError: javax.net.ssl.SSLHandshakeException: Handshake failed"
For Handling this I used google's auth dependencies. Kindly add the following dependency in your Gradle
compile 'com.google.android.gms:play-services-auth:11.0.2'
And Implement the method for Installing Security Provider in Lower versions, If instalation's required
private void updateAndroidSecurityProvider(Activity callingActivity) {
try {
ProviderInstaller.installIfNeeded(this);
} catch (GooglePlayServicesRepairableException e) {
// Thrown when Google Play Services is not installed, up-to-date, or enabled
// Show dialog to allow users to install, update, or otherwise enable Google Play services.
GooglePlayServicesUtil.getErrorDialog(e.getConnectionStatusCode(), callingActivity, 0);
} catch (GooglePlayServicesNotAvailableException e) {
Log.e("SecurityException", "Google Play Services not available.");
}
}
Then call the method in your activity, before making network operations.

recently I ported my old Android game developed in Eclipse from 2011-2016, to Android Studio because I was forced to a much higher MinSdk by Google. To the following according to build.gradle:
compileSdk 30
minSdk 26
targetSdk 31
Everything worked fine after the porting, but I am not able to get the GooglePlayServices (Leaderboards, Achievements) working again.
I am able to trigger that the user signs in with it GooglePlay account. This works and I get the account and can log its name. That is working.
mGoogleSignedInAccount = completedTask.getResult(ApiException.class);
Log.e(TAG, "account: " + mGoogleSignedInAccount.getDisplayName());
But when I try open the leaderboard, so that the user can see their highscore compared to other players
LeaderboardsClient lbc = Games.getLeaderboardsClient(v.getContext(),
ApplSettings.getInstance()._mainActivity).mGoogleSignedInAccount);
Task<Intent> lbt = lbc.getAllLeaderboardsIntent();
lbt.addOnSuccessListener(new OnSuccessListener<Intent>() {
public void onSuccess(Intent intent) {
Log.d(TAG," ..onSuccess");
((Activity) (v.getContext())).startActivityForResult( intent, 9004 );
}
});
lbt.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.d(TAG,".. onFailure: "+e.toString());
}
});
I get the following error:
.. onFailure: com.google.android.gms.common.api.ApiException:
17: API: Games.API is not available on this device.
Connection failed with: ConnectionResult{statusCode=DEVELOPER_ERROR, resolution=null, message=null}
I really don't understand this error. What does it mean? It is independent of the phones I use (OnePlus6T, Samsung Galaxy S9). And of course other game apps on those phones, including my other older games app, can show Leaderboards!
What is also strange, is the following message in the GooglePlayConsole of my app in Play-GamesSevice->Configuration.
It says the 5 tasks have to be done to enable the Play-GameServices, and its states that 4 have been done, and 1 task is remaing:
Play-GameService enabling:
Create a Play GamesService project -> done
Create OAuth ConfirmationScreen in the Google Cloud Platform -> done
Create Credentials -> done
Add the SDK for Google Play-GamesServices to your production APK -> OPEN !!!
Publish Project -> done
What does point 4 mean? How to add an SDK to my games app?
Is it not enough to mention those play-service 'libraries' in the build.gradle of my app?
buildscript {
repositories {
google()
mavenCentral()
}
}
dependencies {
. . .
implementation 'com.google.android.gms:play-services-games:23.1.0'
implementation 'com.google.android.gms:play-services-measurement-api:20.0.0'
implementation 'com.google.android.gms:play-services-auth:20.4.1'
}
So I am not sure if this task (number 4) mentioned by Google as outstanding, is related to the error "Games.API is not available on this device", but it would make sense.
But still I don't understand "not available on this device"? Does not the app is build with libraries that communicate with the Google services in the cloud? What shall be missing on the device? All games app (my other very old game, and also very new apps) can without problem show leaderboards on my devices I use for testing.
I am creating an app with the use of Android Enterprise.
For that, I added dependencies in the build.gradle file.
implementation 'com.google.apis:google-api-services-androidmanagement:v1-rev84-1.25.0'
I am trying to disable uninstalling application using below code from here
try{
Policy policy = new Policy();
policy.setUninstallAppsDisabled(true);
} catch (Exception e) {
e.printStackTrace();
}
But above code is not working. No any Exception or Warning arise
What I am missing? Not able to found proper documentation that how to use Enterprise Management API.
Using the client library of the Android Management API from an Android app is not enough the manage the device the app is running on. You need to first set up the device as managed. For that you can follow the instructions in the quickstart guide.
I have a node server which uses Let's Encrypt CA and it's hosted on zeit.now.
The client is developed using react-native.
I try to connect to it using websockets.
On iOS and newer Android versions (API > 20) it connects successfully.
When running on older Android versions (both on simulator and actual devices) it never connects.
I have tried to connect using older Android version to a server that's not using Let's encrypt CA (but IS using ssl from other provider - hosted on heroku), and it also connects successfully.
So I believe there is something wrong with older Android versions and Let's encrypt certificate.
Could someone help? I have lost 5 days researching this problem and I don't know a lot about JAVA.
EDIT:
I try to connect using websocket
ws.onerror = (e) => {
// an error occurred
console.log(e.message);
};
this logs:
Connection closed by peer
and this method:
ws.onclose = (e) => {
// connection closed
console.log(e.code, e.reason);
};
logs:
undefined, undefined
I fixed it! See this comment.
Basically I needed to install the latest security fixes that are bundled with Google Play Services
I fixed this by adding the following dependency to Gradle:
implementation 'com.google.android.gms:play-services-safetynet:17.0.0'
and then calling
public void onCreate() {
super.onCreate();
try {
ProviderInstaller.installIfNeeded(this);
} catch (GooglePlayServicesRepairableException e) {
// Don't forget exception handling!
} catch (GooglePlayServicesNotAvailableException e) {
// Do something clever
}
SoLoader.init(this, /* native exopackage */ false);
initializeFlipper(this, getReactNativeHost().getReactInstanceManager());
}
I face issue with get token from firebase (push notification)
Default FirebaseApp is not initialized in this process com.ready_apps.Nebka.Business. Make sure to call FirebaseApp.initializeApp(Context) first.
even I called FirebaseApp.InitializeApp(this); in many places
MyApplication (that extend Application) , in onCreate of Activity where I call FirebaseInstanceId.Instance?.Token;
Edit: This bug has been fixed in Xamarin.Firebase version 57.1104.0-beta1.
This error seems to be present in the newer versions of Firebase for Xamarin. I am also experiencing this error as of today, using the latest stable version 42.1021.1. (The error is also present in the latest beta build).
I found that a bug report has been filed for the issue here.
As mentioned in the bug report, deleting both the /obj and /bin folders in your Android project, and/or cleaning the project in Visual Studio should fix the problem temporarily until you update any resource that would change the Resource.Designer.cs file.
Downgrading to an older version of Firebase and Google Play Services is also possible before a permanent solution is available. I did not experience this error on Firebase and Google Play Services version 32.961.0, for example.
Just Clean the solution once and run the app again.
This bug is already reported to Xamarin.
https://bugzilla.xamarin.com/show_bug.cgi?id=56108
This solution is provided in their comment thread, it might get fixed in the newer release of xamarin NuGet package.
I didnt fix it but I find walkaround this issue in debug mode only
I called this method onCreate() in activit I need to request the token
FirebaseInstanceId.Instance?.Token
here is the method
private void ConfigureFireBase()
{
#if DEBUG
try
{
Task.Run(() =>
{
var instanceId = FirebaseInstanceId.Instance;
instanceId?.DeleteInstanceId();
//Log.Debug("TAG", "{0} {1}", instanceId?.Token?.ToString(), instanceId.GetToken(GetString(Resource.String.gcm_defaultSenderId), Firebase.Messaging.FirebaseMessaging.InstanceIdScope));
});
// For debug mode only - will accept the HTTPS certificate of Test/Dev server, as the HTTPS certificate is invalid /not trusted
ServicePointManager.ServerCertificateValidationCallback += (o, certificate, chain, errors) => true;
}catch (Exception e)
{
Log.Debug("TAG", e.Message);
}
#endif
}
I'm trying to use Google cloud messaging for an android app (Target name: Google APIs, platform: 4.3, API level: 18. I implemented my GCM client by following the isntructions here: http://developer.android.com/google/gcm/client.html, and setup play services by following the steps here:
http://developer.android.com/google/play-services/setup.html#Setup, but still get the above error Most of the solutions I've found on stack overflow redirect to the above two links, or suggest that we change the dependencies {} in the gradle settings, but I'm using eclipse and don't have gradle setup.
Update: Sorry yes I'm using the emulator and not a device
Any ideas?Thanks!
If you need to provide an option for the user to update the google services you can do this:
switch (isGooglePlayServicesAvailable(this)) {
case 2: //out date
try {
GooglePlayServicesUtil.getErrorDialog(2, this, 0).show();
} catch (Exception e) {
e.printStackTrace();
}
break;
}
This will prompt an update dialog for the user to update play services
The final solution was creating a new emulator under Android 4.4.2, with the build target of the project set to Google APIs (x86 System Image). Thanks to Pedro Oliveira!
