In-App-Billing - BillingHelper no fully instantiated - java

What I try to do
Hello Guys, I'm trying to create some In-App-Products for my App, its for donation use. Because im giving away free musik of my friend - he raps. Whatever, I created 5 In-App Products on my developer-account:
donate_small
donate_midsmall
donate_medium
donate_large
donate_xlarge
This are the reference key's I generated there. They are saved and published. Now if written a In-App-Service over this tutorial: In-App Easy Tutorial. The Code seems to work perfect, there are no errors and when i compile the demo-code it works. But when I try it I get allways this error:
12-06 14:23:49.400: E/BillingService(4719): BillingHelper not fully instantiated
Question
So what do I need to change the the user can choose the diffrent in-app-products? Do I need to declare them somewhere?? Also if you have a great tutorial for me, where this stuff is all well describen and fully working, please tell me.
This are the Classes I use for my In-app-service:
de.stepforward
ChannelActivity
SplashActivity
de.stepforward.billing
AppMainTest.class -> This is my Activity
BillingHelper.class
BillingReceiver.class
BillingSecurity.class
BillingService.class
C.class
de.stepforward.billing.util
Base64.class
Base64DecoderException.class
For the moment I'll provide you the Code of my BillingHelper and Activity, if you need more Code just tell me.

If you take a look at this method:
private static boolean amIDead() {
if (mService == null || mContext == null) {
Log.e(TAG, "BillingHelper not fully instantiated");
return true;
} else {
return false;
}
}
That log is printed when your Service is null or your context. Aaaand your service is null when:
protected static void instantiateHelper(Context context, IMarketBillingService service) {
mService = service;
mContext = context;
}
instantiateHelper is not called aaand
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
Log.i(TAG, "Market Billing Service Connected.");
mService = IMarketBillingService.Stub.asInterface(service);
BillingHelper.instantiateHelper(getBaseContext(), mService);
}
is called when your Service is connected, and I can see you attempt to connect to the service like this:
startService(new Intent(mContext, BillingService.class));
SO:
Have you declared the service in your manifest?
<application ...
<service android:name=".BillingService" />
...
</application>
EDIT
I was right :-) It's just your service tag is outside your application tag.

I am trying to implement oauth2 to enable users to login with Reddit. I have created my app on reddit with the appropriate redirect uri.
What I did:
A MainActivity with a login button. Clicking the login button, starts the authorization flow. To create the authorization request, we need to pass a pending intent that the library uses to call the appropriate component that we want it to call after authorization is successful.
Problem:
When the pending intent is made using an implicit intent (setting only action string while creating intent), the library gets a cancelled exception while invoking the pending intent. I have mentioned the action string in the intent filter for the MainActivity in manifest file also.
What I have tried:
1. I tried creating pending intent using an explicit intent (defining the activity class I want to open while creating intent), my activity's onStart is getting called with the correct intent.
2. I tried by directly invoking the pending intent (with implicit intent) from the activity itself and it got called successfully.
Observation:
1. If I use an older version of the library (v0.2.0), the pending intent with implicit intent works fine.
Current version of OpenId AppAuth library - 0.7.1

In case anybody else stumbles upon this issue.
Use the example app within app-auth android github project.
Don't use Google CodeLabs app-auth example! The code from the question above is from Google CodeLabs, it is very old and no longer works (state at July 2020).
I did the same mistake, app-auth links codelabs on their own page/readme, so I started using codelabs code and ended up with lots of problems and errors.
The new app-auth version 0.7.x uses a json configuration file and the example app shows how to handle errors around pending intents etc. .

I am developing an app that uses fingerprint authentication to send the location of user over certain duration ex 30 mins in form of intervals of 10 mins. i have used certain code to develop the app. But app crashes on clicking start update button.
Note : Summary of app crash says java.lang.SecurityException: Client must have ACCESS_Fine_LOCATION permission to request PRIORITY_HIGH_ACCURACY locations.

minSdkVersion 23 targetSdkVersion 24
Targeting SDK 23+ require you support Runtime Permissions. Your manifest is <uses-permission>s are irrelevant in such case (and can be removed if you not targetting lower SDKs). As you have no support for Runtime Permissions your app is not granted GPS access hence the crash with SecurityException.
Docs: https://developer.android.com/training/permissions/requesting.html
Quick solution: if you can, lower targetSdk (and minSdk) below 23. If you for any reason cannot, you must have Runtime Permissions implemented. There are some libs helping with the task - just google for it.

I am currently developing an Android App, which integrates Google Calendar in it. As we know if we wanted to choose an activity to be the starting activity, we just add the "intent-filter" thingy. I added at my Landing Page activity but when I debug on Emulator, it will auto add the "intent-filter" at my Google Calendar activity part and comment out the one I added at my Landing Page.
This is the code at AndroidManifest.xml
<activity
android:name="com.example.dylicious.mydoctors.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity
android:name="com.example.dylicious.mydoctors.ViewDocActivity"
android:label="#string/title_activity_view_doc" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.ViewDoctorProf"
android:label="#string/title_activity_view_doctor_prof" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.StorePatientProfile"
android:label="#string/title_activity_store_patient_profile" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.ViewPatientProfile"
android:label="#string/title_activity_view_patient_profile" >
</activity>
<activity
android:name="com.example.dylicious.mydoctors.AppointmentActivity"
android:label="#string/title_activity_appointment" >
<!--<intent-filter>-->
<!--<action android:name="android.intent.action.MAIN" />-->
<!--<category android:name="android.intent.category.LAUNCHER" />-->
<!--</intent-filter>-->
</activity>
This is the one I edited, AppointmentActivity is the Google Calendar part. I kept commenting out and delete the part in AppointmentActivity and clean solution and etc. but it doesn't work anything. Just want to check if I had miss out anything as I'm just a newbie in the Android App Development field. Thanks a bunch in advance!

Thanks!!

omit the intent-filter in your AppointmentActivity AndroidManifest file declaration. since calling action android:name="android.intent.action.MAIN" which defines the main entry point in your application and android:name="android.intent.category.LAUNCHER" means that the entry point should be listed in the application launcher, so you see there can't be 2 main entry points in the application.

I'm trying to make a web app with push notifications. I'm using server key with no ip adress filtering so any ip is allowed (when I was adding my public shared ip from my server I was getting a 404 forbiden error...)
Now it looks like it works, when I send a message I get this :
{"multicast_id":768704xxxxx3856470,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1430054xxxxxx71%60cd63d3f9fd7ecd"}]}{"registration_ids":["APAxxxea-Q0s5pbFZHpSu4BfKdabxxxxxxxxWjPGItVSc54U6_t7WsJme5Z5UjYldhry66rTHk95CUcRR7m2iAtfvPgTklbWlHn4YiDZi1Qxxxxxxxg9iz5jKMPiulvIQTTM5F16THVjw"],"data":{"message":"New content available!"}}
But I never receive a push in my device. I've been following tutorials form google and also form StackOverflow answers, but I'm still very noob in android and I'm sure there is something wrong in my code and I can't figure out what it is, any help would be greatly appreciated.

It will be hard to find the real solution without fixing your BroadcastReceiver implementation first.
It looks like you are following a deprecated sample. In the manifest, you no longer need the com.google.android.c2dm.intent.REGISTRATION action. Also, your receiver tag/entry should be outside the activity tag, and it should have an intent filter (your intent filter is outside the receiver tag).
Hope this leads you to a solution. You might want to follow this sample code instead.

have you added the
