Creating an Android Activity Context in python with pyjnius

I'm working on importing braintrees drop-in UI payment method into my python kivy app with the following code.
from jnius import autoclass
from jnius import cast
from android import activity
Intent = autoclass('android.content.Intent')
PythonActivity = autoclass('org.renpy.android.PythonActivity')
DropInRequest = autoclass('com.braintreepayments.api.dropin.DropInRequest')
#Global instance
instance = None
REQUEST = 1
RESULT_OK = 1
def onBraintreeSubmit(token):
global instance
def on_activity_result(request, response, data):
global instance
if request == REQUEST:
print response
if response == RESULT_OK:
result = instance.getParcelableExtra(instance.EXTRA_DROP_IN_RESULT)
nonce = result.getPaymentMethodNonce()
print nonce
return nonce
activity.bind(on_activity_result=on_activity_result)
instance = DropInRequest()
instance.clientToken(token)
intent = instance.getIntent(activity.this)
PythonActivity.mActivity.startActivityForResult(intent,REQUEST)
Which is trying to mimic this Java code
DropInRequest dropInRequest = new DropInRequest()
.clientToken(mClientToken);
startActivityForResult(dropInRequest.getIntent(context), DROP_IN_REQUEST);
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == DROP_IN_REQUEST) {
if (resultCode == Activity.RESULT_OK) {
DropInResult result = data.getParcelableExtra(DropInResult.EXTRA_DROP_IN_RESULT);
String paymentMethodNonce = result.getPaymentMethodNonce().getNonce();
// send paymentMethodNonce to your server
} else if (resultCode == Activity.RESULT_CANCELED) {
// canceled
} else {
// an error occurred, checked the returned exception
Exception exception = (Exception) data.getSerializableExtra(DropInActivity.EXTRA_ERROR);
}
}
}
My problem is I need to send a Context to the getIntent function of the DropInRequest class but I can't figure out how to make an Activity Context with python-for-andriod and pyjnius. Java method of getIntent below.
public Intent getIntent(Context context) {
return new Intent(context, DropInActivity.class)
.putExtra(EXTRA_CHECKOUT_REQUEST, this);
}
I think I need to include this to my manifest and use com.braintreepayments.api.BraintreeBrowserSwitchActivity as my activity but I'm not sure how to get the context from it.
<activity android:name="com.braintreepayments.api.BraintreeBrowserSwitchActivity"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="${applicationId}.braintree" />
</intent-filter>
</activity>
Which I think should call this class which is a BrowserSwitchActivity which I would need to get the context from the BrowserSwitchActivity
package com.braintreepayments.api;
import com.braintreepayments.browserswitch.BrowserSwitchActivity;
/**
* Helper Activity that captures the response when browser switch completes.
*/
public class BraintreeBrowserSwitchActivity extends BrowserSwitchActivity {
}
Which ends up here which extends the class onto an Activity Class
package com.braintreepayments.browserswitch;
import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.support.annotation.Nullable;
/**
* singleTask
* Activity used to receive the response from a browser switch. This Activity contains no UI and
* finishes during {#link Activity#onCreate(Bundle)}.
*/
public class BrowserSwitchActivity extends Activity {
private static Uri sReturnUri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sReturnUri = null;
if (getIntent() != null && getIntent().getData() != null) {
sReturnUri = getIntent().getData();
}
finish();
}
/**
* #return the uri returned from the browser switch, or {#code null}.
*/
#Nullable
public static Uri getReturnUri() {
return sReturnUri;
}
/**
* Clears the return uri.
*/
public static void clearReturnUri() {
sReturnUri = null;
}
}
So I'm stuck on how do I get the context from this Activity?
Update I've changed my python code perform the DropInRequest.getIntent() method outside of java inside my python code with this code.
from jnius import autoclass
from jnius import cast
from android import activity
from kivy.context import get_current_context
context = autoclass('android.content.Context')
Intent = autoclass('android.content.Intent')
Uri = autoclass('android.net.Uri')
PythonActivity = autoclass('org.kivy.android.PythonActivity')
DropInRequest = autoclass('com.braintreepayments.api.dropin.DropInRequest')
BrowserSwitchActivity = autoclass('com.braintreepayments.api.BraintreeBrowserSwitchActivity')
#Global instance
instance = None
REQUEST = 1
RESULT_OK = 1
def onBraintreeSubmit(token):
global instance
def on_activity_result(request, response, data):
global instance
if request == REQUEST:
print response
if response == RESULT_OK:
result = instance.getParcelableExtra(instance.EXTRA_DROP_IN_RESULT)
nonce = result.getPaymentMethodNonce()
print nonce
return nonce
currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
context = cast('android.content.Context', currentActivity.getApplicationContext())
activity.bind(on_activity_result=on_activity_result)
instance = DropInRequest()
instance.clientToken(token)
mapintent = Intent()
mapintent.setClassName(context,'com.braintreepayments.api.dropin.DropInRequest')
mapintent.putExtra("com.braintreepayments.api.EXTRA_CHECKOUT_REQUEST","EXTRA_CHECKOUT_REQUEST")
currentActivity.startActivityForResult(mapintent,REQUEST)
and added this to my manifest
<activity android:name="com.braintreepayments.api.dropin.DropInRequest" >
</activity>
I seem to be making progress and when I run the App I get this Error.
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{org.test.myapp/com.braintreepayments.api.dropin.DropInRequest}: java.lang.ClassCastException: com.braintreepayments.api.dropin.DropInRequest cannot be cast to android.app.Activity
I've traced it back and DropInRequest extends Parcelable not activity...

To create a context with pyjnius you want to cast it like this.
PythonActivity = autoclass('org.kivy.android.PythonActivity')
currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
context = cast('android.content.Context', currentActivity.getApplicationContext())

App Crashes On Clicking To Start Location Update

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'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.

After a long struggle I found my own solution to the above question. Facebook have released their new SDK recently to enhance the level of security. There are a few requirements to use facebook SDK in your app.
The app should be sent for submission and needs to be approved by facebook to be use inside facebook, to enable your own app to show friends details, access locations and other special permissions The approval formalities are similar to the ones for app store in Google Play.
The application must be listed in Google Play, or you may be able to integrate it as a test user (i.e like beta testing in Google Play).
The application should have a proper package name, launching activity, domain name, website url and email.
The app id registered must match with an app name and hash key that must be generated for a user developing on different machines
The basic application information, including screenshots, description, and app logo needs to be added
Once after the successful approval, an "active" symbol will be displayed near your app name.
I hope this will be useful for others!!!
More information on Facebook site.

After spending a good number of hours trying to resolve this, I would like to add the following for anyone still looking:
The only friends you will see in the list with user_friend permissions is other users that have logged in and approved your app. I.e. if no-one else is using it, you will se noone in the list (I know, if you read it all, this is obvious)
The easiest way of testing this is to set up a test app, add test users in the dev interface for facebook under "Roles", make sure that the test users are friends and then log in with each use on your app. Only then will they show up in the list.
Unless you ask for it specifically, your app will not have the user_friends permission (you do not, however, need to review this with Facebook as it is part of the basic permissions) - I added it to the onCreateView in the Splash Segment (from the Scrumptios/Login sample in the SDK) like this:
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList("user_friends"));
Use the Facebook test user interface to login on facebook as your test user to validate that they have been accepting the correct permissions (under apps).

In-App-Billing - BillingHelper no fully instantiated

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.
