Reference Error when adding interstitial and banner ad

[SivaramNalliboyana]

I am implementing banner and interstitial ads with kivmob. When I only add banner ads, and not interstitial ads, the programm is working. When I only add interstitial ads and no banner ads, the programm is working too.I can see the ads on my phone. But when I add both of them I am getting the error in logcat: Reference Error- weakly referenced object no longer exits. Another thing to mention is that it worked yesterday perfectly, but somehow today it is not working and I did not change any code. It would be great if anybody could help me This is my code

This is the error

[SivaramNalliboyana]

Edit: I don't know why but when I implement only one ad the error is coming too. Now I can see the banner ad but the app immediately closes. Without the ad, the app is working

[akgupta0777]

This is because you created two same ad instances in your code.You are allowed to create One Ad Instance. If you want to create multiple ad instance then give them some other name.

delete self.ads = KivMob("ca-app-pub-XXXXXXXXXXXX") self.ads.add_test_device("*****")

that will fix error

[SivaramNalliboyana]

No succes, I also reinstalled everythink but it is not working Here is my full code, maybe I did something wrong in the py file `class MainApp(App):

def build(self):
    return GUI

def change_screen(self,screen_name):
    # get the screen manager from the kv file
    screen_manager = self.root.ids['screen_manager']
    screen_manager.current = screen_name
    # screen_manager = self.root.ids

def on_start(self):
    self.ads = KivMob("ca-app-pub-***************")
    self.ads.new_interstitial("ca-app-pub-*************")
    self.ads.add_test_device("***********")
    self.ads.request_interstitial()
    self.ads.new_banner("ca-app-pub-************",top_pos=False)
    self.ads.request_banner()
    self.ads.show_banner()
    from kivy.base import EventLoop
    EventLoop.window.bind(on_keyboard = self.hook_keyboard)

def hook_keyboard(self,window,key,*largs):
    if key == 27:
        # write whatever u want
        self.change_screen("home_screen")
        return True
def on_resume(self):
    self.ads.request_interstitial()

MainApp().run() ` Could anybody please check and see. Now I even cant display one ad

[akgupta0777]

Writing all the ads related code under build method may fix the errors As the objects and ad requests will be sent as soon the app starts.

[akgupta0777]

Because build method is called only once and is used for initializing the app.

[MichaelStott]

@GrandmasterSivaram It's difficult to say. You are trying to present the ad immediately after calling request_banner/interstitial, so it's possible that it hasn't loaded yet. Can you share your logcat output?

[SivaramNalliboyana]

Hi michael could you show me a sample py file how I could write it. Because I just copied from the docs and it worked for one day. . Ya sure I will show the logcat output. Thank u for the help

[SivaramNalliboyana]

this is my logcat output. As you can see at the end i have the error reference error my_log.txt

[akgupta0777]

Please add buildozer.spec too for resolving this issue

-----------------------------------------------------------------------------

List as sections

#

You can define all the "list" as [section:key].

Each line will be considered as a option to the list.

Let's take [app] / source.exclude_patterns.

Instead of doing:

#

[app]

source.exclude_patterns = license,data/audio/.wav,data/images/original/

#

This can be translated into:

#

[app:source.exclude_patterns]

license

data/audio/*.wav

data/images/original/*

#

-----------------------------------------------------------------------------

Profiles

#

You can extend section / key with a profile

For example, you want to deploy a demo version of your application without

HD content. You could first change the title to add "(demo)" in the name

and extend the excluded directories to remove the HD content.

#

[app@demo]

title = My Application (demo)

#

[app:source.exclude_patterns@demo]

images/hd/*

#

Then, invoke the command line with the "demo" profile:

#

buildozer --profile demo android debug

[akgupta0777]

I have gone through the logs and buildozer and found a Warning in the log which says

Base provider unknown I am guessing that you are running your app on a android phone that is below android version 5.0 Is that correct??

[SivaramNalliboyana]

Hi no my android version is 7.0. Do you guys think that my code is correct,because when yes it should be a problem with my phone,

[akgupta0777]

Recheck requirements check your whole code if you imported any other module and didn't reference it in buildozer.spec requirements line

And then do a clean build by this command buildozer android clean

[SivaramNalliboyana]

after clean building half way I get the error : Error while finding module specification for cython.Build.Cythonize. And I already have cython. I get the erro beacause of jnius

[akgupta0777]

Update all dependencies one more time by sudo apt-update Then rebuild app by buildozer android debug

Moreover this is not a kivmob issue By the way this is a python issue.

[MichaelStott]

@GrandmasterSivaram Just checking, are you still having issues here?

[SivaramNalliboyana]

unfortunately yes

[SivaramNalliboyana]

Closing it now. Because I think it was issue of my code. My another app is working with banner ads
