KivMob android.ndk version

[pihash252]

I'm trying to build my Kivy Android app apk via Colab and wanted to include KivMob in my app. I wanted to know the following:

Is android.gradle_dependencies = 'com.google.firebase:firebase-ads:10.2.0' version all right or do I need to change it according to #118

Also, android.ndk version 19b is mentioned in regard to KivMob ad display to be added in builder.spec file, but Colab supports a minimum version of 23b. Is it going to be a problem or KivMob is going to work fine even with the latter?

I've understood the rest, if you could just clarify the above because even after trying everything no banner ad is showing whereas there are no errors showing in the logcat either.

try in buildozer :

android.permissions = INTERNET, ACCESS_NETWORK_STATE
android.api = 31
android.sdk = 24
android.ndk = 23b
android.gradle_dependencies ='com.google.firebase:firebase-ads:15.0.0'
p4a.branch = master
android.meta_data = com.google.android.gms.ads.APPLICATION_ID=ca-app-pub-3940256099942544~3347511713

I can replace the APPLICATION_ID with the one I received after making my Admob account, right?

[diogokravetz]

this is google admob test id so it only shows test ads, to start monetizing admob you must add your app to google admob and create ad unit, after that until implementation instructions and copy id of application after that replace the APPLICATION_ID with the application id .

I've been trying to include ads into my app but haven't been successful yet. Everything in the logcat seems normal with no errors and I have provided the code and spec file above. Kindly take a look and tell me what am I doing wrong. Also, since I'm directly calling from the kivmob.py file I haven't included it in the buildozer.spec requirements list. Let me know if that can be a problem although no errors/warnings were thrown regarding that either.

[diogokravetz]

I'm a little out of time to test the application, but a few possible solutions: compile the app with test ads just to see if the ads will show, i believe if you compile the app with your admob banner id without having signed the app it will not show the ads About kivmob being included directly is no problem as long as you are using the most current version of the file, check that too. If that doesn't work, compile it with the code:

from kivmob import KivMob, TestIds

from kivy.app import App
from kivy.uix.label import Label

class BannerTest(App):
""" Displays a banner ad at top of the screen.
"""

def build(self):
    self.ads = KivMob(TestIds.APP)
    self.ads.new_banner(TestIds.BANNER, top_pos=True)
    self.ads.request_banner()
    self.ads.show_banner()
    return Label(text='Banner Ad Demo')

if name == "main":
BannerTest().run()

to see if the problem is in your implementation code or buildozer.speec

[pihash252]

All right. I'll try that. But can you explain further

i believe if you compile the app with your admob banner id without having signed the app it will not show the ads

I thought I already signed my app and everything when I made my account there and also received a mail saying "my account is now approved, that the ad serving is enabled and I'm all set and ready to go".

Kindly let me know if there's anything else left to be done, and how.

[diogokravetz]

Hello, when I talk about signing the app, it's with jarsigner

[diogokravetz]

cry a .jks key with:
keytool -genkey -v -keystore *****.jks -keyalg RSA -keysize 2048 -validity 10000 -alias *****

keep this key because you will always compile application with this key

run the commands:

P4A_RELEASE_KEYSTORE="****.jks"
export P4A_RELEASE_KEYSTORE_PASSWD="Your password"
export P4A_RELEASE_KEYALIAS_PASSWD="Your password"
export P4A_RELEASE_KEYALIAS="Your keyalias"

compile your app

Sign your app with :

jarsigner -verbose -sigalg SHA256withRSA -digestalg SHA-256 -keystore ****.jks your.abb yourkeyalias

Since you are using colab use ! before commands

[pihash252]

Right. Understood. Thank you very much.
