(27-07-2026, Saat: 17:41)Mr.X Adlı Kullanıcıdan Alıntı: Merhaba,

https://mvnrepository.com/artifact/com.android.billingclient/billing/8.0.0
Bu linkten 8 sürümü ve daha üzeri için aar dosyasını edinebilirsiniz. Overview altındaki Files kısmında aar ve pom formatları bulunmakta.

[PAClient Error] Error: E8712 C:\Users\xxx\DELPHI\Rad Studio 12\xxx\xxxx\Android64\Debug\xxxx\AndroidManifest.xml:74:81-102 Error:
[PAClient Error] Error: E8712 Attribute meta-data#com.google.android.play.billingclient.version@value value=(7.1.1) from AndroidManifest.xml:74:81-102
[PAClient Error] Error: E8712 is also present at AndroidManifest.xml:24:13-34 value=(8.0.0).
[PAClient Error] Error: E8712 Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:74:9-105 to override.

(28-07-2026, Saat: 00:16)emailx45 Adlı Kullanıcıdan Alıntı: Try this:
1) in AndroidManifest.template.xml remove the complete Billing 7.1.1 definition ( to avoid use this versions by default )
->> <meta-data android:name="com.google.android.play.billingclient.version" android:value="7.1.1" />

2) see on AndroidManifest.template.xml if exist this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools"     <--------------------------
         package="%package%" ...>

3) now, look this line is exists:

<meta-data android:name="com.google.android.play.billingclient.version"
          android:value="8.0.0"
          tools:replace="android:value" />      <------------------------------------

4) if persisting error:
4.1) try re-save your manifest is necessary:  Delphi em Project > Options > Application > Entitlement List or Version Info
---> try change any thing and save it again!!! REBUILD app = force new changes in AndroidManifest.template.xml
4.2) do the items 1..3 above!

Tip: check the "AndroidManifest.xml" file in your app's build folder (within the final production executable directory) and look for everything related to billing settings; this way, you can see what is being injected during the merge process: (the Manifest Template) + ( the final manifest resulting from your choices ).

open a CMD console ( if need use as Admin, normally not need ) and try install your app to catch the stack info...
--->>   adb logcat -s AndroidRuntime FMX

NOTE: you can use the Android Studio to catch the logs... if you want! just open it and see the "Log" tab

see the attached files: by Gemini for tests ...
