Android Question Compile error on android 7

[stevenindon]

Hello all,

I have been compiling my app for android 10 and 11 without problem. Now when i try to compile for my Samsung Tab - which is running on android 7.0, it prompts with below error :

What could be the possible problem? My application name is : TW.TWApp.Com

Could it be that the application name cannot consist of capital letters? * I have firebase in my app as well. Please help. Thanks.

uppercase chars in the packagename can be problematic with firebase.

What are you changing, and why, to 'compile for my Smsung Tab'?

@DonManfred : Thank you for the tips. Will have to recreate firebase+ios cert+iosprovision profile etc etc.. as all links to the name... Wheeewww....

@agraham : Did not change anything. Compiled ok for Android 10 and 11.. but error when compile for android 7. As to why, just want to make sure that the application runs in MOST phones / Tabs

I don't understand what this means if you aren't doing anything different!

Check

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

Malformed Manifest in uppercase characters in package name and Firebase services

Hi everybody I used uppercase character in one of my published games, therefore I can’t use Firebase services (cloud messaging), I get INSTALL_PARSE_FAILED_MANIFEST_MALFORMED error message while compiling. As I have more than +5M installs in Google play I can’t change package name and release...
