Answer 1

i have faced similar situations.

possible scenarios:

1. you didn't change applicationId in app/gradle .

Solution: In that case, change applicationId .

2.you have a defined a provider for facebook(or something similar) in AndroidManifest.xml like android:authorities="com.facebook.app.FacebookContentProviderXXXX .

Solution: Comment out that provider for testing or add different ids for providers for different build variants.

首先，您在清单文件中更改软件包名称，然后将更改后的软件包名称粘贴到applicationId位置的build.gradle（应用程序级别）
