[Solved] Manifest merger failed with multiple errors, see logs

Manifest merge failed with multiple errors, see logs solution

In component-based development, when testing a single component, such problems sometimes occur in compilation

Simulate with my project:

The current test is lib_news
lib_news requires webView of lib_web

lib_news build gradle

if (isRelease) {
    apply plugin: 'com.android.library'
} else {
    apply plugin: 'com.android.application'
}

apply plugin: 'org.jetbrains.kotlin.android'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-parcelize'

android{
	……
	defaultConfig {
       ……
        kapt {
            arguments {
                arg("AROUTER_MODULE_NAME", project.getName())
            }
        }
        buildConfigField("boolean", "isRelease", String.valueOf(isRelease))

    }
	sourceSets{
        main {
            if (isRelease) {
                //if library，then compile AndroidManifest.xml in manifest
                manifest.srcFile 'src/main/manifest/AndroidManifest.xml'
            } else {
                //if application, then compile theAndroidManifest.xml in the home directory.
                manifest.srcFile 'src/main/AndroidManifest.xml'
            }
        }
    }
    ……
	dependencies{
		……
		implementation project(path: ':lib_web') //import lib_web
	}
	
}

project config.gradle

ext{
    isRelease = false
    //isUseWeb = true Comment first, the general configuration file is only configured with isRelease
	……
}

lib_web build.gradle

if (isRelease) {
    apply plugin: 'com.android.library'
} else {
    apply plugin: 'com.android.application'
}

apply plugin: 'org.jetbrains.kotlin.android'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-parcelize'

android{
	……
	defaultConfig {
       ……
        kapt {
            arguments {
                arg("AROUTER_MODULE_NAME", project.getName())
            }
        }
        buildConfigField("boolean", "isRelease", String.valueOf(isRelease))

    }
	sourceSets{
        main {
            if (isRelease) {
                manifest.srcFile 'src/main/manifest/AndroidManifest.xml'
            } else {
                manifest.srcFile 'src/main/AndroidManifest.xml'
            }
        }
    }
    ……
	dependencies{
		……
	}
	
}

In general, we only set isrelease to determine whether a single component test or integrated compilation
so the test lib_news, directly change isrelease to false, and also lib_web will also become Application, which is equivalent to us in lib_news importing Application instead of Library, will involve the problem of  androidmanifest.xml

Show me androidmanifest.xml
lib_web component mode
Lib_ Web integration mode

Solution:

project config.gradle
add a isuseweb to identify the lib_web to be used in the componentization mode

ext{
    isRelease = false
    isUseWeb = true 
	……
}

Modify lib_webbuild.gradle

if (isUseWeb) {
    apply plugin: 'com.android.library'
} else {
    apply plugin: 'com.android.application'
}
android {
	……
	defaultConfig {
		……
		buildConfigField("boolean", "isUseWeb", String.valueOf(isUseWeb))
	}
	……
	sourceSets{
        main {
            if (isUseWeb) {
                manifest.srcFile 'src/main/manifest/AndroidManifest.xml'
            } else {
                manifest.srcFile 'src/main/AndroidManifest.xml'
            }
        }
    }
	
}
