Android Gradle: install all build types on one device

Question

How can I configure my project to be able to install the debug version along with the release version when using GCM, ContentProvider, AccountType? (without flavoring)

I keep getting errors like: INSTALL_FAILED_CONFLICTING_PROVIDER or INSTALL_FAILED_DUPLICATE_PERMISSION

Answer 1

Installing apug debug and apk release on the same device is complicated if you use only build types and not flavors ( Why Build types and not flavors )

( ), , applicationIdSuffix build type applicationId, flavors

• GCM

applicationIdSuffix, , BuildConfigField resValue Gradle.

, , ​​ ( aosp tracker) abortOnError false, .

build.gradle

project.ext {
    defaultApplicationId = "com.myapp.package"

    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId defaultApplicationId

        manifestPlaceholders = [ applicationIdWithSuffix: "${applicationId}" ]

        buildConfigField "String", "ACCOUNT_TYPE", "\"${applicationId}\""
        buildConfigField "String", "AUTHORITY", "\"${applicationId}.provider\""

        resValue "string", "account_type", "${applicationId}"
        resValue "string", "authority", "${applicationId}.provider"
    }
    buildTypes {
        debug {
            applicationIdSuffix ".debug"
            debuggable true

            manifestPlaceholders = [ applicationIdWithSuffix: defaultApplicationId + ".debug" ]

            buildConfigField "String", "ACCOUNT_TYPE",  "\"${defaultApplicationId}.debug\""
            buildConfigField "String", "AUTHORITY", "\"${defaultApplicationId}.debug.provider\""

            resValue "string", "account_type", "${defaultApplicationId}.debug"
            resValue "string", "authority", "${defaultApplicationId}.debug.provider"
