Android - package conflicts with existing package with the same name

I set this default configuration to Gradle.

defaultConfig { applicationId "com.my.application" minSdkVersion 16 targetSdkVersion 22 versionCode 190011 versionName "2.2.1" }

And these flavors

 productFlavors { dev { applicationIdSuffix ".dev" versionCode 333333 buildConfigField "String", "ANVIL_BASE_URL", "DEBUG_URL" resValue "string", "app_name", "app name dev" signingConfig signingConfigs.releasesign } prod { buildConfigField "String", "ANVIL_BASE_URL", "PROD_URL" resValue "string", "app_name", "app name" signingConfig signingConfigs.releasesign } }

I got an application released on the Play Store with the default application identifier "com.my.application", but when I have the Play Store version installed and you want to install the "dev" application, it displays a message that says the following:

 app name dev App not installed The package conflicts with an existing package by the same name

Am I doing something wrong? I tried changing the buildCode for dev, but that didn't work either.

Any guess?

Thanks in advance.

Well, trying to install a modified version of the application through the command line, I found the following error:

 adb install ~/Desktop/app-dev-release.apk Failed to install /Users/axier/Desktop/app-dev-release.apk: Failure [INSTALL_FAILED_DUPLICATE_PERMISSION: Package com.my.application.dev attempting to redeclare permission com.my.application.permission.C2D_MESSAGE already owned by com.my.application]

So, I modified my AndroidManifest.xml file as follows:

 <uses-permission android:name="${applicationId}.permission.C2D_MESSAGE" />

Pretty bad error description for this. Hope the solution will work for someone like me in the future.

Thank you anyway.

You should look at the gradle documentation (ApplicationId versus PackageName) . Also, have you really released a version in the play store with the package name "com.my.application"? My suggestion for your problem was to put the application in ProductFlavors. Also consider fooobar.com/questions/1257056 / ... which also answers your question.

You have installed the application on your phone with the same package name. Install int before installing this.
