Namespace not specified error after Capacitor upgrade

Question

I have recently upgraded my Capacitor version to v6 and Gradle to v8.7, which has introduced a persistent namespace issue. The problem originates from the following path: node_modules/@capacitor/android/capacitor/build.gradle.

Here is the full error message:

Namespace not specified. Specify a namespace in the module's build file:/node_modules/@capacitor/android/capacitor/build.gradle. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace. If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

Steps I’ve taken so far include modifying the build.gradle files within both the app and android directories using the Android Upgrade Assistant.

I added the namespace in the build.gradle file located in the app directory and ensured that the AndroidManifest.xml file correctly declares the package.

I also removed the package-lock.json file, the node_modules directory, and the android folder, followed by reinstalling everything. However, the issue persists.

Confirmed that namespace is also added correctly in node_modules/@capacitor/android/capacitor/build.gradle

namespace "com.exmple.app" add this line in compileSdkVersion 34 below or above and use your package name — suresh madaparthi

We got exactly the same issue after upgrading to Capacitor 6. In my case, I was able to solve it by running "cap sync".

Simply superb. Normally I will use cap copy, cap sync command after every single content update before building apk. But this time I forgot to do this after upgrading capacitor. Thank you.

In Build gradle Add this line: namespace 'com.example.youapp'

android { namespace 'com.example.youapp' compileSdk 34 defaultConfig { applicationId "com.example.youapp" minSdk 24 targetSdk 34 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } }
