添加依赖后出现com.google.android.gms.internal.zzbck类找不到错误求助

Hey there! Let's troubleshoot that annoying cannot access zzbck error you're seeing after adding those two dependencies. Here's what's going on and how to fix it:

This error pops up due to two key dependency conflicts in your project:

1. Mismatched Android Support Library versions: You're mixing 26.1.0 (for most support components like appcompat-v7, design) and 26.4.0 (for support-core-ui). Android requires all support library components to use the exact same version to avoid compatibility issues.
2. Google Play Services version conflict: The new vas3g-api:2.0.0 dependency likely relies on a different version of Google Play Services than your project's current 11.4.2 version. This mismatch breaks access to internal GMS classes like com.google.android.gms.internal.zzbck.

1. Unify All Android Support Library Versions #

Update every support-related dependency to the same version (we'll use 26.4.0 since you already added support-core-ui at this version):

2. Force a Unified Google Play Services Version #

Add a resolution strategy to your android block to ensure all dependencies use the same GMS version (your project's 11.4.2, or adjust if vas3g-api requires a higher compatible version).

3. Optional: Use Specific GMS Modules Instead of the Full Package #

Instead of including the entire play-services library (which is bloated and prone to conflicts), only add the specific GMS modules your project actually needs (e.g., play-services-maps for maps, play-services-gcm for push notifications). This reduces APK size and conflict risks.

Here's how your updated build file should look:

apply plugin: 'com.android.application'

apply plugin: 'com.google.gms.google-services'

After updating the build file, run ./gradlew clean build (or use the "Clean Project" option in Android Studio) to clear cached dependencies and recompile your project. This ensures all new versions are properly synced.
