  • Wallet & Rewarded Ad ready

Here's a comprehensive guide on how to import a ready-to-use Android Studio project from a .zip file, ensuring all activities, layouts, Firebase setup, and AdMob integration are intact.

📥 Step 1: Download and Extract the Project

  1. Download the .zip file containing the Android Studio project.

  2. Extract the .zip file to a known location on your computer. Ensure you extract it to a directory, not just view its contents.

🛠️ Step 2: Import the Project into Android Studio

Option 1: Import via Android Studio

  1. Open Android Studio.

  2. On the Welcome Screen, click on "Open an existing Android Studio project".

  3. Navigate to the directory where you extracted the project.

  4. Select the project folder (not the .zip file) and click OK.

    Note: If you're already working within a project, you can go to File > Open and select the project folder.

  5. Android Studio will index the project, download necessary dependencies, and sync the project.

Option 2: Import via File Menu

  1. Open Android Studio.

  2. Go to File > New > Import Project.

  3. Navigate to the extracted project folder and select it.

  4. Follow the prompts to complete the import process.

🔄 Step 3: Sync and Build the Project

  1. Once the project is loaded, Android Studio will prompt you to sync the project. Click on "Sync Now" in the bar that appears.

  2. After syncing, click on Build > Make Project to compile the project.

    Note: Ensure you have a stable internet connection, as Android Studio may need to download additional dependencies.

✅ Step 4: Run the Project

  1. Connect your Android device via USB or use an Android Emulator.

  2. Click on the Run button (green triangle) in Android Studio.

  3. Select your device and wait for the app to launch.

🧩 Troubleshooting Tips

  • Gradle Sync Issues: If you encounter errors during Gradle sync, try the following:

    • Invalidate Caches: Go to File > Invalidate Caches / Restart.

    • Check Gradle Version: Ensure the gradle-wrapper.properties file has a compatible Gradle version.

    • Update Dependencies: Check if any dependencies are outdated and update them accordingly.

  • Firebase Configuration: Ensure that the google-services.json file is placed in the app/ directory and is correctly configured in the Firebase Console.

  • AdMob Integration: Verify that your AdMob App ID and Ad Unit IDs are correctly set in the AndroidManifest.xml and relevant Java files.

I will provide you the full Java code and XML layouts for all the files you listed so you can copy them into your Android Studio project. This will give you a fully functional Task Earning App with Firebase integration.

✅ All Java & XML files are ready.
Next step: Put google-services.json from Firebase in your app/ folder and replace "YOUR_AD_UNIT_ID" with your actual AdMob rewarded ad ID.

Here’s exactly how to get it ready:

Step 1: Create the Project Structure

  1. Open Android Studio → New Project → Empty Activity

  2. Name it TaskEarningApp, package com.example.taskearningapp

  3. Minimum SDK: 24+

  4. Finish creating the project

Step 2: Add the Files

  1. Replace MainActivity.java, LoginActivity.java, SignupActivity.java, ResetPasswordActivity.java, TaskListActivity.java, WalletActivity.java, TaskAdapter.java, TaskModel.java with the code I provided above.

  2. Add the XML layouts (activity_main.xml, activity_login.xml, etc.) into res/layout/.

  3. Place any drawable icons in res/drawable/.

Step 3: Add Dependencies

Update app/build.gradle:

dependencies {
    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'androidx.recyclerview:recyclerview:1.3.1'
    implementation 'com.google.android.material:material:1.10.0'
    implementation 'com.google.firebase:firebase-auth:22.1.1'
    implementation 'com.google.firebase:firebase-firestore:24.6.1'
    implementation 'com.google.android.gms:play-services-ads:22.3.0'
}
apply plugin: 'com.google.gms.google-services'

Step 4: Add Firebase Configuration

  1. Go to Firebase Console

  2. Add Android App → Package Name com.example.taskearningapp

  3. Download google-services.json → put it in app/ folder

Step 5: Replace AdMob ID

In TaskListActivity.java, replace:

RewardedAd.load(this, "YOUR_AD_UNIT_ID", adRequest, new RewardedAdLoadCallback() {});

with your actual AdMob Rewarded Ad Unit ID.

Step 6: Run the Project

  • Sync Gradle → Build → Run on emulator or device

  • You’ll see the MainActivity → Login/Signup → Task List → Wallet

Step 7: Export as ZIP

  1. Close Android Studio.

  2. Right-click the project folder (TaskEarningApp) → Send to → Compressed (zipped) folder (Windows) or Compress (Mac)

  3. You now have a ready-to-import .zip project for Android Studio.
