Features

• Performance — Battery level/status, total RAM, device info
• Apps — Installed apps list, filter by name, show/hide system apps
• Cache — Scan and clear this app's own cache
• About — App info, links to G23 projects

No root required. Android restricts killing other apps or clearing their cache — this app works within those limits.

How to get the APK (step by step, no Android Studio needed)

Step 1 — Create a GitHub account

1. Go to github.com
2. Click Sign up and create a free account
3. Verify your email

Step 2 — Create a new repository

1. Click the + button (top right) → New repository
2. Name it: TaskManagerPlusAndroid
3. Set it to Public
4. Do NOT check "Add a README" — leave it empty
5. Click Create repository

Step 3 — Upload the files

1. On the empty repo page, click uploading an existing file
2. Upload ALL the files you downloaded, keeping the folder structure:

   App.js
   app.json
   babel.config.js
   eas.json
   package.json
   .gitignore
   src/
     theme.js
     screens/
       PerformanceScreen.js
       AppsScreen.js
       CacheScreen.js
       AboutScreen.js
   .github/
     workflows/
       build.yml
   

   Important: GitHub's web uploader doesn't create folders automatically. You need to type the path manually when uploading, e.g. type src/theme.js in the filename field. Or use the method below.

Step 3 (easier alternative) — Use GitHub Desktop

1. Download GitHub Desktop
2. Sign in with your GitHub account
3. Clone your new empty repo to your PC
4. Copy all the project files into the cloned folder (keeping folder structure)
5. In GitHub Desktop: write a commit message → click Commit → click Push

Step 4 — Watch the build

1. Go to your repo on github.com
2. Click the Actions tab
3. You'll see a workflow called "Build Android APK" running
4. Wait 5–10 minutes for it to finish (green checkmark = success)

Step 5 — Download the APK

1. Click on the completed workflow run
2. Scroll down to Artifacts
3. Click TaskManagerPlus-APK to download a .zip
4. Unzip it — inside is app-release.apk

Step 6 — Install on your phone

1. Send the APK to your phone (WhatsApp, Google Drive, USB cable, etc.)
2. Open it on your phone
3. Android will ask to "Allow from this source" — tap Allow
4. Install and open TaskManager+
