📖 About This Photo Editor Android Source Code

Photo Editor is a complete, ready-to-publish photo-editing Android source code written in Java using Android Studio. The app delivers a full editor experience - brush drawing with colour, opacity and brush-size pickers, text on photo with 19 bundled custom .ttf / .otf fonts, a pixel-perfect eraser, over 20 photo filters (B&W, Sepia, Vignette, Brightness, Contrast, Saturate, Sharpen, Grain, Posterize, Tint, Fish-Eye, Lomish, Cross-Process and more), a wide emoji picker, 70+ draggable stickers that can be pinch-scaled and rotated, plus full undo / redo history. Photos are imported either from the Camera or from the modern Android 13+ Photo Picker (no storage permission required on most devices). Saved edits go to app-scoped storage AND are published to the system MediaStore so they appear instantly in the device's gallery app under Pictures/PhotoEditor/. A built-in "My Creation" swipeable gallery lets the user browse every saved edit and share it via FileProvider to WhatsApp, Instagram, Drive or any compatible app. With AdMob banner + interstitial already integrated and edge-to-edge UI for Android 15, this is one of the fastest complete Android photo apps to rebrand and upload to Google Play.

What end-users get:

• 🖼 A satisfying full photo-editing experience that works fully offline.
• 🖌 Brush, text, eraser, filter, emoji and sticker tools - all the basics they expect.
• 💾 One-tap Save that puts the edit into the system gallery instantly.
• 📤 One-tap Share from the My Creation gallery to any social app.

✨ Key Features

🕹️ How the App Works for the End User

1. Unzip & open the project

1. Unzip the source archive you downloaded from Codster.
2. Open Android Studio → File → Open… and select the project root folder (photo-editor-android/).
3. Wait for the first Gradle Sync to finish — it downloads AGP, AndroidX, Glide, Google Mobile Ads, sdp-android and ColorPicker (needs an internet connection, takes 2–5 minutes).
4. If Gradle complains about the JDK, set it from Settings → Build → Gradle → Gradle JDK to JDK 17 or higher.

2. Run the app on a device / emulator

1. Plug in a real Android device (API 24+) with USB debugging enabled, OR start an emulator with a Google Play system image (required for the Android 13+ Photo Picker).
2. Press ▶ Run in Android Studio.
3. The Splash screen appears → tap Start Photo Editor → pick any photo from the system Photo Picker → start editing.

3. Change the package name & application ID (REQUIRED before Play upload)

1. Switch the Project tool window to the Project view.
2. Right-click the package com.codstereditphoto.photoeditor → Refactor → Rename → Rename package.
3. Pick your own unique package, e.g. com.yourbrand.photoeditor. Apply the rename to all three levels.
4. Open app/build.gradle and update BOTH lines (already marked with // RESKIN:):

   namespace 'com.yourbrand.photoeditor'
   applicationId "com.yourbrand.photoeditor"
   

5. Build → Clean Project then Sync Gradle.

4. Change the app name & brand colors

1. Open app/src/main/res/values/strings.xml and edit <string name="app_name">My Photo Editor</string> (drives the launcher label and splash header).
2. Open app/src/main/res/values/colors.xml and change colorPrimary, colorPrimaryDark and colorAccent to your brand palette.

5. Replace the launcher icon & splash screen

1. Right-click app/src/main/res → New → Image Asset.
2. Choose Launcher Icons (Adaptive and Legacy), drop in your 1024×1024 PNG, click Next → Finish (overwrites every mipmap-* folder).
3. To rebrand the splash screen, edit the background / logo inside app/src/main/res/layout/splash_activity.xml.

6. (Optional) Replace stickers, filters and fonts

• Stickers: drop new PNGs (with transparency, 512×512 or 1024×1024) into app/src/main/assets/stickers/ — auto-discovered at runtime, no code change needed.
• Filter thumbnails: overwrite the PNGs in app/src/main/assets/filters/.
• Fonts: drop .ttf / .otf files into app/src/main/assets/fonts/ — they appear automatically in the Text dialog font picker.

7. Set your own AdMob IDs (BEFORE publishing)

1. Sign in to AdMob Console, create a new Android app using your new applicationId.
2. Create one Banner ad unit and one Interstitial ad unit.
3. Open app/src/main/res/values/strings.xml and replace these three values:

   <string name="admob_app_id">ca-app-pub-XXXXXXXXXXXXXXXX~XXXXXXXXXX</string>
   <string name="admob_banner">ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX</string>
   <string name="admob_fullscreen">ca-app-pub-XXXXXXXXXXXXXXXX/XXXXXXXXXX</string>
   

4. Warning: during testing, add your device as a Test Device in the AdMob console. Clicking your own live ads will get your account banned.

8. (Optional) Disable ads entirely

1. In SplashActivity.java, PhotoEditorMainActivity.java and MyCreationActivity.java comment out the calls to addBannnerAdsAdmob() and addFullscreenAdsAdmob() inside onCreate().
2. Remove the <LinearLayout android:id="@+id/linAdsContainer" …/> blocks from the matching layouts.
3. Remove the three AdMob <meta-data> tags from AndroidManifest.xml.
4. Remove implementation libs.play.services.ads from app/build.gradle.

9. Generate a signed APK / AAB

1. Generate a keystore (one-time):

   keytool -genkey -v -keystore my-release-key.jks 
           -keyalg RSA -keysize 2048 -validity 10000 -alias my-app
   

   Store the .jks file and password somewhere safe — you need them for every future Play upload of the same app.
2. In Android Studio → Build → Generate Signed Bundle / APK… → choose Android App Bundle (recommended) → pick your keystore → choose release → Finish.
3. Or run from the command line:

   ./gradlew :app:assembleRelease   # APK
   ./gradlew :app:bundleRelease     # AAB for Play Store
   

10. Publish on Google Play

1. Create / open your Google Play Console account (one-time $25 fee).
2. Create app → Internal testing → upload your signed AAB.
3. Fill in the Store listing: title, short & full description, screenshots, feature graphic 1024×500, hi-res icon 512×512, privacy policy URL, content rating, target audience.
4. Promote the release to Production. Photo / utility apps usually pass Play review within 1 day.

11. Troubleshooting

• Gradle sync fails (Unsupported class file major version XX) — set Gradle JDK to 17+ from Settings → Build → Gradle → Gradle JDK.
• Manifest merger failed after package rename — Build → Clean Project, then re-sync. Confirm the folder structure under java/ matches your new namespace.
• Photo Picker shows nothing on an old emulator — use a Google Play system image, or test on a real device (Android 11+).
• Banner ad never shows — confirm internet, confirm admob_app_id in strings.xml matches the AdMob console, then wait 5–10 minutes for the first impression.
• Custom font missing in Text dialog — file extension must be .ttf or .otf, placed directly inside assets/fonts/ (no sub-folders).
• Sticker missing from picker — filename must match sticker-(NN).png inside assets/stickers/.
