Building the App

Prerequisites

• Android Studio (Arctic Fox or later)
• Android SDK (API level 21 or higher)
• JDK 8 or later

Steps

1. Open Android Studio
2. Select "Open an Existing Project"
3. Navigate to the PhotoSaver folder and open it
4. Wait for Gradle to sync
5. Connect your Android device or start an emulator
6. Click the "Run" button (green triangle) or press Shift+F10

Customization

You can easily modify the code to suit your needs:

Change the filename format

In MainActivity.java, find this line:

String filename = "photo_" + System.currentTimeMillis() + ".jpg";

You can change it to:

// Use date format
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US);
String filename = "IMG_" + sdf.format(new Date()) + ".jpg";

Set a default directory

If you want to skip the directory picker and always save to a specific folder, you can modify the app to remember the last selected directory using SharedPreferences.

Add file naming dialog

You could add a dialog to let users type a custom filename before saving.

Permissions

The app requires the following permissions:

• READ_EXTERNAL_STORAGE - To read the shared photo
• WRITE_EXTERNAL_STORAGE - Only for Android 9 and below

For Android 10+, the app uses Scoped Storage and doesn't need storage permissions.

Minimum Requirements

• Android 5.0 (API level 21) or higher
• Approximately 5MB of storage space

Troubleshooting

App doesn't appear in share menu:

• Make sure the app is installed correctly
• Try restarting your device

Can't save to certain folders:

• Some system folders may be protected
• Try selecting a different folder like Pictures or Downloads

File saves but can't find it:

• Check the folder you selected in the directory picker
• The filename format is: photo_[timestamp].jpg
