Implement in Sketchware

Blocks & Component JSON

Import these JSON files directly in Sketchware/Sketchware Pro to get pre-made blocks and component setup.

Note: Update these URLs to your actual file locations if different.

This guide will help you integrate and use PG_DevCallService for calls inside Sketchware or Sketchware Pro. Follow the steps below for a smooth setup and reliable implementation.

• Latest version of Sketchware or Sketchware Pro recommended.
• Working internet connection (required for API calls).
• You must have an active API key from your dashboard.
• Copy-paste code blocks carefully, and do not share your API key publicly.

Required Android permissions (AndroidManifest.xml)

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_ROUTING" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.REGISTER_CALL_PROVIDER" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MEDIA_PROJECTION" />
<uses-permission android:name="android.permission.CAPTURE_VIDEO_OUTPUT" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_MICROPHONE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE_CAMERA" />

Tip: Request runtime permissions for CAMERA and RECORD_AUDIO before starting a call. For Android 10+ storage use, prefer scoped storage; for Android 13+, ensure foreground service types are declared as above.

1. On your Sketchware/Sketchware Pro app, go to your project.
2. Open the Library Manager and click “Import Library”.
3. Paste/add the dependency code:
   // <Add library import instructions here>
implementation 'com.pgdev:callservice:1.0.0'
4. Sync/build your project.

// Initialize the library (place in Set ID button click event)
String customId = "your-customID";
String apiKey = "your-apiKey";
call.init(customId, apiKey);

// Start a call to a user ID
call.startCall("receiver-id");

Replace receiver-id with the actual target user ID.
