How to Pass POJO class in Work manager in android?

Question

How can we pass Serializable object in work manager by setData method of work manager? Is there any way to process with Work manager by passing

Answer 1

Today, I also faced this issue. So I found the way to pass an object.

My Requirement is pass Bitmap object. (You can pass as per your requirement)

Add dependency in your Gradle file

Gradle:

dependencies {
  implementation 'com.google.code.gson:gson:2.8.5'
}

Use the below method for serializing and de-serializing the object

 // Serialize a single object.
    public static String serializeToJson(Bitmap bmp) {
        Gson gson = new Gson();
        return gson.toJson(bmp);
    }

    // Deserialize to single object.
    public static Bitmap deserializeFromJson(String jsonString) {
        Gson gson = new Gson();
        return gson.fromJson(jsonString, Bitmap.class);
    }

Serialize object.

 String bitmapString = Helper.serializeToJson(bmp);

Pass to the data object.

 Data.Builder builder = new Data.Builder();
 builder.putString("bmp, bitmapString);
 Data data = builder.build();
        OneTimeWorkRequest simpleRequest = new OneTimeWorkRequest.Builder(ExampleWorker.class)
                .setInputData(data)
                .build();
        WorkManager.getInstance().enqueue(simpleRequest);

Handle your value in Worker class.

Data data = getInputData();
String bitmapString = data.getString(NOTIFICATION_BITMAP);
Bitmap bitmap = Helper.deserializeFromJson(bitmapString);

Now your bitmap object is ready in Worker class.

Cheers !
