Batch push of data to the server

The library is still not available through Maven or Gradle. You need to add android-data-agent project as a dependency to your project.

The library stores the data based on group. Each group has an id, a data handler, a sync policy, a url, sync priority and few other configurations.

This defines the uniqueness of the group. This is used for setting the data handler and then pushing the data to the library

Sync priority defines the frequency at which the group will be poked for getting a batch of data from the group for syncing.

Sync policy defines the instance when the data would be elegible for syncing and the batch size within each group which has to be used in a single sync call. Sync policy is a member of data handler

GroupDataHandler knows about the kind of data which is being sent for a group. It knows about the data and hence handles the task of batch creation from the data group. It maintains the data group, the maximum size of which is defined by it's property maxBatchSize. You can change this to suite your needs. When the data overflows this value, the first-in data is purged in the quantum defined by the property elementCountToDeleteOnBatchFull.

String performanceEvent = @"perf";

An object of a child class of GroupDataHandler has to be provided for each group. This also asks for the URL to which the data of the group has to be synced

BatchNetworking.getDefaultInstance().initialize(getApplicationContext());
try {
	JSONDataHandler jdh = new JSONDataHandler(PERFORMANCE_EVENTS, BASE_URL_STRING);
	BatchNetworking.getDefaultInstance().setGroupDataHandler(jdh);
} catch (Exception e) {
	e.printStackTrace();
}

JSONDataHandler uses DefaultSyncPolicy for syncing. You can set your own sync policy. You can also set the priority of the group in the data policy. You can set the User-Agent by using the following method:

public void setUserAgent(String userAgent)

BatchNetworking.getDefaultInstance().pushDataForGroupId(element, PERFORMANCE_EVENTS);

Since you have used JSONDataHandler the element mentioned in the above method has to be of the type or the child type of com.google.mygson.JsonElement

You can implement GroupDataHandler and implement DataTypeSyncPolicy for custom handling.
