Snippet demonstrating how to ensure AsyncTasks are always executed in parallel (the default pre-HC behavior)

AsyncTaskUtils.java

import android.annotation.TargetApi;
import android.os.AsyncTask;
import android.os.Build;

public class AsyncTaskUtils {

	@TargetApi(Build.VERSION_CODES.HONEYCOMB)
	public static <P> void executeAsyncTaskInParallel(
			AsyncTask<P, ?, ?> asyncTask, P... params) {
		if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
			asyncTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
		} else {
			asyncTask.execute(params);
		}
	}
}

Usage

//Instead of myAsyncTaskInstance.execute(params), use the following:
AsyncTaskUtils.executeAsyncTaskInParallel(myAsyncTaskInstance, params);
