Dynamic Utils

A collection of static methods and packages to perform dynamic operations on Android 2.3 (API 9) and above.

Since v0.4.0, it uses 26.x.x support libraries so, minimum SDK will be Android 4.0 (API 14).
Since v2.0.0, it uses AndroidX so, first migrate your project to AndroidX.
Since v3.3.0, added Concurrent package to replace the deprecated AsyncTask API.
Since v4.1.0, it is dependent on Java 8 due to the dependency on AndroidX Core.
Since v4.3.0, it supports some helper methods to capture results via Barquode app.
Since v4.5.1, it is targeting Java 17 to provide maximum compatibility.



It can be installed by adding the following dependency to your build.gradle file:

dependencies {
    // For AndroidX enabled projects.
    implementation 'com.pranavpandey.android:dynamic-utils:4.5.1'

    // For legacy projects.
    implementation 'com.pranavpandey.android:dynamic-utils:1.3.0'


It is divided into different classes according to their category for easy understanding and usage. This library is fully commented so I am highlighting some of the functions below, keep exploring for more hidden features.

For a complete reference, please read the documentation.


A set of classes to perform quick or long running asynchronous operations. It is built according to the familiar AsyncTask API to provide a lightweight replacement and easy migrations as that was deprecated in Android 11 (API 30).

It uses java.util.concurrent package in the background to do most of the operations. Please check the task package to know more about the basic implementation.

 * Extend the base DynamicTask class and implement the required methods.
public class Task<Params, Progress, Result> extends DynamicTask<Params, Progress, Result> {

     * This method will be called before doing the background work.
    protected void onPreExecute() {
        // Initialize on the main thread like showing the progress dialog.

     * This method will be called for doing the background work.
     * @param params The optional parameters required for the work.
     * @return The optional result object.
    protected abstract @Nullable Result doInBackground(@Nullable Params params) {
        // Perform the task in the background and return the result.

     * This method will be called on publishing the progress.
     * @param progress The progress returned by the work.
    protected void onProgressUpdate(@Nullable DynamicResult<Progress> progress) {
        // Optional method to publish progress on the main thread.

     * This method will be called after completing the work.
     * @param result The result returned by the work.
    protected void onPostExecute(@Nullable DynamicResult<Result> result) {
        // Finalize on the main thread and do operations with the result.

Execute the above task by configuring your own ExecutorService or by using the DynamicExecutor.

You can also call DynamicTask.execute() which uses the DynamicExecutor with a ThreadPoolExecutor in the background. It is an experimental feature and may change in the future.

It has various helper methods in intent utils to capture results via the Barquode app available for Android.

 * @param context The context to get the package manager.
 * @return {@code true} if the device has at least one activity to capture the matrix result.
public static boolean isMatrixCaptureResult(@Nullable Context context);

 * Returns the intent to capture the matrix result.
 * @param context The context to get the intent.
 * @return The intent to capture the matrix result.
public static @NonNull Intent getMatrixCaptureResultIntent(@Nullable Context context);


Barquode app returns the result in the form of intent extras.
