Retryable async task for Android. It retries a executed job in case of failure.
// Params, Progress and Result could be anything, same as a regular AsyncTask
new RetryableAsyncTask<Params, Progress, Result>(myActivity) {
@Override
protected void onPreExecute() {
// write some code here
}
@Override
protected Result doInBackground(Params... params) {
// execute some expensive task here with your params
// eg: MyExpensiveTask with method called 'get'
return MyExpensiveTask.get(params);
}
@Override
protected void onPostExecute(Result result) {
// write some code here with your result
}
}.execute(myParams);By the default, onError method shows a dialog "Cancel" and "Retry" button options.
However, you might wanna do something else when something goes wrong. To do so,
override onError with your own error handling.
// Params, Progress and Result could be anything, same as a regular AsyncTask
new RetryableAsyncTask<Params, Progress, Result>(myActivity) {
// ...
@Override
protected void onError(Throwable error, final Params... params) {
// write your own error handling
}
}.execute(myParams);repositories {
// ...

If there are issues open, I recommend you follow those steps:
- Create a branch retryableasynctask#{issue_number}; eg: retryableasynctask#42
- Please, remember to write unit tests.
- Send a pull request!
I strongly recommend to use Android Studio for a smooth integration, but follow the command below if you wanna run all unit tests by your own.
