Error message : Field require API Level 11 (current min is 9) : android .os.AsynTask#THREAD_POOL_EXECUTOR

I am using the AsyncTask to do network operation and set the minSDKVersion to 8. I am trying to execute the AsyncTask like how, it gives red line error then I need to clean the project everytime then it works.

downloadAsyncTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);

To avoid these errors What I can do for this ?

Here see the screenshot what is the use of these @SuppressLint, @TargetAPI,

enter image description here

Thanks in advance.

That method (executeOnExecutor()) and that field (THREAD_POOL_EXECUTOR) were added in API Level 11. Your minSdkVersion is 9, and so some devices that you run on will not have that method or field, and you will crash.

Either raise your minSdkVersion to 11, or only use executeOnExecutor() on new-enough devices:

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