StrictMode Policy in api 8 Android

Question

I am displaying Image in Android App from Hosted Server. So, I need to set StrictMode Policy.

But as I have checked, It requires Api 9 and I want to make it supportable in Api 8 also. So how can I solve this issue ? I am already using this in AsyncTask.

My Code :

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

If I am not using StrictMode then getting Error.

Answer 1

To solve the NetworkOnMainThreadException you're seeing, read the HTTP response input stream in your doInBackground() and not in onPostExecute().

Answer 2

StrictMode is available from 2.3 only, So you can't use it in 2.2.

There is tow possible ways I can give you.

1. Go with 2.3 [or]
2. Use AsyncTask in android.

I go with AsyncTsk

I hope this will help you.
