Question

I wanted to learn twitter connect example. For that i just downloaded a sample app from here. I just tried to run that app. When I run this app on Android 2.3.3, it is working fine but when I run it on android 4.1.2, it’s giving an error NetworkOnMainThreadException. In that code, the author has used AsynTask background thread to perform network operations but still this error exists. Now I am confused, where is the error coming from. Please help.

Answer 1

There are two Solution of this Problem.

1) Don’t write network call in Main UIThread, Use Async Task for that.

2) Write below code into your MainActivity file after setContentView(R.layout.activity_main);

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

And below import statement into your java file.

import android.os.StrictMode;
