解決
Add the below function after setContentView() in onCreate().
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy);
}
This worked for me. Hope it will work for you.
他のヒント
By the way
It's better to use AsyncTask for background tasks.
Along with the strict mode policy set your mobile date and time correctly it will work fine
