Answer
There are two Solution of this Problem.
1) Don't write network call in Main UI Thread, 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;
