Error StrictMode$AndroidBlockGuardPolicy.onNetwork
This question already has an answer here:
you have to insert 2 lines "StrictMode" on MainActivity Class, example's below:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
try {
// JSON here
} catch (JSONException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
setContentView(R.layout.activity_main);
Intent intent=new Intent(this,HomeActivity.class);
startActivity(intent);
}
}

Better to use AsyncTask as mentioned here, an Alternative for just getting rid of the Exception is use :
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
or this :
Thread thread = new Thread(new Runnable(){
@Override
public void run() {
try {
//Your code goes here
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
}
});
thread.start();
in your Activity where Exception occurs.
在创建方法后只需添加两行
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
