Application with Internet for the main and without for the rest

Question

I have an app in which starting page needs internet,

Rest want to work without internet (ie, only one activity need the internet permission).

But when I turn off the Internet, the app shows a message like turn internet connection on and then only I can proceed to further (Here i want to work with out internet). Is there any solution for that?

Another activity, which does not require internet:

public class showDialog extends ActionBarActivity
{
CheckBox b1,b2,b3,b4;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dialog_sub);

    b1=(CheckBox)findViewById(R.id.checkBox1);
    b2=(CheckBox)findViewById(R.id.checkBox2);
    b3=(CheckBox)findViewById(R.id.checkBox3);
    b4=(CheckBox)findViewById(R.id.checkBox4);

    final List<String> subs=new ArrayList<String>();

    ImageButton bn=(ImageButton)findViewById(R.id.imageButton1);
    bn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            if(b1.isChecked())
                subs.add(b1.getText().toString());
            if(b2.isChecked())
                subs.add(b2.getText().toString());
            if(b3.isChecked())
                subs.add(b3.getText().toString());
            if(b4.isChecked())
                subs.add(b4.getText().toString());
            System.out.print("subjects "+subs);

            Intent intent = new     Intent(showDialog.this,testClass.class);
            intent.putStringArrayListExtra("subject",   (ArrayList<String>) subs);
            startActivity(intent);
        }
    });
}

}

Answer 1

in your AndroidManifest.xml put :

 <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

and inonCreate method of each activity you don't want to use the internet_connection in:

WifiManager wifiManager = (WifiManager)this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(false);

Answer 2

It seems you didn't write this Android application by yourself (or else you would understand what the message means). This message that "asks for internet connection" is something that is done through your app and not by the Android framework. Please understand your application first, then ask questions about it.

Hint: Search for the String inside your app (by search functionality of your IDE) that is shown in your "asks for internet connection" message and look up why it is displayed. You will see, that you can disable it.

Answer 3

You can only set permission for the complete app, not on single activity.

Why is it so important that the user doesn't have an internet connection in the rest of the app? When you don't code anything that connects to the internet in those "internet-free" activities, then you won't use up the (possible) date
