Enable/disable data connection in android programmatically

Question

I want to enable/disable the data connection programmatically. I've used the following code:

void enableInternet(boolean yes)
{
    ConnectivityManager iMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
    Method iMthd = null;
    try {
        iMthd = ConnectivityManager.class.getDeclaredMethod("setMobileDataEnabled", boolean.class);
        } catch (Exception e) {
               } 
    iMthd.setAccessible(false);

    if(yes)
     {

                try {
                    iMthd.invoke(iMgr, true);
                    Toast.makeText(getApplicationContext(), "Data connection Enabled", Toast.LENGTH_SHORT).show();
                } catch (IllegalArgumentException e) {
                    // TODO Auto-generated catch block
                     dataButton.setChecked(false);
                     Toast.makeText(getApplicationContext(), "IllegalArgumentException", Toast.LENGTH_SHORT).show();

                } catch (IllegalAccessException e) {
                    // TODO Auto-generated catch block
                    Toast.makeText(getApplicationContext(), "IllegalAccessException", Toast.LENGTH_SHORT).show();

                    e.printStackTrace();
                } catch (InvocationTargetException e) {
                    // TODO Auto-generated catch block
                     dataButton.setChecked(false);
                     Toast.makeText(getApplicationContext(), "InvocationTargetException", Toast.LENGTH_SHORT).show();

                }

     }
    else
     {
        try {
            iMthd.invoke(iMgr, true);
            Toast.makeText(getApplicationContext(), "Data connection Disabled", Toast.LENGTH_SHORT).show();
            } catch (Exception e) {
                   dataButton.setChecked(true);
                Toast.makeText(getApplicationContext(), "Error Disabling Data connection", Toast.LENGTH_SHORT).show();
                                    }
     }
}

It's working without any errors in the emulator but, I'm getting "InvocationTargetException" when I try to run it on a real device. I'm using API level 8 to build the application.

What is the result of e.getMessage() on the InvocationTargetException? How about the enclosed exception? — Greyson

What device are you running this on and what version of Android OS is installed on that device. — David Wasser

I'm running it on a Samsung Galaxy S and the Android OS is 2.2 — JiTHiN

This code sample should work for android phones running gingerbread and higher:

private void setMobileDataEnabled(Context context, boolean enabled) throws ClassNotFoundException, NoSuchFieldException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {
    final ConnectivityManager conman = (ConnectivityManager)  context.getSystemService(Context.CONNECTIVITY_SERVICE);
    final Class conmanClass = Class.forName(conman.getClass().getName());
    final Field connectivityManagerField = conmanClass.getDeclaredField("mService");
    connectivityManagerField.setAccessible(true);
    final Object connectivityManager = connectivityManagerField.get(conman);
    final Class connectivityManagerClass =  Class.forName(connectivityManager.getClass().getName());
    final Method setMobileDataEnabledMethod = connectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
    setMobileDataEnabledMethod.setAccessible(true);

    setMobileDataEnabledMethod.invoke(connectivityManager, enabled);
}

Dont forget to add this line to your manifest file

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

Thanks for reply but, I have already add permission and I am using Android 2.2

For android versions less than 2.3 we can use the java reflection method to enable/disable data connection. Refer stackoverflow.com/questions/11662978/….

@riHaN JiTHiN your program works fine for 2.3 and above, But it needs a small change in 'else' statement:

else
     {
        try {
            iMthd.invoke(iMgr, true);

the 'true' should be changed to 'false'

iMthd.invoke(iMgr, false);
