How to enable/disable gps and mobile data in andro

Question

I want my application to be able to enable/disable gps and mobile data programmatically as there are many apps like tasker, profile flow, lookout extra which can do this so I searched for it but not found any useful example I found the following code but they didn't work.

private void setMobileDataEnabled(Context context, boolean enabled) {
 final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
 final Class conmanClass = Class.forName(conman.getClass().getName());
 final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
 iConnectivityManagerField.setAccessible(true);
 final Object iConnectivityManager = iConnectivityManagerField.get(conman);
 final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
 final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
 setMobileDataEnabledMethod.setAccessible(true);

 setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
} 

private void turnGPSOn(){
 String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

 if(!provider.contains("gps")){ //if gps is disabled
    final Intent poke = new Intent();
    poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
    poke.setData(Uri.parse("3")); 
    sendBroadcast(poke);
 }
}

private void turnGPSOff(){
 String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

 if(provider.contains("gps")){ //if gps is enabled
    final Intent poke = new Intent();
    poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
    poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
    poke.setData(Uri.parse("3")); 
    sendBroadcast(poke);
 }
}

Try this for turning on gps

public void turnGPSOn()
{
     Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
     intent.putExtra("enabled", true);
     this.ctx.sendBroadcast(intent);

    String provider = Settings.Secure.getString(ctx.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
    if(!provider.contains("gps")){ //if gps is disabled
        final Intent poke = new Intent();
        poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
        poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
        poke.setData(Uri.parse("3")); 
        this.ctx.sendBroadcast(poke);


    }
}

for turning off gps,

public void turnGPSOff()
{
    String provider = Settings.Secure.getString(ctx.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
    if(provider.contains("gps")){ //if gps is enabled
        final Intent poke = new Intent();
        poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
        poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
        poke.setData(Uri.parse("3")); 
        this.ctx.sendBroadcast(poke);
    }
}

For mobile data, did you added the permission in manifest? If not try adding and check it.

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

Let me know if everything worked.

Answer 2

I want my application to be able to enable/disable gps

Fortunately, this is not possible, for obvious privacy reasons. While there were some hacks, like the one in your question, that used to work, those security flaws have since been fixed.

as there are many apps like tasker, profile flow, lookout extra which can do this

You are welcome to supply evidence that any of those apps can do this on modern versions of Android.
