Simple, single class wrapper to get device information from an android device.

This library provides an easy way to access all the device information without having to deal with all the boilerplate stuff going on inside.

As part of the process of my learning kotlin, I migrated the library to support Kotlin as well. If you would like to view the Kotlin version of the library - please checkout branch migrate_to_kotlin

Library also provides option to ask permissions for Marshmellow devices!

Sample App

Donwload the sample app on the Google Play Store and check out all the features

How to integrate the library in your app?

Gradle Dependecy
dependencies {
        implementation ''

Maven Dependecy



You can download the aar file from the release folder in this project.
In order to import a .aar library:
1) Go to File>New>New Module
2) Select "Import .JAR/.AAR Package" and click next.
3) Enter the path to .aar file and click finish.
4) Go to File>Project Settings (Ctrl+Shift+Alt+S).
5) Under "Modules," in left menu, select "app."
6) Go to "Dependencies tab.
7) Click the green "+" in the upper right corner.
8) Select "Module Dependency"
9) Select the new module from the list.


For easy use, I have split up all the device information by the following:
1. Location
2. Ads
3. App
4. Battery
5. Device
6. Memory
7. Network
8. User Installed Apps
9. User Contacts


LocationInfo locationInfo = new LocationInfo(this);
DeviceLocation location = locationInfo.getLocation();
Value Function Name Returns
Latitude getLatitude() Double
Longitude getLongitude() Double
Address Line 1 getAddressLine1() String
City getCity() String
State getState() String
CountryCode getCountryCode() String
Postal Code getPostalCode() String

How to get Permissions for android 6+

Easy! I have provided a small, easy wrapper for getting permissions for marshmellow devices.

First, override onRequestPermissionsResult and call PermissionManager.handleResult(requestCode, permissions, grantResults);

PermissionManager permissionManager = new PermissionManager(this);
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        permissionManager.handleResult(requestCode, permissions, grantResults);

Now you can ask permission:

                    .withCallback(new PermissionManager.PermissionCallback() {
                        public void onPermissionGranted(String[] permissions, int[] grantResults) {
                            //you can handle what to do when permission is granted

                        public void onPermissionDismissed(String permission) {
                             * user has denied the permission. We can display a custom dialog 
                             * to user asking for permission
                           * */

                        public void onPositiveButtonClicked(DialogInterface dialog, int which) {
                            * You can choose to open the
                            * app settings screen
                            * * */
                              PermissionUtils permissionUtils = new PermissionUtils(this);

                        public void onNegativeButtonClicked(DialogInterface dialog, int which) {
                            * The user has denied the permission!
                            * You need to handle this in your code
                            * * */

Various options available in PermissionManager

Value Function Name Returns
To enable custom dialog when user has denied the permission withDenyDialogEnabled() boolean
To enable Rationale, explaining the need for the permission, the first time they have denied the permission withRationaleEnabled() boolean
Message to be displayed in the custom dialog withDenyDialogMsg() String
Title to be displayed in the custom dialog withDenyDialogTitle() String
Postive Button text to be displayed in the custom alert dialog withDenyDialogPosBtnText() String
Negative Button text to be displayed in the custom alert dialog withDenyDialogNegBtnText() String
Should display the negative button flag withDenyDialogNegBtn() boolean
Flag to cancel the dialog isDialogCancellable() boolean
