In this tutorial we will explore examples of how to obtain device info from your android phone.
Example 1: Get Android Device Info – Java
This is a java example on how to get the android device info programmatically. Follow the following steps to recreate the project.
Step 1: Dependencies
No special dependency is needed.
Step 2: Permissions
No special permissions are needed.
Step 3: Design Layout
We have and need only one layout, the layout for our MainActivity.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/view_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
android:orientation="vertical"
tools:context="com.elyeproj.deviceinfo.MainActivity">
</LinearLayout>Step 4: Write Code
Here is the full code
MainActivity.java

public class MainActivity extends AppCompatActivity {
private float deviceDensity = 0;
private ViewGroup containerView = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
containerView = (ViewGroup)findViewById(R.id.view_container);
calculateDensity();
calculateDeviceInfo();
calculateStatusBar();
}
private void calculateDensity() {
deviceDensity = getResources().getDisplayMetrics().density;
String densityStr = "Undefined";

else if (deviceDensity == 2.0) densityStr = "XHDPI";
else if (deviceDensity == 3.0) densityStr = "XXHDPI";
else if (deviceDensity == 4.0) densityStr = "XXXHDPI";
addTextView("Density Value: " + deviceDensity + "(" + densityStr + ")");
}
private void calculateDeviceInfo() {
Display display = getWindowManager().getDefaultDisplay();
DisplayMetrics outMetrics = new DisplayMetrics();
display.getMetrics(outMetrics);
float dpHeight = outMetrics.heightPixels / deviceDensity;
float dpWidth = outMetrics.widthPixels / deviceDensity;
addTextView("Height Resolution(dp): " + dpHeight);
addTextView("Width Resolution(dp): " + dpWidth);
}
private void calculateStatusBar() {
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
float dpStatusBar = getResources().getDimensionPixelSize(resourceId)/deviceDensity;
addTextView("Status Bar Resolution(dp)\t: " + dpStatusBar);
}
}
private void addTextView(String text) {
TextView textView = new TextView(this);
textView.setText(text);
containerView.addView(textView);
}
}

Gradle Dependecy
dependencies {
implementation 'com.an.deviceinfo:deviceinfo:0.1.5'
}Maven Dependecy
<dependency>
<groupId>com.an.deviceinfo</groupId>
<artifactId>deviceinfo</artifactId>
<version>0.1.5</version>
<type>pom</type>
</dependency>Download

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.
Step 2: Usage
For easy use, I have split up all the device information by the following:
- Location
- Ads
- App
- Battery
- Device
- Memory
- Network
- User Installed Apps
- User Contacts
Location
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 Ads
No Google play services needed!
AdInfo adInfo = new AdInfo(this); adInfo.getAndroidAdId(new new AdInfo.AdIdCallback() { @Override public void onResponse(Ad ad) { String advertisingId = ad.getAdvertisingId(); Boolean canTrackAds = ad.isAdDoNotTrack(); } });Value Function Name Returns AdvertisingId getAdvertisingId()String Can Track ads isAdDoNotTrack()boolean App
App app = new App(this);Value Function Name Returns App Name getAppName()String Package Name getPackageName()String Activity Name getActivityName()String App Version Name getAppVersionName()String App Version Code getAppVersionCode()Integer Battery

UserContactInfo userContactInfo = new UserContactInfo(mActivity); List<UserContacts> userContacts = userContactInfo.getContacts();Value Function Name Returns Contact Name getDisplayName()String Mobile Number getMobileNumber()String Phone Type phoneType()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);
@Override
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:
permissionManager.showPermissionDialog(permission)
.withDenyDialogEnabled(true)
.withDenyDialogMsg(mActivity.getString(R.string.permission_location))
.withCallback(new PermissionManager.PermissionCallback() {
@Override
public void onPermissionGranted(String[] permissions, int[] grantResults) {
//you can handle what to do when permission is granted
}
@Override
public void onPermissionDismissed(String permission) {
/**
* user has denied the permission. We can display a custom dialog
* to user asking for permission
* */
}
@Override
public void onPositiveButtonClicked(DialogInterface dialog, int which) {
/**
* You can choose to open the
* app settings screen
* * */
PermissionUtils permissionUtils = new PermissionUtils(this);
permissionUtils.openAppSettings();
}
@Override
public void onNegativeButtonClicked(DialogInterface dialog, int which) {
/**
* The user has denied the permission!
* You need to handle this in your code
* * */
}
})
.build();
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 |

Example 3: Use appzy/DeviceInfo
Collect Android device information and output it in the form of Json
You can freely customize the type of device to be collected, the details of the displayed device information, etc.
Features
- By inheriting
BaseDeviceInfoCollectorclasses, cooperateDeviceInfoManagerto obtain any device information - By
DeviceInfoManagermanaging each device information collector (hereinafter referred to as Collector), Collectors can be added freely to collect N kinds of software and hardware device information at the same time - Collector is divided into two collection methods: automatic collection and manual collection.
- Automatic collection: Manager controls collection that occurs spontaneously
- Manual collection: Data collection process that requires user interaction
- Multiple Collectors managed by Manager do concurrent automatic collection, and manual collection can be configured to start automatically after the automatic collection action ends
- Each Collector independently manages the permissions it needs and applies it in the Manager (SDK_VERSION >= 23)
- You can choose to get the device information of all modules (Json), or you can choose to output only a single module (Json)
- Provides rich status callback interfaces
DeviceInfoCollectListener, which can monitor various statuses such as the end of collection
Currently available device information (only used as a template, it is recommended to customize it when using it):
- Android device basic information (PhoneBasicInfoCollector)
- Sim Card Information (SimInfoCollector)
- Recognize multiple Sim cards at the same time
- Board Information (BoardInfoCollector)
- Cpu Information (CpuInfoCollector)
- Battery Info (BatteryInfoCollector)
- Screen Info (ScreenInfoCollector)
- NFC information (NfcInfoCollector)
- Sensor List (SensorInfoCollector)
- Camera Info (CameraInfoCollector)
- Storage Information (RAM & SD) (StorageInfoCollector)
- Ui Information (UiInfoCollector)
- System related information (Build.prop, etc.)z
Step 1: Add dependency library
-
Step 1.Add it in your root build.gradle at the end of repositories
allprojects { repositories { ... maven { url 'https://jitpack.io' } } } -
Step 2.Add the dependency
dependencies { implementation 'com.github.guyuepeng:DeviceInfo:xxx' }
Step 2: Write Code
DeviceInfoManager.NewInstance(this)
.addCollector(new PhoneBasicInfoCollector(this, "basic")) //Andorid设备基本信息（PhoneBasicInfoCollector）
.addCollector(new SimInfoCollector(this, "sim")) //Sim卡信息（SimInfoCollector）同时识别多张Sim卡
.addCollector(new CpuInfoCollector(this, "cpu")) //Cpu信息（CpuInfoCollector）
.addCollector(new BoardInfoCollector(this, "board")) //主板信息（BoardInfoCollector）
.addCollector(new BatteryInfoCollector(this, "battery")) //电池信息（BatteryInfoCollector）
.addCollector(new StorageInfoCollector(this, "storage")) //存储信息（RAM & SD）（StorageInfoCollector）
.addCollector(new CameraInfoCollector(this, "camera", true)) //摄像头信息（CameraInfoCollector）
.addCollector(new ScreenInfoCollector(this, "screen")) //屏幕信息（ScreenInfoCollector）
.addCollector(new UiInfoCollector(this, "ui")) //Ui信息（UiInfoCollector）
.addCollector(new SensorInfoCollector(this, "sensor")) //传感器列表（SensorInfoCollector）
.addCollector(new NfcInfoCollector(this, "nfc")) //NFC信息（NfcInfoCollector）
.addCollector(new SystemInfoCollector(this, "system")) //系统相关信息（Build.prop等）
.autoStartManualCollection(true)
.bindListener(mDeviceInfoCollectListener)
.start();Default output:
{
"board": {"boardName": "MSM8939"},
"sim": [{
"dataState": "0",
"imsi": "460036820263837",
"isNetworkRoaming": "false",
