Welcome folks today in this blog post we will be seeing how to display system hardware and system cpu info inside the textview widget in java. All the full source code of the application is shown below.
Get Started
In order to get started you need to make a new android project inside the android studio and then you will see the below directory structure as shown below at the end of the project.
Editing the Main Layout
Now we need to edit the activity_main.xml file for the project where we will have the simple TextView widget in the RelativeLayout as shown below
activity_main.xml
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <TextView android:id="@+id/config_details_text_view" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="16dp" android:textSize="18sp" /> </RelativeLayout> |
And now we need to edit the MainActivity.java file and copy paste the following code
MainActivity.java

package com.example.randomimage; import android.os.Bundle; import android.widget.TextView; import androidx.appcompat.app.AppCompatActivity; public class MainActivity extends AppCompatActivity { private TextView configDetailsTextView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); configDetailsTextView = findViewById(R.id.config_details_text_view); String configDetails = PhoneConfigDetails.getConfigurationDetails(); configDetailsTextView.setText(configDetails); } } |
As you can see in the above java code we are calling the method which is defined inside the PhoneConfigDetails class so now we need to define that as shown below
PhoneConfigDetails.java

package com.example.randomimage; import android.os.Build; import android.util.Log; public class PhoneConfigDetails { private static final String TAG = "PhoneConfigDetails"; public static String getConfigurationDetails() { StringBuilder builder = new StringBuilder(); builder.append("Build Info:\n\n"); builder.append("Manufacturer: ").append(Build.MANUFACTURER).append("\n"); builder.append("Model: ").append(Build.MODEL).append("\n"); builder.append("Device: ").append(Build.DEVICE).append("\n"); builder.append("Product: ").append(Build.PRODUCT).append("\n"); builder.append("Board: ").append(Build.BOARD).append("\n"); builder.append("Bootloader: ").append(Build.BOOTLOADER).append("\n"); builder.append("CPU ABI: ").append(Build.CPU_ABI).append("\n"); builder.append("CPU ABI2: ").append(Build.CPU_ABI2).append("\n"); builder.append("Display: ").append(Build.DISPLAY).append("\n"); builder.append("Fingerprint: ").append(Build.FINGERPRINT).append("\n"); builder.append("Hardware: ").append(Build.HARDWARE).append("\n"); builder.append("Host: ").append(Build.HOST).append("\n"); builder.append("ID: ").append(Build.ID).append("\n"); builder.append("Product: ").append(Build.PRODUCT).append("\n"); builder.append("Tags: ").append(Build.TAGS).append("\n"); builder.append("Type: ").append(Build.TYPE).append("\n"); builder.append("User: ").append(Build.USER).append("\n"); builder.append("Time: ").append(Build.TIME).append("\n\n"); builder.append("System Properties:\n\n"); builder.append(getSystemProperties()); String configDetails = builder.toString(); Log.d(TAG, configDetails); return configDetails; } private static String getSystemProperties() { StringBuilder builder = new StringBuilder(); String[] properties = { "ro.product.brand", "ro.product.name", "ro.product.device", "ro.product.board", "ro.build.version.release", "ro.build.version.sdk", "ro.build.date.utc", "ro.build.date", "ro.build.type", "ro.build.user", "ro.build.host", "ro.build.tags", "ro.build.fingerprint" }; for (String property : properties) { String value = System.getProperty(property); if (value != null) { builder.append(property).append(": ").append(value).append("\n"); } } return builder.toString(); } } |
As you can see for fetching all this hardware and cpu information of the mobile phone we are using the Build class which is provided by the core android library and then we are displaying these details as shown below
