How to code an Android app like CPU-Z in Android Studio | Detailed Guide with Code
To create an Android app similar to CPU-Z in Android Studio, you will need to use the Android SDK and programming language such as Java or Kotlin. Here is a step-by-step guide for creating a basic app that displays hardware and system information:
Install the Android Studio development environment and set up an emulator or connect a physical Android device to your computer.
Create a new Android project in Android Studio.
Design the layout of your app. This will involve creating the necessary XML files to define the user interface of your app, including any buttons, text fields, or other UI elements you want to include. For this example, we will create a simple layout with a few TextView elements to display the information.
In your app's main activity, use the Android SDK to access the phone's hardware and system information. Add the following code to your activity:
// Get the device's model numberString model = Build.MODEL;// Get the device's manufacturerString manufacturer = Build.MANUFACTURER;// Get the device's Android versionString version = Build.VERSION.RELEASE;// Get the device's CPU architectureString cpuArch = System.getProperty("os.arch");// Get the device's CPU cores and frequencyHardwarePropertiesManager hwManager = (HardwarePropertiesManager) getSystemService(HARDWARE_PROPERTIES_SERVICE);HardwareProperties hwProperties = hwManager.getHardwareProperties(HardwarePropertiesManager.DEVICE_CPU_PROPERTIES);int numCores = hwProperties.getNumCores();float[] freqRange = hwProperties.getCpuMaxFreqKHz();float maxFreq = freqRange[HardwareProperties.INDEX_MAX];// Get the device's total and available memoryActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);ActivityManager.MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();am.getMemoryInfo(memoryInfo);long totalMemory = memoryInfo.totalMem;long availableMemory = memoryInfo.availMem;In your layout XML file, add the TextView elements to display the information. Set the text attribute of each TextView to the corresponding variable from step 4.
In your app's manifest file, add the HARDWARE_PROPERTIES_SERVICE and ACTIVITY_SERVICE permissions to allow the app to access the device's hardware and memory information.
Run your app on the emulator or physical device to see the hardware and system information displayed in the app.
Here is an example of how the final layout XML file might look:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/text_model" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Model: " /> <TextView android:id="@+id/text_manufacturer" android:layout_widthReach me if you want any help! :)
