Membuat Aplikasi Battery Info Android, Informasi Status Baterai Handphone ini penulis dapatkan dari sebuah buku. Aplikasi ini cukup berguna untuk memberi informasi bahwa baterai dalam kondisi charging, penuh, hampir habis, atau dalam keadaan masih bagus, atau sudah rusak, dan sebagainya.Untuk membuat aplikasi ini butuh permission BATTERY_STATS yang menunjukkan bahwa aplikasi boleh melihat status baterai milik perangkat Android.
Caranya buat project baru, kemudian buat tampilan sederhana dengan 5 buah TextView pada file layout activity_main.xml seperti ini :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<TextView
android:id="@+id/tvBatteryLevel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Battery Level" />
<TextView
android:id="@+id/tvBatteryVoltage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Battery Voltage" />
<TextView
android:id="@+id/tvBatteryTemperature"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Battery Temperature" />
<TextView
android:id="@+id/tvBatteryTechnology"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Battery Technology" />
<TextView
android:id="@+id/tvBatteryStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Battery Status" />
<TextView
android:id="@+id/tvBatteryHealth"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Battery Health" />
</LinearLayout>
Kemudian pada kode program utama di MainActivity.java ketikkan seperti ini :
package com.amijaya.android_battery_info;
import android.os.BatteryManager;
import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.view.Menu;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
registerReceiver(new BroadcastReceiver() {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
if (arg1.getAction().equals(Intent.ACTION_BATTERY_CHANGED)){
TextView tvBatteryLevel = (TextView)findViewById(R.id.tvBatteryLevel);
TextView tvBatteryVoltage = (TextView)findViewById(R.id.tvBatteryVoltage);
TextView tvBatteryTemperature = (TextView)findViewById(R.id.tvBatteryTemperature);
TextView tvBatteryTechnology = (TextView)findViewById(R.id.tvBatteryTechnology);
TextView tvBatteryStatus = (TextView)findViewById(R.id.tvBatteryStatus);
TextView tvBatteryHealth = (TextView)findViewById(R.id.tvBatteryHealth);
tvBatteryLevel.setText("Level: "
+ String.valueOf(arg1.getIntExtra("level", 0)) + "%");
tvBatteryVoltage.setText("Voltage: "
+ String.valueOf((float)arg1.getIntExtra("voltage", 0)/1000) + "V");
tvBatteryTemperature.setText("Temperature: "
+ String.valueOf((float)arg1.getIntExtra("temperature", 0)/10) + "c");
tvBatteryTechnology.setText("Technology: " + arg1.getStringExtra("technology"));
int status = arg1.getIntExtra("status", BatteryManager.BATTERY_STATUS_UNKNOWN);
String strStatus;
if (status == BatteryManager.BATTERY_STATUS_CHARGING){
strStatus = "Charging";
} else if (status == BatteryManager.BATTERY_STATUS_DISCHARGING){
strStatus = "Dis-charging";
} else if (status == BatteryManager.BATTERY_STATUS_NOT_CHARGING){
strStatus = "Not charging";
} else if (status == BatteryManager.BATTERY_STATUS_FULL){
strStatus = "Full";
} else {
strStatus = "Unknown";
}
tvBatteryStatus.setText("Status: " + strStatus);
int health = arg1.getIntExtra("health", BatteryManager.BATTERY_HEALTH_UNKNOWN);
String strHealth;
if (health == BatteryManager.BATTERY_HEALTH_GOOD){
strHealth = "Good";
} else if (health == BatteryManager.BATTERY_HEALTH_OVERHEAT){
strHealth = "Over Heat";
} else if (health == BatteryManager.BATTERY_HEALTH_DEAD){
strHealth = "Dead";
} else if (health == BatteryManager.BATTERY_HEALTH_OVER_VOLTAGE){
strHealth = "Over Voltage";
} else if (health == BatteryManager.BATTERY_HEALTH_UNSPECIFIED_FAILURE){
strHealth = "Unspecified Failure";
} else{
strHealth = "Unknown";
}
tvBatteryHealth.setText("Health: " + strHealth);
}
}
}, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
Terakhir jangan lupa memberi permission BATTERY_STATS
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.amijaya.android_battery_info"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="16" />
<uses-permission android:name="android.permission.BATTERY_STATS"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.amijaya.android_battery_info.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Jika dijalankan hasilnya :
Project androidnya bisa didownload. Jika kesulitan silakan cek caranya.
