android 优化耗电量

作为app开发者，或许很少有人会注意app对电量的损耗，但是用户对电量可是很敏感的，app做好电量损耗的优化会为自己的app加分不少。

如果是一个好的负责任的开发者，就应该限制app对电量的影响，当没有网络连接的时候，禁用后台服务更新，当电池电量低的时候减少更新的频率，确保自己的app对电池的影响降到最低。当电池充电或者电量比较饱和时，可以最大限度的发挥app的刷新率

1	<receiver android:name=".PowerConnectReceiver">

2	<intent-filter>

3	<action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>

4	<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED"/>

5	</intent-filter>

6	</receiver>

01	public class PowerConnectionReceiver extends BroadcastReceiver {

02

@Override

03	public void onReceive(Context context, Intent intent) {

04	int status = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);

05	boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||

06	status == BatteryManager.BATTERY_STATUS_FULL;

07

08	int chargeFlag = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);

09	boolean usbCharge = chargeFlag == BATTERY_PLUGGED_USB;

10	boolean acCharge = chargeFlag == BATTERY_PLUGGED_AC;

11

}

12

}

1	//获取程序是否充电

2

3	int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS,-1);

4

5	boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||status == BatteryManager.BATTERY_STATUS_FULL;

1	// 充电方式，usb还是电源

2	int chargeFlag = battery.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);

3	boolean usbCharge = chargeFlag == BATTERY_PLUGGED_USB;

4	boolean acCharge = chargeFlag == BATTERY_PLUGGED_AC;

1	不断的检测电量也会影响电池的使用时间，我们可以这样做

 

1	<receiver android:name=".BatteryLevelReceiver">

2	<intent-filter>

3	<action android:name="android.intent.action.ACTION_BATTERY_LOW"/>   <action android:name="android.intent.action.ACTION_BATTERY_OKAY"/>   </intent-filter>

4	</receiver>

当电量低或者满时会触发

有时间再写确定和监测连接状态
