start a service on boot on Android

如果要在一開機時自動啟動一些service or app,
必須照一些步驟來作, 步驟如下:

1.在 manifest加上 permission: android.permission.RECEIVE_BOOT_COMPLETED

2.<receiver android:name="com.example.MyBroadcastReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

3.加上BroadcastReciver
package com.example;

public class MyBroadcastreceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction()))
    {
        Intent startServiceIntent = new Intent(context, MyService.class);
        context.startService(startServiceIntent);
    }
}

這樣就搞定了!

PS. 如果你是HTC手機, 可能要加上 <action android:name="android.intent.action.QUICKBOOT_POWERON" />
