===========================================
1.要做的就是监听系统发出的broadcast
public class FlorenceText extends BroadcastReceiver{ public void onReceive(Context context, Intent intent) { if(Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())){ start(context); } } }
2.在AndroidMenifest.xml里还要将receiver加上, 并写明程序的入口就是FlorenceTest
<application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <receiver android:name=".main.FlorenceTest" android:exported="true" android:process=":remote"> <intent-filter > <action android:name="android.intent.action.BOOT_COMPLETED" /> <category android:name="android.intent.category.HOME"/> </intent-filter> </receiver> </application>
这样,程序就可以在开机时自动运行了
