应用开机自启动的原理是监听开机广播android.intent.action.BOOT_COMPLETED, 监听到该广播时会启动进程,进入Application
1、在Manifest中声明广播
<receiver android:name=".server.BluetoothBootBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
</application>
声明权限
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
2、广播接收类BluetoothBootBroadcastReceiver
public class BluetoothBootBroadcastReceiver extends BroadcastReceiver {
private static final String TAG = "BluetoothBootBroadcastReceiver";
private static final boolean DBG = true;
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
if (DBG) {
Log.d(TAG, "onReceive BOOT_COMPLETED_ACTION");
}
}
}
}
3、Application中new广播接受器
4、运行流程
Android系统启动发出ACTION_BOOT_COMPLETED时,会启动进程,BluetoothBootBroadcastReceiver收到开机广播ACTION_BOOT_COMPLETED,
然后可以在收到广播时需要的事情。
