android系统在Manifest.permission中有这样一条RECEIVE_BOOT_COMPLETED的定义,当你自己的程序加入这个权限后,就可以在系统启动完毕后收到一条系统的广播,这个广播的标志为ACTION_BOOT_COMPLETED,因此我们只要定义一个BroadcastReceiver用来接收这个广播,然后加入自定义的动作即可。代码如下:
- public class LocationLoggerServiceManager extends BroadcastReceiver {
- public static final String TAG = "customTag";
- @Override
- public void onReceive(Context context, Intent intent) {
- if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
- ComponentName comp = new ComponentName(context.getPackageName(), MainActivity.class.getName());
- context.startActivity(new Intent().setComponent(comp).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
- } else {
- Log.e(TAG, "Received unexpected intent " + intent.toString());
- }
- }
- }
在AndroidManifest.xml中加入这个类的定义和权限说明
- <receiver
- android:name=".LocationLoggerServiceManager"
- android:enabled="true"
- android:exported="false"
- android:label="LocationLoggerServiceManager">
- <intent-filter>
- <action
- android:name="android.intent.action.BOOT_COMPLETED" />
- </intent-filter>
- </receiver>
- <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
OK,大功告成。这里演示的是启动一个activity,同理你也可以启动一个service.
