在模拟器中对Android 操作系统进行相应的编写,可以帮助我们实现应用程序的开机自启动功能。在这里我们就来通过一段代码充分的掌握Android开机自启动的相关实现方法,以帮助大家掌握这一应用。
1.定义一个BroadcastReceiver
Java代码
- public class BootReceiver extends BroadcastReceiver {
- public void onReceive(Context ctx, Intent intent) {
- Log.d("BootReceiver", "system boot completed");
- //start activity
- String action="android.intent.action.MAIN";
- String category="android.intent.category.LAUNCHER";
- Intent myi=new Intent(ctx,CustomDialog.class);
- myi.setAction(action);
- myi.addCategory(category);
- myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
- ctx.startActivity(myi);
- //start service
- Intent s=new Intent(ctx,MyService.class);
- ctx.startService(s);
- }
- }
- public class BootReceiver extends BroadcastReceiver {
- public void onReceive(Context ctx, Intent intent) {
- Log.d("BootReceiver", "system boot completed");
- //start activity
- String action="android.intent.action.MAIN";
- String category="android.intent.category.LAUNCHER";
- Intent myi=new Intent(ctx,CustomDialog.class);
- myi.setAction(action);
- myi.addCategory(category);
- myi.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
- ctx.startActivity(myi);
- //start service
- Intent s=new Intent(ctx,MyService.class);
- ctx.startService(s);
- }
- }
2.配置Receiver的许可,允许接收系统启动消息,在AndroidManifest.xml中:
Xml代码
- < uses-permission android:name=
"android.permission.RECEIVE_BOOT_COMPLETED"/>- < uses-permission android:name=
"android.permission.RECEIVE_BOOT_COMPLETED"/>
3.配置Receiver,可以接收系统启动消息,在AndroidManifest.xml中
Android开机自启动的Xml代码
- < receiver android:name=".app.BootReceiver">
- < intent-filter>
- < action android:name="android.intent.action.BOOT_COMPLETED"/>
- < category android:name="android.intent.category.HOME" />
- < /intent-filter>
- < /receiver>
- < receiver android:name=".app.BootReceiver">
- < intent-filter>
- < action android:name="android.intent.action.BOOT_COMPLETED"/>
- < category android:name="android.intent.category.HOME" />
- < /intent-filter>
- < /receiver>
4.启动模拟器,可以看到系统启动后,弹出一个对话框。
