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);
}
}
复制代码
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"/>
复制代码
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>
复制代码
4.启动模拟器,可以看到系统启动后,弹出一个对话框。
