Android应用开机自启动示例程序

当Android启动时,会发出一个系统广播,内容为ACTION_BOOT_COMPLETED,它的字符串常量表示为 android.intent.action.BOOT_COMPLETED。我们要做的是做好接收这个消息的准备,而实现的手段就是实现一个BroadcastReceiver。

public class BootBroadcast extends BroadcastReceiver{
private static final String ACTION = "android.intent.action.BOOT_COMPLETED";
private static final String TAG = "StartBroadcastReceiver";
@Override
public void onReceive(Context context, Intent intent){
Log.d(TAG,"开机启动了");
if (intent.getAction().equals(ACTION)){
Log.d(TAG,"开机启动了接收到了");
// Intent i = new Intent(context,MainActivity.class);
Intent newIntent = context.getPackageManager()
.getLaunchIntentForPackage("com.iotts.autostartdemo");
// i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(newIntent);
Log.d(TAG,"开机启动了接收到了");
}
}
}

可以默认创建一个Activity,来测试这段代码
