一个 到梦空间 抢活动的方法

能找到这里的应该都知道,这是个沙雕app,打着?的旗号,祸害大学生,还说自己是全国?研究中心,为了毕业,没办法…

这个方法需要ROOT,如果手机不能ROOT的就不用看啦

本来我已经卸载了这个沙雕app,但是突然想起来,好像可以弄个抢活动的玩玩,看了眼apk,360加固……遂断掉了改包的念头..

于是突然想到直接启动报名的那个activity,就可以领先别人一步点击报名,这样就会有更高的成功率…(实际证明,如果不能准确计算时间,这个方法应该比较慢)….

由于在AndroidManifest.xml中,报名的那个activity的exported值为false,故不能从其他app启动该activity。

但是如果权限为root的话,是可以启动的。

在这里用到的是am命令

这是am命令的帮助

根据这个帮助,很容易可以得到,我们的命令该长这样

am start-activity -n com.jingcai.apps.qualitydev/com.jingcai.apps.qualitydev.qualitync.activity_sign.Activity_SignActivity

后面的是包名和启动的activity,这个是和在app中通过intent启动别的app的activity所用到的componentName差不多的,activity的名字可以从各种app中获取到

但是这样还不行,还得像这个app发送一个参数,为activityId,并且想要启动成功,还需要root权限,所以正确的命令应该长这样

su -c am start-activity -n com.jingcai.apps.qualitydev/com.jingcai.apps.qualitydev.qualitync.activity_sign.Activity_SignActivity -e activityId 你要抢的活动id

怎么使用呢,手机下个终端模拟器,或者连上电脑使用adb执行都行….

执行完毕后会弹出一个报名的页面,在差不多到报名时间的时候疯狂点击即可

为了方便,我写了几行代码把他变成了个app
