网上搜了一些解决方案 但是不懂怎么操作

以下是网上找到的方法。很多地方都指示说是这样做，但是实在不懂怎么回事儿。请懂的前辈指导下。

这个错误的主要原因是ADT插件赋予APK文件debug签名时数字效验出错可能因为ADT版本不同、APK不是这台计算机生产的在模拟器或Android手机上， 解决的方法可以直接在真机中删除该程序，重新执行即可，或在shell中直接adb uninstall <package name>后重新安装。

[纠结的木棉花]

在tools下cmd：
adb uninstall 程序包
上面的异常说明你的系统里面已经有了这样一个程序~卸载试试~

[儿大不由爷]

已经安装过了，但是签名不同所以不行，可以卸载再安装，或者修改应用的版本号

[tfront]

uninstall
如果是push上去的系统程序，需要
adb remount
adb shell
cd /system/apps
找到你的那个程序的apk然后rm
exit然后再uninstall一遍才可以

我也有这个情况啊，我输入adb remount adb uninstall com.android.XXXX后总是报failure。。。

这个要怎么解决呢？
