我有我的应用程序的自动更新的更新自己，我开始练习这种方式：

 意向意图=新意图（Intent.ACTION_VIEW）;intent.setDataAndType（Uri.parse（文件：//+鲁塔+NameApp.apk），应用程序/ vnd.android.package归档）;intent.addFlags（intent.FLAG_ACTIVITY_NEW_TASK）;mContext.startActivity（意向）; 

问题是，当我尝试安装它，它说：没有安装应用程序我搜索有关这一点，人们说我必须改变版本code和版本的名字，我做到了，但仍然不工作，有是我的清单

解决方案

解决了，感谢OCUS引导我到解决方案

问题是，认证是不一样的，当你唱APK，当你调试它，所以你需要手动通过APK安装它，然后，你就可以正常自动更新

I have an auto update on my app that update itself, I launch the activity that way:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file://"+ruta+"NameApp.apk"), "application/vnd.android.package-archive");
intent.addFlags(intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(intent);

the problem is when I try to install it it said "Application not installed" I searched information about this and the people said that I must change version code and version name and I did it but still doesnt work, there is my manifest

<?xml version="1.0" encoding="utf-8"?>

06-25 16:25:05.132: E/PackageParser(2510): Package com.name.name has no certificates at entry res/drawable/boton_continuar_pago.png; ignoring!

Solved, thanks to OcuS to guide me to the solution

The problem was that the certification is not the same when you sing the apk, and when you debug it , so you need to pass manually the apk , install it and then, you can autoupdate normally
