Application not installed when i try to autoupdate

问题

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"?>

回答1:

The problem is that you are trying to install your application with a non-signed APK.

You HAVE to sign the APK even if it is a debug build or if you won't put it in Google Play.

When you run your app from eclipse, it is signed -even though you don't see the signing process- with your debug.keystore.

ALL apps MUST be signed before you install them on a device. ALWAYS. That suffers no exception.

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
