Android Question Error Application not installed

[ibra939]

I finish design my application but when i create apk i make Compile (without siging ) the problem when i take the apk and rename it to m.apk i installed but showing this message Application not installed ?

how i make sure to work my apk ....?

what is Privete sing key doing ?

how i solve this "Application not installed"? i try example program same problem .

You should not normally use the Compile without signing option.

If you want to upload your app to Google Play then you need to follow these instructions: Signing your application before uploading to Google Play

Otherwise you can use any key you like.

Are you installing with B4A-Bridge? Try to first uninstall the existing app.

 

[ibra939]

I will ...Thanks Erel for your replay

Another reason is when you use the same package name for several apps. The Android think's it is the same app and then has a problem because it is another.

Install will also fail if you use more than one private sign-keys and want to install an app which is already installed but with another sign-key.

Isso foi o que resolveu o problema no meu caso. (<= Portuguese)

Hello,

I have a problem with the "Application Not Installed" message.
I'm not able to install the application but the aplications its not installed on the device.
This start do happening since I change my rom. But the same rom works on another device.
Don't know it there is any conflit file remaining on the device.

Does any body else have the same problem?

 

[DonManfred]

Most probably you need to make a factory-reset if you change the rom.
Sometimes a "Clear Dalvik-Cache" works too but the prefered way is a factory reset...

If i change my rom from Rom X to ROm Y (another rom, not just a new version) then i always do a factory-reset AND Clear Dalvik Cache.
If i just update a rom from version X to a newer one (but the SAME rom)) then i try first JUST clearing the dalvik cache....

Thanks DonManfred,

I did a factory reset, cache format and even formated dalvik when I change to cyanogenmod.
By the way its android 5.0.2, but then again it worked on another device with same rom.

I can that try reset every thing again and see if it solves.

Will reply again after...

Thanks for the tip

Hi again,

Still having the same problem, not able to install the app, and the app its not installed on the device.
Having dificulty to find the reason to this.

Can anybody help me?

 

[Erel]

Try to connect to the device with USB debug mode. It will give you more information about the error.

 

[DarkAngel]

Thank you Erel,

That helped, I had to turn "#CanInstallToExternalStorage:" to FALSE and now the application installed normally.
Thanks a lot .
