Install apk manually on device : error 103

Question

I try to install an apk (build by IntelliJ) manually on my phone (GT-B5330 running Android 4.0.4).

• Intellij generate MyApp.apk (using Build > Artifact > Rebuild...)
• Phone setting : Security > Device Administration > Unknown sources is checked
• I uninstall existing "debug" version of MyApp on the phone
• I connect my phone to the pc with USB cable and transfert MyApp.apk to the phone sdcard.
• On the phone I browse the sdcard and click MyApp.apk
• I see the permissions required by MyApp and try to install it.
• I receive a message "Application not installed"

Looking at logcat I found those logs:

01-25 10:55:15.668: INFO/ApplicationPolicy(1448): isApplicationInstallationEnabled
01-25 10:55:15.668: WARN/PackageManager(1448): verifying app can be installed or not

01-25 10:55:16.148: DEBUG/InstallAppProgress(22326): Installation error code: -103

I tried to find the meaning of this error code -103 but I didn't find anything.

I'm wondering what can be wrong and how can I fix/investigate the issue?

Note that :

• when I run the from my IDE : it is installed and work properly.
• some native libs are packaged with MyApp.apk

Am I missing something obvious ? Other security setting to change ?

Any help will be greatly appreciate.

Answer 1

While running from the IDE, the apk is signed with the debug key.

I assume that you first mentioned build method might use another key or no one at all. None at all is my guess as otherwise you should have got a message that the signature differs.

Here is a screenshot to show how to sign an apk with IDEA12

Answer 2

You have already installed this app in your device? Because probably you are trying to install an application already exists, signed with a different key.
