Errors while installing APK from Android shell

I ran into 2 error while trying to install an APK from the Android shell. Note the apk is on the Android filesystem and I am installing it from the shell, not using adb.

The first error I got was: INSTALL_FAILED_INVALID_URI

$ pm install myApp.apk
pkg: myApp.apk

This is because you need to give the full path to the apk, like:

$ pm install /sdcard/myApp.apk

The next error I got was INSTALL_FAILED_UID_CHANGED:

$ pm install /sdcard/myApp.apk
pkg: /sdcard/myApp.apk

I was installing over an existing app. The first thing I tried was to uninstall the app, but that didn’t work. I found that removing the data directory for the app solved my problem:

$ rm -rf /data/data/

Cocoapods – Generated duplicate UUIDs

I recently added another target to my Podfile to support tvOS. Here is an example of what the Podfile looks like:

source ‘’

target ‘AppiOS’ do
platform :ios, ‘9.0’
pod ‘AFNetworking’, ‘3.0.0-beta.1’

target ‘AppTV’ do
platform :tvos, ‘9.0’
pod ‘AFNetworking’, ‘3.0.0-beta.1’

I got this really long error complaining of duplicate UUIDS. Here is a shortened version:

[!] [Xcodeproj] Generated duplicate UUIDs:

PBXFileReference —
…. /Products/AFNetworking.framework

From what I understand, this deterministic UUIDs is a harmless warning and can be disabled by running the following command in the terminal. Then run pod install again.
