Android Wear app not installing from the mobile package - mobile

Question

Yes, I have followed all the other instructions and links. My wearable app is definitely being packaged with the mobile one, but is not installing.
The debug version of the mobile.apk is 4.9MB and of wear.apk is 1.9MB. When I build signed release versions, the mobile.apk is 5.8MB so I believe the packaging is happening.
When I do an adb install of the mobile.apk on the handheld, I get the following errors in the logcat of the handheld (the app package is com.pipperpublishing.refwatch so note the strange refwatch-1 reference in the second error):

I have tried a factory reset of the watch, resyncing, etc etc. Any ideas?
Here's my mobile build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.pipperpublishing.refwatch"
minSdkVersion 14
targetSdkVersion 23
versionCode 203
versionName "0.2.03"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
wearApp project(':wear')

and my "wear" build.gradle:

Answer 1

Only using the release .apk file will the wear application get automatically installed. It wont work using the debug key.
In case the application is signed with a release key, then check whether the application already exists in the android wear device.

Answer 2

So, after multiple uninstalls and reinstalls, but without changing any code, the install is now working. Sometimes I have to "Resync applications" to see changes on the phone. The whole process seems quite clunky.
