Distributing Android Apps to Wear Platform

#21

This is the android manifest fro the watch app (it is for a watch face app).

I think this line is also necessary
<uses-feature android:name=“android.hardware.type.watch”/>

See: https://docs.coronalabs.com/guide/distribution/buildSettings/index.html#app-features

That sounds like it might cover what you need.

Thanks Rob. I got a step closer by seeing the Android Wear option; however, the option is disabled. I am fairly sure it is related to Target levels below. Is there such an option in COrona to choose these levels:
All devices that are running Wear 2.0 are using Android 7.1.1 (API level 25). If your app only supports devices running Wear 2.0 or higher, the minimum and target API level should be 25. If your app supports both Wear 1.x and 2.0, the minimum and target API level can be 23. All Wear apps must target API level 23 or higher, so run-time permissions are required.

This is my build.setting:

It is strange, I got this review about the app from Google. I dont use openFile:

Hello Google Play Developer,

We reviewed Cycloop Watch, with package name com.jorc.CycLoopWatch, and found that your app uses software that contains security vulnerabilities for users. Apps with these vulnerabilities can expose user information or damage a user’s device, and may be considered to be in violation of our Malicious Behavior policy.

Below is the list of issues and the corresponding APK versions that were detected in your recent submission. Please migrate your apps to use the updated software as soon as possible and increment the version number of the upgraded APK.

Vulnerability APK Version(s) Deadline to fix
Vulnerability APK Version(s) Deadline to fix
Path Traversal
Your app(s) are using a content provider with an unsafe implementation of openFile.

To address this issue, follow the steps in this Google Help Center article.

4 November 17, 50352
To confirm you’ve upgraded correctly, submit the updated version of your app to the Play Console and check back after five hours. We’ll show a warning message if the app hasn’t been updated correctly.

While these vulnerabilities may not affect every app, it’s best to stay up to date on all security patches.

If you have technical questions about the vulnerability, you can post to Stack Overflow and use the tag “android-security.” For clarification on steps you need to take to resolve this issue, you can contact our developer support team.

Best,

The Google Play Team

What version of Corona are you using?

Rob

#28

2017.3100(2017.6.22)

#29

This is the message from google play developer console

#30

Just checking it now, the app is actually available on Google Play but it says no device is supported to install.

https://play.google.com/store/apps/details?id=com.jorc.CycLoopWatch&rdid=com.jorc.CycLoopWatch

#31

It says on Google Play:
Requires Android
4.0.3 and up

I need to comply with this though:
All devices that are running Wear 2.0 are using Android 7.1.1 (API level 25).
If your app only supports devices running Wear 2.0 or higher, the minimum and target API level should be 25.
If your app supports both Wear 1.x and 2.0, the minimum and target API level can be 23.
All Wear apps must target API level 23 or higher, so run-time permissions are required.

#32

Try this https://docs.coronalabs.com/guide/distribution/advancedSettings/index.html#android

#33

I added this but the app still shows 4.0.3 in Google Play.
 

android = { { minSdkVersion = "25",}, usesFeatures = { { name="android.hardware.location", required=false }, { name="android.hardware.location.gps", required=false }, { name="android.hardware.type.watch", required=true }, { name="com.google.android.wearable.standalone", required=true }, }, },
#34

The path traversal error was fixed in daily build 3145. The latest public build is 3194 and the current daily build is 3224. 

I would at a minimum recommend moving to 3194 through the current daily build has a few more fixes that could be better for you.

I tried the newer version Rod, but this line doesn’t seem to be implemented:
{ minSdkVersion = “25”,},

#36

FYI, it really helps to make sure your code is formatted well and when posting to the forums, use the code formatting tools so that your line indentions are maintained. You can use the blue <> button in the row with Bold, Italic, etc. and paste your code into the popup window. This will make it easier for people to read your code. If you’re not indenting your code, it’s a lot harder to spot problems.  For instance, I would think your build.settings should look like this:
 

settings = { android = { { minSdkVersion = "25",}, usesFeatures = { { name="android.hardware.location", required=false }, { name="android.hardware.location.gps", required=false }, { name="android.hardware.type.watch", required=true }, { name="com.google.android.wearable.standalone", required=true }, }, }, }

When you look at the formatted code you seem to have an unnamed table in the middle of the Android table.  I believe the build.settings you want is:

settings = { android = { minSdkVersion = "25", usesFeatures = { { name="android.hardware.location", required=false }, { name="android.hardware.location.gps", required=false }, { name="android.hardware.type.watch", required=true }, { name="com.google.android.wearable.standalone", required=true }, }, }, }

Thanks Rob. It works fine although still I cant publish to Android wear likely to be the design requirements.
