net::ERR_UNKNOWN_URL_SCHEME

[roedoejet]

Hi there,

Looking for some help debugging an issue with the plugin. I've added the plugin to my project as described for cordova 6.5 but the content:// URL scheme is still not recognized. My obb is a stored zip with one folder called "audio".

content://com.firstvoices.lilwat_fphlcc/audio/183Sounds20060713173801859seal_lil.mp3:1 GET content://com.firstvoices.lilwat_fphlcc/audio/183Sounds20060713173801859seal_lil.mp3 net::ERR_UNKNOWN_URL_SCHEME

Thank you!

I assumed this has something to do with the whitelist plugin, but I followed the instruction:

• I added <meta http-equiv="Content-Security-Policy" content="* * 'self' default-src 'unsafe-inline' 'unsafe-eval' http://* https://* data: cdvfile://* content://*;"> to my index.html
• I removed whitelist and added this version https://github.com/agamemnus/cordova-plugin-whitelist
• this is my config.xml:

[agamemnus]

Do you have the Cordova Media plugin installed?

[roedoejet]

No I don't, am currently calling my audio with HTMLAudioElement:

srcURL = "content://com.firstvoices.lilwat_fphlcc/audio/" + src
var audio = new Audio(srcURL);
audio.play()

[agamemnus]

Try removing the whitelist plugin entirely and modifying the java file to ignore it.. let me find the code..

[agamemnus]

(Might be a few minutes, kind of getting pulled in all directions right now)

[agamemnus]

Also, try seeing if you can get any other format to work to rule out other issues... PNGs? Text files?

[roedoejet]

Tried with 'jpg' and same error:

content://com.firstvoices.lilwat_fphlcc/audio/test.jpg Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME

[agamemnus]

Maybe the underscore is doing it? I really don't know. Try text files also.

[roedoejet]

Same error with .txt ...

[agamemnus]

Try removing the underscore...

[roedoejet]

Unfortunately the same thing: content://com.firstvoices.lilwatfphlcc/audio/test.jpg Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME

[agamemnus]

Change out this file:

https://github.com/agamemnus/cordova-plugin-whitelist/blob/master/src/android/WhitelistPlugin.java

See what happens if you have shouldAllowNavigation, shouldAllowRequest, and shouldOpenExternalUrl to simply return true.

[roedoejet]

Same error.

[agamemnus]

And text files don't work either?

[roedoejet]

Nope.

content://com.firstvoices.lilwatfphlcc/audio/test.txt:1 GET content://com.firstvoices.lilwatfphlcc/audio/test.txt net::ERR_UNKNOWN_URL_SCHEME

I just saw in a folder called "test-project-instructions-and-test-obb" in the plugin there's a step that's not included on the repo markdown. It says to add: android.library.reference.2=../../plugins/com.flyingsoftgames.xapkreader/android-sdk/extras/google/play_apk_expansion/downloader_library

to /platforms/android/project.properties

But I already have a value for that (see below), should I change it or is the above for testing with Google Play or another version?

target=android-25
android.library.reference.1=CordovaLib
cordova.system.library.1=com.google.android.gms:play-services-base:+
android.library.reference.2=com.flyingsoftgames.xapkreader/lilwatfphlcc-downloader_library
android.library.reference.3=com.flyingsoftgames.xapkreader/lilwatfphlcc-library
cordova.gradle.include.1=cordova-plugin-crosswalk-webview/lilwatfphlcc-xwalk.gradle

[agamemnus]

This is for an older version. That should be removed.

Is your obb uncompressed?

[roedoejet]

Yes, I used 7zip and set the compression level to "store"

[agamemnus]

There must be something simple we are missing. Can you create a small sample project based on your settings that I can run?

[roedoejet]

Sure. You can clone the sandbox I have for the app here: https://github.com/roedoejet/lilwat-test.git

I'm calling the audio in controllers.js and have the img and text in www/templates/search.html

Or do you want something with fewer bells and whistles? This way you have what I have.

[roedoejet]

I've got to run out for a couple hours soon to another job but I'll be back in a few hours. I really appreciate you looking at this!

[agamemnus]

I assume you are testing this with Android... are you using the latest Android platform version, or which version? Your code doesn't say.

[roedoejet]

testing on a device running 5.1

[agamemnus]

Also -- the obb file -- it's not there.

[roedoejet]

Oops. Sorry about that. just added it but with most of the audio taken out. There are three files, audio/183Sounds20060420153235640knife_lil.mp3, audio/test.jpg, audio/test.txt

[agamemnus]

Thx.

[agamemnus]

Downloaded it and installed latest Android platform, but didn't test.... please remind me tomorrow...

[roedoejet]

Ok great. thanks, I'll do that.

[roedoejet]

Any update on this? ... a friendly reminder :)

[agamemnus]

Checking now.

[agamemnus]

Maven? Might this be an issue?

[agamemnus]

No, that isn't it. Still checking a few different things.

[agamemnus]

Here is the problem: you do not have the File plugin installed, and for some reason your whitelist plugin is some random old dev version.

[roedoejet]

Huh, I didn't know I needed the File plugin, but that makes sense. The whitelist plugin I added was the one here which is listed on the readme, is that not right? https://github.com/agamemnus/cordova-plugin-whitelist

[agamemnus]

Oh, weird. I had no idea it was a dev version... but it IS old. :P

[roedoejet]

lol yes, so is it still required or does the newer version/main repo of cordova-plugin-whitelist work?

[agamemnus]

I did do a few different things.

If that still doesn't work, try instalilng a clean whitelist plugin as well, and try this for a meta tag: <meta http-equiv="Content-Security-Policy" content="default-src * 'self' 'unsafe-inline' http://* https://* 'unsafe-eval';">

[agamemnus]

No, it's not required if you have the various tags to change the security policy, etc.

[agamemnus]

You could also just delete the plugin...

[roedoejet]

Ok, I got the net::ERR_UNKNOWN_URL_SCHEME error to go away by removing the whitelist plugin altogether and by using the updated meta tag above. Now I'm getting 404's :( did the content actually come through for you? Thanks so much again for looking into this. I'll keep looking into it.

[agamemnus]

It did. You added the File plugin?

[agamemnus]

Update your code on github and I'll look at it again. I did do a number of things which might have had an effect...

[roedoejet]

Yep. I added the File plugin. It looks like the cordova-compat plugin got installed as a dependency or something. I've updated the repo with my changes

[agamemnus]

Ok, give me a bit and I will try again.

[roedoejet]

thanks!

[agamemnus]

It'll be tomorrow. I'm stuck on a bug (?) in another library and very tired. Sry.

[roedoejet]

no problem. you could also make a pull request to the repo with your local copy and I can try and see what other changes you made. g'night!

[roedoejet]

any luck? I'm heading out to work but will be back this afternoon/evening to have another look. Had me stumped yesterday.

[agamemnus]

I was busy all day yesterday. I am looking now, that I am wrapping up my bug work for the other project.

[roedoejet]

OK, no problem. Again, I really appreciate you looking into this. Be back in a few hours.

[agamemnus]

It's not working. I keep having issues with Error: Unexpected end of JSON input when I try to add the android platform, etc.
