I'm trying to build an application on Sencha Touch for android, so I use Cordova to put it on my device.
The problem I'm facing is that everything works fine on my computer, but on android, the device can not find and read the locales files for each stores (I've already test on other Android device).
Here is the error on logcat:
E/AndroidProtocolHandler: Unable to open asset URL: file:///android_asset/www/app/store/recipes/list.json?_dc=1481398604306&node=ext-data-treestore-1-root&page=1&start=0&limit=25
E/AndroidProtocolHandler: Unable to open asset URL: file:///android_asset/www/app/store/recipes/pates.json
And here is the store that I use to read "pates.json":
var ingredientsData = Ext.create('Ext.data.Store', {
model: 'fr.ESIR.GreenVentory.model.IngredientListModel',
autoLoad: true,
proxy: {
type: 'ajax',
noCache: false,
enablePagingParams: false,
limitParam: null,
url: "./app/store/recipes/pates.json",
reader: {
rootProperty: 'ingredients',
totalProperty: 'totalCount'
}
}
});
And the files that I try to load are locally stored in "app/store/recipes/"
If someone have a solution, it would be cool for me to know it
I resolve my own problem:
All the data was stored on app/store of the sencha application, and when I build the Android application with Cordova, it doesn't take the json file because I haven't specify the file location.
So I create a data folder on the project root, put my json file and the folders that contain them on the data folder.
Don't forget to update the differents references of your json files
After that, it still working on the web version, but not on Android, because cordova don't integrate your files. Cordova reads the app.json file that you have on the root of your project. Go to the "resources" section of the file. Normally you have something like this:
/**
* Extra resources to be copied along when build
*/
"resources": [
"resources/images",
"resources/icons",
"resources/startup",
"data/*",
"data/recipes"
]
Just add the location of the folder that contains your file and cordova should integrate them when it compiles

I wrote a script that allows you to read and write to a json file. As long as I tried the script in unity editor, I didn't have any problems. But when I switched to installing the application on an Android device, I can't find my json file.
The json file is called "playerData.json" and has been placed in a folder called "playerData.json".
This is the code for the path of the json file (working on unity but not working on android)
path = Application.streamingAssetsPath + "/playerData.json";
I tried using this string of code to get the code to work on android as well, but there is no way to get it to work.
path = System.IO.Path.Combine(Application.streamingAssetsPath, "/playerData.json");
I only wrote the line concerning the path as my android device cannot find the JSON file. Thanks everyone for the help!
Application.streamingAssetsPath does not work on Android and WebGL
It is not possible to access the StreamingAssets folder on WebGL and Android platforms. No file access is available on WebGL. Android uses a compressed .apk file. These platforms return a URL. Use the UnityWebRequest class to access the Assets.
There is a workaround though as mentioned using UnityWebRequest, can find an example in this Unity Answer
I have a NativeScript/Angular application that uses code sharing.
To make my project more organized, I have created a core folder that contains a sub-folder for routing:
Routes are defined in app.common.ts:
export const appRoutes: Routes = [
{ path: '', redirectTo: '/products', pathMatch: 'full' },
{
path: 'products',
loadChildren: '../products/products.module#ProductsModule'
}
]
Of particular interest is the module path shown in the following property:
loadChildren: '../products/products.module#ProductsModule'
Serving this in the browser using ng serve -o works fine.
Bundling this to run on Android using tns run android --bundle doesn't work as it can't find the module.
If I change the path to ~/app/products/products.module#ProductsModule, the Android app then runs, but the web application can't find the module.
If I then leave the file watcher running for the Android build and change the path back to ../products/products.module#ProductsModule, both Android and web work fine.
I don't want to move my routing files back to the src folder. I am also reluctant to include any hacks such as platform-driven path string mangling.
If you have any explanations as to why this is happening and/or a robust fix that isn't 'hacky', I'd be keen to hear it.
The problem was stemming from some quirks regarding the file watchers. When I change the path to the following, both platforms work fine:
../../products/products.module#ProductsModule
The reason I didn't select this path from the outset is because I used ~/app/products/products.module#ProductsModule to begin with and edited this to get the web build to work while the Android file watcher was still running.
With both the Android and web file watchers terminated and the path adjusted to the one provided above, they both work.
I am trying to generate source maps in the Gradle build process of a React Native app and read the source map file in the application.
I used this project as a starting point: https://github.com/philipshurpik/react-native-source-maps
I didn't succeed in including it as it is, so I tried to take and modify parts of it.
In app/gradle.build I added:
project.ext.react = [
extraPackagerArgs: ["--sourcemap-output", "$buildDir/intermediates/assets/release/index.map"]
]
and indeed when I'm running the release build I see the file index.map under android/app/build/intermediates/assets/release , but when I deploy the APK to a device or emulator, I can't see this file anywhere in Android's filesystem. For that matter, I also can't see the bundle file or any files that were in android/app/src/main/assets and I do see in android/app/build/intermediates/assets/release after build.
The application code uses https://github.com/itinance/react-native-fs to read the file. This is how I first check if the file exists:
const fileExists = await RNFS.existsAssets(`${RNFS.DocumentDirectoryPath}/index.map`)
and the file doesn't exist there. RNFS.DocumentDirectoryPath returns /data/user/0/mypackagename/files , which is empty when I check (using adb shell with root access).
What am I missing? How do I get the source map file to a location which will be available to the application to read?
Turned out the gradle.build part was fine, and in order to read the source map file I needed to use just the file name, like so: RNFS.existsAssets('index.map')
I want to wrap a react based web app which gets build using webpack in a
cordova container for an Android device. I successfully built the
cordova app for iOS and everything worked fine. However, when building
for android, static resources like images and fonts that are required in
javascript using webpack's file-loader, aren't loaded correctly.
The web view tries to load all resources like an image from
file:///android_asset/www/build/myImage.png, but logs a file not found
error. If I link - for example - the same image directly in the
index.html via an image tag, the image is loaded correctly, but changing
the publicPath attribute in my webpack config file didn't work.
Any help is very much appreciated.
Thanks a lot in advance
My brute force solution:
Pre-React Build: add "homepage": "./", to app’s package.json.
Post-React Build, and Pre-Cordova Run Android: in www/static/js, find/replace “static/media” with “android_asset/www/static/media” for all image/pdf files in the main###.js file (not the .map file).
My solution was to add "homepage": "/android_asset/www/" to package.json, it works perfectly with dynamic paths,
This code works in the simulator but not on my Android device:
local path = system.pathForFile("chinese_rules.db")
print("PATH:: " .. tostring( path ) )
When I run this code on my Galaxy S4 path returns nil.
My first thought was that it was some typo (case sensitivity) but I can't find any typo:
http://i59.tinypic.com/wlpu14.png
I can't find any reason why it should receive nil. This causes a problem as I can't load my database.
I have also tried this with the same result:
local path = system.pathForFile("chinese_rules.db", system.ResourceDirectory)
I have been able to load a path and load databases like this before.
Corona Build: 2013.2100 (2013.12.7)
Further reading the documentation I don't see that .db is a restricted file type:
Corona allows direct loading of images and audio files using the
appropriate APIs, but it has limited access to resource files on
Android using the file I/O APIs. Specifically, the following types can
not be read from the resources directory: .html, .htm., .3gp, .m4v,
.mp4,.png, .jpg, and .ttf.
http://docs.coronalabs.com/api/library/system/pathForFile.html
I found out the reason for the problem:
We are two that are working on this project and he had setup to use expansion files so two files was created (the main APK and the OBB expansion file) which I didn't notice and I only loaded the main APK file and I guess the database is in the OBB file. After setting not to use an expansion file the app works.
usesExpansionFile = false
