Open files from a Unity app natively on an Android device.

Unity Android Native File Opener

Open files from a Unity application natively on an Android device. Android recently added more security measures to restrict access to files from outside of an application. It used to be possible to open files with Unity's Application.OpenUrl() method on Android but now it requires a little more work to achive this. This plugin has been tested on Android Version 8, Unity Version 2018.2.17f1, and the "Internal" build system.

How to set it up:

• Download the Unity package here: UnityAndroidNativeFileOpener UnityPackage
• OR
• Clone this repo into your Assets folder

How to use the example:

• Add an AndroidManifest.xml file into the Assets/Plugins/Android folder
• If you do not have an AndroidManifest.xml already, you can find the Unity generated Android Manifest file in your ProjectName/Temp/StagingArea after you build the project once.
• Nest the below snippet inside of the AndroidManifest's <application></application>: tag.

<provider
  android:name="com.cartoontexas.andyr.unityplugin.UnitySSContentProvider"
  android:authorities="a_very_unique_name"
  android:exported="false"
  android:grantUriPermissions="true" />

• The android:authorities attribute should be a unique name, make this your app bundleID to assure uniqueness.
• Open example scene: "AndroidNativeFileOpenerExample"
• Add the example scene to your build settings and build to your device.
• When done, open app, tap the scene and a frog GIF should be downloaded locally and appear in your default Android GIF viewer.
• Feel free to try the other examples in the example script which can be uncommented and used.

How to use the API:

• Prepare the build using the steps above.
• Create a reference to a file on your device.
• Insert AndroidContentOpenerWrapper.OpenContent(pathToYourLocalFile); in your code.

unityandroidnativefileopener's Issues

Can't use in multiple apps. INSTALL_FAILED_CONFLICTING_PROVIDER . Can't install because provider name com.company.product.fileprovider

Do we need to recompile the java source and change an authority name or something for each app we want to use this in for them all to be simultaneously installed on a device? I am getting this when trying to install a second app on a device that already has an app installed using this asset.

INSTALL_FAILED_CONFLICTING_PROVIDER . Can't install because provider name com.company.product.fileprovider is already used in [first app]

Not sure where to change "com.company.product.fileprovider"

Doesn't work with PDF

I could do it with an image using this code:

 void LoadImage()
       {
           string filename = "vuzix.png";
           string path = Path.Combine(Application.persistentDataPath, filename);
           LoadContent(path);
       }
    void LoadContent(string path)
        {
            AndroidContentOpenerWrapper.OpenContent(path); //path must be path/to/file.filetype
        }

But whenever i try with a pdf, it says the file is corrupted and i can not open it in my android device

UPDATE:
I realized this only happens when i try to open a powerpoint converted to pdf file

I tried using a sample pdf file and it worked well

What could be the issue and possible solution?

Is it possible to open a directory?

Is it possible to open a directory using androids default file explorer?
TIA
