Current Behavior

When you use the .share method to share a file of the app it throws the following error:

D/Capacitor: App paused E/DatabaseUtils: Writing exception to parcel java.lang.SecurityException: Permission Denial: reading androidx.core.content.FileProvider uri content://com.***.fileprovider/my_cache_images/log/log_2020-10-01_135743.txt from pid=30905, uid=1000 requires the provider be exported, or grantUriPermission() at android.content.ContentProvider.enforceReadPermissionInner(ContentProvider.java:729) at android.content.ContentProvider$Transport.enforceReadPermission(ContentProvider.java:602) at android.content.ContentProvider$Transport.query(ContentProvider.java:231) at android.content.ContentProviderNative.onTransact(ContentProviderNative.java:104) at android.os.Binder.execTransactInternal(Binder.java:1021) at android.os.Binder.execTransact(Binder.java:994)

Expected Behavior

Not throwing any error while trying to share a file. And being able to attach it to another apps like Gmail, Whatsapp, etc.

Code Reproduction

Having a file saved for example in cache folder using capacitor FileSystem plugin, try to share it using the Share plugin like:

let shareRet = await Share.share({ title: 'share-title', url: "file:///data/user/0/com.***/cache/log/log_2020-10-01_135743.txt", dialogTitle: 'share-dialog-title' });

Other Technical Details

npm --version output: 6.14.8

node --version output: v12.18.3

Additional Context

I am sure that this is because the plugin needs to add Intent.FLAG_GRANT_READ_URI_PERMISSION to the Chooser intent. See this example in stackoverflow: https://stackoverflow.com/a/59439316

I managed to solve it locally using the solution provided in that link and a few others that are pretty much the same. I cannot share it as pull request because I am not using GIT and I don’t have the time at all.

It basically consist in going to the Share.java file and setting the “fileUrl” as local variable variable just before the EXTRA_STREAM is added. Then, after the chooser Intent is created, you “grantUriPermission” to the packages by “queryIntentActivities” in the chooser, just like the example provided in stackoverflow.

2.4.3 is out with this fix.
