Intent FLAG_GRANT_READ_URI_PERMISSION Using FileProvider in Gingerbread

Question

I have an issue where I'm trying to attach multiple files from my internal storage to an email intent by providing them using a FileProvider declared in my manifest and granting the read uri permissions. Here is my code. Manifest ```

``` Intent Creation ``` emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE); emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] {"randomemailaddress"}); ArrayList uris = new ArrayList(); File directory = getFilesDir(); File[] list = directory.listFiles(); for (File f : list) { if (f.getName().contains("log") && f.getName().contains(".txt")) uris.add(FileProvide…

Accepted Answer

```
context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);

//revoke permisions
context.revokeUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
```

As a last resort, if you can't provide package name you can grant the permission to all apps that can handle specific intent:

```
//grant permisions for all apps that can handle given intent
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
...
List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
    String packageName = resolveInfo.activityInfo.packageName;
    context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
```
