How to share image to viber app via file provider?

Question

I am using folowing code below to share images to wanted apps, which works well for most of the apps, except viber. Whenever I am trying to share image to viber, viber crashes with folliwng error:

My Uriess looks like content://com.myapp.fileprovider/share_images/nxt_emoji_26.png
code

public class ShareSmile {
  public static void share(Context context, int id, String selectedPackage) {
    String name = context.getResources().getResourceEntryName(id);
    try{
    if (name.contains("ic_")) {
      name = name.replace("ic_", "");
      File imagePath = new File(context.getFilesDir(), "image_assets/smiles");
      File newFile = new File(imagePath, name + ".png");
      Uri contentUri =
          FileProvider.getUriForFile(context, "com.myapp.fileprovider", newFile);
      Intent shareIntent = shareImage(contentUri,context);
      shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

      if (TextUtils.isEmpty(selectedPackage)) {
        //create chooser
       Intent sendIntent= Intent.createChooser(shareIntent, context.getString(R.string.send_via));
        sendIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(sendIntent);
      } else {
        //send to specific app
        shareIntent.setPackage(selectedPackage);
        context.startActivity(shareIntent);
      }
    }}catch (Exception e){
      HashMap<String,Boolean> map = MyPrefs.getSupportedApss(context);
      map.put(selectedPackage,false);

      Toast.makeText(context, R.string.share_smile_error,Toast.LENGTH_LONG).show();
    }
  }

  public static Intent shareImage(Uri uri,Context context) {
    Intent shareIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
      shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    } else {
      shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_DOCUMENT);
    }
    shareIntent.setType("image/png");
    ArrayList<Uri> streamUris = new ArrayList<>();
    streamUris.add(uri);
    shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, streamUris);
    //grant permission to access fileprovider
    List<ResolveInfo> resInfoList = context.getPackageManager()
        .queryIntentActivities(shareIntent, 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);
    }
    return shareIntent;
  }
}

The authors of Viber are inexperienced and think that all content Uri values come from the MediaStore, and so they are querying for a _data column that does not exist.

My LegacyCompatCursorWrapper can be used with FileProvider to try to improve compatibility with buggy apps like Viber, based off of the approach shown in this Stack Overflow answer. This sample app demonstrates the use of LegacyCompatCursorWrapper. You subclass FileProvider, override query(), and wrap the Cursor returned by super.query() in a LegacyCompatCursorWrapper:

package com.commonsware.android.cp.v4file;

import android.database.Cursor;
import android.net.Uri;
import android.support.v4.content.FileProvider;
import com.commonsware.cwac.provider.LegacyCompatCursorWrapper;

public class LegacyCompatFileProvider extends FileProvider {
  @Override
  public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
    return(new LegacyCompatCursorWrapper(super.query(uri, projection, selection, selectionArgs, sortOrder)));
  }
}

Then, register your FileProvider subclass in the manifest and otherwise use it like you would FileProvider.
