Gallery can't open content uri image file on android 7.0

In my app, I show a list of posts where posts may have image. When user clicks on the post image, the create chooser shows available options like “photo”, “gallery”. My question is,why can't gallery open the image on android 7.0 or API 24 and above? I get an error “can not open file.” On API level 23 and below, I provide actual file path which seems to be working fine. I confirmed following things before posting this question.Interesting part is "Photo" could open it.

  1. I get the proper content uri using FileProvider. My uri looks like this:

    content://package.fileprovider/attachment/filename

  2. I am using the proper mime type.

  3. I am using proper intent and permission flags.Please see the below code:

Intent myIntent = new Intent(Intent.ACTION_VIEW); myIntent.putExtra(ShareCompat.EXTRA_CALLING_PACKAGE, getActivity().getPackageName()); myIntent.putExtra(ShareCompat.EXTRA_CALLING_ACTIVITY, getActivity().getComponentName());

myIntent.setDataAndType(uri, mimeType); myIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); startActivity(Intent.createChooser(myIntent, "Open file:"));

Only for Android API 24 above - Nougat device

 File file = new File(String.valueOf(path), imageName+".png"); //it is image file name.
 if(Build.VERSION.SDK_INT>=24){ 
      Intent intent = new Intent();

      intent.setAction(Intent.ACTION_VIEW);

      intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); //must provide

      Uri photoUri = FileProvider.getUriForFile(YourCurrentActivity.this, 
                      android.support.v4.BuildConfig.APPLICATION_ID + 
                      ".fileprovider", finalFile);

      intent.setData(photoUri);

      YourCurrentActivity.this.startActivity(intent);
 }

Maybe on Nougat you need to take permission from a user to read and write. Your code will work below N. So ask user to grant read permission and also check for FileProvider you will need that too.

You can open file URI by adding this to your Application:

if(Build.VERSION.SDK_INT>=24){
    try{
        Method m = StrictMode.class.getMethod("disableDeathOnFileUriExposure");
        m.invoke(null);
    }catch(Exception e){
        e.printStackTrace();
    }
}

Content may be the new thing, but in my opinion there aren't enough 7.0 devices active compared to lower API devices to justify the non-use of this deprecated method. 7.0 devices can still use this too, quiet well.
