FileNotFoundException: : open failed: ENOENT (No such file or directory)

[goodboywt]

I used GenericDraweeView like this ：
uri = Uri.parse("file://" + imagePath);
genericDraweeView.setImageURI(uri);

imagePathis a image's path like /data/data/com.coohuaclient/files/img/561e06dde99af1447898564884.mdata.

And I add GenericDraweeViews to a viewPager,but sometimes,some page display nothing but white.
I catch some log as follow,it said that the image file can't found,but the image is in my app's directory.How did this occur? Can you help us?

this is the appearance

what is the full path of your image, and what kind of format is it.
You may need to use https://developer.android.com/reference/android/os/Environment.html

[goodboywt]

File dir = new File(MainApplication.getInstance().getFilesDir(), IMG_NAME);
if (!dir.exists()) {
dir.mkdirs();
}
dir.getAbsolutePath();

I get the path like this, the images put in the data/data/[packagename]/files directory.And image's format is JPG,but we change the suffix to [mdata],is that influence Fresco to decode the picture?

[aagnes-zz]

You can try to query JPG path first. I think Fresco is able to decode the pic once if it can find the image file. You'll need to figure out the file path.
