BitmapFactory: Unable to decode stream: java.io.FileNotFoundException even when file IS actually there

Question

I\'m creating a simple app to take a picture. this is my code

Button b1;
ImageView iv;
String TAG = \"MAIN ACTIVITY\";

File photo;
private Uri mImageUri;


         


        

Answer 1

file:///storage/emulated/0/cameratest/picture459838058.jpg

Remove file:// because the decodeFile() expects a file system path.

/storage/emulated/0/cameratest/picture459838058.jpg

Answer 2

Replace mImageUri.toString() with mImageUri.getPath().

decodeFile expects a path, not an uri string.

Answer 3

Ok for me it was the file path was wrong so I needed to get the real filepath.

First

File file = new File(getPath(uri));

public String getPath (Uri uri)
{
    String[] projection = {MediaStore.Images.Media.DATA};
    Cursor cursor = getContentResolver().query(uri,
                                               projection,
                                               null,
                                               null,
                                               null);
    if (cursor == null)
        return null;
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String s = cursor.getString(column_index);
    cursor.close();
    return s;
}

Then Back To Uri

Uri newUri = Uri.fromFile(file);

This conversion to file and back to uri did the trick for me. I was receiving simple data from action.SEND.

Answer 4

Use BitmapFactory.decodeStream instead of BitmapFactory.decodeFile.

try ( InputStream is = new URL( file_url ).openStream() ) {
  Bitmap bitmap = BitmapFactory.decodeStream( is );
}
