File Not Found... Selecting A Video From Gallery

I have both /document/video:5312 and content://com.android.providers.media.documents/document/video%3A5312 as 'URI' or 'absolute paths' to a video file that I selected f

Solution 1:

"URI" or "absolute paths" to a video file that I selected from gallery

Those are Uri values. They are not filesystem paths, nor can you get filesystem paths for them.

The file is NOT found.

That is because they are not files. content://com.android.providers.media.documents/document/video%3A5312 has a scheme of content, not file.

Similarly, https://stackoverflow.com/questions/41900707/file-not-found-selecting-a-video-from-gallery is not a file, as that Uri has a scheme of https.

How do I open it with File()?

You don't, any more than you open https://stackoverflow.com/questions/41900707/file-not-found-selecting-a-video-from-gallery using File.

Instead, you use ContentResolver and openInputStream() to get an InputStream on the content identified by the Uri, just as you might use OkHttp or HttpUrlConnection to get an InputStream on an httpsUri.

Solution 2:

Ok. Thank you.

Here's what I managed....

    String[] perms = {"android.permission. WRITE_EXTERNAL_STORAGE"};

    intpermsRequestCode=200;

   requestPermissions(perms, permsRequestCode);



  publicvoidconvertFile(Uri urx)throws IOException {

    ContentResolvertest= getContentResolver();
    InputStreaminitialStream=  test.openInputStream(urx);


    byte[] buffer = newbyte[initialStream.available()];
    initialStream.read(buffer);

    Filexpath= Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES);


    FiletargetFile=newFile(xpath, "/test.mp4");
    OutputStreamoutStream=newFileOutputStream(targetFile);
    outStream.write(buffer);
    uploadFile(targetFile.getPath());

}

@OverridepublicvoidonRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults){

    switch(permsRequestCode){

        case200:

            booleanwriteAccepted= grantResults[0]== PackageManager.PERMISSION_GRANTED;

            break;

    }

}

I get an EACES error upon trying to write my .mp4 file. Is there a way to "write it to memory" ? Or maybe you can resolve this issue.
