Introduction

We're able to get a Uri from Camera, Gallery, Video Camera Intent. We will obtain a Uri from the intent then you can use it to get a temp File.

stream2File.java

// We can get input stream from uri.
InputStream inputStream = getContentResolver().openInputStream(uri);

public static File stream2File(InputStream in) throws IOException {
    File tmpFile = File.createTempFile("tmp", ".jpg");
    tmpFile.deleteOnExit();
    // compile "org.apache.directory.studio:org.apache.commons.io:2.4"
    IOUtils.copy(inputStream, new FileOutputStream(tmpFile));

    // You got a [tmpFile] from [inputStream].
    return tmpFilel;
}
