The easiest solution today is to used Apache common io :

http://commons.apache.org/proper/commons-io/javadocs/api-release/org/apache/commons/io/FileUtils.html#readFileToByteArray(java.io.File)

byte bytes[] = FileUtils.readFileToByteArray(photoFile)

The only drawback is to add this dependency in your build.gradle app :

implementation 'commons-io:commons-io:2.5'
