FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed

When the size of a single compressed file in the assets or raw directory exceeds 1024K, appt will forcibly process this file at compile time, so that we will receive a file when reading it at runtime

This file can not be opened as a file descriptor; it is probably compressed

The solution is to disable compression for this file extension:

1. Change your resource file suffix to the suffix listed above.

Add in build.gradle:

android {aaptOptions {noCompress "pdf"//your file extension}}

2. Use the -0 parameter on the command line to specify the file suffix that does not need to be compressed.There is currently no known way to pass the -0 parameter to aapt when you use ADT within Eclipse.

3. Divide your resource file into files below UNCOMPRESS_DATA_MAX(1M).
