While running APK expansion file sample I just skiped checking CRC32 to avoide crc bug algorithm and its working very fine!! But while XAPK File validation shows in correct
It's not a best sloution but I got the solution by hard coding the
ProgressBar mPB; TextView mProgressPercent; TextView mProgressFraction;
in DownloaderActivity onPostExecute method of validationAsynctask
mPB.setMax(10);
mPB.setProgress(100);
mProgressPercent.setText(100 + "%");
mProgressFraction.setText("Download Completed Successfully");
