APIMonitor Not working for Android Play Store Apps

[prashantmaurya]

Tried apps like hike, byjus and khan academy from playstore. Repackaged apk is generated but this new apk gives error while running on emulator. Error: Unfortunately app stopped working.
I am running this script in APIMonitor to automate repackaging, installing and collecting logs.
PS: This works for toy apps.
#!/bin/bash
if [ -z "$1" ]
then
echo "./run.sh apk-path"
exit 1
