Hello!
I have finally achieve to install my app in two different ways:
1-Copying the app to the sd card:
After positioning myself on the app directory( in the android internal console), I tried:
# pm install app.apk and I received:
Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE].
This happened because the app wasn't copied on the correct sd partition.
After changing the location of the app I got another problem:
Failure[INSTALL_PARSE_FAILED_NO_CERTIFICATES]
I have solved this by creating a signed app,copying it and installing it again.(The first app wasn't a signed one).
2- Connecting the device to the pc (LINUX):
I have been able to connect it by following Eduardo's last post steps.
Thank you Eduardo, because testing the apps with the device directly connected to my pc will save me a lot of time.
Thanks also to everybody who has tried to help on solving this issue. If anybody has any question about the topic, I'll be willing to help you.
Regards,
Iker iMX.508.
