Question 1: For SDK encryption: Android application ID, expiration time encryption, SDK initialization return value is “-5”?
Reason：The verification failed.
Solution：
(1) Ensure that the application has permissions of read and write SD card.
Method: Add permissions in Mainfest.xml, Android 6.0 or above needs to be dynamically adapted.
Example:
(2) Replace the deepcam.key file
Method: Refer to the demo directory app/src/main/assets/key/deepcam.key
Example:
(3) Modify the application package name
Method: Open the “build.gradle” file in the App directory and find the “application Id”, and setting it to the registered package name.
Example:
- Registered package name
2. Replace the package name
(4) Mainfest.xml increases the key value
Method: Refer to <Meta-data> in Mainfest.xml in the demo, and the value is the registered App key value.
Example:
(5) Make sure you can get the cpuinfo information of the android device.
Method: The “Adb” command executes the “adb shell cat /proc/cpuinfo”, which can check the cpu information. In this step, you have to ensure the Serial number is not empty. The verification would fails if it is empty,.
Example:
(6) Make sure the device Mac address is not empty
Method: Entering the android device settings option, view “About Device”, view “WLAN MAC Address” or “Ethernet MAC Address”, and make sure at least one has a value.
Example:
RK3288
(7) Clear the cache and restart the app.
Method: Delete the /sdcard/deepcam directory, clear the cache, and restart the app, which can prevent authentication failure caused by improper use of deepcam.key.
