There is no application.cryptolog. in /data/data/com.example.aes/cache/

[Rocksnake]

I followed the instructions in the README and executed the commands in order, but when I reached the 'Collect the logs' step, 'cryptolog | failed' was printed. By looking at the script file, I found the problem was that there was no no application.cryptolog. in /data/data/com.example.aes/cache/, which led to The run_cmd function returns Error, I want to know how to solve it.

Thanks in advance.

Learn from your previous Issue, I just run the test application that is included in the folder app-test, but it still was error.

Hi, can you please check if there are other files in the directory /data/data/com.example.aes/? There should be a file called aes.log in one of the subdirectories. Can you confirm that the file aes.log is there? This is to make sure that the application was executed successfully. Can you report the content of this file?

[Rocksnake]

Yeah, there is file aes.log in the directory /data/data/com.example.aes/, and the content is:

Ok, great. Can you please go inside the directory android-emu/libcore and run the command git status?

I created the emulator manually and did not use the method in the README, so there is no android-emu directory in my root directory. I didn't execute these commands in the picture below.

Thanks! Sorry, but you need to create the emulator by using the method explained in the README. We modified the Java library to print the log. If you use a different emulator, you use the standard Java library and therefore the file application.cryptolog is not created.

Okay, thanks for your reply, I will try your method first, and then tell you the result of my attempt

Little personal suggestion is that u can add this requirement which need to create the emulator as README doing to the supplementary document, so that others wont meet the same problem as above ~~ Great thanks a lot ~~

Hi, could you please provide the modified Java library

Maybe you provided, but I didn't find it, could you please tell me where it is

Hi, if you build the emulator as explained in the instructions (the emulator you run from the directory emulator-emu that is created with the script scripts/setup/setup_emu.py) you will run your applications with our modified Java library. You can find the modifications to the Java library in scripts/deltas/libcore/ojluni/src/main/java. Thanks

Many thanks for your reply and guide

Hi, I built the emulator as explained in the structions, but now I have a problem. When I entered the script "emulator" or "emulator -writable-system", a line of instruction, “emulator: ERROR: No initial system image for this configuration”, will appear.
Then I searched it in google, but no satisfying results occured. Could you please give me some guidance? Many thanks!

Hi, I think there is some sort of issue with the compilation process.
Please go inside the directory android-emu and then do the following:

source ./build/envsetup.sh
lunch sdk_phone_x86-userdebug
make

This re-compiles the emulator. Is the compilation successful?

Thanks
