How to debug “deep” crashes in Android?

I'm trying to debug an android crash that occurs without Java Stack tracing ... Java Stack Trace errors are very easy for me to fix ... but this error I get seems to crash inside the "NDK" or something, which is the deep inside of Android, I call ... I haven't made any changes to the NDK btw ... I just don't know what else to call this layer hehe.

Anyway, I'm mostly looking for advice on deep debugging methods, and not help on this particular problem ... because I doubt that I can publish all the source code ... so I just need to know how to set breakpoints on deep layers or any other methods to track deep crashes in their source ... so I will briefly describe the error and then publish LogCat.

I have an application with 7 events

Activity_INTRO
Activity_EULA
Activity_MAIN
Activity_Contact
Activity_News
Activity_Library
Activity_More

INTRO is proactive ... it disappears in some company logos ... after displaying them for a set time, it switches to EULA activity ... after the user accepts EULA, it goes to MAIN ... MAIN then creates a TabHost and fills it with four remaining actions

... , "" TabHost , ... Java, ASM , IP ... , , "", "", "", "... "

, , Activity_MAIN, INTRO EULA, ... - , - TabHost'ed. , , , ... () , ... , , :

INTRO EULA:

//Display the EULA

Intent newIntent = new Intent (avi, Activity_EULA.class);

startActivity (newIntent);

finish();



and EULA to MAIN:

Intent newIntent = new Intent (this, Activity_Main.class);

startActivity (newIntent);

finish();
