We all spend a lot of time in the debugger, so this session teaches you about some of the powerful debugging features available in Android Studio. This talk should appeal to all, from beginners to experts and everybody in between.
01:23 - Log filtering / folding
05:13 - Conditional breakpoints
06:17 - Dependent breakpoints
07:16 - Suspend thread
09:07 - Evaluate and log
10:42 - Breakpoint groups
11:28 - Drop frame
12:34 - Mark object
14:10 - Evaluate expression
15:10 - Apply changes
17:23 - Analyze stacktrace
Here are some of the tips that we didn't have time to cover:
* Dragging a breakpoint brings its settings along with it
* Ctrl+drag makes a copy of a breakpoint
* You can set breakpoints on the closing brace of a function
* You can set breakpoints on fields / properties (called "field watchpoints")
* You can set a breakpoint on an interface method to break on all its implementations
* APK debugging → goo.gle/2BOk5mb
* Data views to control how data is displayed in the debugger → goo.gle/2MSyKmC
* How to use and understand the Overhead tab → goo.gle/32Ua8Q3

Excellent. So many ways to reduce the noise of the debugger that I didn't know existed.

Thanks a lot. I have been using evaluate expression before, and that is one of the coolest tool. I learnt a lot, can't wait to use them for my next debugging session.

1:08 This game should be the easter egg on Android 11 ! 11:53 About drop frame, could be nice that instead of going to what called the function, we could drag the current execution line to anywhere in the code (or at least in the current function). I think it was possible on Java for PC, no? They also talk about "time machine". Could be nice to have a debug-only function (in both code and in the IDE) that saves the current state, so that we could re-reach it. 16:50 An even more efficient solution to reach a "heavy" breakpoint would be to run the app normally, and make it switch to debug on the breakpoint, using `Debug.waitForDebugger()` .

Analyzing stacktrace is great. Also Drop frame could be very useful when applying changes.

Can you just keep the view of the IDE the presenter is working with? We don't need to see the room. Meanwhile we are missing parts where he points to a button and we have to guess which button he was referring to...

@AndroidDevelopers 2 жыл бұрын

Check out the guide here: developer.android.com/studio/debug. Android Studio runs both debuggers at once in dual mode. You'll want to make sure that you've disabled compiler optimizations on your C/C++ code to improve the way the debugger works..
