There is an app which i am running on android studio in debug mode. It is running fine and it stops at the breakpoint set, but when i press F6(Step Over) after the breakpoint i.e. Step Over again and again, it will execute till the end of that function and then stops the application and the debugger. But when i press F8(Resume prog) to resume the program, it works normally and even the functions after this breakpoints are called as expected and neither the debugger nor the application stops.
Any idea why it is happening in case of F6 only and not in F8?
Note:- Keymap is changed to Eclipse, so there is no point of shortcuts
in android f6 is not used for Debug please refer this key map for android studio here

I am used to compile the application on the emulator and when making any changes, I play the run button, the application gets closed on the emulator and replaced with the new version.
But recently this stopped working, the first time I open the emulator works fine, but if I press the Run button again I get:
Error while waiting for device: AVD Pixel_4_API_30 is already running.
If that is not the case, delete the files at
C:\Users\MyUser.android\avd/Pixel_4_API_30.avd/*.lock
and try again.
The thing is, yes, it is already running, and that's expected. I don't know why it does complain about it.
For now, I'm using the workaround of stopping the emulator every time I want to press the Run button so it gets started again.
Plus the restart button shows this message, which contradicts the run error message:
Apply Changes and Restart Activity (disabled: device not connected)
I downgraded the Android Studio version and now it detects my physical device and allows to rerun the app on the emulator.
It seems to be a bug on the latest version.
When I'm running an app in debug mode with Android Studio, is there a way that I can find out what line of code is currently being processed? By this I mean, is there a tool that works kind of like setting a breakpoint, but you don't have to set a breakpoint - you can just find out at any point in time what line of code is being executed?
The reason for this, is that sometimes you may want to debug intermittent hangs in your app. If your running in debug mode, and your app hangs, it would be useful to immediately find out what line of code it last processed, without having to plan ahead by setting breakpoints or trace calls
IntelliJ is my android development IDE.
And it help me to generate the apk.
One situation is:
The apk runs well when I debug with real phone.
But if I use run model ,it does not work.
Another situation is that:
The apk runs well the first time ,but if I press the home key long time and kill the app.
Then I go to the app icons board to click my app icon, it will stay on the screen "Waiting for debugger".
The "Waiting for debugger" message is because you have built the app for immediate debug. You pressed the debug button right? The app expects to be able to connect to the debugger immediately on launch. This is really useful if you want to debug something that happens immediately on launch.
If you don't need to debug immediately you can hit the "Play"/"Run" button in Android Studio. The app will still be built in debug mode so you can still start debugging later by pressing the "Attach Debugger" button. Pressing the debug button is like pressing the play button and immediately pressing the "Attach debugger" button.
If you want to test the app in Release mode, you can select "Build Variants" and choose release, you don't normally need this.
Here's an image showing the build variants menu and the run, debug and attach to debugger buttons:
But if I use run model ,it does not work.
I presume you mean with the emulator. The emulator can be tricky to get working, so I'll need more information about what isn't working to help
I am trying to debug an infinite loop in my program in android studio. I have a lot of breakpoints set up but every time I try to run it, it gets to a point where it just says "The application is running" and stalls out until the phone runs out of memory. What tool in Android studio is there to see the flow of the program? Specifically what methods are being called and which one is being called ad infinitum.
To see your code execution stopped on breakpoint, you need to run it in debug mode Shift+F9. Normal run (Shift+F10) is not affected by breakpoints.

I have configured a VD through Eclipse and it starts up fine. If I press F11 from one of my .java files in my application project, it starts up a new instance of the emulator and installs the app on it. However it does not open the app and if I manually open it and click on action buttons, it plainly is not linked up to the IDE for debugging as no break points get hit.
Other times when the emulator is open, F11 does the job of re-installing the app (after I manually uninstall it from the emulator), but again it does not attach as a debugger, just installs the app so I can run it.
Is there something basic I am doing wrong so that step-through debugging is not working?
Eclipse having option Skip All Breakpoints,
it might be possible you enable this option so you need to disable Skip All Breakpoints,
Option will appear when you will right click on project and trying to run it.
You can also do it by UI of eclipse , figure out this images. there are a option, if you toggle this button option it will behave disabe/ enable
