Only receiving the first few instruction events during route simulation

[aardvarkk]

Describe the bug

When I simulate a route, I only receive a few "new instruction event" callbacks and then they stop firing despite the route simulation continuing as normal.

Steps To Reproduce Steps to reproduce the behavior:

1. Start a simulated route
2. After a variable amount of time, new instruction callbacks stop being received

Expected behavior New instruction callbacks should be fired for every turn along the route

Smartphone (please complete the following information):

• Device: PDA
• OS: Android 9
• SDK Version: 3.17.2.132 (Premium Edition)

Additional context It seems like it's somehow time-related. It's variable -- sometimes I'll get the first 3 instructions, sometimes 4. I increased the speed of the simulated route and got an additional instruction along the path I hadn't yet received, so it's almost like I get about 10 seconds or so of new instruction events before they stop completely. I'm not seeing any errors popping up indicating any kind of problem.

I do not seem to have the same problem running my example in the emulator, so it seems related to either this specific device or all physical devices. I am going to test on another Android device to see if it performs better.

Scratch that. I am also able to reproduce this in the Pixel 2 emulator at API Level 30. The instructions work for a fair amount of time, but then the instruction events stop arriving at some point.

Hi @aardvarkk

Could you please try to reproduce it in voice-navigation sample? As I receive all instructions along the routes in this app. I simply added listener:

private NavigationManager.NewInstructionEventListener m_instructionEventListener =
            new NavigationManager.NewInstructionEventListener() {
                @Override
                public void onNewInstructionEvent() {
                    m_callbackCount++;
                    String info = "Received instruction #" + m_callbackCount;
                    Toast.makeText(m_activity, info, Toast.LENGTH_SHORT).show();
                }
            };

// start listening for navigation events
m_navigationManager.addNewInstructionEventListener(new WeakReference<>(m_instructionEventListener));

Also, you can download and select voice package within this app in order to hear instruction announcements during active navigation.

Please share your sample code which causes issues.
