Android Question dji app crashing

[shb777]

When I run Erel's drone mission, or my DJI app, connected to my drone, it always crashes the first time, then runs OK, usually the 2nd time, sometimes the third time. Any ideas why this would happen?

You need to post the error message from the logs.

but there's not gonna be an error message because i'm only running from my tablet. I'm running in release mode. I expect the app to crash when I'm not connected to the drone. Should I be using the Simulator or something else?

 

[shb777]

I'm writing your logs to a label on the app, and it's crashing in SDK_ProductChanged, saying no connected product. But the remote is saying it's connected, and giving the
correct battery level. Just now, after saying no connected product, it said product connected, and has been showing video and telemetry for a long time. So I'm assuming that even if SDK_ProductChanged returns no data, the app should keep running waiting for SDK_ProductChanged to be called again with data.

Make sure that bridge logger is enabled:

#BridgeLogger: True

You should run the app connected with B4A-Bridge and post the error message from the logs.

but the tablet has to be connected to the remote control, so it can't be connected to the pc except maybe via wifi. is that what you mean? I do have

#bridgelogger True

 

[DonManfred]

The tablet is connected to the remotecontrol over usb cable or not?
And the tablet can use wifi to use b4a bridge to install the app from your pc

Your PC is then able to get the log over b4a bridge

 

[shb777]

yes the tablet has to be connected to the remote control via cable when i'm testing my app. i typically don't use wifi to connect via the bridge because it was unreliable

This morning I was running the exact same project that was running OK last night, and it was crashing. Now, after leaving the tablet on for a while, and maybe the drone
and remote control have warmed up a little, it's running OK. Typically, when I fly the drone, I don't worry about having things "warm up".

Actually, my program is almost exactly like drone mission now. I'm re writing it, and have
only added mapfragment, and a few labels.

 

[shb777]

I've found that when I take the mapfragment out with the designer my app doesn't crash. when it's in it crashes. i haven't changed any code at all.

 

[shb777]

Does this look correct for my manifest

'************ Google Play Services Base ************
AddApplicationText(
   <activity android:name="com.google.android.gms.common.api.GoogleApiActivity"
  android:theme="@android:style/Theme.Translucent.NoTitleBar"
  android:exported="false"/>
    <meta-data
  android:name="com.google.android.gms.version"
  android:value="@integer/google_play_services_version" />
)
'************ Google Play Services Base (end) ************

I put gmap in drone mission and it's crashing. Here's the project.

 

[Erel]

You need to be able to see the logs. You will not be able to develop without them.

 

[shb777]

how do I do that?

 

[DonManfred]

See post #5

I did what you said here's the log:

That's better. Are you using an Android 5+ device? Might be a multidex issue.

 

[shb777]

yes it's a new tablet. it runs 7 or 8. what should i do? do i need to add this

#MultiDex: True

Actually, I already have this in.

 

[Erel]

Does it start working when you click on the app icon again?

 

[shb777]

no Like I've said, I've had the multidex statement in all along because my new app is based on drone mission
