jImageView Cause App Crash

[Sirius Black]

Hi Guys,

I tried to create new sample app using the same method of the sample "App Compat Navigation Drawer Demo1"

Everything is working normally when I used jButton or jImageButton. But app always crash if I using jImageView as a button. I replace the jButton with the jImageView  in order to swith another panel (just like the demo), and when I click the jImageView the app will stopped.

I tried to see the log cat, and here are the logs:

I attached the .pas dan .lfm files

I just compiled your app. API 26. Works as expected. No crash when using image or button to get menu2.
I added this line to show more info:

Code: Pascal  [Select][+][-]

1. procedure TAndroidModule1.ivmenuClick(Sender: TObject);
2. begin
3.   Menu2;
4.   AndroidModule2.jTextView1.SetText('Got here by imageview');
5. end;
6.  

[Sirius Black]

I'm using API 28 with aarch64. Can it cause the problem?

Btw, have you tried several time? close the app, and running again for several times

[DonAlfredo]

No problem on aarch64.
Here is my apk:
https://github.com/LongDirtyAnimAlf/fpcupdeluxe/releases/download/patches_v1.0/AppLAMWProject23-arm64-v8a-debug.apk
if you want to try for yourself.

[Sirius Black]

Thanks for the APK. I tried to run it on my phone (mi 9), but it still force close. I attached the screenshots

[DonAlfredo]

Mmmm ...
I am running on Android 8. You are running on Android 9. Both aarch64. (nice phone btw)
The apk is build with API28.
For me, the crash is a mystery. There are no permissions involved.
So, we need a better crash log.
I am using monitor.bat, located here:
C:\.......\AppData\Local\Android\Sdk\tools\monitor.bat

[Sirius Black]

(nice phone btw)

thank you

C:\.......\AppData\Local\Android\Sdk\tools\monitor.bat

how to use it?

[DonAlfredo]

You need the logcat.
See screenshot included.

[Sirius Black]

Since I can't run monitor.bat, so I grab the logcat from adb shell, here are the results

[DonAlfredo]

I am sorry, but this is by far not enough debug-info (for me).
The info must contain (detailed) messages about the null-pointer and more.

[Sirius Black]

so that's mean I have to grab all the logcat information without filter the app only?

[DonAlfredo]

Yes.
All the red lines, without filtering !!

[Sirius Black]

I attached the logcat file. Is this contain the information that you need? thanks

[DonAlfredo]

That is a good log ! Now the next step.

I have made a debug-apk of your app.
https://github.com/LongDirtyAnimAlf/fpcupdeluxe/releases/download/patches_v1.0/AppLAMWProject23-arm64-v8a-debug.apk
Install and run it.
