Android Question 1.png: open failed: ENOENT (No such file or directory)

Shay · Sep 14, 2018

I upgraded from B4A 6.x to 8.50 and tried to compile and getting the following errors on each file that start with number, such as 1.mp3, 1.png, etc..
why?

java.lang.RuntimeException: Unable to create service takziv.financhick.com.starter: java.lang.RuntimeException: java.io.FileNotFoundException: /storage/emulated/0/Android/data/takziv.financhick.com/files/virtual_assets/1.png: open failed: ENOENT (No such file or directory)

Hi All,

Same issue with a fresh install (8.50)

I try to compile and run « MyFirstProgram.b4a » in debug mode (galaxy S3 connected by usb) and I get the same error.

Thank you for your help

Shay · Sep 15, 2018

update: as stated by Olivier issue happens on debug mode, not on "Release" mode

Erel · Sep 16, 2018

Are you using the legacy debugger? Can you post the compilation dialog text?

Shay · Sep 16, 2018

I moved from 6.x to 8.50, so I am unaware of legacy none legacy mode
I am choosing from the drop down (release / debug, ..) so debug

Erel · Sep 16, 2018

You can check it under Tools - IDE Options.

Can you post the compilation dialog text?

Eduardo Enri · Sep 16, 2018

Same result with several projects even example projects as "AppCompatWithDynamicMenuAndBadge". Only in Debug mode.

Update:
if using legacy debug mode, it is working fine

Eduardo Enri · Sep 16, 2018

Erel explained a solution to a similar situation in this thread: https://www.b4x.com/android/forum/t...n-mode-“debug-rapid-”-b4a-3-50-version.38981/

Add this line to the main activity: #DebuggerForceStandardAssets: true

It is working now but means that this is a temporary solution.

Erel · Sep 17, 2018

Eduardo Enri said:

This is not a temporary solution. It disables a debugger optimization. You can safely use it.

@Shay which device are you using? Does it work if you add this line to the manifest editor:

B4X:

AddPermission(android.permission.WRITE_EXTERNAL_STORAGE)

?

Eduardo Enri · Sep 17, 2018

Certainly Erel, but I think that it is not a definitive solution for me, since I would like to return to the situation previous to the recent update of B4A where this command was not necessary in my project. Would it be possible?. Thanks.

Eduardo Enri · Sep 17, 2018

I tried adding this line to the manifiest editor and works too.

B4X:

AddPermission(android.permission.WRITE_EXTERNAL_STORAGE)

Thanks!

Erel · Sep 17, 2018

Create a new project with a layout file. Does it work properly in debug mode (without adding any permission)?

Eduardo Enri · Sep 17, 2018

Doesn't work.

I attach example project used.

Shay · Sep 17, 2018

@Erel same for me, simple project, 1 image in layout

I am using Asus tablet 7''
yes if adding this line to mainfest it solve the issue

Erel · Sep 18, 2018

It is a bug in B4A v8.50. Fixed here: https://www.b4x.com/android/forum/threads/updates-to-internal-libraries.59340/#post-613689

Shay · Sep 18, 2018

@Erel do I need to use the above solution or I can use the mainfest line for now?
and are you going to issue new b4a version soon with the fix?

Erel · Sep 18, 2018

It is better to use the updated debug.jar as it doesn't require a new permission.

Shay said:

Probably no.
