Android Question Share image and text Social Media

ilan · Mar 8, 2018

hi

i searching for a while on the forum for a solution to share content (image + text) to social media and i have also tried some but cannot find something that is really working.

i just would like to share an image and text to facebook, twitter, WhatsApp, email,..

b4i has a great library that works perfect but i cannot find something similar for b4a.

any suggestions?

it should work on any android version (at least android and up incl. android 8)

thanx

See my answer here: https://www.b4x.com/android/forum/t...le-with-fileprovider-share.78196/#post-495544

Any solution not based on FileProvider is wrong.

It seems like you haven't put the file in the correct place.

Are you running this example as-is: https://www.b4x.com/android/forum/threads/share-txt-files.73166/#post-464921 ?

Yes, just downloaded, extracted and run.
I have not change anything in the code or file directory.

Which device are you using? What is the output of Log(File.ExternalWritable) ?

I am using galaxy s8

I need to mention that when i start the app i dont get any permission request. In the service there is also no request only a declaration but no request call. Should it be like that?

Erel · Mar 11, 2018

No permission is required.

Change Service_Create of the starter service to:

B4X:

Sub Service_Create
   shared = rp.GetSafeDirDefaultExternal("shared")
   Log(shared)
   Log(File.ExternalWritable)
   File.WriteString(shared, "1.txt", "aaa")
End Sub

What is the output? Does it throw an error?

Are you using B4A Sdk Manager? Have you updated all the recommended items?

I have never used b4a sdk menager. Should i?

DonManfred · Mar 12, 2018

ilan said:

YES. The old sdkmanager does not work anymore.
Create a NEW Folder and setup a new SDK There using the B4A SDKManager. Make sure to configure the IDE to use the new one.

DonManfred · Mar 12, 2018

Follow the instructions:

2. Android SDK

Download Android SDK command line tools.
Unzip it in a folder such as C:\Android

3. B4A

Download B4A Trial Version
Open B4A.
Choose Tools > Configure Paths.
Set the path to "javac.exe" if it is empty (C:\Program Files\Java\jdk1.8.0_102\bin\javac.exe).
Click on Open Sdk Manager button.
Set the path to "sdkmanager.bat" (C:\Android\tools\bin\sdkmanager.bat) and install all recommended items.
Read and accept the licenses when asked for.
Return to B4A and set the path to "android.jar" (C:\Android\platforms\android-27\android.jar).

Thanks donmanfred i will do that but what will happen with old project? Will they still run?

DonManfred · Mar 12, 2018

They should, yes.

Ok thanks i will try it.

Is there a way to go back if i will get problems with old projects?

DonManfred · Mar 12, 2018

ilan said:

no. The old SDK does not work anymore. It is mandatory to switch.

If you have any issue: create a new thread for it. Probably it is due to an mistake in your code (adding android-supporr-v4.jar using #additionaljar for example.
