Android Question APK not working on android 9.0 working on 8.1.0

[Juzer Hussain]

Hi Friends,

As per the requirements of google to change api level and targetSDKversion I changed my manifest file as below

<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" maxSdkVersion="26" />

After doing this change app is working in older android version upto 8.1.0 but its not working in later versions.

Is the manifest file ok, Do I need to do something else also.

Pls suggest.

Thanks
Juzer Hussain

Where is the error you get?

 

[Juzer Hussain]

Don't get any error.
On Login button click it runs a job to connect to server.
The job is failing.The job should succeed.

 

[DonManfred]

Check the unfiltered log. If the job finishes unsuccessfully then there must be an error.

Upload a small project which shows the issue.

 

[Juzer Hussain]

Job should fail in other mobiles also.
If there is error. Its not failing in all versions.

 

[DonManfred]

Are you calling http (not https) urls?
If so then you need adapt your manifest because of plaintext access.

See android.jar / targetSdkVersion / minSdkVersion

 

[Juzer Hussain]

Yes i am using http site.
The link says add
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
to AndroidManifest.xml
I added in Manifest file.
Do i need to do something else also?

 

[DonManfred]

yes. Check the tutorial again

I read it but don't see anything else.
Can u pls point it.

 

[DonManfred]

I read it but don't see anything else.
Can u pls point it.

OMG

There are 3 SDK 28 Items. Only one of them points to "non-https".

Hmm, which one could it be?

 

[Juzer Hussain]

SORRY. CreateResourceFromFile(Macro, Core.NetworkClearText) to be added in manifest.
I am using B4A 8.5 will that be ok.

 

[DonManfred]

i dont know. the macro is added to B4A 9+

You can try to add this to your manifest

SetApplicationAttribute(android:networkSecurityConfig, @xml/network_security_config)
CreateResource(xml, network_security_config.xml,
<network-security-config>
<base-config cleartextTrafficPermitted="true">
    <trust-anchors>
        <certificates src="system" />
    </trust-anchors>
</base-config>
</network-security-config>

Thank You, DonManfred I will recompile and check with client in a day or two if it works.
I feel it should work.
