Android Question B4A 5.2

[DT1111]

Hi Erel

I have managed to compile my program developed in older B4A with the latest B4A 5.2 without any problem. That is really good.

Does that mean the app is now is going to run OK under Android 5.0 and beyond. Or is there something else I need to do like in the manifest etc. I just want to make sure.

Plus the designer has a message that says an update is recommended in order to run more efficient and I can't remember what the update is.

that would be a .NET update (4.5.2 or something?)

Go over this short tutorial: https://www.b4x.com/android/forum/threads/45967/#content

You can find the link to .Net 4.5.2 here: https://www.b4x.com/b4a.html

Thanks.

If incorporating the line below in the manifest makes the app Android L compliant, then that is easy enough. But my only gripe is, it turns background of most controls into grey.

I have preference for the old look ie white background for textboxes, dropdown boxes, list etc. Is there something that I can do to preserve the old look and still make the app Lollipop compliant.

SetApplicationAttribute(android:theme, "@android:style/Theme.Holo.Light")

I also notice that the app runs a lot slower especially when reading large data from a file when I use

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14"/>

Prior to that I was using just. What could be the cause?

<uses-sdk android:minSdkVersion="4" />

I didn't like the look on new tablets either and I added this to my manifest to correct most of it.

android:theme="@android:style/Theme"

The theme doesn't have any effect on the performance. Click on Ctrl + P to clean the project. It will force the debugger to make a full deployment and it will be faster.

Thanks Sorex and Erel.

I have tried as suggested and it definitely brought back the old look. Great but does it still make it Lollipop friendly?

android:theme="@android:style/Theme"

Erel

I did Ctrl+P and used the following. It is still slow.

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14"/>

 

[Erel]

So it is slow for other reasons. The theme used doesn't effect the performance. Make sure to test performance in release mode.

Android is backwards compatible so it should work with Android 5+ as well.

Hi Erel

I have tested the performance in Release mode (previously was tested in Release Obfuscator mode)

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14"/>

with and without theme and it is also slow.

Android is backwards compatible so it should work with Android 5+ as well.

If I understand your statement, android:theme="@android:style/Theme" will enable the app to work in Android 5+. Is that correct?

 

[Erel]

As I said the performance is not related to the theme. If you want to further discuss the performance then you should start a new thread and explain what your app is doing and which part is slow.

If I understand your statement, android:theme="@android:style/Theme" will enable the app to work in Android 5+. Is that correct?

Yes. Though it is safer to use Android 4 theme.

 

[DT1111]

Would the following cause an issue in Android 5+

#Region  Activity Attributes
    #FullScreen: True
    #IncludeTitle: False
#End Region

 

[Erel]

No.
