To find a file in the Android Shell “ADB” you can use this command:
|
1 |
# busybox find "filetosearch" |
you can do the same with
|
1 |
# ls -R | grep "filetosearch" |
but you can’t see the directory where is the file
DKLang è un package per Delphi relativo alla gestione dell’internazionalizzazione delle applicazioni. E’ composto da un insieme di componenti, classi e tools veramente ridotto ma efficace, il tool è open source e compatibile con tutte le piattaforme di sviluppo di Delphi (Windows,MacOSX,iOS,Android e Linux) sia per Firemonkey che VCL. Le versioni del tool sono scaricabile…

Changing the text property of a tree item in Firemonkey is really simple, you only need to do this:
|
1 2 3 4 5 6 7 |
tiC := TTreeViewItem.Create(<your TreeView Object>); tiC.Text := 'BLA BLA'; tiC.StyledSettings := []; tiC.TextSettings.FontColor := TAlphaColorRec.Blue; tiC.Parent := ParentItem; tiC.TagString := <some data if you need>; tiC.Tag := <some id if you need>; |
The popular development platform “Rad Studio” Embarcadero reaches the 10.2 version of Linux reintroduction as a supported platform. At the moment the only compilation target for linux x86 64bit, which to me is very tight, because it is a native environment the target that I would have loved to ARM’s 32/64-bit fast to develop modules…
