Using the JPackageInfo class is simple to retrive the version of your Android application. This class is already wrapped by Embarcadero in the following unit: Androidapi.JNI.GraphicsContentViewText {code} {$IFDEF ANDROID} var PackageManager: JPackageManager; PackageInfo: JPackageInfo; begin PackageManager := SharedActivityContext.getPackageManager; PackageInfo := PackageManager.getPackageInfo (SharedActivityContext.getPackageName, 0); result := JStringToString(PackageInfo.versionName); End; {$ENDIF}
L’obiettivo era quello di connettersi a livello programmatico ad una specifica WiFi da qui è sorta l’esigenza di gestire in modo completo la classe Java WifiManager. Nei tre metodi principali riportati di seguito avremo: riconoscimento dell’IP Address assegnato alla porta wifi Elenco delle Wifi disponibili (quelle che il dispositivo riconosce) Elenco delle configurazioni WiFi salvate…

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
