Please refer to the updated readme: https://github.com/DelphiWorlds/Kastri/tree/master/Demos/Biometric#readme

You mean Delphi 11.1? Delphi 11.2 is yet to be released. I just checked on my Android 9 device - it appears there is an issue. I'll repost again after I've found a solution. Because it needs to be added to Android 32-bit only. It will apply to both.

There are no such instructions in the readme for that demo project. Doing so is what has caused your problem, as it has re-enabled the jars that need to be disabled. Please re-load the original version of the demo project (BiometricD11)

Execute external program/command and capture output
Dave Nottage replied to softtouch's topic in Cross-platform
I don't have any concrete examples as yet, however there is this: https://github.com/DelphiWorlds/Kastri/blob/master/Core/DW.RunProcess.Mac.pas -
About 4 weeks ago I submitted an update to an app for review on Google Play Store and it took 4 days. After 2 days I queried the delay (which was unusual because the previous updates were available within hours) and they replied that such delays occur from time to time.

Exactly. There should be an option in the Version Info to override what the IDE defaults to (currently 30). I've now added this report to the Quality Portal: https://quality.embarcadero.com/browse/RSP-38976

Replicating a routine that uses OpenSSL to use another library
Dave Nottage posted a topic in RTL and Delphi Object Pascal
I'd like to be able to remove a dependency on OpenSSL, which is being used in this routine (original context hereπ class function TgoSSLHelper.Sign_RSASHA256(const AData: TBytes; const APrivateKey: TBytes; out ASignature: TBytes): Boolean; var BIOPrivateKey: PBIO; PrivateKey: PEVP_PKEY; Ctx: PEVP_MD_CTX; SHA256: PEVP_MD; Size: Cardinal; begin BIOPrivateKey := BIO_new_mem_buf(@APrivateKey[0], Length(APrivateKey)); PrivateKey := PEM_read_bio_PrivateKey(BIOPrivateKey, nil, nil, nil); Ctx := EVP_MD_CTX_create; try SHA256 := EVP_sha256; if (EVP_DigestSignInit(Ctx, nil, SHA256, nil, PrivateKey) > 0) and (EVP_DigestUpdate(Ctx, @AData[0], Length(AData)) > 0) and (EVP_DigestSignFinal(Ctx, nil, Size) > 0) then begin SetLength(ASignature, Size); Result := EVP_DigestSignFinal(Ctx, @ASignature[0], Size) > 0; end else Result := False; finally EVP_MD_CTX_destroy(Ctx); end; end; I'm a bit green when it comes to cryptography routines, so I'm not exactly sure what it is doing, and the OpenSSL docs are quite verbose, however my goal is to be able to use another library like LockBox, or DCPCrypt (if it can handle it) so as to remove the dependency on OpenSSL. Can someone help replicate it using LockBox3 or perhaps some other (non-commercial) library, or at least point to which classes should be used? -
Replicating a routine that uses OpenSSL to use another library
Dave Nottage replied to Dave Nottage's topic in RTL and Delphi Object Pascal
Thanks, however I'm after something that is cross-platform. -
The message would be that you need to target API level 31 or more. As pcplayer99 inferred, you will need to modify your AndroidManifest.template.xml, by replacing %targetSdkVersion% with the value: 31. You will also need to add an android:exported="true" attribute to the application node in the same file, so that it looks like this: <activity android:name="com.embarcadero.firemonkey.FMXNativeActivity" android:label="%activityLabel%" android:configChanges="orientation|keyboard|keyboardHidden|screenSize" android:exported="true" android:launchMode="singleTask"> If you changed your SDK settings in Delphi SDK Manager to use API level 31, you should change them back to API level 30 unless you want to be stuck with other problems in the manifest (when compiling the app)

Is it true that using FMX units will cause android apps to fail?
Dave Nottage replied to KMarb's topic in FMX
You cannot use FMX.xxx units in an Android service built with Delphi. See: https://quality.embarcadero.com/browse/RSP-17857 -
Your Android device does not support the selected target platform architecture
Dave Nottage replied to alogrep's topic in FMX
Some devices have 64-bit CPUs, but have Android 32-bit running on them. Easiest way to find out if this is the case for you is to download an app like this. On the CPU page it reports whether the device is running in 32-bit mode. -
Can Delphi 11 IDE handle debugging two Android phones at the same time?
Dave Nottage replied to Al T's topic in Delphi IDE and APIs
Fair enough - I'd first try 2 instances of Delphi as SwiftExpat has suggested (have you tried this?), otherwise if that's too problematic: the second instance running in a Virtual Machine. -

More to it than that: Updating the label (or anything UI related) needs to happen in the main thread - see Rollo62's answer- 5 replies

Multiplatform Hello World error [PAClient Error] Error: E7688

Looks like you may be using a project created with an older version of Delphi. Please refer to: https://github.com/DelphiWorlds/HowTo/tree/main/Solutions/AndroidLibraries -
[Solved](Delphi 11) (Android 12) 32-bit Debug Segment Fault 11 (TFile.Copy?)
Dave Nottage replied to Al T's topic in FMX
I'd expect that behaviour if CopyData was running in a separate thread. It would not normally be an issue, otherwise.- 5 replies

Dave Nottage replied to Al T's topic in Delphi IDE and APIs
I doubt it is possible with one instance of Delphi. Might be better to explain why you need it - there may be an alternative. -
Keeping edit field in view when on-screen keyboard appears
Dave Nottage replied to KMarb's topic in FMX
There's this (outdated) article. The demo has moved to here, and it sorely needs another revisit π -
Your repo violates copyright, by including a near copy of System.Zip (apparently from an earlier version of Delphi)

Is there any reason why you can't download to an app-specific folder? There are a number of changes in Android 11 that make it difficult to manage storage in shared folders: https://developer.android.com/about/versions/11/privacy/storage Which would explain why you are having issues. If you're logging from an app, the easiest way is to use Log.d from the FMX.Types unit. You can view the log messages using a logcat viewer - I have one called Device Lens. In Delphi, there's a permission in the Uses Permissions > Signature section of the Project Options called "Request install packages". Even with that checked, the OS might request approval from the user.

This is a complete routine that should work: procedure OpenApplication(const AFileName: string); var LMimeType: JString; LIntent: JIntent; begin LMimeType := TJMimeTypeMap.JavaClass.getSingleton.getMimeTypeFromExtension(StringToJString('apk')); LIntent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW); LIntent.setDataAndType(JFileToJURI(TJFile.JavaClass.init(StringToJString(AFileName))), LMimeType); LIntent.setFlags(TJIntent.JavaClass.FLAG_GRANT_READ_URI_PERMISSION); TAndroidHelper.Activity.startActivityForResult(LIntent, 999); // 999 is just a random value - it won't matter what it is end; Note the extra line regarding FLAG_GRANT_READ_URI_PERMISSION.

Sorry.. missed a step. Delete AndroidManifest.template.xml in the project folder. The IDE will recreate this. If you have made any customisations to it, you will need to ensure you reinstate those after it is recreated.
-
This should be: Intent.setDataAndType(JFileToJURI(F)), StringToJString('application/vnd.android.package-archive')); JFileToJURI uses the FileProvider class to create the correct URI You won't need to do that if you check the Secure File Sharing option in the Entitlements List in the Project Options. This also creates and deploys the required xml file.

Delphi 10.4.2 won't open a specific .PAS file
Dave Nottage replied to MJBComp's topic in Delphi IDE and APIs
How big is the file? It might have some odd characters in it that the IDE cannot handle? Or maybe some peculiar structure? For the characters problem: try loading it in Notepad, make a minor change, then save it, then load it in Delphi again.
