I am trying to create a PDF document and then open it in an Android app. The code is based on the GitHub project https://github.com/AlessandroMartini/Delphi-Android-GeraPDF I am using Delphi in RAD Studio 11.
I have successfully worked around the permissions to allow my app to save the file that it created and am now stuck at trying to view the file I have created using Intent to allow the file to be opened in another app to view it.
In my main form I have the following:
Intent := TJIntent.Create;
Intent.setAction(TJIntent.JavaClass.ACTION_VIEW);
{ based on solution from https://stackoverflow.com/questions/54535225/android-os-fileuriexposedexception-filename-exposed-beyond-app-through-intent }
var lfile := TJFile.JavaClass.init(FileNameJ);
Intent.setFlags(TJIntent.JavaClass.FLAG_ACTIVITY_NO_HISTORY or
TJIntent.JavaClass.FLAG_ACTIVITY_CLEAR_TOP);
var LAuthority := TAndroidHelper.Context.getApplicationContext.getPackageName.concat(
StringToJString('.fileprovider'));
var Data := TJContent_FileProvider.JavaClass.getUriForFile(TAndroidHelper.Context,
LAuthority,
lFile);
Intent.setDataAndType(Data, StringToJString('application/pdf'));
TAndroidHelper.Activity.StartActivity(Intent);
This seems to be good so far.
My AndroidManifest.template.xml file is this, with the <provider></provider> section added to the default code:
<?xml version="1.0" encoding="utf-8"?>

My fileprovider.xml file contains the following:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<cache-path name="external_files" path="."/>
</paths>
I am aware that the path value is not what I should be using, that I can fix later.
The problem comes after I have built this and try run it.
AndroidManifest.template.xml is in the root folder of my project source.
I have tried placing fileprovider.xml in the project root, ./res, ./xml and ./res/xml folders but I am getting a PAClient error indicating that fileprovider.xml can not be found.
[PAClient Error] Error: E2312 Unable to execute '"C:\Users\Public\Documents\Embarcadero\Studio\22.0\CatalogRepository\AndroidSDK-2525-22.0.42600.6491\build-tools\30.0.3\Aapt.exe" package -f -M "C:\Projects\Rad\JavaTest1\Android\Debug\TestPermissions\AndroidManifest.xml" -F "C:\Projects\Rad\JavaTest1\Android\Debug\TestPermissions\bin\TestPermissions-unaligned.apk" -I "C:\Users\Public\Documents\Embarcadero\Studio\22.0\CatalogRepository\AndroidSDK-2525-22.0.42600.6491\platforms\android-30\android.jar" -S "C:\Projects\Rad\JavaTest1\Android\Debug\TestPermissions\res" -A "C:\Projects\Rad\JavaTest1\Android\Debug\TestPermissions\assets" "C:\Projects\Rad\JavaTest1\Android\Debug\TestPermissions\library" "C:\Projects\Rad\JavaTest1\Android\Debug\TestPermissions\classes"' (Error 1)
[PAClient Error] Error: E2312 C:\Projects\Rad\JavaTest1\Android\Debug\TestPermissions\AndroidManifest.xml:38: error: Error: No resource found that matches the given name (at 'resource' with value '@xml/fileprovider').
Any ideas why fileprovider.xml is not found?
