我想打开在我的应用程序中本地分配的PDF(仅适用于ANDROID,但我完全没有得到。)>
我已经尝试过此链接:Getting exception while opening PDF file for Android 26 using Firemonkey/Delphi,但在Delphi RIO中不起作用。
所以我一直在寻找并获得以下代码:
procedure TF_NovaART.PRO_MapeaClick(Sender: TObject); var fName : String; LIntent: JIntent; LAuthority: JString; LUri: Jnet_Uri; begin fName := TPath.GetDocumentsPath + PathDelim + 'PRO_Topo.pdf'; {$IFDEF ANDROID} LAuthority := StringToJString(JStringToString(TAndroidHelper.Context.getApplicationContext.getPackageName) + '.fileprovider'); LUri := TJFileProvider.JavaClass.getUriForFile(TAndroidHelper.Context, LAuthority, TJFile.JavaClass.init(StringToJString(fName))); LIntent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW); LIntent.setDataAndType(LUri, StringToJString('application/pdf')); LIntent.setFlags(TJIntent.JavaClass.FLAG_GRANT_READ_URI_PERMISSION); TAndroidHelper.Activity.startActivity(LIntent); {$ENDIF} end;
在此链接上找到哪个:Getting exception while opening PDF file for Android 26 using Firemonkey/Delphi
我做的与写的完全一样,但是返回了以下错误:
java; lang; NullPointerException:尝试调用虚拟方法'android.content.res.XmlResourceParser android.content.pm.PackageItemInfo.loadXmlMetaData(android.content.pm.PackageManager,java.lang; String)'引用空对象
现在正在提供:
java.kabg.illegalArgumentExcpetion:无法找到配置的根包含/data/data/com.embarcadero.ART_Dinamica/files/PRO_Topo.pdf。
PS:我将我的pdf(PRO_Topo.pdf)放入部署中,而远程补丁为“。\ assets \ internal”
我认为我需要放入“ AndroidManifest”,但我已经对其进行了研究,不确定如何设置。 (此错误已使我困扰了一个多月。我跳过了这部分代码来执行其他操作,但是由于这个原因,我再次无法继续执行此操作)
我从文件提供者驱动器获得的GIT链接是这样的:https://github.com/DelphiWorlds/KastriFree/blob/master/API/DW.Androidapi.JNI.FileProvider.pas
如果有人可以帮助我,我将非常感激。
下面我将离开我的AndroidManifest.template.xml

我想打开一个在我的应用程序中本地分配的PDF(仅适用于ANDROID),但我完全没有。我已经尝试过此链接:打开Android的PDF文件时出现异常...
问题归结为由Delphi生成的provider_paths.xml文件中缺少条目。为了使您的方案起作用,该文件应如下所示:
