Wie kann ich eine PDF Datei vom lokalen Ordner mit einer externen App öffnen?

[JP1991]

Hallo zusammen,

ich bräuchte Hilfe bei meiner App. Ich habe die benötigte pdf Datei mittels ASDDownloader Extension heruntergeladen. Diese befindet sich im Download Ordner. Nun möchte ich diese Datei mittels externer Reader-App öffnen können.
Unter Android 10 ging es bei mir noch mittels Starter, aber hier weiß ich nicht weiter.

Wichtig ist, die Datei extern zu öffnen, da ich hier die Suchfunktion benötige.

Danke für eure Hilfe

Hello Taifun,

thx for your fast reply.

I use that extension.

[FREE] ASD Downloader Extension - Download and manage files in ASD

Updated Version 4 Added properties to set notification title and description, if system download notification is being set to visible. Added property to set Custom Download Path to set custom path other than ASD, that means now this extension is not limited to ASD only, it can download files in specified path. [image] [IMG_20240323_183122] Added a new function: FilesListFromAssets to get list of files from app assets directory. [image]

and with custom Download path i download it to the /Download folder.

It's working so far, but how can i open it now with a button in app?

Thats right, but its on internal storage. In the example it says it only workes with sdcard.

Is there any way, I can use the file in internal storage/Download?

Next Screenshots i switch to english. - sry.

And sorry for my bad english.

I try to make a part of the app, that first of all download a pdf file from internet.
Thats working so far. - it is stored in internal storage /Download.

But i can't find any way to open that saved file with external app.
I have the file, the path ... but i do not understand how to open it.

In older android versions it had worked.
But now i have Android 14 and i can't open the file. whether i have a file on internal storage or external.

Would really be great if someone can help me here.

Thats right, but its on internal storage. In the example it says it only workes with sdcard.

That's corect, we are talking about the emulated sdcard, not external (removable) sdcard ... thanks to Google and the restrictions to keep us "safe"...

writing to the external (removable) SDcard is no longer possible since Android 19 (KitKat ).

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
