Hi all ! Since BT version 4, the pdf plugin lost something on Android. If the option "download from URL" is chosen, the file does seem to get downloaded, but the Open button does not open it. If the option of a local file is chose, and making sure the pdf file is located in the Doc folder, there is a pop-up message stating that the file is not found, and the open button does not open anything. So I'm guessing there is a problem with the Open function ? Thanks to anyone who can help ! Good day Nico

I now actually think it doesn't save in the cache... But I don't know how to check and correct that. ?

In either android or iOS, there is a 'does cached file exist' method that I use, and have it write to the logcat. For android, something like this: string cachedFileName = "mydesiredfile.txt" if(BT_fileManager.doesCachedFileExist(cachedFileName)){ BT_debugger.showIt(cachedFileName + " exists"); }else{ BT_debugger.showIt(cachedFileName + " does not exist"); } Something like that should write to the logcat and let you know if it's there. Hope this helps! Cheers! -- Smug

Hi Smug, you were my saver 2 years ago and here you are again ! :) While incorporating your lines, I actually found an original check for whether the file is in cache or not. In case the file is not in cache, it writes in the logcat ":handleEmailDocumentButton Cannot email document, document not in the cache?", and it is the case indeed. So the file is not saved in the cache. ***If I open a pdf that is stored in the Assets/Doc, I get this : 05-24 09:30:09.016 17159-17159/com.motorcyclevocabularylight W/ZZ: BT_fileManager:copyAssetToCache: MotoVocLight-Engine.pdf 05-24 09:30:09.017 17159-17159/com.motorcyclevocabularylight W/ZZ: BT_fileManager:copyAssetToCache :EXCEPTION java.lang.SecurityException: MODE_WORLD_READABLE no longer supported BT_fileManager:deleteFile MotoVocLight-Engine.pdf So somehow it is saved but then deleted ? ***If i download the pdf from URL, it does seem to be downloaded : 05-24 09:48:49.362 17159-17811/com.motorcyclevocabularylight I/ZZ_: finished downloading file finished downloading file ***But when I click on Open : 05-24 09:50:05.665 17159-17159/com.motorcyclevocabularylight W/ZZ: BT_screen_pdfDoc:openDocInCache.

HOW DO I CHANGE THIS VALUE ? Thank you !!! Nico

Hmm... Now it's starting to get a bit involved, lol! Which 'intent' are you compiling for? According to this: https://inthecheesefactory.com/blog/how-to-share-access-to-file-with-fileprovider-on-android-nougat/en anything beyond API 24 cannot use the 'file://' method to open a file. Things may need an update. Cheers! -- Smug

Smug, get a chance to try to update this old Android PDF doodad? Read that article above, looks easy enough. Easy enough for someone other than myself. Lol. Tim

Smug thank you very much for your input. I was away and didn't have a chance to say so earlier. As soon as I can I get my head back into it. Cheers Nico

Just a short update. I just run into the same problem and tried the following: I substituted the following part in function "openDocInCacheWithMimeType" in "BT_viewUtilities.java" ************************************ //make sure it copied... if(BT_fileManager.doesCachedFileExist(fileName)){ PackageManager pm = SyNA_appDelegate.getApplication().getPackageManager(); ApplicationInfo appInfo = pm.getApplicationInfo(SyNA_appDelegate.getApplication().getPackageName(), 0); File theFile = new File(appInfo.dataDir + "/files/" + fileName); ************************************ with ************************************ BT_fileManager.copyFileFromCacheToSDCard(fileName); File theFile = new File(SyNA_appDelegate.getApplication().getExternalCacheDir(), fileName); //make sure file exists... if(theFile.exists()){ ************************************ It simply copies the file from the app-specific cache to external memory that allows other apps to open the document. In this way all my "the file is corrupted and can not be opened" error messages went away and I could open the documents in Word, Google drive, EbookDroid,... Happy coding Thomas

Hi Thomas, Thanks for your input on this matter. I have finally come to try it and I get and error when compiling stating in your lines : Cannot Resolve symbol 'SyNA_appDelegate' ? Cheers Nico
