Android :: Open Pdf From My App Using Built In Pdf Viewer
May 26, 2010
I want to be able to open a pdf file in my app using the android's built in pdf viewer app, but i dont know how to start other apps. I'm sure i have to call start activity, i just dont know how to identify the app im opening and how to pass the file to that specific app.I just learned that the pdf viewer i have on my phone is actually made by HTC and that Adobe just barely released their android pdf viewer (which is great). So the new question is this: how do i verify that the user has installed adobe's viewer, and then how do i open the file in that app from my app?

Just wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.

Ok I have been trying to figure this out for a while. I have an application that needs to read images from a folder created by the application on the sdcard. I have no idea what the names of the files are because the user specifies the names of the files. I need to read the images from the folder and make something like the default image viewer, where you can share them delete them and things like that. Im thinking read them into a grid view first but 1) cant figure out how to dynamically read them from a folder 2) how would I implement the image options like the default viewer? If there was a way to open the default viewer on a certain folder that would help.
Anyways any input would be amazing been working on it for a while.

All of the tickets are electronic tickets (pdf) saved in my gmail, and I thought I would be able to open up the files and just let them scan my phone. Yet when I tried to open the file, it pulled up the PDF viewer app and then told me it wasn't able to open it. Why is this? I also just tried saving the attachment to my sd card from the gmail app and open it from there, but I couldn't figure out how to save an attachment from an email to my phone. Any help here would be great.

I have done many of reverse engineering for other electronics in the past, Since Im new to android I was wondering before even wasting my time if is possible to port, or built a rom from sources or a phone thatis NOT External SD built in to a phone that it have the external sd built in.
Making it short can I try to reverse engineer the android code from a Nexus 5 (no ext_sd) to other device that have ext_sd built in?
If is possible where should I be looking to start trying making some development on this as I haven't done nothing close quite.

I need a good pdf viewer, on the market there are two (> 4 stars) cheap options (AFAIK)BeamReader (1.99)RepliGo (1.99). I only find comparison between Beamreader and docs2go(9.99) and many of you point that d2g can do more that beamreader, but I don't need to read office files (I do use open office and D2g doesn't seem to be able to read pdf). I didn't find a direct comparison between the first two options so which is better Beamreader or Repligo and why?

I'm a writer and I tend to write in the .rtf (Rich Text File) format. I have Dropbox and I'd like to be able to pull up my .rtf files on the phone from Dropbox to go over them. The trouble is, I can't find a good .rtf editor or viewer program to do so. I don't really need the editing function, just a viewer will do. I have Astro as well. Phone is an Evo with Sprint.

I have a ListActivity that uses a CursorAdapter to fill the rows in the view. I wrote a database helper class that gives me back results for common queries I make for my app, and it uses an SQLiteOpenHelper implementation I wrote to open the database. I use the open helper to open the database and get a cursor to pass to my CursorAdapter.
Here's a code snippet:
CODE:...................
The problem I'm having, that I didn't have before I implemented the open helper (before I just opened the database directly without a helper), is when I click on an item, which takes me to another activity, and then go back to this activity. When it initializes everything is fine, and my list is populated fine, but when I go back from the activity that follows, the list is empty and in the LogCat I see "Invalid statement in fillWindow()".
It appears from a few post I've seen that the reason is, when I requery the cursor, the database is closed. But I'm not closing it! I'm scratching my head on this one.

I copied a PDF to the 'My Documents' folder of my 8gig memory card, opened up PDF Viewer and it responded 'No files were found on your phone'. So this begs the question, how do I load up a bunch of PDF's so I can view them on the phone?

When I get my Incredible, I have an urgent need for a PDF reader that actually works well. It does not have to be free. My file size ranges up to 11mb. If I can't find one for Android, then I may have to carry two devices. I want to replace my Ipod Touch which has PDF apps with my Incredible. Can't wait for the 29th.

Is there a trick to getting the Hierarchy Viewer to work in landscape orientation, or is it completely broken? In Pixel Perfect View it shows my screen sideways (i.e. in portrait aspect ratio), but when I click on the views in the explorer area it outlines the wrong areas of the screen. It looks like the outlining assumes the display is in landscape orientation, so it outlines where the views would be if it were oriented correctly. Obviously fixing the display would be the best solution, but barring that I'm OK tilting my head if only the outlining would agree with the display. Anyone know a way around this?

Just got around to trying the built in photo viewer in Droid accessed through gallery, Just tried free app 'picture viewer' and it's better, but still not great. Going to keep looking. What I am looking for is to flick through photos, which picture viewer does, but also being able to pan around pic if zoomed in. Also automatic search of SD card for folders with pictures.
