[android-developers] Bitmap on sdcard decodestream
Easy i was playing with a little app i'm developing but i've just
found a little problem... let's explain me it...
I created a sdcard and inside it I placed some jpg files.
So my data path is something like:
/sdcard/app/img/1.jpg
/sdcard/app/img/2.jpg
/sdcard/app/img/3.jpg
/sdcard/app/img/4.jpg
[...]
/sdcard/app/img/n.jpg
Now I want to create a gallery app to show out these files, I looked
at demo srcs by android sdk, but they always use imgs from
resources...
I decided to try using Bitmapfactory.decodeFile and also
Bitmapfactory.decodestream but both seems not to work fine returning a
NullPointerException
Here you are a little snippet of my app:
Java:
for(int i=0;iimgsTokens.length;i++)
{
Log.d(+i,/sdcard/app/img/+imgsTokens[i]
+.jpg);
try
{
FileInputStream is = new FileInputStream(new
File(/sdcard/app/img/+imgsTokens[i]+.jpg));
BufferedInputStream bis = new
BufferedInputStream(is);
photos[i] = BitmapFactory.decodeStream(is);
bis.close();
is.close();
//photos[i] = BitmapFactory.decodeFile(/
sdcard/app/img/+imgsTokens[i]+.jpg);
}
catch(Exception e)
{
e.printStackTrace();
}
}
any idea how to fix?

Hi sahn0 thanks for the tip, but it still fails with a
NullPointerException...
I tried looking at f.isFile() and it returns true... so file exists...

Ok, bug filed, but I don't think it could be related to images, i've
just tested jpgs and pngs, and it fails with both of them...

[android-developers] Re: Bitmap on sdcard decodestream
yes, i've just test them using the default app and also with the dev
tools raw image viewer and both are able to show my pics :(
Guillaume, may I ask you if can kindly paste a snippet of the code you
are using to load an img from the sdcard?

Does your images work with the standard Pictures application ?

Thanks Romain, you are right!
I totally forgot to init it... and it was driving me crazy :(

The fix is simple, initialize you array photos. In the bug report you
filed, the array itself is null. The Bitmap returned by BitmapFactory
is not.

[android-developers] Re: Unable to create an URI for a local sound
I'm repling you directly here it could be useful for other ppl too... or someone could help us too... As far as I have understood atm there's no way to get android.resource:// to work property, I tested it using an inside browser in my app and it always bring me to a 404 error. Btw using the internal web browser I managed to reach at least files under assets directory using file:///android_asset/namefile.ext It works fine in loadUrl, eg. I tried to place there a .mp4 file and it returns a white screen (instead of the 404 error) so I think it is able to reach that file. I'm testing this with VideoView (because I'm managing to play a local video instead of a local sound) but it doesn't work :( It seems that both file:/// and android.resource aren't working fine with VideoView and Mplayer both atm.

[android-developers] App versioning appstore
Hi, I'm looking for information about Android app versioning, in particular with reference with the appstore system. In this very moment I'm planning to develop an app with some static contents (eg. music, background, video and pics), but within a couple of months it will be possible to upgrade these static (incapsulated in app) contents, and now I'm courious to know if I have to work on a self-update system in my app, or can I handle these new versions by appstore upgrade (eg. new versions app updates on iphone app store)? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] ViewVideo mp4 or 3gp (both local or net) problems
Hi,
I was trying to set up my app to play a video.
I tried to load it form local and net both, but no way to get it
working: I still receive a Cannot play video error.
Basically I used the same src that we are able to find in sample dir.
Here you are my media.xml
?xml version=1.0 encoding=utf-8?
AbsoluteLayout
android:id=@+id/media
android:layout_width=fill_parent
android:layout_height=fill_parent
android:background=#00
xmlns:android=http://schemas.android.com/apk/res/android;
VideoView
android:id=@+id/media_video
android:layout_width=fill_parent
android:layout_height=240px
/
Button
android:id=@+id/media_home
android:layout_width=wrap_content
android:layout_height=wrap_content
android:background=#00
android:text=Home
android:textColor=#FF
android:layout_x=10px
android:layout_y=410px
/Button
/AbsoluteLayout
And here Media.java
package com.app1;
import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.MediaController;
import android.widget.VideoView;
public class Media extends Activity {
private VideoView video;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.media);
Button bottoneHome = (Button) findViewById(R.id.media_home);
bottoneHome.setOnClickListener(mHomeListener);
video = (VideoView) findViewById(R.id.media_video);
video.setVideoURI(Uri.parse(http://www.jsharkey.org/downloads/
dailytest.3gp));
//video.setVideoURI(Uri.parse(android.resource://com.app1/ +
R.raw.v));
video.setMediaController(new MediaController(this));
video.requestFocus();
}
private OnClickListener mHomeListener = new OnClickListener()
{
public void onClick(View v)
{
finish();
}
};
}
Any idea how to get it working?
