Share My Creation Hubble Images

With Basic4android, Erel and his company have developed an invaluable environment for Android programmers eliminating need for learning Eclipse and Java. During two days of getting familiar with the concept, I realized the tremendous work.

Please allow me to share my first attempt, an app which loads a dozen Hubble images in a ListView. Upon tap on a thumbnail, a larger image will be displayed. Tap on the menu to download an ever larger image in the
web browser where you can resize and pan at will. Use WiFi to escape 3G packet fees. The app demonstrates the use of a ListView, ImageView and dual-Activity screens.

The source is included. Please feel free to comment if you have any suggestions regarding code optimization.

My Phone is a Sharp IS03 with a 640 x 960 pixels screen, obviously not to the Android standard. Hope it shows correct on your device anyway.

The next step is to swap portrait/landscape modes as the phone is turned around. Let me know if you have done it already.

Cheers
Robert

Thank you, and it is great to hear from you again.

It seems like there are some files missing (exit.png at least).

 

[alfcen]

Geez, you are fast.
Sorry, I used the Export function without loading the images in the designer.
Please try again.

 

[Erel]

Looks good now. The fonts are a bit too small. It may be related to a previous bug in the Core library related to VGA devices: http://www.b4x.com/forum/additional...pdates/6864-core-library-updated-v1-05-a.html

 

[alfcen]

Core Lib updated and font sizes doubled in the source. Looks well balanced.

ListView1.TwoLinesAndBitmap.Label.TextSize = 20
ListView1.TwoLinesAndBitmap.SecondLabel.TextSize = 16

How does that look on your device?

 

[Erel]

Good:

 

[alfcen]

Exactly as it looks on mine. That's what I call team work:icon_clap: Thanks a lot, Erel.

I have an Archos 70-250G 7" tablet with 800x480. When I try to compile and run the app onto the A70, it causes it to reboot, then it does a time-out.

 

[agraham]

It works fine on my 480 x 800 scale = 1.5 Orange San Francisco phone and on my cheap chinese 7" Eken M001 480 x 800 scale = 1 tablet.

Run it from the IDE with the device connected and look at the unfiltered LogCat output and you may see the details of an exception that will tell you where the problem is occurring.

 

[alfcen]

Thanks, Andrew, for your assistance.
The problem could be native to the tablet. If not, i'd be grateful for Log() data.

Attached, please find an update:

1. Supports landscape mode
2. Views scaled dynamically to accommodate most screen dimensions (though I can't test it)
3. Large images can be viewed, panned and sized online in Erel's superb webview
4. BGM (*.mp3 files only) can be selected and played if located in the SD root

The app is demo work leaving much room for optimization. If you wish to add more Hubble images I recommend to employ an SQLite database.

Please use or abuse at your own risk.

Same deal. My A70 reboots while the app is being installed on it (doing a compile-run to it) then after another minute or so, I get a message that it has timed out.

Nothing shows up in the LogCat tab (Filter unchecked). Would the LogCat have anything if the app never got installed?

 

[agraham]

If it hasn't installed before, or been manually uninstalled, you should see this in LogCat.

D/PackageParser( 1179* 1225): Scanning package: /data/app/vmdl38062.tmp
I/PackageManager( 1179* 1225): /data/app/vmdl38062.tmp changed; unpacking

D/PackageManager( 1179* 1225): New package installed in /data/app/requio.com_nz_177_jp.apk

 

[nfordbscndrd]

Well, I don't know what I'm doing wrong, but I double-click the Main.b4a file to open it in B4A, then I press F5 to compile it to the A70.

It gets to "Installing file to device." and after 30 seconds or so, the A70 reboots. Before it finished rebooting, B4A says "Process is running longer than expected. Do you want to cancel it?"

I say No and it keeps trying to install it, but finally says:
"Process timed out.
Restarting ADB Server may solve this problem.
Tools - Restart ADB server. Device serial: A70-579C0001-9FF8000-015DB7D4
-???????"

I click "Close", click on LogCat tab, uncheck Filter, and there is nothing showing in the LogCat.

All the stuff you listed starting with "Scanning package" would not appear if the package never got installed to the A70, right?

 

[agraham]

I click "Close", click on LogCat tab, uncheck Filter, and there is nothing showing in the LogCat.?

You need to have unchecked Filter and Connected LogCat before you compile. Press Clear as you start to compile and possibly yank out the USB connection as soon as it reboots to keep the LogCat you have captured.

 

[agraham]

My LogCat viewer is more flexible that the one in the IDE for non-Basic4android LogCat messages.

 

[nfordbscndrd]

I clicked Clear and immediately hit F5 to compile. When it rebooted, I pulled the plug. I got what looks like a couple of hundred lines of Logs. From what I can tell, this is a relevant part:

 

[alfcen]

Not sure how to decypher the log, but the package name is

requio.com_nz_177_jp.hubble

not

requio.com_nz_177_jp.hubble-1

Further, "unmount attempt failed"... is the tablet attempting to install to SD?

 

[agraham]

I think the real problem is "does not include classes.dex". It looks like the same problem as in this thread http://www.b4x.com/forum/basic4android-updates-questions/7103-problem-ide-sending-adk-phone.html. See post#21. I don't know what the resolution to the problem was as the user hasn't reposted so I assume he got it running somehow.

Works fine on my Galaxy 550 (320*240). Thx
