Question about Launching apps from Web

[as4rw]

Hi, everyone, I am new to this Basic4Android. I wrote an application and use web to launch it. It works on the emulator 2.33 and Dolphine web browser but not on HTC Evo Webkit web browser [Android Version 2.35]. I am not sure why. Any help is greatly appreciated.

Manifest:

AddManifestText(
<uses-sdk android:minSdkVersion="4" />
<supports-screens android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
AddActivityText(main,
<intent-filter>
<data android:scheme="my.cameraapp.scheme" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE"/>
</intent-filter>
)

----------------------------------------
From the web page:

<a href="my.cameraapp.scheme://key1/key2")>
<asp:Label ID="lblink"
runat ="server"
Text ="Launch My Camera-my.cameraapp.scheme:"
Font-Bold ="true"
Font-Size ="18px" />

Thanks.

Try to remove the categories from the intent filter.

Still not working

Hi, Erel,

Thanks for the reply. I tried to remove both of the 'categories' entries and I also tried to remove one at a time. None of them worked.

On the emulator and Dolphin web browser the code works just fine. On the default browser [Webkit?], it does not work but it does not give an error either. It just flashes and does nothing.

Thanks.

Not sure. Check the unfiltered logs. Maybe there will be a related message.

The log

Thanks, Erel,

This is the log I got from the device but I have no clue what it says. Does this give an clue why it cannot launch the program?

I don't think that it is related. Is your web page online?

Sample Page

Thanks, Erel,

I put a test line on the front page now. Thanks for looking into it.

I've tried it with the default browser and it works correctly (tested on Android 4.1).

Check the unfiltered logs and look for a line such as this:

START {act=android.intent.action.VIEW cat=[android.intent.category.BROWSABLE] dat=mywebapps:// cmp=aaa.bbb.aaa/.main (has extras) u=0} from pid 10632

This line describes the intent that is being sent.

Thank you very much...

Erel, Thanks for helping me. I have tried and still it is not working. I think that it might be the version of OS [Android Version 2.35]. Although I tried on emulator [version 2.34], it works fine. Maybe it has something to do with HTC. Anyway, thanks a lot. Do not spend any more time on it.

Robert.

This is the cause of the problem...not sure if there is a way to fix it.
