I had the thought of checking for tampering with the apk by embedding a couple of checks against it's size once installed on the device.I was just a bit concerned that maybe the size would change dependent on the device (e.g. different FS format or whatever).
View 5 Replies View RelatedI've followed the steps given in the Android Developer Blog to generate a build.xml for building releases for an Android Application. I need to do a custom compiling so I have overwritten the target compile of the ant_rules_r3.xml as it is said in the generated build.xml.
<target name="compile" depends="-resource-src, -aidl, -pre-compile" ...
The script works fine and generates the apk, but the problem is that Eclipse shows an error because it cannot find targets -resource-src, -aidl and -pre-compile (which are loaded when executing the script but are not really present on the build.xml). As there are these errors I cannot work with the project in Eclipse.
How can I skip the validation of this single file in Eclipse?
Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.
I want to do this entirely in an xml layout file. When I put ImageButton xml tags inside a GridView xml body, The layout panel in eclipse is throwing an exception: UnsupportedOperationException:addView(View, LayoutParams) is not supported in AdapterView.
I want to know how to make a validation on EditText.That is ,I am having one EditText that edit text should has to accept only numaric values,If other than numaric value is typed by user then it should show some alert message "pls type the numaric value...."
Is any function is avilable to find the entered text is particular type..how to handle this situation.if possible give code snippet.
I am trying to add some text validation to an edit text field located within an alert dialog box. It prompts a user to enter in a name.
I want to add some validation so that if what they have entered is blank or null, it does not do anything apart from creating a Toast saying error.
So far I have:
code:.........
But this just closes the Alert Dialog and then displays the Toast. I want the Alert Dialog to still be on the screen.
I am trying to update Android SDK on Windows XP. For that I open Android SDK and ADV manager and try to get available updates. The HTTPS SSL error appears. Then I go to settings, uncheck the "force https...", then add new site "http://dl-ssl.google.com/android/repository/ repository.xml" (the same as default but with HTTP protocol) then again try to get available updates.
After this step I get the weird error:
XML verification failed for http://dl-ssl.google.com/android/repository/repository.xml. Error: cvc-elt.1: Cannot find the declaration of element 'sdk:sdk- repository'. Failed to fetch URL http://dl-ssl.google.com/android/repository/repository.xml, reason: Unknown

I've been trying to create a Compound Control in Android 1.5 (as described here) but haven't been able to find any good examples on how to do this using an XML file to specify a layout. Create Custom Component based on LinearLayout, declaring layout in XMLI'm fine with creating an Activity and then loading an xml file using the following in the constructor:
setContentView(R.layout.main);
However, I want to do this in subclass of LinearLayout - so I can use this compound component in other XML layouts. Something along the lines of:
public class CustomView extends LinearLayout
{ public CustomView(Context context) {
super(context);
setupView();
} public CustomView(Context context, AttributeSet attrs)
{ super(context, attrs);
setupView();
} public void setupView() {
setContentView(R.layout.custom);
// Not possible } }
What is the correct way of going about doing this?

I'm dealing with a problem you guys might not have faced earlier. I'm having a use-case in my Android application where the actual screen that I want to show to user is not stored in any layout file of my application. The layout of the of the screen is designed by server in this case, based on selection made by user on first screen.
Let me elaborate here,
1st Screen : List of check box with different biller names. (Imagine I've selected 2 billers from this screen)
2nd Screen : (The screen that server has decided how it should look like)
* Header,
* 1st Biller name (Label)
* Amount for 1st Biller TextBox
* Image (a Separator image)
* 2st Biller name (Label)
* Amount for 2st Biller TextBox.
* Here there can be a checbox/radio/another TextBox anything.
* Image (a Separator image)
* Button (to submit above form back to server)
I hope makes some sense in what I'm planning to design. The current issues I'm dealing with are as below.
1). How to draw this dynamic widgets?
2). How to fetch user Inputs from this dynamically created widgets?
