Change Application name and launcher icon runtime.

Changing an application name and application icon from the application.

For that we need to use the <activity-alias>. This tag will be in manifest inside <application> tag.

An alias for an activity, named by the targetActivity attribute. The target must be in the same application as the alias and it must be declared before the alias in the manifest.

The alias presents the target activity as a independent entity. It can have its own set of intent filters, and they, rather than the intent filters on the target activity itself, determine which intents can activate the target through the alias and how the system treats the alias. For example, the intent filters on the alias may specify the “android.intent.action.MAIN” and “android.intent.category.LAUNCHER” flags, causing it to be represented in the application launcher, even though none of the filters on the target activity itself set these flags.

With the exception of targetActivity, <activity-alias> attributes are a subset of <activity> attributes. For attributes in the subset, none of the values set for the target carry over to the alias. However, for attributes not in the subset, the values set for the target activity also apply to the alias.

Secure Web-service Url in Android

This is serious problem that every one facing . How to secure Web-service URL if someone decompile the application.

Now a Days there are lots of tool that decompile the apk file and give possible java code. In code we have our Web-service url . Now that person have that url and get to know some important thing that we don’t want to disclose.

Even Using proguard it not Convert String resource to any secure resource.

So I research to that and have one idea that will help to secure our web-services.for that You will require only a single URL that call setup-url will setup all the stuff you want. I divide it in some steps.

Step 1 : Create Explicit Sqlite Database and insert your setup-url in any table and store it in asset folder.

Step 2 : At the Time of Execution store it in your data/data/your package/databases Location.

Step 3 : Now With Your java class File select that url from table.

Step 4 : Now while executing this web-service Pass one POST parameter as Token with it, Now at Web-service it will check first is the call is valid (Means from application) or Not. If yes then application will access the Url as response and then store it locally. If no then It will ask for token or redirect to the forbidden page.

Hope it will help to secure.

All other suggestion are welcome.
