Change string resource by flavor / debug-build

Question

Let's say we have strings_test.xml, which stores string values for testing and should be shown in a debug-release. When the apk gets build as a release version all values should be change to an empty string e.g. <string name="test_some_card_text">@string/empty</string>.

Is there a possibility to achieve this?

As always, thanks in advance.

Answer 1

As @Aditya Naik said it is possible using Flavors. Official doc says

BuildType -> Flavor -> main -> Dependencies.

This means that if a resource is declared in both the Build Type and in main, the one from Build Type will be selected.

Note that for the scope of the merging, resources of the same (type, name) but different qualifiers are handled separately.

This means that if src/main/res has

• res/layout/foo.xml

• res/layout-land/foo.xml

  and src/debug/res has

• res/layout/foo.xml
  
  Then the merged resource folder will contain the default foo.xml from src/debug/res but the landscape version from src/main/res

Yes you can do that inside your app gradle under buildTypes..

 buildTypes {
        mybuild {
                 resValue "string", "test_some_card_text", '"test"'
                 resValue "string", "other_text", '"other"'
                }
         debug {
                 resValue "string", "test_some_card_text", '"test"'
                 resValue "string", "other_text", '"other"'
              }
          }

Then access it like this.

getApplicationContext().getResources().getString(R.string.test_some_card_text);
getApplicationContext().getResources().getString(R.string.other_text);

For build you need to select that build variants and have to build it.
