Example text

In that case, it may be a good idea to actively suppress a warning for a specific part of the code to indicate that things are okay, despite what lint thinks. Suppressing lint warnings can be done for both Java and XML source files. For Java, you use the annotation @ SuppressLint with the warning you want to suppress as an argument, as shown in Figure 1-6. In XML files, you include the lint namespace and add tools:ignore=”WarningName” (where WarningName is the warning you want to suppress; see Figure 1-7) to the part where you want to suppress the warning.

In XML files, you include the lint namespace and add tools:ignore=”WarningName” (where WarningName is the warning you want to suppress; see Figure 1-7) to the part where you want to suppress the warning. Remember that lint warnings are there for a purpose. They indicate areas that are potential bugs, so always carefully consider whether you really want to suppress the warning. It’s often better to leave the warning in place rather than remove it, as a reminder that it should be dealt with later.

However, even with carefully written unit tests, it’s hard to cover all possible situations that might occur in the code, which is why it’s important to complement unit testing with other methods@mdfor instance, static code analysis. Fortunately, Google has added such a tool, called lint, to the Android SDK. The lint tool performs checks on your project’s source files, both XML and Java, and searches for missing elements, poorly structured code, unused variables, and more. In your IDE, the results appear as highlighted areas (see Figure 1-5) indicating that something needs to be fixed.
