Common mistakes when working with Explicit intents?

When working with explicit intents in Android, developers often make several common mistakes. Understanding these pitfalls can help you write cleaner and more efficient code.

1. Forgetting to Declare Activities in the Manifest

Each activity that you want to start with an explicit intent must be declared in the AndroidManifest.xml file. Failing to do so will result in a runtime exception.

2. Using the Wrong Context

Make sure to use the correct context when creating your intent. Using an application context instead of an activity context can lead to unexpected behavior or exceptions.

3. Not Passing Required Extras

If the target activity expects specific data (e.g., passed in as extras), failing to include these can cause crashes or incorrect behavior.

4. Not Handling Start Activity Results Properly

If you're starting an activity for a result, ensure you correctly handle the result in your calling activity's onActivityResult method.

5. Mistakenly Using Implicit Intents

If you intend to start a specific activity, avoid using implicit intents, as this can lead to an undesired activity being opened.

Example Usage of Explicit Intent

Intent intent = new Intent(CurrentActivity.this, TargetActivity.class); intent.putExtra("key", "value"); startActivity(intent);
