Summary of Changes
Hello @PruthiviRaj27, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
I've implemented a mechanism to prevent the checkForForceUserData method from being called multiple times concurrently. This ensures that the asynchronous operation to check user data is not initiated redundantly, improving stability and resource management by avoiding potential race conditions or unnecessary processing.
Highlights
- Concurrency Control: I've introduced a new boolean flag,
isCheckingForceUserData, to manage the execution state of thecheckForForceUserDatamethod. - Preventing Redundant Calls: I've implemented a check at the beginning of
checkForForceUserDatato return early if an operation is already in progress, using theisCheckingForceUserDataflag. - State Management: I've ensured the
isCheckingForceUserDataflag is reset tofalseupon completion (both success and exception) of the asynchronousSafeAsyncTaskwithincheckForForceUserData.

Code Review
The pull request introduces a mechanism to prevent multiple concurrent calls to checkForForceUserData(). This is achieved by using a boolean flag isCheckingForceUserData. The implementation is correct in setting the flag before an asynchronous operation and resetting it upon completion, both on success and failure. My feedback focuses on improving the code's maintainability by centralizing the flag reset logic.

Code Review
This pull request adds a check to prevent opening multiple instances of EnforceDataActivity if one is already at the top of the activity stack. The implementation of the check, isEnforceDataActivityOnTop, uses a deprecated API and is susceptible to a crash. My feedback includes a suggestion to make the implementation safer and more robust, and I also recommend looking into alternatives for the deprecated API for a better long-term solution.
| public boolean isEnforceDataActivityOnTop() { | ||
| ActivityManager am = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE); | ||
| List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1); | ||
| ComponentName topActivity = taskInfo.get(0).topActivity; | ||
| return topActivity != null && topActivity.getClassName().contains("EnforceDataActivity"); | ||
| } |

The method isEnforceDataActivityOnTop has a few issues that should be addressed:
- Potential Crash:
am.getRunningTasks(1)can return an empty or null list, which would cause anIndexOutOfBoundsExceptionontaskInfo.get(0). You should add a null/empty check for the returned list. - Deprecated and Unreliable API:
ActivityManager.getRunningTasks()has been deprecated since API level 21 and its use is discouraged for application logic. It might not work as expected on newer Android versions and can even break in future releases. A more reliable approach would be to useActivityLifecycleCallbacksor a flag within your application to track whetherEnforceDataActivityis active. - Fragile Class Name Check: Using
String.contains()to check the activity's class name is not robust. It's better to use an exact match with the fully qualified class name:EnforceDataActivity.class.getName().
Here's a suggested improvement that addresses the crash and the class name check. I strongly recommend replacing the deprecated API for a more robust long-term solution.
public boolean isEnforceDataActivityOnTop() {
ActivityManager am = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);
if (taskInfo == null || taskInfo.isEmpty()) {
return false;
}
ComponentName topActivity = taskInfo.get(0).topActivity;
return topActivity != null && topActivity.getClassName().equals(EnforceDataActivity.class.getName());
}
