Question about waitForPauseToComplete() blocking behavior

[aliaschoondy]

While reviewing AxmolPlayer.java, I noticed that waitForPauseToComplete() can block indefinitely while waiting for mNativePauseComplete:

while (mNativePauseComplete.getCount() > 0) {
    try {
        mNativePauseComplete.await();
    } catch (InterruptedException e) {
        Log.e(TAG, "Pause wait interrupted", e);
    }
}

During a code review, it was suggested that an indefinite wait on the Android lifecycle path could potentially cause the main thread to remain blocked if the latch is never released.

I experimented with the following change:

private static final long PAUSE_COMPLETE_TIMEOUT_MS = 2000;

final CountDownLatch latch = mNativePauseComplete;
if (latch == null) {
    return;
}

try {
    if (!latch.await(PAUSE_COMPLETE_TIMEOUT_MS, TimeUnit.MILLISECONDS)) {
        Log.w(TAG, "Timed out waiting for native pause to complete");
    }
} catch (InterruptedException e) {
    Thread.currentThread().interrupt();
    Log.e(TAG, "Pause wait interrupted", e);
}

I do not currently have ANR traces or a reproducible failure case. This was suggested as a defensive improvement to avoid waiting indefinitely on the UI thread.

Before using or contributing this change, I’d like to understand:

• Is the indefinite wait intentional?
• Are there scenarios where timing out could leave the engine in an inconsistent state?
• Would a timeout-based approach be acceptable, or is there a better way to handle this situation?
