[Android] MoPub – App freeze on startup

我使用的是320×50 banner ad thru MoPub SDK for Android,使用的 SDK 是 mopub-sdk:[email protected], 遇到的問題是,有時候主畫面會被卡住,從logcat 來看,會程式會掛掉的 log:

說明:發現正常執行時,會丟出 D/MoPub: Posting AsyncTask to main thread for execution. 這段 debug code 是從 mopub 的 asynctask class 所丟出:
https://github.com/mopub/mopub-android-sdk/blob/master/mopub-sdk/mopub-sdk-base/src/main/java/com/mopub/common/util/AsyncTasks.java

public static <P> void safeExecuteOnExecutor(final @NonNull AsyncTask<P, ?, ?> asyncTask, final @Nullable P... params) {
    Preconditions.checkNotNull(asyncTask, "Unable to execute null AsyncTask.");

    if (Looper.getMainLooper() == Looper.myLooper()) {
        asyncTask.executeOnExecutor(sExecutor, params);
    } else {
        MoPubLog.d("Posting AsyncTask to main thread for execution.");
        sUiThreadHandler.post(new Runnable() {
            @Override
            public void run() {
                asyncTask.executeOnExecutor(sExecutor, params);
            }
        });
    }
}

發現,註解掉 mPersonalInfoManager = MoPub.getPersonalInformationManager(); 可以降低mopub 造成UI freeze 的問題。如果在 activity.onCreate() 時,同時執行 MoPub.initializeSdk() 還有 MoPub.getPersonalInformationManager() 大約試3~4次即可試出一次 freeze, 註解掉 MoPub.getPersonalInformationManager(), 連試 10次 UI 都沒被卡。

暫時解法,透過 handler.postDelayed(new Runnable() { 把程式執行時間錯開,降低卡住機率,多試幾次還是會被卡住一次,這是是 mopub 蓋了一個更高蓋的 view , view 下面的 UI 還是可以被主程式控制和修改UI,問題是被蓋了一個 Loading 在整個程式上面,整個程式都無法被點選和操作。
