Why package manager dies and throws failed binder transaction every 5th time? How to work out this issue?

Vote count:

0

I have just only one package manager, a global one which im using everywhere. I have an ImageButton and onClick function. I am able to click 4 times in a row on image, and it works, slow but works and seems fine, almost the way I want it to work. But when I click on the ImageButton 5th time, 10th time, 15th time and etc, my app crashes. I've been looking around for answer and figured out that The Binder transaction buffer has a limited fixed size, currently 1Mb. But that shouldnt work every 1st time if buffer is overflown. Logcat:

Code:

private boolean appInstalled(String uri)
    {
        boolean app_installed = false;
        try
        {

            } catch (JSONException e) {
                e.printStackTrace();
            }
        } else {

            PackageNames = new ArrayList<String>();

        }
        int flags = PackageManager.GET_META_DATA | PackageManager.GET_SHARED_LIBRARY_FILES | PackageManager.GET_UNINSTALLED_PACKAGES;
        List<ApplicationInfo> packageList = packageMngr.getInstalledApplications(flags);

        for (ApplicationInfo pack : packageList) {

            if ((pack.flags & ApplicationInfo.FLAG_SYSTEM) != 0 || AppNames.contains(pack.loadLabel(packageMngr).toString())) {
            } else {
                AppNames.add(pack.loadLabel(packageMngr).toString());
                PackageNames.add(pack.packageName);
                CheckedItems.add(false);
            }
        }
        Editor editor = sharedAppPreferences.edit();
        String AppNamesBuffer = new JSONArray(AppNames).toString();
        String PackageNamesBuffer = new JSONArray(PackageNames).toString();
        String CheckedItemsBuffer = new JSONArray(CheckedItems).toString();
        editor.putString(AppsListKey, AppNamesBuffer);
        editor.putString(PackageNamesListKey, PackageNamesBuffer);
        editor.putString(CheckItemsListKey, CheckedItemsBuffer);
        editor.commit();
        AppList appList = new AppList();
        appList.show(getSupportFragmentManager(), "AppList");
    }

Line 150 would be: packageMngr.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);

And line 180: if (appInstalled(PackageNamesBuffer.get(i).toString())) {
