android-4.4-kitkat

问题 I am aware about changes in Access to SD card introduced by Google with Android 4.4. However in my application I need to be able to store data on some removable /secondary sd card. When I create the application folder (app.xyz.com) on the secondary using default file manager then I am able to create dirs and files inside. But by default such dir dosen't exist on secondary sd card. So, I would like to create the application specific dir programmatically inside my application… Do you have any

问题 Through my application the user can choose a file from the filemanager and process the choosen file ( Example: A PDF document ) for other steps like printing or to email.

问题 This question already has answers here : How to disable the Recent Tasks/Apps button (5 answers) Closed 3 years ago . We have an industrial control app we write and ship pre-loaded on Samsung Galaxy Tablets with our manufacturing products. The tablets we were using were Tab 10's which ran Honeycomb, but we can't get enough of those to OEM anymore so we're switching to Tab 4's which run KitKat. The new tablets have a button which looks like the old menu button - two overlapping rectangles -

问题 I recently upgraded to Android 4.4 and someone of the features of my app have surprisingly stopped working. I have this code for initializing and then drawing my custom view. The basic idea is it adjusts the zoom level so the entire view fits on the screen. private void initAtZoomLevel(float zoomLevel){ .... Matrix transformMatrix = new Matrix(); transformMatrix.setScale(initialZoomLevel, initialZoomLevel); float yTransCenter = (screenHeight - mapHeight)/2.0f; setImageMatrix(transformMatrix);

问题 The Problem I want to implement the new RemoteController API, which has been introduced with API19 (Kitkat,4.4). The API requires me to implement a class which extends from NotificationListenerService (introduced with API18) and implements the RemoteController.OnClientUpdateListener interface.

问题 I'm using the windowTranslucentStatus in my app theme. Now, also want to tint the status bar to match my ActionBar. Currently I'm using the SystemBarTint library, which is mostly fine except of one problem: When the application launches, the OS shows a themed mockup layout as a splash image during the actual inflation. At that stage, there is no status bar tinting yet. It looks like that (Took me 5 times to capture this screenshot during app launch): Only after the activity is fully loaded

问题 I work for a company that makes an SD memory card that includes a hardware encryption engine. We interact with the encryption module by writing/reading to a special file. Starting with KitKat, the O_DIRECT flag does not seem to be supported on the external SD card. Without O_DIRECT or O_SYNC support, the OS will returned cached data when we read the encryption engine's response from the SD card (via our special file). Is there a procedure to open a file on the eternal SD card, read/write,
