歌曲中內建專輯圖片和未帶專輯圖片獲得方法1.    歌曲中內建專輯圖片解壓音樂檔案本身內建的壓縮圖片資料作為專輯封面。2.    歌曲中不帶專輯圖片如果音樂檔案本身不存在圖片資料，則在本目錄尋找AlbumArt.jpg檔案；若AlbumArt.jpg不存在，則尋找以albumart開頭、large.jpg結尾的檔案；若albumart開頭，large.jpg結尾的檔案也不存在，則尋找任何檔案名稱包含albumart的.jpg檔案；若再找不到，則使用檔案夾目錄下任何.jpg檔案；若以上都不符合，則

In order to securely access an online service, users need to authenticate to the service—they need to provide proof of their identity. For an application that accesses a third-party service, the security problem is even more complicated. Not only

Just as your application can send data to other applications, so too can it easily receive data from applications. Think about how users interact with your application, and what data types you want to receive from other applications. For example, a

So far we've talked about accessing Google APIs, which use accounts and users defined by Google. If you have your own online service, though, it won't have Google accounts or users, so what do you do? It turns out to be relatively straightforward to

Beginning in Android 3.0, using the SearchView widget as an item in the action bar is the preferred way to provide search in your app. Like with all items in the action bar, you can define theSearchView to show at all times, only when there is room,

Implementing an effective and user friendly share action in your ActionBar is made even easier with the introduction ofActionProvider in Android 4.0 (API Level 14). An ActionProvider, once attached to a menu item in the action bar, handles both the

There are many ways to store your data, such as in an online database, in a local SQLite database, or even in a text file. It is up to you to decide what is the best solution for your application. This lesson shows you how to create a SQLite virtual

Suppose you are implementing a crowd-sourced weather service that makes a global weather map by blending together pictures of the sky taken by devices running your client app. Integrating photos is only a small part of your application. You want to

The SearchView and action bar are only available on Android 3.0 and later. To support older platforms, you can fall back to the search dialog. The search dialog is a system provided UI that overlays on top of your application when

Your application has a job to do, and integrating videos is only a small part of it. You want to take videos with minimal fuss, and not reinvent the camcorder. Happily, most Android-powered devices already have a camera application that records

Factory mode test item cannot display 如果factory mode的測項不能正常顯示，請首先參考檢查以下原因： 原因一：factory.c的ftm_test_item[]中未定義該測項        請務必確定alps/mediatek/factory/src/factory.c中ftm_test_item[]數組中定義了該測項。               static item_t ftm_test[] = {       #ifdef FEATURE_

int (*(*F(int,int)))(int)是什麼類型？首先，int(*M)(int)，其中M為函數指標，則(*F)(int,int)=M，用N代替*F，F為指向N的指標，則N(int,int)=M，這表示N是一個函數，參數為2個int,其傳回值為函數指標M。故F為函數指標，該函數指標所指向的函數的參數為2個int,傳回值為函數指標。另：int a;int F();可以想象成F()=a，即表示F是個函數，其傳回值為a的類型。上面的N(int,int)=M中，N(int,int)與M同類型，

Directly controlling a device camera requires a lot more code than requesting pictures or videos from existing camera applications. However, if you want to build a specialized camera application or something fully integrated in your app UI,
