(1) In the Android. mk file, you must specify the local_path variable to find the source file. GenerallyAndroid. mk is in the same directory as the source file to be compiled, so it is defined as follows:Local_path: = $ (call my-DIR)The preceding statement defines the local_path variable as the directory path of the cost file. (2) Multiple compilation modules can be defined in Android. mk. Each compilation

Here is a basic introduction of Android development of some of the basic knowledge, in the development of practical applications, the most commonly used references are: The Developer ' s Guide Android References Android Resources The last one is google.com:-). After the application is written, after testing on the

. nativeactivity. -The Android: Name attribute of the meta-data tag must be set to Android. App. lib_name. lib_name does not have the Lib prefix and. So Suffix of the module. 3. Create a file to implement the anativeactivity_oncreate () function for the activity to be called at startup.

However, there are also many interesting things.In this article, we will mainly discuss how to implement

data set for an application available to other applications. Other apps can get or deposit data from the content provider through the Contentresolver class.(2) Content providers are required only if you need to share data between multiple applications.

thinking that your program is "Frozen ". Because these threads are generally completed through classes, you can think of the application response issue as a class-level problem, which corresponds to a performance issue generally at the method level. This article describes how the Android system judges that an application is unresponsive and provides a guide to improving application responsiveness. What triggers ANR? (What triggers ANR ?) In

Chapter 2 Hello, l10n (localization) In this chapter, we will create a hello, l10n application that will selectively load some resources based on the android framework. Then we add some resources to the res/directory and use this method to localize our applications.3.1 create an unlocalized Application In the first hello, l10n version, we only use the default resource directories (RES/drawable, Res/layout,
