delete(String table, String whereClause, String[] whereArgs)

update(String table, ContentValues values, String whereClause, String[] whereArgs)

这是什么String[] whereArgs？它与"？"相关联 (所谓的外卡)？

我做了一个SingleItemAdapter扩展ArrayAdapter,这个定制的适配器用于ListView.

在这里SingleItemAdapter,我做了一些数据库的东西,所以我想在getView()初始化GUI的方法中抛出异常.

但public View getView(int position,View convertView,ViewGroup parent)抛出异常会得到Exception Exception is not compatible with throws clause in ArrayAdapter.getView(int, View, ViewGroup)

ArrayAdapter,BaseAdapter,Adapter不会抛出异常,为什么呢？

Now i create a new project include c++ support in Android Studio 3.2, it has native-lib.cpp naturally, the CMakeLists.txt looks like this:

add_library( # Sets the name of the library.
    native-lib

    # Sets the library as a shared library.
    SHARED

    # Provides a relative path to your source file(s).
    src/main/cpp/native-lib.cpp)

now if i build this project, i can find libnative-lib.so in some "debug" directoies, that's OK, but i want static library ie .a files.

Change SHARED to STATIC won't generate …
