Android ndk compilation and use of static and dynamic libraries

 

 

Ndk compiles and uses static and dynamic libraries

Case 1: Compile the static library

Case 2: Compile the dynamic library

Case 3: Compile the dynamic library + static library

Scenario 4: existing third-party static libraries (dynamic libraries), compiling static libraries (dynamic libraries)

 

By default, all codes and files are under $ Project/JNI. Otherwise, special instructions are provided.

Case 1: Compile the static library

File Android. mk:

Local_path: = $ (call my-DIR)
Include $ (clear_vars)
Local_module: = hello-JNI
Local_src_files: = hello-jni.c
Include $ (Build _Static_ Library)

 

File application. mk:

App_modules: = Hello-JNI

 

Case 2: Compile the dynamic library

File Android. mk:

Local_path: = $ (call my-DIR)
Include $ (clear_vars)
Local_module: = hello-JNI
Local_src_files: = hello-jni.c
Include $ (Build_shared_library)

Case 3: Compile the dynamic library + static library

File Android. mk:

Local_path: = $ (call my-DIR)

Include $ (clear_vars)
Local_module: = mylib_static
Local_src_files: = SRC. c
Include $ (Build_static_library)

Include $ (clear_vars)
Local_module: = mylib_shared
Local_src_files: = src2.c

Local_static_libraries: = Mylib_static

Include $ (Build_shared_library)

Scenario 4: existing third-party static libraries (dynamic libraries), compiling static libraries (dynamic libraries)

File Android. mk:

Local_path: = $ (call my-DIR)

Include $ (clear_vars)
Local_module: = thirdlib1 # name it whatever
Local_src_files: =$ (Target_arch_abi)/libthird1.a# Or $ (so_path)/Libthird1.so
# Local_export_c_includes: = $ (local_path)/include
Include $ (Prebuilt_static_library) # OrPrebuilt _Shared_ Library

Include $ (clear_vars)
Local_module: = mylib_use_thirdlib
Local_src_files: = SRC. c

Local_static_libraries: = Thirdlib1 # OrLocal_Shared_ Library

Include $ (Build_shared_library) # If a static library is compiled, application. mk is required.
