Application with MTK preset detachable

Create a new system bin to copy the APK when it is started. The specific implementation is as follows:

1. This is a feature. To enable or disable this function for various projects, you need to define macro control;

Add:

Rgk_preinstall_app_uninstall = Yes

 

2. Create a folder under Code \ External:

This folder contains the files required for this bin. Name customization. do not duplicate the name with the existing bin. Here we set it to userapp, and create a c file under userapp to copy the APK:

Create copyapp. C:

# Include <ctype. h>

# Include <errno. h>

# Include <fcntl. h>

# Include <getopt. h>

# Include <limits. h>

# Include <Linux/input. h>

# Include <stdio. h>

# Include <stdlib. h>

# Include <string. h>

# Include <sys/reboot. h>

# Include <sys/STAT. h>

# Include <sys/types. h>

# Include <time. h>

# Include <unistd. h>

# Include <dirent. h>

 

# Define buffer_size 1024

3. Create an MK file under userapp:

Create Android. mk:

Ifeq ($ (Strip $ (rgk_preinstall_app_uninstall), yes)

Local_path: = $ (call my-DIR)

Include $ (clear_vars)

Local_src_files: = copyapp. c

Local_module: = userapp

Include $ (build_executable)

Endif

 

4. Add the implemented bin to init. Rc. Add the following to init. RC under code/mediatek \ config \ ratech75cu_nand_gb2:

Service userapp/system/bin/userapp

Oneshot

It indicates that our bin is executed once during initialization.

 

5. Add the following to the user_tags.mk file in the code/build/Core directory:

Grandfathered_user_modules + = userapp

6. Create the pre_install directory under the Code \ vendor directory, which stores the app files pre-installed and detachable, and create a new Android. mk file:

Android. mk content:

Ifeq ($ (Strip $ (rgk_preinstall_app_uninstall), yes)

Include $ (clear_vars)

Local_path: = vendor/pre_install

Product_copy_files + = \

$ (Local_path)/qqsecure2.0_android.apk: System/pre_install/qqsecure2.0_android.apk

Endif

7. You need to remove the copy statement of the app in the Android. mk file in the Code \ vendor \ third_party directory.
