有platform signature的APK,成為system Apps,  就有root的權限,做一些su才能做的事

//---如何platform signauture
方法之一
把Eclipes做的APK source拷到
BSP\development
加入如下Andriod.mk

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
# Only compile source java files in this apk.
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_PACKAGE_NAME := Cat007    <--------------------這個要改 br="">LOCAL_SDK_VERSION := current
LOCAL_CERTIFICATE := platform
#LOCAL_MODULE_TAGS := tests
include $(BUILD_PACKAGE)
# Use the following include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))


source, lunch, 再到該目錄下編譯APK
mm -B
再到BSP\
make
生成的system.img就包有該APK,並具有root權限
(所以每一次測試APK都要10 min   T_T       )


//--- stop apk   , 例如代入"com.example.cat002"
    public void btn_1(View v) {
        EditText et1 = (EditText) findViewById(R.id.editText1);
        String pkg = et1.getText().toString();
        ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
        Method forceStopPackage;
        try {
            forceStopPackage = am.getClass().getDeclaredMethod(
                    "forceStopPackage", String.class);
            forceStopPackage.invoke(am, pkg);
        } catch (Exception e) {
        }
    }
需加permission
   


//--- install apk silently , 例如代入"com.example.cat002"
    public void btn_3(View v) {
        EditText et1 = (EditText) findViewById(R.id.editText1);
        String pkg = et1.getText().toString();
        pkg="pm uninstall "+pkg;
        try{
            Runtime.getRuntime().exec(pkg );
        }catch(Exception e){
        }
    }

需加permission
