android 添加预装的方法

方法1：

 frameworks/base/services/java/com/android/server/pm/PackageManagerService.java

      synchronized (mPackages) {

            mHandlerThread.start();

            mHandler = new PackageHandler(mHandlerThread.getLooper());

+            if(SystemProperties.getBoolean("persist.sys.firstRun", true)){

+                File targetDir = new File("/data/app");

+            File dir  = new File("/system/media/app");

+            if(dir.exists()){

+                for(File file : dir.listFiles()){

+                    File targetFile =  new File(targetDir,file.getName());

+           FileUtils.copyFile(file,targetFile);

+            FileUtils.setPermissions(targetFile.getAbsolutePath(), FileUtils.S_IRUSR| FileUtils.S_IWUSR | FileUtils.S_IRGRP| FileUtils.S_IROTH, -1, -1);

+                }

+           }

+            SystemProperties.set("persist.sys.firstRun","false");

+        }

            File dataDir = Environment.getDataDirectory();

方法二：

init.rc中添加：

+chmod 0777 /system/bin/preinstall.sh

+service preinstall /system/bin/preinstall.sh

+       class main

+        user root

+        group root

+        oneshot

+        console

+        disabled

on property:dev.bootcomplete=1

    chown media media /sys/class/vm/mirror

    chmod 0664 /sys/class/vm/mirror
+    start preinstall

    write /sys/class/vm/mirror 0

    start usbpm

preinstall.sh

#!/system/xbin/busybox sh

echo "do preinstall job"        

if [ ! -e /data/system.notfirstrun ]; then

  echo "do preinstall job"        

        pm install /system/preinstall/xxx.apk

        touch /data/system.notfirstrun

else

   echo "do nothing"

fi

xx.mk

PRODUCT_COPY_FILES += \

$(LOCAL_PATH)/preinstall.sh:system/bin/preinstall.sh

# pre-installed apks

PRODUCT_COPY_FILES += \

        $(call find-copy-subdir-files,*.apk,$(LOCAL_PATH)/apk,system/preinstall)

 

方法二（二）

init.rc

on property:init.svc.bootanim=stopped

    start preinstall

service preinstall /system/bin/preinstall.sh

    user root

    group root

    disabled

    oneshot

xx.mk

ifeq ($(BUILD_WITH_THIRDPART_APK),true)

PRODUCT_PACKAGES += \

    preinstall.sh \

  $(patsubst vendor/amlogic/prebuilt/preinstallation/%,%,$(wildcard vendor/amlogic/prebuilt/preinstallation/*.apk))

endif

preinstall.sh

#!/system/bin/sh

MARK=/data/local/symbol_thirdpart_apks_installed
PKGS=/system/preinstall/

if [ ! -e $MARK ]; then
echo "booting the first time, so pre-install some APKs."

busybox find $PKGS -name "*\.apk" -exec sh /system/bin/pm install {} \;

# NO NEED to delete these APKs since we keep a mark under data partition.^M
# And the mark will be wiped out after doing factory reset, so you can install^M
# these APKs again if files are still there.^M
# busybox rm -rf $PKGS^M

touch $MARK
echo "OK, installation complete."
fi
