AutoPatcher uses Deflate compression method & normal compression level to repack jar. I think this will not affect in performance. I will try to improve the compression process if possible. But, I need a uncompressed jar file. If you got one, please send me the jar via PM.

I just tried this on Resurrection Remix 5.8.4 where the original services.jar was 6.93 MiB and the patched services.jar is 3.09 MiB.

Why is the patched file size less than half of the original file size?

Patched jar compression process has been improved in new build. Now, AutoPatcher will try to detect compression method of original jar, then patched jar will be repacked in same way. Download the latest build from here https://xdaforums.com/attachment.php?attachmentid=4283664&d=1506406860

How do I know if the framework.jar patch is working?

I don't see any difference with the paths

Internal SD card = /sdcard
External SD card = /storage/0000-0000/

I used the AutoPatcher on copies of services.jar and framework.jar. I then copied the automatically created SDPath file to /sdcard and then installed the patched jar files from within the recovery environment. Lastly I cleared the davlik-cache and rebooted.

This doesn't make any defference between above two paths. The changes will affect on applications, which are uses ExternalStorage to read/write files. Normally your device/phones storage is ExternalStorage for all apps. But, after patching your Removable SDCard Storage will be treated as ExternalStorage for all apps. As example before patching framework files AutoPatcher app was located you to phones storage when you clicked "Select File" button. After patching the path is swiched to SDCard Storage.

@Vighneswar
For uTorrent- you have to select SDCard path manually when you add a torrent link to download. To select SDCard path manually use "Up" button instead of using dropdown list, when you are in "InternalStoarage/Download". I guess, this app will remember your last selected path for next download attempt.

For Flud- change the path manually to SDCard in "settings->storage->Storage path" of this app or clear application data (Note: this will reset all setting & data of this application) or uninstall & reinstall the app.

I am not much sure the above trick will work for you. You can follow these trick, if you are agree to test. Please note that, I will note be responsible if you lose anything.

Hi guys,
I have developed an android application to patch framework.jar & services.jar automatically. The application have attached in attachment.

Instructions :-
a) Download & install the AutoPatcher.apk from attachment.
b) Copy /system/framwork/services.jar and /system/framework/framework.jar to External Storage.
c) Open the application & select services.jar or framwork.jar to patch by clicking on "Select File" button.
d) Select a patching option from patching options list.
e) Click the "Patch" button to patch the jar file.
f) Create flashable zip with patched file/files & flash the zip from recovery.

Can anyone test the app & report me back its working correctly or not?

Thanks..

EDIT: Attachment updated (Installation issue fixed).
EDIT: Attachment updated (Bug fixed).
a) Fixed issue with Jar selection.​
b) Fixed issues with patching framework.jar.​
c) Fixed issue: Can't boot after flashing the patched files.​

EDIT: Attachment updated (Removed unnecessary files from apk package)
EDIT: Attachment updated (Improved patched Jar compression process)

To test if writing to sdcard works I open terminal emulator and try to
touch /storage/0000-0000/test.txt
If successful the file will be created. If not you only can write with android framework regular mechanisms to allowed folders or using root elevation to access all folders.

I also used my mod in RR 5.8.5 & it worked. Anyway, here is your patched framework files- https://drive.google.com/file/d/0B7ssgT5S39JbM3I2aGNaVG5TYWM/view?usp=drivesdk

Make a flashable zip with these patched files, flash it from recovery, wipe dalvik-cache & reboot.

If not work, you may need to reinstall full ROM & then flash patched files. Please take a backup of your current ROM before doing this.

    ​

    Note:-     After modifying your framework files by following the below tutorial all system & user apps will have the permission to write external SD Card without asking to user. Please keep backup of your ROM before doing anything. I will not be responsible for any damage or boot loop.

    Method 1 : Automatic patch
    Auto Patcher app :
    I have developed an android application to do all the patching work automatically. To download please click here- https://xdaforums.com/showpost.php?p=73854657&postcount=84


    Method 2 : Manual patch

    Requirements :-

    a) framework.jar & services.jar of your ROM.
    b) Apktool to decompile & recompile jar files.
    c) Notepad++ to edite smali files.
    d) 7zip to add modded .dex files into original .jar files.
    ​


    Step 1:- Giving write permission to External SD card.
    a) Decompile services.jar with APKTool. Go to com/android/server/pm/ directory.
    b) Open PackageManagerService.smali with Notepad++ & find the below method.

    Code: 
    .method private grantPermissionsLPw(Landroid/content/pm/PackageParser$Package;ZLjava/lang/String;)V
    c) Go to end of this method & add below Red color marked lines of code accordingly in their corresponding place.
    ​

    Code: 
    .method private grantPermissionsLPw(Landroid/content/pm/PackageParser$Package;ZLjava/lang/String;)V

    d) Recompile framework.jar. Open original framework.jar & modded framework.jar with 7zip in side-by-side window. Drag N Drop classes.dex file from modded framework.jar to original framework.jar window. Now keep the framework.jar in a safe place.
    ​

    Flashing modified files.
    Create a flashable zip with moded framework.jar & services.jar. If you are using Redmi Note 4G. Then download attached zip file from attachment, open with 7zip, Add both jar file into "system/framework/". Then flash with custom recovery, wipe dalvik-cache & reboot. It will take up to 5 min.

    ​
    Creating setting file.
    a) Create a new file in "/data" directory. Rename it to "SDPath".
    b) Then open the file "SDPath" with text editor. Then add the following line & save.
    ​
    Code: 
    ext_SD=1
    If you want to switch back the SD Path to default, just change the value from 1 to 0.

    ​
    Enjoy.....
