[Tool] Add Multiwindow-option to almost every apk files

---

Hey,

I've programmed a small windows tool to add the multiwindow option to almost every apk file.

Disclaimer: Please follow the instructions at your own risk. I will not be held responsible if your device or its data gets damaged in the process of following this guide.

Instructions:
1. Copy the wanted app with a root explorer from data/app (installed apps) system/app (system apps) to a mountable storage like /sdcard or /mnt/extSdCard
2. Connect your device to the Windows PC and copy the stored apps (see section 1) to your pc.
3. Start the Tool and select the files (see section 2) as source path
4. If you have selected the selection mode folder you can select the wanted apps in the list by checking the boxes.
5. Select a destination Path
6. Execute the tool by pressing the green triangle at the top.
7. Copy the modified app to the tablet
8. Backup the app with an backup app (i recommend titanium backup)
9. Uninstall the app
10. Install the modified apk
11. Restore the produced backup data (only data not application)
12. You should now be possible to select the app in the multiwindow view.

Thank u! Like this tool!

I used it already for a few apps. One app that haven´t worked was ezPDF. If i want to start in fullscreen it crashes, but when i start in window mode it works till i resize.

Any idea?

I used the program but when it's finished and I clicked "yes" to goto destination folder, there's nothing there. The app I'm trying to convert is viggle version 1.0.9

Hey, do you start the application as administrator? if not that could be a problem, or select another destination path. In case of an error in the tool there should be a "multiviewapmodifier.log" in your documents folder you can open it with any text editor and send me the error text, maybe there is the information i need to tell you how you can solve this problem.

i don't have ezpdf to test it but some apps make problems with this mod, thats the reason why i wrote almost every apk

Cool mod, thanks. I just ordered a GN 10.1 today and will be pre-ordering the GN2 on Verizon next week when I am eligible for an upgrade.

I have the same problem, here's my log :

System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\kd\AppData\Local\temp\com.adobe.reader-1\AndroidManifest.xml'.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy)

at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize)

Somehow, it doesn't decompress properly...


Edit: In my case, java's bin folder wasn't in my PATH variable. As soon as I fixed that, everything started working.

Do we download and run the tool then select the apk or what ..

yes, you have to download the tool (its a windows application), run it, select a source and destination path for the apk and then press the execute button, after that you have to reinstall the modified apk and voilà the app should be displayed in the multiscreen window =) very usefull for people who use an alternative browser like chrome or just want to launch the 2 favorite apps at the same time. But as i told you, there are some apps which doesn't can get modified like uccw (problem with the used decompile/recompile interface) if you have any problems pls first try to run it as administrator

Thank you

Dont think that the multi window keep after updating the app, think the modified part of the apk will get overwriten after update, but i'm not certain.
