Might be because you are running a custom rom. If you like, and want to upload that rom's framework-res.apk and systemui.apk, I'll see if I can make a magisk module for 3Minit.
Hi Tulsadiver,

I read your many posts and learned a lot :) Thanks for that!

I tried your VR Theme magisk module, but it didn't work on Android 11 out of the box. Android was complaining that resources.arsc has to be uncompressed when targeting R+ (version 30 and above). However I figured that part out (by adding that file with the zip -0 option).

But it does not seem to be possible anymore to modify the framework-res.apk in Android 11 (AOSP custom)? It seems that Android is actually checking the signature but fails to "collect certificates" and bootloops ...

I guess there is no way to overcome this problem (because I don't have the signing key)? But then I am wondering how your mods work on Android 11? Maybe the ROMs you have are less strict?

I attached the framework-res.apk that I am trying to change (res/values/integers.xml line 178).
I don't modify the framework values folder.

Just a quick update. The solution is basically to create an overlay instead (RRO).
For better understanding for beginners:
3Minit Battery modification is done in the SystemUI.apk only, but to be able to de- and recompile this apk correctly, you need to install framework-res.apk (and maybe other fliles depending on your rom).
Additionally you have to add 3MinitBatteryResources.apk to system/priv-app and install 3Mintbattery.apk as user app.
But you do not modify the framework-res.apk

I can't remember if it starts with android 10 or 11, but most SystemUI's are deodexed already even though they still contain oat folders. Unzip your SystemUI.apk with 7zip or similar to see if you have .dex files in it.

Edit: it appears that it started as early as Android 9

    That's curious. Shouldn't make any difference if you're smali-modding as that oat folder has to be deleted. But I wonder why they do that. Maybe they just can't be bothered removing the dex files..

      Well, thank you! What with the manic pace of my offline life, I had forgotten TMA's birthday. It's good to see somebody's paying attention!
      Same here dude. Glad you're still hanging with TMA. Sucks that things aren't like they used to be. Anyhow, I'm still using your TMA almost on a daily basis.

      TMA is a quick, powerful and easy-to-use tool that uses a piece of java called "apktool" to decompile and recompile Android app's.

      Along with that, Tickle My Android offers the ability to:

      • decompile and recompile multiple files in a batch,
      • sign APK and JAR files
      • zipalign APK files,
      • create flashable ZIP files,
      • let you choose between multiple versions of Apktool
      • lets you theme up to eight different roms or devices at the same time,
      • use the tool in different languages
      • control the tool by keyboard or MOUSE!
      UjezkPM.jpg


      To use Tickle My Android, you will need:

      • - a rooted Android phone or tablet with USB Debugging enabled and a custom recovery installed,
      • - any version of Android on that device,
      • - a Windows PC (XP or above) with the phone or tablet's drivers installed,
      • - Java Runtime Environment 8.0 or above installed to your PATH (http:​//www.​java.​com/en/download/help/path.​xml​),
      • - a USB cable to connect your device to the PC,
      • - patience and a little common sense
      If you're running Android 4.3 or above, you'll also need to give USB Debugging permission on your phone when this sort of message pops up on the screen:

      (Thanks to @carl1961​ for the picture)

      Download the latest version from the link at the top of this post and run it. (Please don't look in the 'Downloads' tab - it's not working right now.) This is a self-extracting archive which, once it's extracted everything, will put on your PC a new folder called "Tickle My Android". This is where the tool runs from.

      pIzCZ9F.png


      The "_WorkArea1", "_WorkArea2", "_WorkArea3", "_WorkArea4", "_WorkArea5", "_WorkArea6", "_WorkArea7" and "_WorkArea8" folders we'll talk about later.
      The "tool_files" folder contains various files Tickle My Android needs to run. Don't touch these!
      The "user_files" folder holds different versions of Apktool, as well as the different language files.

      And the "Tickle My Android" exe file starts the tool. Double click on that and away we go!

      How To De/recompile An App​​

      Decompiling and recompiling an Android app for the first time can seem quite complicated and time-consuming, but it really isn't once you know what you're doing.

      First you'll need to choose which WorkArea you want to use. There are eight WorkAreas in total, which means you can easily work on up to eight different rom's or devices without having to reset the tool everytime you want to change from one to the other.

      Inside each WorkArea are five folders. The '_in' folder is where files about to be decompiled go, the '_working' folder contains the results of that decompiling and the '_out' folder contains the recompiled files. There's also a "Frameworks" folder, which will contain the framework files you've installed. You can pretty much ignore that last one most of the time.

      F4Zywlz.jpg


      (When you first use TMA,​ you'll be in WorkArea 1 by default.)

      To decompile an app, you'll first need to put the relevant APK in the "_in" folder. You can either copy this into the folder yourself or you can 'pull' it from your Android device. If you want to pull the file, this next section is for you. If you don't, skip ahead to the one after that.

      How To Pull A File​​

      First select the "Pull File From Device" option.

      gwr61eZ.jpg


      This gives you the option of pulling some of the most commonly modified system apps, or any other file you wish.

      Choose which file you want to pull and the tool will try to do that for you. If the pull fails, it could be that you don't have the adb drivers installed on your PC for your particular device, or the file doesn't exist, or any one of a number of things. Have a look in the "history.txt" file that's automatically generated to see what's going on.

      That's actually all we need to know about pulling - it's really not that complicated. Once you've pulled all the files you need, you can move on to decompiling them. But you might need to install your frameworks first..

      How To Install Framework Files​​

      If you want to modify a system app (like SystemUI.apk or framework.jar) you'll need to install the right framework files. These are files that contain resources that are shared amongst most of the system apps. Those resources need to be made accessible to apktool (the program that does the actual decompiling) or the app won't decompile fully and it won't work.

      There are many framework files available. Stock Android only comes with one (so far) and it's called "framework-res.apk". OEM's like to include their own, though, just to make life more interesting. Samsung used to have "twframework-res.apk" in their rom's before replacing it with "samsung-framework-res.apk". Framework files are found in "system/framework" on your devices internal memory and should be an APK file with "res" in the filename. You need to make sure you install every framework file in your rom to ensure a system app decompiles, so make sure they all are put in the "_in" folder.

      Select the "Install Framework File" option and choose whether you want to install all the framework files in your WorkArea or some individual ones. You can select up to five individual files to install in one go.

      GJ1Lj72.jpg


      If the tool isn't able to install the files you'll be shown an error, otherwise you'll go back to the install menu. If you've installed all the framework files you need to, go back to the title menu because we're finally ready to do some decompiling!

      How To Decompile A File​​

      Select the "Decompile File" option and choose whether you want to decompile all the files in the "_in" folder or individual ones.

      aZjvlEg.jpg


      Once you've chosen your files, you'll be asked whether you want to decompile with "Standard" or "Advanced" settings. This is new to Version 16 of Tickle My Android. Apktool has a lot of different options when it comes to decompiling and you can now choose which ones you want to use. The standard settings will just make the tool try to decompile the entire file, as it used to in previous versions. The advanced settings let you control the process a little better..

      wG4iPVA.jpg


      These are the main decompile options available for the latest version of apktool available at time of writing (2.4.0.). Full explanations of each are available on the apktool github here: https://ibotpeaches.github.io/Apktool/documentation/#decode. To give you an idea though, you can use "Don't Decode DEX Files" if you don't want to modify any smali files, which makes the decompile a lot faster!

      Choose your options and the tool will try to decompile your file for you. If it succeeds the decompiled files will be in the "_working" folder, if not you'll get an error message. The full details of that error will be in the "history.txt" file.

      Once your app is decompiled you will be free to modify it however you like. Change images, alter layouts, add functionality..whatever you want to do. When you're done, you'll need to recompile your app to be able to use it again.

      How To Recompile A File​​

      Select the "Recompile File" option and choose whether you want to recompile all the files in the "_working" folder or individual ones.

      eGCpZA2.jpg


      Once you've chosen your files, you'll again be asked if you want to recompile with standard or advanced settings.

      jWTBDZO.jpg


      You can find explanations of the first few options on the apktool github again: https://ibotpeaches.github.io/Apktool/documentation/#rebuild. It is very important to know what the options that you've selected but there are two that's worth paying extra attention to..

      "Copy Original "AndroidManifest.xml" And "META-INF" Folder" - Modified system apps need to be signed with the same 'key' as the original app, or they won't run. This option ensures that the original key is used on the new app. If you want to change the Manifest file, though, you'll need a different key which involves disabling signature verification. That's a bit more complicated than this tool allows for..

      "Use "aapt2" [apktool_2.3.2+]" - More recent apps can be constructed with a newer version of a tool called aapt. If you're trying to modify a file made with the newer version, you'll need to have this option actve for the recompile to work. There's no easy way to tell if this is needed or not so, if you get an error, try again with the option turned off.

      (Different versions of apktool will have different options. Selecting an option that isn't available on the version of apktool you're using will cause an error.)

      There are also options to sign and zipalign your recompiled apps. Signing uses a generic key and zipaligning can sometimes break V2 signature checks so, if you've no idea what that all means, it's best to leave these options alone until you know you need them.

      And TMA has an option to put your recompiled apps into a ZIP file that you can flash in a custom recovery. I'll go into this in more detail in the next post but I always recommend replacing system apps this way. It's much safer than trying to replace them while the phone is running.

      Choose your settings and sit back while the tool does its thing.

      Once it's finished you'll get a message saying the file recompiled...or one saying it didn't. If it didn't, you can find the full error text in history.txt.

      9MFPZcY.jpg


      If your file recompiled, you'll find it in the "_out" folder. It's now ready to go back to your phone.

      It's up to you how you do that but the route I always recommend above all others is using a flashable ZIP file. Check out the next post if you want to know more!

      How To Create A Flashable ZIP File​​

      Once you've got a recompiled app, you need to put back to your phone. If you've modified a system app, I always suggest using a flashable ZIP file in recovery. That way you're replacing part of the system, while the system isn't running. Using a file manager app, or using adb, is asking for trouble. I've broken a tablet that way and nearly a phone as well.

      Tickle My Android can create that flashable ZIP for you and it's really easy to do so. You can either tell the tool to do it as soon as the app's recompiled, or use the dedicated option on the title screen.

      UjezkPM.jpg


      To start, select the "Create Flashable ZIP File" option from the title screen. You'll then be asked if you want to use files from the "_in" folder or "_out" folder. This can be handy if you want to make a flashable ZIP of the unmodified apps. I normally have at least one of those containing my original SystemUI.apk just in case a mod goes wrong.

      Next you'll be asked to choose your files. You can add up to five files to the flashable ZIP. Once you've confirmed which file, or files, you want to use you'll be asked where those files are going in the ZIP.

      GTU8KTS.jpg


      Make sure your apps go back to the right folder. If you put a modified framework-res.apk in the "system/app/" folder, for instance, those modifications won't be actioned.

      Once you've chosen where the files are going, you'll next be asked what filename you want the ZIP file to have. TMA will automatically generate one for you based on the current date and time, but you can have whatever filename you want. Make sure not to use too many special characters or it could confuse the tool and/or the recovery. If you want to use the default filename, just press ENTER.

      G5CBBKi.jpg


      The tool will now ask you to confirm all the details.

      xNsZKe6.jpg


      If you're happy, then the ZIP will be made and placed in the same folder as the tool.

      E5GrJNB.jpg


      Copy this to your phone, flash it in reoovery and enjoy! But always, always, always make sure you have a backup first!!

      F.A.Q.​


      Having trouble using Tickle My Android?
      Something not making sense?
      Something not working the way it should?
      Read on..

      Q. I can't de/recompile something!

      A. With Android being open-source, more and more companies and developers are putting their own spin on the OS and it's not unusual to find that something won't compile even when there's no obvious reason why it should.

      I can help..but you need to do something for me first.

      In the tool's folder, you'll find a file called 'history.txt'.

      Share that file with me and let me know a little bit about what's going wrong.

      That should give me enough information that I will be able to fix your problem. :)

      Please be aware that I won't be able to help you without this information.

      Q. I'm getting a 'Java Not Installed" error...but I do have Java installed!!

      fioJPbK.png


      A. You may have Java installed...but you probably don't have it in your PATH.

      TMA is a batch file, which runs in a command-line environment. If you don't have Java in your PATH, the tool won't be able to access it and won't be able to do any decompiling or recompiling at all.

      Adding Java to your PATH is actually a lot easier than it seems. Have a look at the official guide here: [url]http://www.java.com/en/download/help/path.xml[/URL]

      I started this thread on the 3rd of May 2012.

      That's 5 years ago.

      And that's really shocking. Where have all the years gone??

      To mark the occasion, I just wanted to say a big THANK YOU to everybody who's downloaded TMA, helped with debugging and new features, and all the wonderful people who post on here. I know there are other decompiling and deodexing tools out there. Your support means a lot to me, it really does.

      TMA is still going. I'm not working on a new version yet, not until Android O means I have to change things yet again, or until I come up with a new feature. But this tool and this thread are still very much live. And everybody who's reading it and this post are automatically the greatest people ever!
