How to stop "permission denied" app toasts after denying permissions? I often like to deny app permissions that I think the app does not need but yet they keep requesting for the permissions even after Denying, resulting in lot of toasts [package name] has been denied [permission name] permission.

How do I permanently suppress these toasts?

I am using android Kitkat.
I believe your primary aim is to turn off some permissions. So I will form my answer to that direction.

If you are rooted:

Choice 1: Since you are referring to toasts, there is a way to turn them off using the xposed module Untoaster. I wish I could tell you how to use that, but I currently cant use xposed due to compatibility issues. SO this, you may have to test and figure out your self.

Choice 2: You can also try using lucky patcher. It can disable permissions. To do this, open lucky patcher and grant it root rights. Then browse to app/package name whose permissions you want to block and tap on it. Then select the option Edit Permissions and tap on permissions to enable/disable them. Be careful though, you may end up messing up the app.

If you are not rooted:

In this case, we will modify app permissions to the core. We will edit a minor code/xml so app doesn't even know of those permissions. Yes, it is a very DIRTY trick. There are consequences.


Firstly, download APKTool. Refer this guide on how to use (you will be using the compiling/decompiling and signing features).
Firstly, get the app's apk. You can either use some app backup program or use Terminal Emulator. If you decide to go with terminal emulator, open it and run these commands:


mkdir /sdcard/apps123

cp /data/app/*.apk /sdcard/apps123

This will copy all the APK files installed by you inside apps123folder in your internal sdcard.


After you have got the apk and decompiled it, go to apktoolDirectory/projects/[package name you decompiled] folder and open AndroidManifest.xml with some editor (Notepad++ recommended.
After you have opened the file, look for permission lines. They will have the format:




(In this case, its permission to write internal storage).


Delete out lines corresponding to permissions you do not want. All permissions are defined at beginning of xml so you dont need to explore the whole manifest.
After you are done, compile app again and sign it. Put it to phone and install.


------> You can also have a look at this documentation to see what each permission does.

NOTE: There is also an android version of APKTool. You can install and use it in phone itself. Its much more easier to use but takes longer time to complete tasks.

----> This method wont give you toast notifications like now.

Drawbacks of this method:


You wont be able to update app from play store anymore.
Whenever app tries to access that feature whose permission is missing, it will cause a security exception and app is likely to crash unless developer has handled it (which they normally dont).
