[Guide] Long press menu button to kill app

majdinj · May 31, 2013

This mod will make you able to instantly kill app activity by long press on menu button

The original mod is done by maskerwsk, who modifies Mirko_ddd method

Needed tools:
1) Backsmali/Smali program from here
2) Notepad++ program from here
3) WinRAR or 7-zip archiver

The procedure:
- Backsmali android.policy.jar
- Navigate to classout/com/android/internal/policy/impl/ folder and open PhoneWindowManager.smali file
- Locate the following code by tracking "mMenuLongPress" and do the following changes:
before:

Code:

    .line 1674
    new-instance v0, Lcom/android/internal/policy/impl/PhoneWindowManager$[B][COLOR="Red"]9[/COLOR][/B];

    invoke-direct {v0, p0}, Lcom/android/internal/policy/impl/PhoneWindowManager$[B][COLOR="Red"]9[/COLOR][/B];-><init>(Lcom/android/internal/policy/impl/PhoneWindowManager;)V

    iput-object v0, p0, Lcom/android/internal/policy/impl/PhoneWindowManager;->mMenuLongPress:Ljava/lang/Runnable;

after:

Code:

    .line 1674
    new-instance v0, Lcom/android/internal/policy/impl/PhoneWindowManager$[B][COLOR="Blue"]KillConcept[/COLOR][/B];

    invoke-direct {v0, p0}, Lcom/android/internal/policy/impl/PhoneWindowManager$[B][COLOR="Blue"]KillConcept[/COLOR][/B];-><init>(Lcom/android/internal/policy/impl/PhoneWindowManager;)V

    iput-object v0, p0, Lcom/android/internal/policy/impl/PhoneWindowManager;->mMenuLongPress:Ljava/lang/Runnable;

N.B: $9 might be differ according to ROM, but track "mMenuLongPress" to locate the wanted code portion

- Save changes.
- Now add this new file (PhoneWindowManager$KillConcept.smali) to classout/com/android/internal/policy/impl/ folder. You can download it from here.

You should make sure that the id in PhoneWindowManager$KillConcept.smali is linked to "permlab_forceBack" id in framework-res.apk public.xml. See post #15 to know exactly how it is done.

- Now recompile (smali) the classout folder and open android.policy.jar by WinRAR or 7-zip and substitute classes.dex inside android.policy.jar with the new classes.dex file.. now push the modified android.policy.jar to your device and fix permissions to chmod 644.

Extra step:
To adjust timeout delay, backsmali framework.jar and navigate to classout/android/view/ folder and open ViewConfiguration.smali and search for this method and change RED text value:

Code:

.method public static getGlobalActionKeyTimeout()J
    .registers 2

    .prologue
    .line 669
    const-wide/16 v0, [B][COLOR="Red"]0x1f4[/COLOR][/B]

    return-wide v0
.end method

As you can see, this hex value means 500; i.e, 0.5 second.. So we will change it to which delay we want:
0x1f4 = 0.5 second (default value)
0x2ee = 0.75 second
0x3e8 = 1 second
0x4e2 = 1.25 second
0x5dc = 1.5 second
0x6d6 = 1.75 second
0x7d0 = 2 second

N.B: applying this change, will affect the timeout delay across OS!!

Now you can open any app and then long press the menu button to exit instantly..

Is it possible to control delay before an app gets killed?

No in the meantime,,, but may be in future, since it involves complicated coding and decompiling other system app..

Then it's safe to presume it doesn't exist

You could follow the steps on the OP, then make a flashable zip with the modded files, open a new thread and get a million thanks

yes.. the only problem is that i'm not able to do it..

You should make sure that the id in PhoneWindowManager$KillConcept.smali is linked to "permlab_forceBack" id in framework-res.apk public.xml

as I can check this? could you specify a bit more please

Yes..
1. decompile framework-res.apk
2. go to decompiled folder res/values folder and open public.xml file
3. search for permlab_forceBack. It will be something like this:

Code:

    <public type="string" name="permlab_forceBack" id="[B][COLOR="Blue"]0x01040245[/COLOR][/B]" />

As you see here our targeted id is 0x01040245
4. now open PhoneWindowManager$KillConcept.smali and locate this portion:

Code:

    .line 885
    move-object/from16 v0, p0

    iget-object v14, v0, Lcom/android/internal/policy/impl/PhoneWindowManager$KillConcept;->this$0:Lcom/android/internal/policy/impl/PhoneWindowManager;

    iget-object v14, v14, Lcom/android/internal/policy/impl/PhoneWindowManager;->mContext:Landroid/content/Context;

    const v15, [B][COLOR="Blue"]0x1040245[/COLOR][/B]

    const/16 v16, 0x0

    invoke-static/range {v14 .. v16}, Landroid/widget/Toast;->makeText(Landroid/content/Context;II)Landroid/widget/Toast;

    move-result-object v14

    invoke-virtual {v14}, Landroid/widget/Toast;->show()V

As you can see, I just match the id to be exactly the same like the one in public.xml of framework-res.apk (you should omit the first 0 digit; i.e, 0x01040245 will be 0x1040245)

thanks for the reply: D, and the other is whether it is possible that instead of occupying occupy menu button back?

I don't know if I understand the question, but menu button will not be affected by the mod,, it will have another function that is long press to kill..
if you mean long press back button to kill, believe me this one is much easier to mod than back to kill since back button has multi-window function as well which you need to deal with during coding as well.

Thanks for mod. Do I navigate to PhoneWindowsManager.smali using RootExplorer?

No.. You need to pull the framework to the pc. Then decompile it using any of the available methods. The navigate to the file you specified. Open it in notepad++ and do the editing.

No. Use apktool to decompile and then notepad ++ to mod the smalies.
