Why would u change the package name? If someone tries to change it then they might not have nice intentions, just leave it to crash lol

nah i just trying to play normal game and modded game same time.

wdym not work, give more info about what happens, if its still crashing then just put logs to check where it crashes, fire up cmd or from the phone terminal and type:

adb logcat -s "Testing" (if u have adb and u are in windows)

if u have a terminal in the phone just do
logcat -s "Testing"

then on the smali just put different logs like so:
 

const-string v2, "Testing"

const-string v3, "Passed first call"

invoke-static {v2, v3}, Landroid/util/Log;->e(Ljava/lang/String;Ljava/lang/String;)I

............. (call another function)

const-string v2, "Testing"

const-string v3, "Passed second call"

invoke-static {v2, v3}, Landroid/util/Log;->e(Ljava/lang/String;Ljava/lang/String;)I

then open the apk and check in the logcat what passes and what not.

 

i figured out but i have a another issue if main package name is changed protection is not working and closing app.

not worked

Check with this, an activity is already an instance of Context so u should be fine by calling getContentResolver directly i think.

i posted my code

I trying to mod a apk. I created a small smali code for check device id and if id if not equal its closing the app. But its crashing instantly (not exitting). I adding these lines to OnStart function. And extra information i modding cocos2dx game.

The code:

invoke-virtual {p0}, Lorg/cocos2dx/cpp/AppActivity;->getApplicationContext()Landroid/content/Context;

move-result-object v0

invoke-virtual {v0}, Landroid/content/Context;->getContentResolver()Landroid/content/ContentResolver;

move-result-object v0

const-string v1, "android_id"

invoke-static {v0, v1}, Landroid/provider/Settings$Secure;->getString(Landroid/content/ContentResolver;Ljava/lang/String;)Ljava/lang/String;

move-result-object v0

const-string v1, "810b0fb3128d05bc"

if-eq v0, v1, :cond_19

const/4 v0, 0x1

invoke-static {v0}, Ljava/lang/System;->exit(I)V

:cond_19

ty

thanks
