[Think Tank] Getting Google Market (vending.apk) to work without google apps.

In adding google apps support to my last 2.0 rom, I experimented a lot of things and, of all the google apps programs, Vending was the one that was the most interesting to me because I noticed that the program would not force-close like the others with other missing google apps, the program just exits, so it's safe to assume that it's looking for a login somewhere. Even after GoogleApps.apk is removed, the market will still work, something it won't do if you don't sign in before removing GoogleApps. All it seems to require are the two permissions in etc (com.google.android.gtalkservice.xml and com.google.android.datamessaging.xml).
Now, here's what I think, if we're able to look what Vending is looking for and create a small app to generate the necessary login information and put it where needed as best-case goal. A more realistic goal, though, would be to look at the smali code and see where the login information is being requested and causes the program to shut off if it's not available. If we find it, we can just bypass it and have the program start without a login, and I believe the only thing that would be affected would be the cloud storage of the apps we've downloaded, but we'd still have full access to market.
Trying to start the app alone gives me this error:
Code:

12-02 10:42:41.273: WARN/AudioFlinger(375): write blocked for 95 msecs, 69 delayed writes, thread 0xcd90
so, theoretically, if we have onAuthTokenComplete() ignore the result from completeGetAuthToken() of if we modify completeGetAuthToken() to pass something to onAuthTokenComplete() something to allow the program to start, we should be good to go.
Testers, ideas, experiences?.

I guess this is where we start com.android.vending.BaseActivity.smali:
Code:
.method private completeGetAuthToken(ILandroid/content/Intent;)Ljava/lang/String;
.registers 6
.parameter "resultCode"
.parameter "data"
.prologue
const/4 v2, 0x0
.line 1328
const/4 v1, -0x1
if-ne p1, v1, :cond_11
.line 1329

.line 1330
.local v0, extras:Landroid/os/Bundle;
if-eqz v0, :cond_20
.line 1331

invoke-virtual {v0, v1}, Landroid/os/Bundle;->getString(Ljava/lang/String;)Ljava/lang/String;
move-result-object v1
.line 1338
.end local v0 #extras:Landroid/os/Bundle;,
:goto_10
return-object v1
.line 1333
:cond_11
if-nez p1, :cond_20
.line 1334
invoke-virtual {p0, v2}, Lcom/android/vending/BaseActivity;->setResult(I)V
.line 1335

new-array v2, v2, [Ljava/lang/Object;

.line 1336
invoke-virtual {p0}, Lcom/android/vending/BaseActivity;->finish()V
.line 1338
:cond_20
const/4 v1, 0x0
goto :goto_10
.end method

Try the youtube app, it will insert login data when you log in with your gmail account.

I think this is it, again, at com.android.vending.BaseActivity.smali:
Code:
.method protected final onAuthTokenComplete(Lcom/android/vending/BaseActivity$AuthService;Ljava/lang/String;Z)V
.registers 6
.parameter "service"
.parameter "authToken"
.parameter "performRetry"
.prologue
.line 1083
if-eqz p2, :cond_d
.line 1084
iget-object v0, p0, Lcom/android/vending/BaseActivity;->mApplication:Lcom/android/vending/VendingApplication;
invoke-virtual {v0, p1, p2}, Lcom/android/vending/VendingApplication;->setCachedAuthToken(Lcom/android/vending/BaseActivity$AuthService;Ljava/lang/String;)V
.line 1085
if-eqz p3, :cond_c
invoke-virtual {p0}, Lcom/android/vending/BaseActivity;->doRetry()V
.line 1089
:cond_c
:goto_c
return-void
.line 1087
:cond_d
const-string v0, "null auth token."
const/4 v1, 0x0
new-array v1, v1, [Ljava/lang/Object;
invoke-static {v0, v1}, Lcom/android/vending/util/Log;->d(Ljava/lang/String;[Ljava/lang/Object;)V
goto :goto_c
.end method
p3 takes you to cond_c which is an auth login retry
p2 looks like it loads the vending app and then tries to get pass AuthService() to setCachedAuthToken(), and if that fails takes you to "null auth token" tossed into log.

Progress!!!!
I got the app to load without closing by removing all calls to onAuthTokenComplete, completeGetAuthToken, and onActivityResult.
Now I'm stuck at the ToS page, it won't load anything, so I'll try to bypass that.

past the ToS and stuck at market "Loading" screen.
removed the call to forwardIfNeededToTosActivity in BaseActivity.
Here's where I'm at right now, all necessary files inside, should work on a vanilla build of master. Either update.zip flash it or adb push it, whatever.
I'm tired, need sleep
Hope somebody else works on this too.

Cant sleep without this suggestion. Hopefully somebody is reading and can make it work.
At this point, I think we're just requiring a login so we can browse market. Search never completes, browse never completes, and I think it's because we're not logged in. If we pull whatever necessary bit from /data/data/com.android.vending from a working market build and toss it in, it should, theoretically again, work. If we remove the personal logins and pass it something generic, it should work too.
I'm still bothered by something, though, what happens with paid apps? Probably a force-close.
Anyway, I hope google at least releases a "free market" app that's standalone and we can toss into generic builds without anything else needed so we can at least download free apps.

it's a database problem.
I know nothing of sqlite so this is as far as I get

use youtube app to login.

either you already have it working or you're just suggesting that I use youtube app to login. I tried it but doesn't work with my hacked market. Is there another way that you know of?

Have you logged in with your Google or with your YouTube account?

Yeah, I tried it with my google account (and it's already synced to my youtube account). I then opened up the market app I attached to an earlier post and still hanged at the "Loading" screen.
I then pushed a full Market app, which dutyfully force-closed due to the missing GoogleApps.apk, I then pushed it, SetupWizard, Checkin, and the rom started boot-looping so I gave up

how to use Market.zip?thank you!

Launched on CyanogenMod v5.0.7 (Android 2.1) Dream
In order to launch Market app you need Vending.apk, GoogleApps.apk, GoogleCheckin.apk, SetupWizard.apk, TalkProvider.apk, gtalkservice.apk and these framework files:
Code:
/system/etc/permissions/com.google.android.datamessaging.xml
/system/etc/permissions/com.google.android.gtalkservice.xml
/system/framework/com.google.android.datamessaging.jar (often absent, seems works without it)
/system/framework/com.google.android.gtalkservice.jar
/system/lib/libgtalk_jni.so
Vending.apk, GoogleApps.apk, SetupWizard.apk, gtalkservice.apk should be placed only on /system (because they require privileges that can be acquired only there, like WRITE_SECURE_SETTINGS, see https://www.isecpartners.com/files/iSEC_Securing_Android_Apps.pdf), GoogleCheckin.apk & TalkProvider.apk probably can be placed anywhere (but I didn't try).

no success
I have try it follow your instructions,
but with no success;
it stays in the UI "Searching..."
any suggestion？
I put your vending.apk to /system/app/,
and the com.google.android.gtalkservice.jar to /system/framework/;
and
com.google.android.gtalkservice.xml
com.google.android.datamessaging.xml
to /etc/permissions/
am I right?

this would be crucial if I could get this too work. I have a Camangi WebStation, which runs a custom Cupcake 1.5 with NO GAPPS or Market even worse NO Google Maps. I would love to get Google Maps to work on it, cause it has a GPS, but no GPS app or Maps function. But yeah it dont have the Google branding, so it doesnt have any important Google Apps.
If this could be implemented to work on other devices, it would be freaking nice

This doesn't work, at least in it's current form, and I have no interest on working on it. This was from when we had the infinite sync problem with eclair and I wanted to make a rom without gapps and just market.
Also, this is not for users, this was for dev help to try to make a googlelogin that vending could use after bypassing the check for googleapps.
Mod, please close this thread.

Where to get
com.google.android.datamessaging.xml etc.,
Please let me know
thanks

I USE THIS SETUPS
adb remount
adb push whatever.apk /system/app (put an apk in your sdk tools and replace "whatever" with the name of the apk and this
will push it to your system app folder. You can change the destination as well for example: You want to push Launcher2.apk
to your data/app folder: adb remount
adb push Launcher2.apk /data/app )
but when i type adb remount in cmd show this error

[MOD/Source] Remove carrier tab/channel from market

Hey everyone, I just posted this in the Vibrant forums, but its universal, anyone on Android that hates the carrier tab in the market, here's a solution!
Ok, so while I was re-theming the newest market update for myself, I was finally annoyed enough with the carrier tab/channel in the android market to find a way to disable it entirely.
Simple, SIMPLE change takes care of it.
Decompile Vending.apk, and open /com/smali/android/vending/AssetBrowserActivity.smali
look for the following line:
Code:
invoke-virtual {v5}, Lcom/android/vending/model/GetCarrierInfoResponse;->isCarrierChannelEnabled()Z
a couple of lines beneath that, comment out the following two lines:
Code:
if-eqz v5, :cond_4
if-eqz v2, :cond_4
And then immediately after you've commented those out, add the following:
Code:
goto :cond_4
So the final code in my Vending.apk looks like this:
Code:
invoke-virtual {v5}, Lcom/android/vending/model/GetCarrierInfoResponse;->isCarrierChannelEnabled()Z
move-result v5
# if-eqz v5, :cond_4
# if-eqz v2, :cond_4
goto :cond_4
And voila, no Carrier tab/channel anymore!
PLEASE NOTE! This will remove the carrier tab entirely, there is no way to browse the carrier channel using this method.
Anyway, hopes this helps someone else too.
Cheers everyone, =)

[APP][MOD][TUT]Discussion: Plex w. Android TV UI for ANY DEVICE

So, I have a Nexus Player, and I absolutely LOVE the way the UI for Plex looks on it. It has a number of added categories and features, and overall, it's just really pretty, and highly preferable to the regular "TV" option in the Plex app.
Unfortunately, the good folks at Plex decided to reserve this only for Android TV...which sucks. I just bought a RikoMagic V5 Rk3288-based Android on a stick to replace my aging RK2066 device, and when it arrives, I'd like the same sexy experience as I have on the Nexus player.
I can already install the leanback launcher...so why not get the plex UI to go with it?
So that's what I did.
EDIT: LOL. So, instead of modifying the APK, it looks like we can just add the permission file it's checking for to /system/etc/permissions/ I've attached it...simply download, extract, copy to /system/etc/permissions, and reboot. Presto! Pretty plex.
I'll leave the other method simply because it's good to know how to do, and can be applicable to many other situations.
HOWEVER, there's an obvious problem. You either have to have purchased the app, or have a Plex Pass to use it. I have not explored the paid version of the app yet, just the Plex Pass one...but that will be done shortly. First I wanted to share my discovery.
Basically, the check for whether or not the device is an Android TV lives in \smali\com\plexapp\plex\application\PlexApplication.smali when you decompile the APK.
In this method:
Code:
.method public B()Z
.locals 2
invoke-virtual {p0}, Lcom/plexapp/plex/application/PlexApplication;->a()Z
move-result v0
if-eqz v0, :cond_0
invoke-virtual {p0}, Lcom/plexapp/plex/application/PlexApplication;->getPackageManager()Landroid/content/pm/PackageManager;
move-result-object v0
const-string v1, "android.software.leanback"
invoke-virtual {v0, v1}, Landroid/content/pm/PackageManager;->hasSystemFeature(Ljava/lang/String;)Z
move-result v0
if-nez v0, :cond_1
:cond_0
const/4 v0, 0x0
:goto_0
return v0
:cond_1
const/4 v0, 0x1
goto :goto_0
.end method
Here, the code is obfuscated, but the original method is called isAndroidTV. Either way, searching for "android.software.leanback" should get you into the method.
Now, all this is really doing is asking the system if it has the flag "android.software.leanback", so we could probably modify build.prop? to have that flag and be right with the world. But, I haven't tried that yet.
Instead, if we read through what the method is doing, we can see that if it finds "android.software.leanback", it goes to condit_1, which sets const v0 to 0x1, or a "yes" return. So, what if it fails? It runs to cond_0, which instead sets const_v0 to 0x0, or "no".
So, the obvious fix to this is to just make cond_0 return 0x1, or the following code:
Code:
.method public B()Z
.locals 2
invoke-virtual {p0}, Lcom/plexapp/plex/application/PlexApplication;->a()Z
move-result v0
if-eqz v0, :cond_0
invoke-virtual {p0}, Lcom/plexapp/plex/application/PlexApplication;->getPackageManager()Landroid/content/pm/PackageManager;
move-result-object v0
const-string v1, "android.software.leanback"
invoke-virtual {v0, v1}, Landroid/content/pm/PackageManager;->hasSystemFeature(Ljava/lang/String;)Z
move-result v0
if-nez v0, :cond_1
[B][U] :cond_0
const/4 v0, 0x1
[/U][/B]
:goto_0
return v0
:cond_1
const/4 v0, 0x1
goto :goto_0
.end method
That's it. Just flip the 0x0 to a 0x1 and recompile the apk. Due to it being a Play Store app, it's also necessary to resign with a test key so we can install it.
Here is a link to the final output that I was able to install on my 5.0.1 (lollipop) GPE ROM running on a HTC M8. At this time, I'm unsure whether it will A. Work on a non-lollipop ROM or B. Work on a ROM that doesn't allow test-key signed apps.
However, it is a working proof of concept, and could prove useful to others who use android devices as media center devices.
Also, attached is a screenshot of the POC, albeit looking poor on my phone.
Feel free to try the attached APK and let me know how it works for you. Mods - this is the free Plex Pass version - aside from changing the above .smali, I have not modified or circumvented any other security features (like making it work for everybody). You must have a Plex Pass account to use this.

Post2: Compatibility testing, screenshots.
So, I was able to successfully install the apk on a stock, unrooted Galaxy Tab 4 running android 4.4.2, so it looks like this should work for a lot of people. Screenshots attached. It looks beautiful on a tablet, and despite being made for TV, all touch input works properly.

can you mod the non-plexpass version of plex to do this?

Unfortunately, it doesn't look like they've pushed that UI to the non-pass version. More than likely, they'll roll it out to all users in the next update or the one after that - at least - that's how Plex usually does things.
When that happens, I'll *still* not be able to release it, as it's a paid version of the app. However, it's possible I could provide a tool to do all the work for people who do have it.

Digitalhigh,
I cannot thank you enough! love your work.
Rob.

I tried it on my xiaomi mibox mini which is running Android 4.4.2. The app starts in leanback mode and I can browse the contents but can't play anything

[How to] whitelist packages on almost any MTCD head unit

Assumptions:
The unit should be rooted. Otherwise you can’t update system files.
MTCManager.apk should be de-odexed. I was able to do this successfully with "Tickle my Android". Thanks to post below for the suggestion.
The unit is configured for auto-sleep (not delayed shutdown)
Background:
When the unit goes to sleep, most processes and services are “killed”. There is an app by Graser, which goes by the name Dasaita and runs as an Xposed module, that allows apps to be whitelisted and then they will not be killed. However it doesn’t at this time work in Oreo, at least in my experience, and it does not work on Services so it doesn’t help with accessibility services.
General procedure:
1. Extract mtcmanager.apk from the head unit
2. Decompile mtcmanager.apk with apktool.exe
3. Edit a smali file
4. Recompile
5. Copy over the original apk (make a backup of course)
6. Set permissions and owner
7. Restart the HU
Details:
1. The location of MTCManager.apk is /system/priv-app/MTCManager. It requires a file manager that uses root to access it. I like Root Explorer. Copy to USB or SD.
2. Locate apktool and follow the installation instructions to install on a Windows machine. I don’t know if it is or isn’t available for a Unix or Linux machine (or a mac). Make MTCManager.apk readable on the machine where apktool is installed. Enter the command
Apktool d -o <where to decompile> <full path to MTCManager.apk>
Recommend entering “MTCManager.apk” with the original capitalization so it’s easy to copy back.
3. On Oreo the file is c.smali. There are two lists, the first is services and the second processes. Malaysk has added Tasker to both lists. I add as required to both lists. One app didn’t work exactly right and it helped to remove it from the process list.
Note there is a constant before each list specifying the list length.
Adding to the lists is a simple programming task. Roughly speaking duplicate 3 lines of code,change the index (subscript) and app name string, for each of the packages to be added to each list.
4. Enter the command apktool b -c <path where it was decompiled>
This will create a directory called “dist”, containing the modified apk.
5. Copy the new apk to usb or sd, then on the HU copy over the original mtcmanager.apk. Overwriting seems to be the most reliable way to install.
6. Use the file manager to change the permissions to 644, and the owner and group to <root>.
7. Restart the HU.

Thank you for the instructions. This got me started on the right path. However I believe the instructions above are missing a step. You also need to increase the size of the array(s) if you are adding additional applications to the whitelist.
My original c.smail I had the following starting in line 222:
const-string/jumbo v1, "net.dinglisch.android.tasker"
const/16 v2, 0x19
aput-object v1, v0, v2​
This is the last entry added by Malaysk in the services section.
These lines do the following:
Copy "net.dinglisch.android.tasker" to the variable v1
Copy 0x19 (decimal 25) to the variable v2
Add v1 ("net.dinglisch.android.tasker") to Array v0 at position v2 (25)
If you are not using tasker, then you can just replace "net.dinglisch.android.tasker", with the application of your choosing. Otherwise you must add another row to the array.
First you must increase the size of the array.
Starting on line 57 I had:
const/16 v0, 0x1a
new-array v0, v0, [Ljava/lang/String;​
These 2 lines establish array v0.
Copy 0x1a (decimal 26) to the variable v0
Create array v0 of size v0 (26)
To increase the size the array so that you can add another entry, change this to:
const/16 v0, 0x1b
new-array v0, v0, [Ljava/lang/String;​And add a new entry below the tasker entry:
const-string/jumbo v1, "com.teslacoilsw.launcher"
const/16 v2, 0x1a
aput-object v1, v0, v2​The entire process must be repeated again, if you wish to add to the process section.
On line 232 I had:
const/16 v0, 0x1b ==> Changed to 0x1c
new-array v0, v0, [Ljava/lang/String;​Added below tasker entry on line 404:
const-string/jumbo v1, "com.teslacoilsw.launcher"
const/16 v2, 0x1b
aput-object v1, v0, v2​After compiling with apktool, copying MTCManager.apk to the head unit and rebooting, everything works as expected.

Is it possible to post your modified apk ? Are you on malaysk Oreo ?

Yes I'm on Malaysk Oreo.
I can post the apk, but since I only added com.teslacoilsw.launcher & de.dieterthiess.ipwidget, I'm not sure it will do you much good.

I am at Malaysk Oreo and my c.smali is not the same at line 57.
I would like too to see how have you modified the file, as Wout2426 says I want to do it but I don't really understand your post and it would be nice to have an example to understand it.
I've tried to change tasker for another task (radardroid) and it is working well. Now I want to whitelist more tasks, not only replace tasker.
Thanks in advance

Sorry for the delay, but I've been out of town. This is my modified c.smali from Malaysk Oreo version 1.1.

I followed the guide, decompiled the MTCManager.apk. Replaced the tasker entry into com.ankai.cardvr (my dashcam app), re-compiled, and put it in system/etc/mtcmanager, with 0644 permission.
And, it works. After hu is started dvr app starts. It's a dashcam with it's own sd card, so it will start recording anyway, but now it shows correct time and gps coordinates in the time stamp.
Thx guys !

Hi! I have a problem with recompilation. I copied mtcdmanager for from unit. Inside I have a APK file and directory oat\arm64 with odex files. When I execute apk tool it creates original dir and res. I can't find c.smali file anywhere. I'm using stock Oreo
Ok I get it, needs to be deoxeted.

Greg

Rather than whitelisting, is it possible to modify MTCManager so it doesn't kill anything?

That's a good question. I may try it at some point.

Id be really interested, but can't try myself due to stock rom and missing GPS slot.
By revising the c.smali, did you find the Clearprocess.java mentioned at the top? Should be stated to kill everything in that class..?

I like that the device sleeps. I dislike that the device kills the services
Will be looking at a non-root way to get this working (or an easy way to root haha)

I am now more interested, I'm finding mild instability after wake. Yes, c.smali mentions Clearprocess.java.
Update: I am trying a "no kill" solution, I have added a line "return v5" in the methods ha and gz close to the top of each, just after the two constants. HU is working ok. I added an accessibility service and confirmed it persisted. I'm not sure what else to test. I will see what I notice in use.

Nice, tell us more when you got time to test.
Ive had some troubles decompiling/recompiling and found that my used framework was outdated.
Advanced apktool from xda got me the right framework AND to get the whole thing to work, you have to sign the apk after recompiling..
Though, any additions work as intended.
Cheers

Also give this a try for a non root approach

I've been running no-kill for a week with no problems. Occasional crashes in Gmaps and Google have stopped it seems.

That's awesome! Mind posting your fixed apk for those of us having compilation issues?

little more details for the smali noobs would be cool tho
Found that adding FCC launcher to the whitelist makes it unresponsive after wake, but removing it will stop the clock ^_^

Could you upload your no-kill version of mtcmanager? I have been trying to compile my own version but no luck so far. Thanks!

[GUIDE] How to make your GCam mod work without Gapps or microG

notice: I have only tried this with two APKs, with similar versions. Older or newer versions might differ. Here be dragons.
If you're someone like me, who don't install Google apps on your phone for one reason or another, but still want to use Google Camera for the quality improvements it brings, this topic might help you out!
If you didn't know, not having Gapps installed will usually make Google Camera crash right away, even if your phone's compatible with the mod you are using. My workaround for this was setting up microG and disabling it's Google server connections, but I wanted to learn modding APKs, so I thought this would be a good way to start on it. Fortunately, this was very easy to do, as not many features depend on Gapps.
Requirements:
Intermediate knowledge on Android tinkering
A GCam APK for your phone, preferably one that can disable Google Photos and Lens integrations (which will probably stop working with this patch)
apktool
adb
1. Open the camera and get the crash stacktrace through adb logcat. You will need this to find out which class to edit.
In the following stacktrace snippet, the bolded part is what you will be looking for. For the rest of this guide, the name of the class is assumed to be 'kas'.
Code:
java.lang.RuntimeException: Unable to create application com.google.android.apps.camera.legacy.app.app.CameraApp: java.lang.SecurityException: Failed to find provider com.google.android.gsf.gservices for user 0; expected to find a valid ContentProvider for this authority

<snip>
2. Decompile the APK, and find the class
Not much to explain here. apktool and the find command (for *nix at least) should work pretty well. You will probably find it under ./smali.
3. Find some interesting fields
In the smali file, near the top, you will see two private static final fields with the type of android.net.Uri. In my case, they are named b and c (will refer to them as kas.b or kas.c from now on)
Code:
.field private static final b:Landroid/net/Uri;
.field private static final c:Landroid/net/Uri;
Inside the constructor you should find two strings with com.google.android.gsf.gservices. We need to trace the constructor to find out which one maps to which field:
Code:
const-string v0, "content://com.google.android.gsf.gservices"
invoke-static {v0}, Landroid/net/Uri;->parse(Ljava/lang/String;)Landroid/net/Uri;
move-result-object v0
sput-object v0, Lkas;->c:Landroid/net/Uri; # put v0 into [B]kas.c[/B]. this might be referred to as [B]field 1[/B] later on
const-string v0, "content://com.google.android.gsf.gservices/prefix"
invoke-static {v0}, Landroid/net/Uri;->parse(Ljava/lang/String;)Landroid/net/Uri;
move-result-object v0
sput-object v0, Lkas;->b:Landroid/net/Uri; # put v0 into [B]kas.b[/B]. this might be referred to as [B]field 2[/B] later on (URI ends with /prefix)
This step is needed because the order of these fields change between versions and different obfuscations.
4. Delete the broken parts
Now, do a search for ContentResolver;->registerContentObserver in the file. There should be a single result.
Go upwards and find the sget-object call for field 1 (kas.c).
Delete everything in between, and including, sget-object and invoke-virtual
Then, do another search for Lkas;->b (kas.b / field 2), and find the only sget-object line containing it.
Then, delete the invoke-virtual/range and the following move-result-object lines.
Scroll a little lower, and replace the if-eqz v1 line after the new TreeMap with a goto.
5. Pack it up
Build the APK, sign/align and push into your phone. It should be good to go!

I have found a very simple solution: install the apk linked there https://github.com/lukaspieper/Gcam-Services-Provider and GCam is working without gapps!
