Android 2.x on Emulator with Market?

I know this has been asked around the place quite a bit, but I haven't read an answer on xda and this place seems to be the best place to get answers, so I'm going to ask it...
Is it possible to run up Android 2.1 or 2.2 on the emulator with the market? I've got 1.5 and 1.6 running fine but haven't worked out how to get 2.x working. It's really bugging me that I can't find a good answer as to whether or not it is possible.
And if not, can someone tell me why?
Thanks in advance!
BTW: my first post!

[Q] Two versions of one app installed at the same time?

It seems that this is the first time I start a new thread.
Hi, all. I want to know how to install two versions of one same application at the same time.
As a matter of fact, I want to install Opera Mini 4.2 China Version and Opera Mini 4.2 Internaional Version at the time. But...Since Opera Mini 5 makes it difficult to describe the question, here takes HelloWorld.apk as an example.
Well, there are two versions of the application "HelloWorld": 1.0 and 1.1. (This is just an example)
I have installed HelloWorld 1.0 on my phone, and when I try to install HelloWorld 1.1, the 1.0 version will be replaced. But...I want to have both of them installed on my phone. That is to say, there will be two "HelloWorld" icons in the app drawer.
I use APKTool to extract the com.hello.world.apk into some "text" files, including an AndroidManifest.xml and a lot of *.smali files. In the AndroidManifest.xml, I saw this:
<manifest package="com.hello.world" versionCode="100" versionName="1.0">
I chaged the value "com.hello.world" to "com.goodbye.world". Then I re-build the apk file and transferred it to my phone.
I installed the modified package, it was successfully installed and I see two "HelloWorld" icons in my app drawer!
I try to launch the HelloWorld 1.0, it succeeds.
I try to launch the HelloWorld 1.1, it FCs immediately.
Well, this is my situation. How can I make both of them launch-able in my phone? Is it possible? What should I modify apart from "package" filed in AndroidManifest.xml?
Thanks a lot.

Well I'm not an android programmer but if I'm understanding you correctly you did the following (in the order I'm listing them):
1) Installed helloworld 1.1 (which over-wrote v1.0)
2) Opened the APK for helloworld 1.0 and made the manifest change
3) Installed the modded helloworld 1.0 on your phone
From a programmer point of view (just not with Android), if you followed the above scenario what is happening is HW1.1 installs it's files which are updated versions of the previous one (why else install an update). When you modded the HW1.0 you only changed the name and nothing else.
What is happening is when you go to install the modded version it's overwriting the newer files with the older ones since the phone is assuming the modded app is an entirely new program and allows the process to occur. This is why the modded one works and the 1.1 won't since the files it needs are the wrong version.
The only option of really have is to mod the actual program to look for different filenames, but without the source code to that app, that isn't going to happen.
Basically you need to have version 1.1 use the default files, and with the modded 1.0 you need to tell the software to "look" for the updated filenames (just don't forget to rename the actual files too).
Short of all that, as far as I know your SOL.

Great thanks to your reply. But...
Android uses .apk files to install and run the application. When installing an apk file, the package installer just copys the apk file to /data/app directory and "register" the program in the system. The apk itself will not be "extracted" or anything else. That is to say, an apk file can be installed, and also can be run.
On the other hand, the apk will generate some files in /data/data directory when running. I am considering that it was these file that made the modded version FCs. I will try to look into these files to see will this works...
English is my second language, hoping that I did not made many grammar misktaks...
+1 on this topic. It's been a year and a half since the last reply and I've done a bit of searching online to find no answers. I anyone have some feedback on this? I'd ultimately like to use this to install two Google voice applications. I actually have an app from a blacked out version with a different icon. But if I install it it will overwrite the original Google voice app

You are one hell of an archaeologist

I'd also like to know if that's possible. Even if it were possible, and an updated version of helloworld is relaeased (Say, HelloWorld v1.2), which version would it replace? Would it replace the (original) HelloWorld 1.1 or the (modded)HelloWorld 1.0?
Yes. Titanium backup. Profiles. These are the keywords.

It would replace the only legitimate version found, the unmodded one. The point of modding the APK is to make Android see it as a completely different app, and not think of one as an update to the other.

Hi
I would also like to do this for Google earth app I want to have both version 7.1.3 and 8.0.1 because the earlier version has more features but the latest looks more beautiful so I read the instructions from that link but it is way too complicated for a noob user like me plus judging from the last message it seems it hasn't been resolved so isn't there an app or xposed mod that does this automatically ?

[APP][PS4 Remote Play] over Mobile Network FIX

So I recently purchased a sony playstation 4 and thought to give it a go with remote play - downloaded from play market. From which I could quite easily connect to the playstation 4 with in my home wifi network (the app itself checks and denies a connection if the phone is not connected to wifi specifically.)
Hence no remote play over mobile network support via sonys official app.
This is where this thread came in http://forum.xda-developers.com/showthread.php?t=2929147
Read the 2nd post RE z3 phones.
Below I've quoted my post in that thread after my success with the port:
* Z3 Compact
* D5803
* Stock Xperia KitKat 4.4.4
* Unrooted & Locked Bootlaoder.
Simply uninstalled Remote Play which I initially had installed from Play market and then Installed your RemotePlayPortV0.6.1.apk (as per post#2 RE: Xperia Z22/Z3 devices.)
Subsequently successfully achieved your bypass of the dreaded WiFi check hindrance.. and can now Remote Play over 4G.

This is the apk I used from this original thread http://www.mediafire.com/?q4e4tgzzsmgmko1
If you got it Working (or Not) then please post with the below info:
Device Model Number
Rooted or not
Locked or Unlocked Bootlaoder
Android Version (4.4.2 4.4.4 5.0 and AOSP CyanogenMod Stock ect.)
--------------------------------------------------------
To anyone with Root on Stock ROM....
1. Does the official Sony remote play app deny you successful remote play feature given your rooted or does it still work?
2. Does the ported apk attahed in the above post achieve a successful remote play experience (which amongst other things removes the WiFi and Root check Sony had in place within the official remote play app found on market.)
3. Or do the xposed modules "Fake WiFi" & "Root Cloak" collectively make for the 'official remote play' app to work over 4g without need for the ported app?
--------------------------------------------------------
To anyone with Root on CUSTOM ROM...
1. Does the ported remote play app work for you?

There's not much interest here.
Regardless here's a tiny update on this regard.
I've since Rooted w/ Locked Bootloader.
On Stock 4.4.4 ROM.
For point 2 above just FYI for any readers out there - IT WORKS

how to upgrade the webview on my 5.1 phone?

Hi,
I am developing a hybrid app and would like some of the features of the newer version of webview. I check on the phone (Settings/Apps/All -> Android System WebView) and the stock version is version 39. I also note that the 'FORCE STOP' and 'DISABLE' buttons are inactive.
I installed the new version manually from the Google Play Store, and that is version 58.
If I list the packages using adb, I see that the old webview is com.android.webview while the newer one is com.google.android.webview.
So, now I have both versions installed, but I see from WebSettings.getUserAgentString() that my app is still using version 39.
Is there a way I can get my app to use the new webview?
Regards,
Max.
BTW, phone is vkworld f1 and not rooted.

Arcai netcut pro (free modified version)

Can someone confirm if this app works on rooted android 12, 13? There are more modded versions of it
Mod edit: 4pda link removed.
I'm using Dobradon one on android 8, works perfect, it has even more options than old wifi killer.
If their links don't work, I suggest you to try google and find those apk on other sites.
Also other similiar apps suggestions are welcome
