[IDEA] Xbox360 Controller for Android

Possible to make the Xbox360 controller connect to your Android phone ?
there's alot of software for both Mac and Windows letting you connect it to your computer, so without too much research i wondered if there is a possibility to port one of those apps over to android and use the controller for emulators and games.
there must be some open-source apps for win/osx out there i think so if any dev would have a look at it, for me to read those codes would be the same as to try to teach me greek..
just an idea, but if there's anyone that could make something out of this i think there will be alot of people wanting to use it
kinda like the SNES controller the streak's got, only wireless instead.. haha

Xbox 360 controllers aren't bluetooth
Sent from my HTC Droid Incredible. This Droid Does More.

its not just software to allow an Xbox controller to be connected to a PC, unless you're talking about the wired version, you need the reciever.
Like generamerica says, Xbox controllers aren't BT. PS3 ones are, but the bluetooth it uses is slightly different than normal and if i recall there have been issues in the past trying to get it to connect, no idea where that project has gone since then.
The only controller that can work with android from the big 3 atm is the wiimote, and even then you have to be running the stack from AOSP instead of the sense stack.

You got a lot of Bluetooth receivers !
It's possible !

!!!!!!! lo voglioooo contropper per android...cosi gioco a game psx gba

why not ps3 controller?

Yeah 360 would be impracticle if not impossible as you would have to either use a wired controller or have a wireless adapter for it to work. All of which means more stuff to lug around with an already large controller.
It would be cool to get the ps3 controller working on android but the controllerr is fairly big to carry with your phone.
Btw, the ps3 controller works great on windows. I use it with my netbook to play games in between classes. It connects to my normal Bluetooth receiver without any issues using a custom driver and software to pair the devices.
The only problem I can see coming from getting a ps3 controller working on android would be that once you pair the controller to the receiver you can no longer use it with any other devices unless you unpaid and uninstall driver to original. This is how it is with the controller on windows and most people use 2 Bluetooth receivers to deal with the problem.
Regardless of how practicle it would be to carry a ps3 or Xbox controller around with your phone it would be sweet to have working especially to get some of the other bluetooth controllers that are out there working. I have seen Asus controllers that are Bluetooth and have all the same buttons as ps3 controllers but they fold up and are a lot smaller and easy to carry around.
And a Bluetooth controller would be great for us who do not have enough hardware keys to play games with - no hardware keyboard.

Its hardly impractical, if you was chilling at work on a break and you and a friend wanted a game of street fighter on Tiger mame or something then i think linking two xbox pads to your phone and having a few round would be superb, I would avoid even bothering with wireless with the xbox pad because it's not bluetooth and the ps3 is problematic for most devices using sense (which means half of them) so it's just the wired xbox pad, a port or a fresh app which can link the onscreen buttons to games or emulators to the digital buttons would be fantastic.
Dev's would pick up on this and would probably develop around them if it became successful enough, I think it's a good idea, the reason i say that is because the onscreen keyboards for the devices out now have some achillies heel's on them, first one is the fact that it's touchscreen and it's just not the same as a pad, the second is there is only ever going to be one player per device the likes of street fighter 2 turbo and king of fighters were ment to be played with two players, not to mention the amount of other game types which would be played better on a pad other than touchscreen.
In an ideal world it would be a cable to your tv and a cable to your pad, run a game on your phone and play it on your tv with your xbox pad wired.
I know it can be done, might look into doing it myself, usb can be split too, analogue could come later, hmmmmm.

There is an actual implementation of Xbox360 controler for the Elocity A7 tablet,
[ROM] Emulator / XBox360 Controller Mod 1-21-2011
But idk if it could be adapted to other android devices since it seems to need an usb port support.

Yeah, in order to use the wired controller, you would need USB Host mode drivers, which at the moment not a lot of Android phones have (yet). At least, not to my knowledge anyway. Then you would need some sort of adapter to go from Mini/Micro USB (depending on which phone you have) to regular USB.

well I've seen some articles where people have some sort of adapter that turnes mini/micro usb into a dual input for (mouse / keyboard) so I guess two controllers shouldn't be that much further off... it's a matter of who has the knowledge and can implement it... unfortunately, it isn't me =( heh

But for the devices with usb ports how would one go about getting the required support in their rom?
When you plug the 360 controller in nothing happens.. I would like to know what files I may need to push to my android device that HAS full usb ports.

Get a micro usb to female usb cable, plug in the wireless adapter. Your device has to be running Android 4.0 to work, but it does work flawlessly. You then have to go to market and download a free app that allows you to configure the buttons on the controller....then you're all set. There are also a few games that are already set in options to run third party controllers as well. I'm planning on doing this as soon as we get some type on ICS love from any direction for the SGS2 SGH-T989, so. I hooked this setting up on a customers Galaxy Tab, so. Awesome...

This doesn't have to do with the xbox controller, but On my old itouch, I could use a wii controller to play games on a nes emulator. If it's possible with ios, then it has to be with android.

Well, maybe it's possible to make Android using pads already connected to PC? I have Xbox 360 pad with PC receiver and I am wondering if it's actually possible to connect that controller to Android device (mine is HTC Desire Z).
I'm afraid that there can be some input lag but maybe that can be done?

Plausible and an achievable concept... is it worth it? Lol?
This got me thinking.
I dont know why anyone would want to do this now a days but it is very possible.
Back in 2007 remotejoy came out on the psp-1001 Phat.
Basically the concept is simple you would put a couple of .prx files on the memory stick pro duo in the root directory in a folder named plugins. And set up a windows drivers and a small application I think. I'm not 100% about that but seems logical.
Then interface the psp with the pc via USB but before interfacing, you would have to go into the vsh menu which you would hit a button combo and a text overlay would appear over the xmb in the top left hand corner. You could then select what plugin you wanted to load. Then you would load up the prx's and plug in your controller and USB type B from the psp to the pc. It would detect it though libusb and then you simply execute remotejoy.exe "I think" don't quote me on any of this. It was a long time ago....
Then you would literally be able to play your game on your monitor or on a flat screen like me. Via dvi output from an ant 1600xt graphics card in crossfire. And my 10000 pound Sony professional 42 inch $4000 plasma..... and then thru remotejoy gui you could go to controllers and basically use any analog controller that there were drivers for...... Man things have really changed in 13 years!!!!.... Jeez.
These plugins could add all kinds of extra features. Fps counter, background music player, an ir yeah infrared.... lol irmanager a badass file explorer with every feature you could ever imagine, well there was an irshell .prx, and a psx one called pops before Sony ever even released it.....
Sound familiar? Should, first there was xposed framework, now we have magisk plugins with support for xposed modules....
With that being said this is very possible and a feasible feat. (Not that anyone should take it on).....
It was coded under unix. So same kernel we use on androids..... It could be forked/updated/shimed/referenced/converted/reverse engineer to remotejoy magisk plugin but it's old code.
I think the last time it was updated was in 09 when I graduated high school.... so someone way more talented then me could possibly modify and retrofit or port to android using adb and USB debugging on a rooted android.
But this is not my area of expertise ports aren't my bag, man.
It would be a huge undertaking.
For controller support it would use socks. TCP specifically.
I didn't dig into it too much because well everyone now a days has smart share or screen mirroring and bluetooth xbox one s controllers and 4k TV's......
Just wanted to say it it a very plausible and achievable project.
Sorry to dig up an old thread. I have the original source code somewhere.
Here's an excerpt for controller support and mapping via universal serial ports it's in raw.

[TOOL][APP][WIP] Native AT Command Injector

I trying to develop an application that can send AT commands directly to modem, from a native application interface (or possibly via terminal).
There are many obstacles here, but the main one is that the modem AT interface is rarely available through a simple serial device, which is why all other AT command apps always fail for the Samsung Galaxy class devices, which use a modified IPC protocol over sockets. However, by using the built-in RIL_OEM_HOOK_RAW and RIL_OEM_HOOK_STR we should be able to do this.
I then found this document for the Ublox LISA-U2 UMTS/HSPA voice and data modules, which show an example Android App, including most of the code used in that App. However, I cannot get this to compile in Eclipse. I think the reason is that there are many cosmetic changes in the AOS, while there are many typos in the code in that document.
I would very much like to get this or something very similar to work. I'm mainly developing on the Samsung Galaxy S2 (GB).
Here is a picture (from that document).

Any help with this would be very very much appreciated!
It will also benefit the rest of the community as it will provide a foundation
for my future development of many other things to come, for free!
BTW. The BP used in that device is the very popular Intel/Infineon XGOLD-626...

When trying to run the code shown below in Eclipse (using GB 2.3.3+),
it fails with the following errors:The import com.android.internal.telephony cannot be resolved

------------------ EDIT ---------------------
Of course they aren't recognized! They are internal packages not available outside the standard AOS API's. But I'm very stubborn and have now spent 2 days trying to use those damn packages anyway! I managed! I will post an update here and a whole new thread on how that is done, once I can get some other bugs out of the way...

new thread posted?

Here is my new thread on how to use and import internal packages into your project,
including instructions for hacking Eclipse ADT plugin, in order to allow for using
the com.android.internal classes.
"[APP][DEV][GUIDE] Using the Android Java Internal/Hidden API classes"
It is work in progress (WIP), and include a lot of manual file manipulations.
As such it is closely related to this thread. So keep an eye open for updates.
EDIT: 2014-01-06
That thread still work for API-17 JAR's!!

So, I managed to get it to compile but not without two main issues.
0) I got it to run on an SGS2 running GB2.3.4, but it FC's after being run.
1) I kept on getting AlertDialog builder complaints like:
"the constructor AlertDialog.Builder is undefined" so I had to comment out all code related to that. I searched for fixes, but since I'm not a Java programmer, I could not resolve this in the proper way...
2) Then I ran into some other undocumented errors from my own built (according to instructions) android.jar, so I just used the inazaruk's pre-made one, and it compiled. Here are his files:
https://github.com/inazaruk/android-sdk/tree/master/platforms
The main point is that we should not expect to blindly use the Ublox code and think it will work. Instead we need to understand the following:
a) How to properly use the RIL constants
Code:
[SIZE=2]RILConstants.java:
int RIL_REQUEST_OEM_HOOK_RAW = 59;
int RIL_REQUEST_OEM_HOOK_STRINGS = 60;
int RIL_UNSOL_OEM_HOOK_RAW = 1028;
my code:
EVENT_RIL_OEM_HOOK_CMDRAW_COMPLETE
EVENT_RIL_OEM_HOOK_CMDSTR_COMPLETE
EVENT_UNSOL_RIL_OEM_HOOK_RAW
EVENT_UNSOL_RIL_OEM_HOOK_STR
[/SIZE]
b) What the various bytecodes sent, are actually doing, and how to make them do what we want.
Code:
[SIZE=2] case R.id.radio_api1:
oemhook = new byte[1];
oemhook[0] = (byte)0xAA;
break;
case R.id.radio_api2:
oemhook = new byte[2];
oemhook[0] = (byte)0xBB;
oemhook[1] = (byte)0x55;
break;
case R.id.radio_api3:
//Send OEM notification (just echo the data bytes)
oemhook = new byte[7];
oemhook[0] = (byte)0xCC;
oemhook[1] = (byte)0x12;
oemhook[2] = (byte)0x34;
oemhook[3] = (byte)0x56;
oemhook[4] = (byte)0x78;
oemhook[5] = (byte)0x9A;
oemhook[6] = (byte)0xBC;
break;
[/SIZE]
c) If we can simplify the code to just send ONE hard-coded AT command and read the response.
d) alternatively use a completely different method, that will undoubtedly work, but will be device dependent. I'm talking about the (Samsung modified) IPC modem-communication protocols, as discussed in my older threads...
e) Find out how to use a local shell + device to send AT commands directly to BP.

To monitor the radio and related messages from the App (on a Sumsung) , you can use:
Code:
[SIZE=2]adb shell logcat AndroidRuntime:* ActivityManager:* dalvikvm:* DataRouter:E NetdConnector:D *:s
[/SIZE]

I've done similar work in my SprintDiagnostics app included in our Eos project. Its in the sprint gnex thread. There's no way to make this a user app as you have to be on the Phone looper thread. Meaning you have to declare the phone process in the manifest for the activity calling the raw ril requests. I can grab msl, write prl, and some other good stuff. And enable diagnostic mode based on shell work from Autoprime.

Hi! Thanks for interesting info, but unfortunately I don't understand all you're saying. But I got many more questions that answers.
First of all, what thread are you referring to? (Could you give a link?) Second, how do you do that declaration? (Code example?) BTW. I looked briefly at the code and must admit it seem a bit cryptic, as I didn't quite find the where AT's goes or are created. Third, what is "msl"? Do you have an APK to try on? Finally, what specific modem (cellular) processor are you running in that device? LTE?
Screenshots?
Thanks in advance.

Hi There
Forgive me if I'm oversimplifying it here but wouldn't minicom or some similar terminal program do this? I believe minicom is included in busybox.
Surely you could just wrap that around using JNI
AT Commands in android are sent natively by the vendor implemented ril library, normally set in global properties as rild.libpath. It may be worth stepping away from the JAVA code for a moment and looking at the rild and reference-ril sources in the aosp source. The atchannel.c is where the "magic" happens. Also If you haven't already, read PDK Telephony Documentation
When you get down to it, all you really want to do is read and write from a tty character device so doing it "raw" is always an option.
Also to monitor the Radio log in android use adb logcat -b radio , You will be enlightened as you watch the AT commands fly by!

No, you are missing the entire point of this thread. We are trying to circumvent actually using the vendor RIL, by tunneling the commands via the OEM_RAW requests. That is because it is often filtering out non-standard OEM AT commands that are not part of the common standard. These are all dependent on the BP/CP and and varies widely from device to device. In addition on many devices the direct modem serial is either not possible (because there is no such connection/transport) or it has been blocked/disabled. The Java way of circumventing this, is what this thread is all about. In addition the "-b radio" logcat doesn't fetch ATs sent by vendor specific OEM IPCs, for example. This is the case for the SGS2 (GT-I9100) and many other devices.

Well again... The point is that: RIL_OEM_HOOK_RAW and RIL_OEM_HOOK_STR are (internally) accessible for all RIL's. Which means that you CAN join in!

My apologies for not responding sooner. I forgot to subscribe ;( . I'd like to try and clear up my previous post as well as try to shed some light on this topic. First, I'm by no means a telephony expert. I've read some of your other threads and found them remarkable. I write Java and do feature development in a AOSP project. I currently am doing telephony work on Samsun Sprint CDMA devices including galaxy nexus, nexus s, and working on s3. As you know, those use the VIA chipset. However, working through the Android radio layer makes that irrelevant, for the most part. I've also worked with Autoprime on some telephony/modem/ril matters.
First some code and background on what I have done on Sprint Galaxy Nexus. These are some code fragments from my CDMATools app.
Manifest:
Code:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.teameos.settings.device"
android:sharedUserId="android.uid.system"
android:versionCode="1"
android:versionName="1.0" >
Of importance if the android.uid.system uid. This allows the app to access the phone process, which is required for PhoneFactory.getDefaultPhone(); The following activity queries ril for a Master Subsidy Lock code (msl)
Code:
<activity
android:name=".MslActivity"
android:label="@string/msl_activity"
android:process="com.android.phone" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
And the actual method which is used to query the radio...
Code:
private void checkMSLCode()
{
ByteArrayOutputStream bytearrayoutputstream;
DataOutputStream dataoutputstream;
bytearrayoutputstream = new ByteArrayOutputStream();
dataoutputstream = new DataOutputStream(bytearrayoutputstream);
try {
dataoutputstream.writeByte(main_cmd_hidden);
dataoutputstream.writeByte(OEM_SUB_CMD_GET_MSL);
dataoutputstream.writeShort(device_short);
if (isTuna) {
dataoutputstream.writeByte(OEM_SUB_RAW_MSL);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mPhone.invokeOemRilRequestRaw(bytearrayoutputstream.toByteArray(),
mHandler.obtainMessage(GET_MSL_DONE));
}
A snipit of the handler code to receive and process incoming messages from radio.
Code:
mHandler = new Handler() {
public void handleMessage(Message message) {
Log.i(LOG_TAG, "MSL response incoming!!");
AsyncResult asyncresult = (AsyncResult) message.obj;
if (asyncresult.exception != null)
{
Log.i(LOG_TAG, "AsyncResult Exception Occur!!!");
} else
if (asyncresult.result == null)
{
Log.i(LOG_TAG, "ar.result == NULL! - No answer for MSL response");
} else
{
byte abyte0[] = (byte[]) (byte[]) asyncresult.result;
String s = new String("");
for (int j = 0; j < 6; j++)
s = (new StringBuilder()).append(s).append((char) abyte0[j]).toString();
Intent intent = new Intent().setAction(getString(R.string.msl_action));
intent.putExtra(getString(R.string.msl_key), Integer.parseInt(s));
mContext.sendBroadcast(intent);
finish();
}
}
};
I have been able to get the raw commands from RE'ing various device proprietary apk's. Of importance to this topic is this checkMSLCode() function. This is the equivalent of raw AT commands, but being passed though the Android radio layer. From looking at the code for that AT command application you posted in the OP, it uses a similar structure. In fact, if time permits, i'm confident i can expand on it and make it somewhat more robust. One problem is see is finding an effective way to interpret the AT command responses from the radio. Requests often get a response in different forms, thus requiring a unique handler for each function. Of course, we could always do a Object.toString() to the log and try to decipher it. I hope this info sheds some light on the topic. I'll post when I come up with more.
Edit: also I should note, i build this apk inside of my AOSP repo, so it sees all the internal api automatically. I'm now looking at using reflection to do some telephony stuff, but it's proving rather tricky.

Very nice! (That was an understatement!)
I just wish I knew how to apply that...
Regarding the raw command (and their appropriate responses), I think there is both code and documents available for this, for Qualcomm chips. I know nothing about the VIA chipsets, but a whole lot more about the Qualcomm MSM stuff... Many CDMA devices use just Qualcomm, so perhaps you've been across some of these. I bet we could get this working on them, somehow.
Since, just as you said, the RIL should take care of much of the details. We just need to apply the command requests and responses. But my Java App making skills are really not even worthy a try at the moment.
Somebody else who'd care to join us, to give this a try?
As an aside and a note of reference, mostly to myself. (For a professional OEM programmer, this may be obvious, but me it's not. ) After having dug through some of the QC MSM code, I've come to the conclusion that QC like to use what they (?) call SMD (Shared memory Device) for doing their IPC stuff, which include talking to modem. While for Infineon/Intel modem, we know that Samsung have developed their own (non-standard) IPC protocol version for this communication...

While rewriting my Cdmatools app making it fragment based, I used reflection to access all the hidden apis. I'll fork the source for the at command app and apply the reflected classes.

I also got access to my Samsung Galaxy S3 via Reflection... although I had to go AOSP and sign with they same system key to run as looper. But now I just need help with what to send........ via RAW/String

Can you elaborate? Do you need info on what AT commands to send, or are you asking about the protocol?
PS. I would be great if you could say something more about how you did it, so that perhaps other interested people can join in. We need more people on this, so that we can start working on THIS project.

my apologies that i've been unable to continue efforts on that project. My aosp project consumes all of my development time and then some. Here is the source for CDMATools. I was looking for ways to monetize it. However, due to android's permissions scheme, it's not gonna happen lol. so here ya go.
www.miuimods.com/bigrushdog/CDMATools.tar.bz2
compile in eclipse then sign with aosp platorm test keys. I use some libraries that require it be compiled in eclipse. and because of the internal telephony imports, it must have the platform signature. Also, because it's compiled in eclipse, i use reflection to access internal telephony. Of interest will be the Phone service class. everything else is just ui. Look at how i structure the reflection. You can reflect all the internal telephony calls in the same fashion. any issues, just hit me. but my time now is very limited as I have a large team to manage and my plate is more than full. Good luck!
feel free to post on github, distribute, or whatever.

So I have not yet had time to modify OP app or using bigrushdog's CDMAtools. But I will soon. In the meantime I just post the internals for the _OEM_HOOK_ statements.
The code base is here:
https://android.googlesource.com/platform/frameworks/base.git/
So from the JellyBean RIL.java:
Code:
[SIZE=2]public void invokeOemRilRequestRaw(byte[] data, Message response) {
RILRequest rr = RILRequest.obtain(RIL_REQUEST_OEM_HOOK_RAW, response);
if (RILJ_LOGD) riljLog(rr.serialString() + "> " + requestToString(rr.mRequest)
+ "[" + IccUtils.bytesToHexString(data)
+ "]");
rr.mp.writeByteArray(data);
send(rr);
}
public void invokeOemRilRequestStrings(String[] strings, Message response) {
RILRequest rr = RILRequest.obtain(RIL_REQUEST_OEM_HOOK_STRINGS, response);
if (RILJ_LOGD) riljLog(rr.serialString() + "> " + requestToString(rr.mRequest));
rr.mp.writeStringArray(strings);
send(rr);
}[/SIZE]
And the expected response can be found in the ril.h:
Code:

The last one seem to imply that there could be other "bytes" to be read from that data[] array... Some suggestions have been the Transmitted power... But this was assuming a Qualcomm based modem, so there is no telling if there is another standard there. We don't know...

Here are links to two highly relevant threads on Gmane/GoogleGroups with code excerpts similar to what we need...

RasPiPhrase (Catchprase-like Code/RPiDevice)

This program is written in C and imports a few python scripts for LCD related actions(a few scripts provided by Adafruit). Basically, the program extends features of the classic Catchphrase Electronic game by allowing a variable number of categories and words for each. An overall synopsis of methods used to drive this program and device are posix threads, signals, PWM, gpio, multi-dimensional array allocation, unix directory commands, and more. Furthermore, the directory of word files is opened (each file formatted as "CATEGORY_.txt"), and the names of each text file (minus the underscore and extension) are loaded in as categories. Next, a three dimensional array is allocated to hold each category and its corresponding words loaded in as strings.
The code is thoroughly commented, and is hopefully understandable. The hardware used was an Adafruit LCD(i2c), four momentary push-button switches, Raspberry Pi, 3V (300-500Hz rated) buzzer, and enclosure (no rechargeable battery added because of the extra money involved but could easily be used as well). The rules are very similar to that of the normal game. During the timer sequence (~55s) when team-mates are guessing a word, pulse width modulation is used to simulate a 400Hz square wave with a 15s period and 50% duty cycle (calculation used to achieve this explained in code). This value is changed over the timer interval to increase the speed of the pulsing to indicate nearing the end of the sequence. Honestly, it probably would have been better to separate some of the functions into other modules, but I decided against it for this release for simplicity sake.
I hope this may be useful for someone interested in creating their own RasPiPhrase device. If you notice any bugs or issues please let me know and I will correct it. The necessary external libraries are wiringPi and python2.7-dev, the rest are a part of unix/C. A makefile that I wrote is included (in the attached zip) as well as all necessary code related files. Some example word files are included too, but you can drop in as many as you want and modify them however you want. The code takes care of the rest. This is the first version and has been tested, though not extensively. Let me know if you have any questions about the code. Enjoy!

[Q] app slow down when using sqlite database

I am trying to create a circular buffer using sqlite. For some reason every time I instantiate my db access class, the os start skipping frames (I am using the emulator to run my code).
02-22 20:22:03.172: I/Choreographer(860): Skipped 628 frames! The application may be doing too much work on its main thread.
I do not understand what I am doing wrong. I am calling the database class from an intentService (I assume this should not slow down the main thread at all) as follows:
Code:
private SqliteLog mSqliteLog;
mSqliteLog = new SqliteLog(context);
mSqliteLog.writelogInformation("sleepMode", "ON");
I added my code at the end of this message
Code:
/**

*
* Base class for sqliteLog control
*
*
*/
public class SqliteLog {
// Debug log tag

error: package com.google.android.maps does not exist

Hi,
i develop a map-app and want to implement google maps search
i get following build error
"error: package com.google.android.maps does not exist"
i develop under "android studio 3.1.3"
Hint for solution were appreciated
thanks

You need to add a reference to the maps package in build.gradle
Sent from my Z2_PRO using Tapatalk

i tested this https://stackoverflow.com/questions...le-android-maps-does-not-exist-android-studio
but without success

Can you post the content of your build.gradle file?

apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.tux.myapplication"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"

Apologies for the late reply, didn't get a notification from the thread.
Try removing the lines:
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.gmslay-services-maps:15.0.1
And add
implementation 'com.google.android.gmslay-services-maps:16.0.0'
If that doesn't work I'll draw up a demo app - this is a bit odd as I'm actually using maps in an app for my uni coursework and it's working fine
Edit: Also check that you have added the Google maven repo in the top level build.gradle file

hi,
i have still same error. i explained abov my purpose. i try this suggestion
https://stackoverflow.com/questions...ment-google-maps-search-by-address-in-android
and get this error.

and here is next purpose
https://stackoverflow.com/questions...-name-on-google-map-android?noredirect=1&lq=1
i don't know which one is better. i mean which one i can build without error.

hi jonny,
i have now a version it can work for me. but any thing is missed. can you pls add the missing parts.
thanks

briefly i will edit place name and move the camera. easy. but not for a newbie. pls support me.
