I have SDK version 25, when i import a project in android studio this error occurs.
"Install missing platform(s) and sync project".
If I click this link, I get another error, which says:
"The following packages are not available: - Package id
platforms;android-23".
sdk error
my SDK version
You need to change the gradle version manually. For example if you are using Android Studio here is how:
Change the project view to Android if it's needed.
Go to the app folder.
Open the build.gradle (Module:app).
Change wherever you see the current SDK version (here, 23) to your desired version (here, 25).
5. Sync the project again.
And it's done.
Note that if you forgot anything needed the change, Android Studio will display a message and change it automatically.
Your sdk platforms are missing. It must be from version 2.1 to 8.0. Try to reinstall your Studio and Sdk Manager.
Note: This only works if you are getting sdk issue in a particular project and other project works fine
One of the simplest fix I can suggest that worked for me
create a new android project and see if it works fine
If yes the Click File-->Export Settings(make sure to check all options) --->choose any location to save settings.
Go back to your project click File-->Import Settings from the saved location (make sure you select all options)
let the IDE Restart
Hope this fixes the issue
I am using Android Studio 1.5.1 on windows 7 .I am not able to find the rebuild or clean option under the "Build" option?Is there any command to force rebuild or do it form the Android GUI?
The project was built in Eclipse and I have imported it in Android Studio.Earlier I was getting some error from google Play services which I have resolved by commenting the below line in the project.properties
target is android-23
android.library.reference.1=../../../../workspace/google-play-services_lib
Maybe there is something that you need to update before continuing to develop your project. Check on Help -> Check for Updates...
You should always keep Android Support Repository, Google Play Services, Google Repository, Android SDK Tools and Android SDK Platform-Tools updated.
I also encountered this problem and my Android studio was also latest version. As a workaround for this problem what I did was to open the module settings and changed values and reverted back to old values and click ok. After that those missing menu items appeared.
After downloading Android Studio and opening an existing project, when I went to edit configuration (after trying to run an existing project) but when I attempted to configure it as an Android Application, I did not find the android application option, which when I compared to my other computer, is required to run the program.
Furthermore, I am missing the Android SDK Manager, both in the IDE and on the startup screen. I don't have SDKs installed on this computer, and I think they are needed to run my project, so I kind of want the SDK Manager.
I have also re-installed Android Studio 8 times, including several older versions. I also installed the packages, which do come with SDK tools, and I made sure everything was selected on installation.
In my case it helps: just File -> invalidate caches/Restart
hope it also can be usefull to someone ;-)
check the sdk manager present in the location "C:\Users\"user-name"\AppData\Local\Android\sdk"
launch the SDK manager install the package that you needed
paste the link
"C:\Users\"user-name"\AppData\Local\Android\sdk"
[Android Studio>configure>Settings>Android SDK ]
Maybe try deleting everything of Android Studio and then installing the latest version. It might be because of the leftovers of the previous versions that caused this problem to occur. The best way is to try restoring your PC to the time you hadn't have Android Studio.
Click on File -> Sync Project with Gradle Files
After a successful import of an Eclipse-Android-Project into "Android Studio 1.4", I get the error
"Please select Android SDK"
when I click on the button to run the application in the simulator, I can't find any way of doing that.
This dialog opens when I click on "run":
This is the "project structure" dialog:
What should I do now?
I go to build.gradle and click sync now. Then it worked.
Update :
File -> Sync Project with Gradle Files (Android Studio 3.1.1)
Tools -> Android -> Sync Project with Gradle Files (Android Studio 3.0.1)
Or You can click on the icon from the toolbar.
This answer may not help works for later version as Android studio Team work on making the tool more better, the way to sync may be different in the next version of Android Studio.
COMMON WAY that may helps is try to sync project and then Invalidate Caches and Restart Android Studio.
Solution for Android Studio 3.1.2 [See below answer]
See Latest Android Studio version
FIX FOR 3.1.2 OR NEWER VERSIONS
Some of my colleagues and I have faced the same issue on AS 3.1.2, but a simple Sync didn't help us. For us, the solution was a bit different:
File -> Invalidate Caches -> Invalidate
File -> Close Project.
Remove the project from the AS project selector window.
Quit from Android Studio
Start AS and open project again
EXTRA ADVICE IF YOU ARE FACING THIS ISSUE CONSTANTLY
Some of you are constantly facing this issue, and this "solution" fixes it only temporarily. At the time we started getting this error, we used gradle wrapper 4.6 and Android gradle plugin 3.1.0, but since then we went back to gradle 4.4 and we use it with the latest Android gradle plugin, and we haven't seen this issue since then.
In Android Studio 3 and above, for Windows, Mac and Linux:
File -> Sync Project with Gradle Files
Solved!
Or you can do this by shortcut key:
Press ⌘ + Shift + A (Mac) or Ctrl + Shift + A (Windows, Linux). Then pop-up a Edit-Text and write "Sync Project with Gradle Files". Then press double click on the option.
Your problem is solved! It'll sync your gradle file with your project file.
Screenshot:
Click this icon to sync gradle
or edit any of your module gradle and then sync
Press "Ctrl+shift+A" and in the pop-up EditText, write "Sync Project with Gradle Files". After that double click on the appeared option. It will then sync your Gradle file SDK with the project file.
Just go to the (app level) build.gradle file, give an empty space somewhere and click on sync, once gradle shows sync complete then the Error will be gone
This is the easiest way to fix this issue:
Add a comment line to the gradle file
It will then ask you to Sync.
Click 'Sync Now'
Viola! You're done.
Now on Android Studio 3 and above, you can try to sync project with gradle like:
File -> Sync Project with Gradle Files
The menu structure and options have changed slightly as of Android 3.2.0. I fixed this error by changing the Module SDK in the following menu:
File > Project Structure > Modules > App File > Dependencies Tab > Module SDK
Make sure to hit Apply to save your changes.
The comment from #Nisarg helped: "set latest version in Compile Sdk Version"
I changed from API 8 to API 23 and the error message disappeared.
Press the first refresh button on the gradle vertical tab in Android Studio on the right
Press " ⌘ + Shift + A" on Mac (or "Ctrl+Shift+A" on Windows) and in the pop-up EditText, write "Sync Project with Gradle Files". After that double click on the appeared option. It will then sync your Gradle file SDK with the project file.
Follow these steps:
Goto Android Studio Settings
Search for "Android SDK" using search bar
Ensure the path to your android sdk folder is correct.
After that also ensure the path is automatically updated after a prompt in your project (local.properties) file. If not, do it manually.
Hope this helps.
There are multiple hit & trial solutions for this error. One of them will surely work for you.
Below are the solutions:
1.
Tools -> Android -> Sync Project with Gradle Files (Android Studio
3.0.1)
Go to build.gradle and click sync now
Click hammer(Build) icon to sync Gradle
or edit any of your module Gradle and then sync
File -> Settings -> Android SDK -> Android SDK Location Edit ->
Android SDK
Open build.gradle file, just add a space or press enter. Then sync
project.
File -> Invalidate Caches / Restart
Go to File >> ProjectStructure(⌘;). This would open this window then select the app module. Then choose the Compile SDK version . Choose the latest one and click apply.
I was having this problem on all versions of AS 3.0+. Syncing with gradle did not solve the problem for me. The solution from András Klöczl was the only thing that would allow me to get some coding done. The problem was, anytime I had to do a gradle sync, the problem came back. So I had to go through that process any time I wanted to make a change in my build.gradle. What ended up working for me was to downgrade my kotlin version from 1.2.40 to 1.2.30
My problem was that if I changed the project (for example opened new window of Android Studio with different project) this error happened.
So I read every answer in this question and the "clear caches and open the project again" solution wasn't so useful in my case.
Instead I discovered that if the Kotlin's plugin's version in Android Studio was lower than in gradle file, the problem appeared.
My setup was:
Android Studio 3.1.3
Kotlin plugin (in Android Studio) 1.2.30
Kotlin version in gradle file 1.2.51
What fixed the problem?
I updated the Kotlin plugin:
File -> Settings -> Plugins -> Install JetBrains plugin...
Then search for Kotlin and click Update. After update just restart the Android Studio and sync Gradle.
Just change build tools version to 25.0.3.. and sync now
I hope it will help..
This worked for me.
File -> Settings -> Android SDK -> Android SDK Location Edit -> Android SDK
Go to : File > Project Structure > Modules -> app > Properties
please choose : Compile 'SDK' version = API26 Build Tools
Version = 27.0.0 Source Compatibility = 1.8 Target Compatibility =
1.8
open build.gradle file. just add a space or press enter. then sync project. it works...
Sometimes android studio just acts stupid and needs some kind of reset..
Go to settings.gradle file it should contain include ':app'
change it to include ':ap' and sync.
after sync, change it to include ':app' again.
It should be working OK now.
The simplest solution for this problem:
First make sure your sdk path is currect.
Then
Please close current project and in android startup menu click on import project and choose your project from explorer.
This will always solve my problem
In my case there there is no selected java sdk version in project structure-
I had to select the -
1.Source Compatibility (1.7)
2.Target Compatibility (1.7)
as shown in image.
If you are using 'Profile or Debug APK...', then you might come across this error.
My solution is to first check SDK for updates in SDK manager: click on "Edit" at the right side of SDK location and go through to install any updates:
Then I clicked on "Logcat" at bottom of Android Studio and find out I also need to configure Android SDK, so choose latest Android API Platform:
After that, I'm able to run the APK in Emulator.
In latest android studio 3.3.2 the icon of sync project with Gradle Files is changed
Now try this
File -> Sync Project with Gradle Files (Android Studio 3.3.2)
For Android Studio 3.5, "File -> Sync project with gradle files" is enough.
Go to gradle.build file and click sync now
OR
click icon on Sync project with Gradle file
OR
Go to Tools-> Android -> Sync project with Gradle file
If your android SDK path is given and still you facing this issue then it might because your android studio not synced well, even you have clicked on "Sync now" link.
So for re sync it go to app gradle file and make any change or just give a space and now sync again. It will work perfectly.
In my case I downloaded a git repository for an android project. The project required minimum sdk version 21 and target sdk version 27. When I tried to run the project it gave me "Please select Android SDK error". I checked that I had already downloaded the required sdk files.
For me the solution was to "sync project with Gradle Files"
I have created a new project using the latest version of Android Studio (0.2.2), this is a fresh install of studio. When I am in the project explorer view, it fails to show me any folders for my project. I should see a root project folder, and within it the .idea, gradle, and module folders, but they are not showing.
Here is what I expect to see (taken from the sample project created on first boot):
But here is what I see immediately after the project's creation:
I cannot figure out how to expose my project's folders! I do not want to develop without the project explorer, it's simply too much of a hassle. Did I create the project incorrectly, or am I missing some not-so-obvious setting somewhere?
Thanks.
The problem here is that I assumed android studio would create a module for the application. I assumed this because it asked me at the beginning for app name, module name, package, sdk info etc.
This assumption turned out to be false. You must create your first module manually through File > Project Structure. After that is done, the project explorer shows the files.
File -> Project Structure -> Modules
Add Button (Green plus button) click -> New Module Select
New Module window -> "Content root" change path button click to select "Project root file path"
Apply to change save and "OK" button exit.
In the project Explorer there is a drop down menu where you have selected project, now change it to project files.
I hope this will solve your problem. reply if it didn't.
You have created a new gradle project not a new android project.
Update your android studio tools to 0.2.3 - Go to Help menu - select check for update.
then Update your android sdk tools, android support repository, android support library and android build tools using android sdk manager.
And update some configuration in project structure. Go to File menu->project structure -> in projects tab select Android SDK as default sdk and in SDKs tab set correct path to updated android sdk.
Now restart android studio and try to create a new project and it should work fine.
(Noted for posterity) I had a similar issue come up recently, when importing an Eclipse android project. The issue was that the source folder wasn't added as such. I had to manually go into Project Structure -> Modules -> Sources and make sure that the "src" folder wasn't excluded and was marked a source folder.
Although this question is asked years ago. But now following simple solution worked for me.
Clicking 'Sync Project With Gradle files' makes all directories visible.
I had this exact same issue, there are some problem if you upgrade from 0.1.9 version to 0.2.0 in Windows.
Android Studio 0.2.0 Release
The solution (which worked for me) was to completely uninstall Android Studio and reinstall the 0.2.0 version.
I had the same problem today. Additionally, the IDE posted an "Assertion Error" into its event log.
Downloading and reinstalling the preview version, then applying the patch to 0.2.6 worked for me.
Change the SDK to a level that you have installed in the SDK manager. The SDK manager can be accessed from Tools -> Android -> SDK Manager. For me, Android Studio was packaged with API Level 17 but the new project wizard tried to target API Level 18.
