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.

Today I've installed Android Studio Canary 1
Now I cannot run my app. This following dialog appears.
I've already set the right SDK location through File-> Project Structure-> Android SDK location.
Expecting your help to solve this problem.
Warning Dialog image:
Go to project structure settings and set Source Compatibility and Target Compatibility to your current java development kit version:
Just you need to sync your project file with your gradle file.
File -> Sync Project with Gradle Files
I tried every answer in this post but my problem only got resolved when I made these steps:
File -> Close project -> Remove project -> Open existing project (same
project)
Maybe this will save a morning to another person with the same bug.
EDIT
This happened to me a lot on a MacBook. After I posted this answer it just kept happening so what I did was:
uninstall the Android Studio version I had from the App Store;
download the desktop stable version from Android Studio website;
start using the desktop version of Android Studio.
Never happened again.
Sometimes the SDK path will be incorrectly configured. You would need to fix it.
To Settings/Preferences( command + , on mac).
Search for SDK
Under Android SDK, click on edit and point it the root of sdk directory on your file system. (If ther is no SDk installed then install in from the below list).
i suggest you go to build.gradle and sync again.
Or Tools -> Android -> Sync Project with Gradle Files (Android 3+)
You need to insall SDK api 19 check this out.
https://developer.android.com/studio/releases/platforms
Go to sdk manager and install sdk according to your device and check your device api. Example if your device is jellybean then install api 19 sdk.
Go to Tools> Android > SDK Manager and make sure you have selected default Setting under System Setting. In this image I have selected Android 7.1.1 as default SDK
Just click on the button ..."Sync Project with gradle file"
Error will be remove
I had the same problem and what it worked for me was just sync with gradle.
I just did what I've found in this similar question:
How do I "select Android SDK" in Android Studio?
The original answer:
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.
Sync Project Icon
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
Before that, by the way, I had invalidated cache and restarted too, but it didn't work.
Please, try and let us know.
P.S.
I had this problem after I imported a project from Git, just in case someone would like to replicate.
I am not a dev, but have some dev experience. I have never used Android Studio before but I wanted to look at an example app. I picked one I am very interested in, but it gives me nothing but grief just trying to import it.
https://github.com/AltBeacon/android-beacon-library-reference
Notes:
I am using the latest version of Android Studio. (1.0.2). I have added in all the SDK files needed I think.
I have downloaded and un-zipped Gradle 2.2.1.
I am running Ubuntu 14.04.
I have dealt with Eclipse for Android previously and was able to
hack someone else's code to suit my needs and actually deploy an unsigned apk.
The readme/install directions at the github don't really help a noob
like me.
Install:
I have extracted the project from the Download Zip link.
For the actual import into Android Studio I choose "Open an Existing
Android Studio Project" - because it looks like one.
I then choose the root directory created by unzipping the zip file,
in this case it is named "android-beacon-library-reference-master".
But it seems to select the project's Gradle subfolder (/gradle) for the project! Which I'm quite certain is invalid. I cannot seem to get it to use the root
folder.
What am I missing? Or is this not the correct way to "import" this particular app? Is this app not compatible with AS 1.0.2?.
TIA!
In Android Studio, close any projects currently open. You should see the Welcome to Android Studio window.
1.Click Import Non-Android Studio project.
2.Locate the project you exported from Github, expand it, select the build.gradle file and click OK.
3.In the following dialog, leave Use gradle wrapper selected and click OK. (You do not need to specify the Gradle home.)
Android Studio properly updates the project structure and creates the appropriate Gradle build file.
Can you try "Import Project" instead "Open Project". Thanks.
All the questions dealing with this are now outdated. I am simply trying to open an existing Android Studio project.
I have cloned a repository for a project from http://blog.stylingandroid.com/material-part-2/
I have all the files, I choose "Open an existing android studio project" and then choose the "Material" folder which is the root directory of the project. When the project loads, it is called "gradle" and there are no files showing in the project frame.
I am using the latest version of android studio and the latest build tools as of 19 Dec 2014.
How do I import a project?
From the Android Studio welcome screen, try "Import Non-Android Studio project". It sounds like exactly what wouldn't work, but it does.
On 1.5.1, there's no Import Non-Android Studio project as the accepted answer says, but chosing Import project (Eclipse ADT, Gradle, etc.) does the trick. Open an existing Android Studio project does not work. Still quite weird.
Click on file, then click on Open. select the main file that contains the project's name without opening the file.
then Gradle loads but still nothing happens and the welcome screen is shown. press the combined keys of Alt+1 then the project files will appear on the left side of the screen.
Sometimes it is tricky to open Android project. My tip is try to use
File -> Open... -> <path_to_settings.gradle>
I was working on an android tutorial and it wanted me to import the library from another project .The import worked and the project works correctly. But I noticed that doing that messed up several of my other projects (the ones that use Android 2.1) by apparently messing with the build path. Now instead of seeing "Google APIs [Android 2.1]" under the gen folder I see "Unable to get system library for project".
I verified the following:
I right-clicked the project and went to Properties I see that the correct Project Build Target is checked(Google APIs [Android 2.1]), but "Unable to get system library for project" is still shown above the assets folder and below gen and Android Dependencies. Cleaning all projects doesn't help.
How can I fix this problem?
is there a way to fix this issue globally or do I have to do it one by one?
I had the same problem. Try
Right click on your project
Go to properties
Click the Android section
Select a different target api (assuming one is already selected, as mine was - otherwise, select the one you want and jump to step 9)
Click OK
Do steps 1-3 again
Select your original target api
Click OK
Clean and build your project
Worked for me, anyway.
Derived the solution from:
"Unable to get system library for project" after I upgraded to Android SDK 2.3 and ADT 8.0
Error in .classpath on your project. It not connect to android sdk. Fix it and clean project. :-)
This happens when you are targetting an API version that for some reason is not mapped on your buildpath.
See which is the version of the SDK you are pointing to at the project.properties file.
Go to the SDK Manager at Window->Android SDK Manager
Check the Android API item that matches the version you want to use, OR, click on the latest one and then update your project.properties file.
Make sure your project build configuration is Project->"Build Automatically"
Retsart Eclipse (claning and rebuilding may not refresh all the project properties)
Borrowing from #Erhannis answer :
"
Right click on your project
Go to properties
Click the Android section
"
When I view the build target everything looked fine :
So I checked another build target , hit apply, and then re checked my original build target (Android 4.4.2) and re-hit apply. My project then compiled.
For me the project.properties file was missing (it was code from a repo I checked out). So I just created one with this line:
target=android-20
After that, Erhannis' solution worked for me.
Just for completing Erhannis answer: If you fixed the problem but it appears again when you restart Eclipse, then just go to the file local.properties on your workspace folder and verify that the location of the Android SDK there is correct.
At times, when only single Android SDK version is installed on your system, and if it gets changed either by un-installing / re-installing Eclipse, or otherwise (directly through SDK Manager), then this issue might crop up.
.
This is accompanied by the message like this on Eclipse console:
YourApp] Unable to resolve target 'android-22'
.
A simple workaround to this issue is:
Open AndroidManifests.xml of the project, and in the:
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="21" />
change the targetSdkVersion to the one currently installed on your system
Next, open the project.properties file and update
target=android-21
to your current SDK version
Finally, clean and re-build the project
Right Click on Project-> Select Android tools -> Select Fix Project Properties
This did the trick for me.
You need to click on the menu icon with the Android sitting in the grey box with a white arrow pointing down "Opens the Android SDK Manager".
or, from the command line, run:
%ANDROID_HOME%\tools\android sdk

In the project root folder you should have file named project.properties
---- file content -----
target=android-16 ## <--- make sure that it is there and that you have proper sdk installed
For me, the problem was that in the Project settings - Android tab, I had no Android version selected.
For me I had SDK version 8 selcted, but if I selected the next highest version, applied, then selected version 8 again and apply, fixed the problem.
For me, what worked was to restart Eclipse. Hope this helps.
