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 am building a project with Cordova for iOS and Android platforms (cordova version 7.0.1 and platform iOS 4.5.1 and platform android 6.2.3). When I use the command cordova run ios or cordova run android I find that the iOS build will somehow not have embedded cordova.js and although the pages will load, none of my cordova plugins will work and the debugger shows the following error:
exception nativeEvalAndFetch : ReferenceError: Can't find variable: cordova
If I manually include <script type="text/javascript" src="cordova.js"></script> in my index.html file and run the command again, everything works fine (although then android complains of a second declaration of cordova.js)
I would like to have one build where I don't have to constantly modify one or the other environment. Here are some other things I have noticed when running those commands:
I have verified that the index.html and three js files (app, manifest and vendor) are identical between their iOS and Android generated versions (in /platforms/ios/www and /platforms/android/assets/www respectively).
Also the other files present in each folder seem to match.
Because the appropriate files seem to match, I believe this bug is at the point where the command loads the bundle/app onto my iPhone or simulator, and as I said plugins will not work without force including it in the index.html file, but everything outside of plugins works fine in the app.
I seem to be having an issue with all Cordova plugins that I am adding to my project. For this question, I will reference specifically the SplashScreen plugin.
The process that I take when building my project for IOS is as follows:
ionic cordova platform add ios
ionoc cordova prepare ios
ionic cordova build ios
At this point, the build will fail with an error 65 on xcode args. After some googling, I found that a solution to this is to perform ionic cordova platform update ios, this fixes the problem and allows me to compile and run my application, yay!
The reason that I have included the above details is, I am worried that perhaps updating the platform is for some reason causing the plugins not to load / be included. Just a thought but thought I would include that process for reference.
When running my project in the IOS emulator on mac, I get the following plugin errors in the console for xCode, this error message is specifically for the StatusBar but is the same for all other plugins I have added:
2017-08-13 20:41:36.391 Shokuni[20906:1123728] CDVPlugin class CDVStatusBar (pluginName: statusbar) does not exist.
The plugins then reset due to page load…
2017-08-13 20:41:37.724 Shokuni[20906:1123728] Resetting plugins due to page load.
Then i get the following error about the status bar, which I assume is because it is being attempted to be used on the first page loaded in the project
2017-08-13 20:41:38.883 Shokuni[20906:1123728] CDVPlugin class CDVStatusBar (pluginName: StatusBar) does not exist.
2017-08-13 20:41:38.883 Shokuni[20906:1123728] ERROR: Plugin 'StatusBar' not found, or is not a CDVPlugin. Check your plugin mapping in config.xml.
Inside xCode, in the File Explorer panel on the left, there are no plugins inside the plugin folder, I am wondering whether this could potentially be an issue? I can however see that the plugins that I have installed are available at staging/www/plugins
Anybody had this problem before or knows about what may be going on? If so I would be very grateful.
Hey, Guys! I recently started to work with Cordova and when I run the Cordova platform add android i get the following error. I have successfully placed the environment variables for Java and for the Android SDK as well. But the npm modules does not exist in C:/Windows/System32/npm as shown in the error, It is in the Users/My username/AppData/Roaming/npm folder. Some guidance would be appreciated.
I followed the following scripts which are shown in the official Cordova documentation to create a new project.
Cordova create hello com.example.hello HelloWorld
cd hello
Cordova platform add android -> where I'm stuck at
Kindly Check the Android Version Provided by Cordova and verify with your current Android version installed on your system , if there a mismatch :
1) Update Android Version From Android Studio SDK Manager
2) Update Cordova Platform - Refer: Cordova Documentation
External Source
cordova - Error: Failed to fetch platform android
I figured out halfway what the the problem was. There was a file named 'npm' in my C:/Windows/System32 directory wich was of 0kb size, and once i deleted it, the error vanished. But not all the way though. I was able to install the browser platform but not the android platform via cordova platform add android or even specifying what the matching cordova-andriod pluggin to be with cordova platform add andriod#version.
Only through the cordova platform add https://github.com/apache/cordova-android.git script I could install the andriod platform and once it was done other steps worked fine, and the project ran through the Android AVD. Any idea why the normal command to add the android platform didnt work, Just want to know but if it happens again i think Im gonna have to run the get from git command again. Thanks
Hello I downloaded and installed node.js as I have done million times also I installed cordova as mentioned in their docs. Furthermore I installed console.plugin with "cordova plugin add org.apache.cordova.console". Finally I did cordova build android and the cordova emulate android, and inside www/js/index.js onDeviceReady I simply entered this console.log('test');
I'm new with cordova and I cant figure out why I dont see and output in my terminal.
PS: I'm on ubuntu 12.04 LTS 64bit, and I dont use eclipse. Shouldn't I see the console.log output in my terminal window ?
From the CLI run your Android project and display console output from chromium (if using Crosswalk) or SystemWebViewClient. View Debugging priority and above logs from these places, and silence everything else.
cordova run android && adb logcat chromium:D SystemWebViewClient:D *:S
Using alert() is a rather dilettantish debug methodology. The most simple is to use a hardware device or an emulator with adb and chrome://inspect. This provides the debug bridge for the Cordova WebView, as well as the JS console, JS debugger, DOM inspector, etc. within Chrome.
See Get Started with Remote Debugging Android Devices.
The output will appear in an output window, not in the terminal window.
I run my Android Cordova apps in Eclipse and logs appear in the Logcat output window, similarly with iOS apps and Xcode, they appear in the Xcode output window.
You could always just alert() or navigator.notification.alert() to quickly see your logged values.
Hope this helps.
