I am trying to import GSON into my project using gradle in android studio. I have used instructions found on google'sGitHub and several stack overflow pages, such as here. However when I go to import into my file using the line
import com.google.gson.Gson;
I still get the following error
Error:(5, 23) error: package com.google.gson does not exist
example from my app's build.gradle
compile 'com.google.code.gson:gson:2.7'
and my settings.gradle
include 'gson:2.7'
Am I missing something?
Open your project. Go to File -> Project Structure...
Click on app in the Modules section and switch to the Dependencies tab. Click on the plus icon in the top right corner and select Library dependency. Select the entry for the GSON library from the list and hit OK twice. (Note: the search bar didn't work for me)
Then you are able to use the library just like you described in your question:
import com.google.gson.Gson;
Note that after adding the library your project will do a gradle sync which may take a couple of minutes.
The dependency should be imported properly after syncing your project.
Try selecting Sync Project with Gradle Files in the upper right corner of Android Studio (referring to the default layout of Bumblebee).

I'm trying to integrate Google Calendar API into my android project and I follow the tutorial here
https://developers.google.com/google-apps/calendar/quickstart/android
At step 5 create a new java class
I right click project folder src>main>java>com>example>utarapp and then new>file and entered the file name but then it has this error
What's going on ?
I'm using android studio 1.3.1
I think you are trying to create file with same name which is already present in the same package. This may be one possible reason.
It seems like you are right-clicking on the upper level in your application's directory tree.
Right click on one of the files inside the utarapp folder and then select Java class option from the menu.
For me this was happenning because of the length of the class name. In my case it was "ChallengesFragmentPagerAdapter"!
Changing it to "ChallengesPagerAdapter" solved the problem.
Create a blank Activity then remove "extends Activity" from the activity class.
Opening a VB6 Project, I get errors like:
Errors during load. Refer to xyz.LOG
I open the log file and see these errors:
Line 42: Class Threed.SSPanel of control XYZ was not a loaded control
class.
In this case I can see the problem is due to the Sheridan 3D Controls: C:\WINDOWS\system32\THREED32.OCX
I thought the project was missing a component so, VB6 > Project > Components > tick the Sheridan 3D Controls and got this error:
---------------------- Microsoft Visual Basic ---------------------------
Name conflicts with existing module, project, or object library
--------------------------- OK Help ---------------------------
I will give you the best way to get rid of this problem. I came across many ways, but this is the most best way to deal with..
Close the project. Right click on the vb project and open with notepad (not with vb). This Project file will only consist of all the references, libraries and information about forms and modules used in the project.
Now just remove the conflicting module or component file, you have problem, by just deleting the entire line.. Save and close it
and now open the project and add component. I swear you wont get that error.
Thank you. Enjoy
The way to troubleshoot this problem is to start a new VB6 project > Project Menu Components > tick the Components that are selected in the affected project until you get the error.
---------------------- Microsoft Visual Basic ---------------------------
Name conflicts with existing module, project, or object library
--------------------------- OK Help ---------------------------
You need to narrow it down to the two OCX's that are conflicting.
In my case I narrowed it down to Sheridan 3D Controls / THREED32.OCX and Outrider Spin Control / SPIN32.ocx
To fix the problem I used RegSvr32 to unregister the OCXs - make sure you UNregister with the /u flag.
REGSVR32 "C:\WINDOWS\system32\THREED32.OCX" /u
I then copied the OCX's to the project folder and registered them again using:
REGSVR32 "C:\Dev\Project\THREED32.OCX"
Then in the project with the problem > Project Menu Components > select the item in the listbox Sheridan 3D controls / THREED32.ocx (you cant tick without getting the error or untick the conflicting one that is selected as its in use) > click Browse and reference it from the project folder rather than C:\WINDOWS\system32\
Another trick is close the project and unregister the affected ocx - make sure you UNregister it with the /u flag, eg
RegSvr32 "c:\Windows\system32\mscomctl.ocx" /u
Then open the project > Components > and you should see the "Microsoft Windows Common Controls 6.0 (SP6)" is using a OCX file in C:...\Microsoft Vi..\VB98\mscomctl.ocx" rather than c:\Windows\system32\mscomctl.ocx.
The project should then load without these errors:
Errors during load. Refer to xyz.LOG
Try unchecking the latest object library / reference from the references and check it again and then go for your desired reference (vb6 has few bugs which can be countered by a reverse process). I solved the error mentioned using this process.
(Noob alert!)
I want to add an SQLite component to a simple (one Java source file) app and would like to put it in a separate file. I was hoping to find something that would let me click a couple check boxes and creae the file using a template with the standard overrides and class declarations (e.g. ... MyClass extends SQLiteOpenHelper {...} and so on. Instead I can't even figure out how to add an empty .java file to the project. Google's Android Studio Tips 'n Tricks suggest navigating to the 'appropriate directory in the Project pane' and hit N. That gets me a dialogue that rejects my class name and seems to open a header file if I enter the name if the class I wish to extend (and without apparently adding anything to my project.)
I do not even see a way to add an existing file to the project. OK... I now see that if I create the .java file in the app directory (along side the MainActivity.java file) that Android Studio automatically includes it.
Is this Standard Operating Procedure? It leaves me feeling like I'm not leveraging the capabilities that Android Studio provides.
I'm using AS 0.5.2, openJDK 1.7.0
Thanks!`
If you're creating a new Java class from the Project pane, you don't need to add the ".java" to the name; you're specifying the name of the Java class, not the source file. It will figure out the filename automatically.
Working in min API 15, I'm trying to find how I can drag and drop one item element out of a ListView list onto a TextView above it (just to copy the text into it).
I'm trying to follow this example:
http://techdroid.kbeanie.com/2011/10/drag-and-drop-honeycombics.html
Namely these two parts...
http://code.google.com/p/myandroidwidgets/source/browse/trunk/HCDragDrop/src/com/beanie/hcsample/dragdrop/MyDragShadowBuilder.java
http://code.google.com/p/myandroidwidgets/source/browse/trunk/HCDragDrop/src/com/beanie/hcsample/dragdrop/HCDragDropActivity.java
However, I can't figure out how to fix this error
The import android.view.View.DragShadowBuilder cannot be resolved
Or if I remove the import then DragShadowBuilder gives me
DragShadowBuilder cannot be resolved to a type
I changed my minSDK And target SDK both to '15'. Should I not have access to these classes now? How can I resolve this error?
edit: I've fixed that problem- properties, android, set target. Clean, refresh. Ok.
But now I'm getting
btn_default_pressed cannot be resolved or is not a field
on
mShadow = v.getResources().getDrawable(R.drawable.btn_default_pressed);
Looks like that class came in API 11. So probably you have one of a couple problems.
You have set the SDK target in your manifest, but you haven't updated your actual SDK. If this is the case, go to the SDK Manager and get the necessary updates.
You project is still linked to a API 10 or lower jar. If this is the case go into, Project > Properties > Android and pick the correct library.
Project > Clean and restarting Eclipse can't hurt either.
Hi I have a problem with the ActionBarSherlock after importing.
I made the following steps:
I Imported the stuff from the library folder
I checked if the project is set as IsLibrary
I selected Project Build target: Android 4.0
then the project look like this:
I dont know whats wrong, the error in the first package e.g. is:
The method onCreatePanelMenu(int, Menu) of type Watson must override a superclass method
ActionBarSherlock library is full of errors after being imported
There May be other ways, My Suggestion is to go to java file and remove all #override symbols above the methods there, because I have also faced that problem and I did that to get rid of those errors! I think this may meet your need.
