when I have these imports in my code or use any of the classes and and methods, I get this error from intelli J IDE.
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.ObjectMapper;
Class 'com.fasterxml.jackson.databind.ObjectMapper' is not included in App Engine JRE White List
this does not result in any Maven build errors but or any errors in production. but why is the IDE flagging the error.
Class 'com.fasterxml.jackson.core.type.TypeReference' is not included in App Engine JRE White List
Those imports aren't part of the Java Application Programming Interface (Java API)
They are library that are created and in order for you to use them, you have to download and add the jar file in your java build path library
I am trying to create a Bluetooth application in Android Studio. I am using BluetoothGatt.java which requires IBluetoothGatt.java which is not in the sources folder in my android studio install.
I downloaded IBluetoothGatt.java from grepcode and saved it in the sources folder (where BluetoothGatt.java is located) but when I try to import IBluetooth.java it can't find it.
Is there a step I'm missing? I've never done anything like this before so I'm not familiar with how to import a downloaded file into my project.

It seems that Eclipse cannot find the third party libraries being used by the app even though I see them all in the libs folder under the package.For example, it cannot find the Crittercism, Google Analytics or Parse libraries. The import statements below all show a red X and when I click on the prompt to fix the import links, it says I have to do it manually:
import com.crittercism.app.Crittercism;
import com.google.analytics.tracking.android.EasyTracker;
import com.google.analytics.tracking.android.MapBuilder;
import com.parse.ParseException;
import com.parse.ParseObject;
import com.parse.ParseQuery;
My question is, how do I force Eclipse to look in the right folder, assuming it is not looking in the right place for the libraries. This is working source code from the developer which we used to create the apk and upload it to the Google Play Store, so I assume there is no issue with the code, but more so in the way the project is configured in Eclipse.
Basic thing you can do is clean/build the project Project>Clean (Refer Image : http://i.stack.imgur.com/T9ihk.png) and check if the things fixed
Check the necessary jars are available in libs folder of you project root.
Check if the neccessary jars are properly added to buildpath. Right click your project > click on Properties (Refer Image : http://i.stack.imgur.com/A6xgq.png). If you see it highlight with red then you can remove it and follow these steps (https://stackoverflow.com/a/6859020/28557) to add your jars to buildpath.
I tried to use Android-PullToRefresh in my project.
I am used to importing library by "File -> New -> Other... -> Android -> Android Project from Existing Code" in Eclipse, but this time, it said that "Select at least one project" when I choose the "library" folder in that project.
What is the correct way to import this library? Please help. Thanks!
If your workspace having the project with the same activity name as the activity in your library, this time also it will show select atleast one project. check if you work space contains any
If you are trying to import a library into Eclipse, then you may refer to this post Adding a library/JAR to an Eclipse Android project
If you are trying to import the project, then you select the entire project folder.
My android application, built inside Eclipse, suddenly fails to build with dozens of errors. The most obvious are errors indicating that all the android imports cannot be resolved.
import android.os.Bundle;
import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.media.AudioManager;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
All of these are flagged as unresolvable. I've tried removing and re-adding the JRE System Library. I've tried cleaning and rebuilding. I've tried the "Quick fix" option to "Fix Project Setup..." but that simply responds with a dialog box that say...
"No proposals have been found to fix the unresolvable reference to 'android.app.Bundle'. Click here to manually configure the build path of project 'Silent Mode Toggle."
I'm new to Android development and this one has me completely stumped.
Thanks in advance for any help you can provide.

It seems that your eclipse-workspace (or at least your Project) is broken somehow.
Have you moved your android-sdk/Project recently? If it's not an Android Project anymore, try to look at Preferences->Android for a valid android sdk-location.
If this is correct, try to open a complete new Workspace, and import your sources with File->import->Android Project from existing Source.
If this still doesn't help, make a new android Project and copy the sources manually inside your Project from outside Eclipse. Re-open Eclipse after that, and make a Project->clean
What all the others said.
Specifically, I recommend you go to Project > Properties > Java Build Path > Libraries and make sure you have exactly one copy of android.jar referenced. (Sometimes you can get two if you're importing a project.) And that its path is correct.
Sometimes you can get the system to resolve this for you by clicking a different target SDK in Project > Properties > Android, then restoring your original selection.
right click on project->properties->android->select target name as "Android 4.4.2" --click ok
since DocumentsContract is added in API level 19
I just had the same problem after accepting a Java update--scores of build errors and android import not recognized. On checking the build path in Project=>Properties, I found that the check box for Android 4.3 had somehow gotten cleared. Checking it resolved all the import errors without my even having to restart the IDE or run a project clean.
try this in eclipse: Window - Preferences - Android - SDK Location and setup SDK path
This import android packages cannot be resolved is also occurs when your using some library and that library is not in the same path where your application is there, or if you are importing the library and not coping library to the workspace
May be you are using this checking :
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
}
To resolve this you need to import android.provider.DocumentsContract class.
To resolve this issue you'll need to set the build SDK version to 19 (4.4) or higher to have API level 19 symbols available while compiling.
First, use the SDK Manager to download API 19 if you don't have it yet.
Then, configure your project to use API 19:
In Android Studio: File -> Project Structure -> General Settings -> Project SDK.
In Eclipse ADT: Project Properties -> Android -> Project Build Target
I found this answer from here
Thanks .
RightClick on the Project > Properties > Android > Fix project properties
This solved it for me. easy.
To import android packages, ADT plugin of eclipse is required, only after this you
can add it in the java build path.
Go to your eclipse market and download the Android AD extension.
