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
Answer：
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.
Answer：
right click on project->properties->android->select target name as “Android 4.4.2” –click ok
since DocumentsContract is added in API level 19
Answer：
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.
Answer：
try this in eclipse: Window - Preferences - Android – SDK Location and setup SDK path
Answer：
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
Answer：
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
