Android problems when import library project using Eclipse
11,739
Replace one of the specified android-support-v4.jar with the other, so that you have the same one in both places. That will resolve your issue.

So, I tried to add
v7 appcompat
support library with resource toMyFirstApp
project, by following the tutorial @http://developer.android.com/tools/support-library/setup.html
Both
android-support-v4.jar
andandroid-support-v7-appcompat.jar
files were exported. Eclipse includes theandroid-support-v4.jar
by default and when I tried the code:// MainActivity.java import android.support.v7.app.ActionBarActivity;// error public class MainActivity extends ActionBarActivity {...} // error // DisplayMessageActivity.java import android.support.v4.app.NavUtils; // error on this line public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.display_message, menu);// error at R return true; } public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: // This ID represents the Home or Up button. In the case of this // activity, the Up button is shown. Use NavUtils to allow users // to navigate up one level in the application structure. For // more details, see the Navigation pattern on Android Design: // // http://developer.android.com/design/patterns/navigation.html#up-vs-back // NavUtils.navigateUpFromSameTask(this);// error at NavUtils return true; } return super.onOptionsItemSelected(item); }
I got a number of errors:
