Android Lint erroneously thinks min SDK version is 1

Question

Eclipse refuses to build my Android project. In the package explorer, the project root node has the little red error symbol, but nothing else inside of it has this symbol. The Problems tab shows errors detected by Lint:

Call requires API level 3 (current min is 1): android.os.AsyncTask#<init>    Call requires API level 3 (current min is 1): android.view.GestureDetector#<init>    Call requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager#hideSoftInputFromWindow    Call requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager#hideSoftInputFromWindow    Call requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager#showSoftInput Call requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager#showSoftInput Call requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager#showSoftInput Call requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager#toggleSoftInput Call requires API level 3 (current min is 1): android.view.Menu#getItem  Call requires API level 3 (current min is 1): android.view.Menu#getItem  Call requires API level 3 (current min is 1): android.widget.HorizontalScrollView#getId  Call requires API level 5 (current min is 1): android.app.Activity#onBackPressed     Call requires API level 5 (current min is 1): android.app.Activity#onBackPressed     Call requires API level 5 (current min is 1): android.app.Activity#onBackPressed     Class requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager   Class requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager   Class requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager Class requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager   Class requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager   Class requires API level 3 (current min is 1): android.view.inputmethod.InputMethodManager Class requires API level 3 (current min is 1): android.widget.HorizontalScrollView Class requires API level 3 (current min is 1): android.widget.HorizontalScrollView Field requires API level 3 (current min is 1): android.os.Build#DISPLAY Field requires API level 4 (current min is 1): android.content.res.Configuration#screenLayout    Field requires API level 4 (current min is 1): android.os.Build#CPU_ABI  Field requires API level 4 (current min is 1): android.os.Build#MANUFACTURER Field requires API level 4 (current min is 1): android.os.Build$VERSION#SDK_INT 

My best guess is that Lint thinks my minSdkVersion is 1, which it isn't; my manifest declares minSdkVersion="8". I've tried the following in an effort to fix this:

• Restarting Eclipse
• Restarting my computer
• Project > Clean
• Manually deleting /bin and /gen to force hem to be generated again

At this point I'm out of ideas. Anybody have suggestions?

Answer 1

I have the same problem, and my solution is:

Right click on the project folder > Android tools > Clear Lint Markers

"Run Android Lint" makes some markers and the markers cause this error.

Answer 2

"Clear Lint Markers" in the Accepted Answer removed the error temporarily, but it kept coming back every time I saved a file in the affected project.

To make it stop reporting that error, I had to disable the lint check altogether:

Right click project -> Properties -> Android Lint Preferences  Search for "minSdk" in the search box  Click on "UsesMinSdkAttributes"  Click the "Ignore All" button at the bottom. 

Clean and rebuild the project, and Eclipse/ADT will no longer run the lint check for minSdk on your project.
