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>

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.

Answer 3

Make sure you have android: namespace identifier together with minSdkVersion attribute. Like this:

android:minSdkVersion="8".

When creating a project based on some Android sample projects (like BluetoothChat) the namespace gets omitted and confuses Lint. Then even clearing Lint Markers doesn't truly cure the issue as they reappear after running Lint again, which happens automatically pretty often.

Note: this was verified with samples revision 1 for API16

Answer 4

Try right clicking on the project folder > Android tools > fix properties

You should also check in the build properties that all your android libraries and things are checked and loading in the correct order. Right click on the project > Properties > Build

Answer 5

A simple Project -> Clean also fixed the issue for me.
