When I first started learning Android, I had this problem, and every time I opened and ran Android project, I would jump out of this tip:
Ignoring it the program can run but always feel a little uncomfortable
There are a number of solutions available online:
1. Open the project's Androidmanifest.xml file, android:targetsdkversion="21" to "20" or the following value. Because Android L is a preview version, this issue is caused by the version number or the use of "20". Once you have modified it, you can do this once with the Fix project properties, Project--Context Menu, Android Tools, and solve the problem.
2. Window--->preferences----->android--------> LInt Error Checking----->when saving files, check for errors
3, remember where to see, say what is 32-bit eclipse and 64-bit Java or Android mismatch problem
Tried method One, it didn't work for me ⊙▂⊙
Look at method two, but do not pop the window hint, but this is not afraid of trouble ignore mistakes, not called to solve the problem
Method Three, see all the tools are 64-bit
Finally, it might be inspired by method three, and found that my eclipse was followed by an indigo, 100 degrees is the version number, which has not been updated for a long time. Re-download the Luna version, then open, run project does not pop windows, right-project-android tools-run Lint:check for common errors:
The reason for this obsession with Android Lint is that Android lint is a static Code analyzer specific to Android, and "in fact, it's a special program for code error checking without the need for code to run." Based on the knowledge of the Android framework, Android lint in-depth check the code to find out what the compiler could not find. "In addition, Android Lint is able to check the object type defined in the XML file." "How can a tool like this bunker keep it in place ...
(The results found many errors or do not know how to come, had to delete the error after the run haha ha!) But for me, the Android lint window problem is finally solved.
