error scenario
, directly create a new android project, all default configuration, after running error, but the error will not affect the use, will not cause flash back, so the error level is not very high, even can not deal with, but a little obsessive I still decided to solve it
error analysis
Rejecting re-init on previously-failed class java.lang.Class<android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;
prompt class find error: Java. Lang. NoClassDefFoundError , and indicates the class
android/view/view $OnUnhandledKeyEventListener , so we found this interface according to the directory:
android View class. PNG
figure top left see a row of prompts, prompt no API 28 resources! I see, I did not install the android SDK, 28 API, but I compiled version is api28 , although this is not the root cause of the problem (even if you have installed the android 9.0 is api28 SDK is also an error), but it reminds me that may be the reason for the runtime platform, and my mobile phone system debug is 27 API, compiled versions than low!!!!! :
app build.gradle file. PNG
so far, we know the solution to the problem
solution
My mobile phone is api27. Note that dependency also needs to be changed to
after modification. PNG
debug again, the console did not report an error again! In the spirit of verification, I searched the interface I just failed to find, and found that
was really not found in api27 platform
cannot search the class. PNG
looks like the interface is indeed the beginning of API 28.
summary
The
compiled version should not be misused, need to be careful. Not a big deal, just give your ocD friend a solution to the problem.
