2. Solutions

1. Try build – & gt; clean project recompilation or invalid
2. Try to restart Android studio is invalid

Then I went to the build/outputs/APK directory and found that the APK file was compiled, but the file name was:
oyp_ 2.3.4_ I2Base_ 6478_ official_ debug.apk
as shown in the figure below:

So the reason is that the compiled APK file of Android studio is

OYP_ 2.3.4_ I2Base_ 6478_ official_ debug.apk

And it’s going to install the APK file name

OYP_ 2.3.4_ I2Base_ 6476_ official_ debug.apk
as a result, an error will be reported. Google looked up the error and found it in http://stackoverflow.com There is a solution to this error on the website, and the link is as follows:
