Android APK cannot be installed and the solution to the flash back problem

Android APK cannot be installed and flashback

The app can't be opened on some mobile phones (lower versions) or flash back when it is opened

Before the project integration is the SDK of the letter, the SDK of the letter is really good, customer service is also very awesome. However, in the process of integration, it is found that APK cannot be released on the mobile phone, or it cannot be opened after installation, and it will flash back after opening: the problem has two aspects

1. I used to do instant messaging for Huanxin. After integrating the SDK of Huanxin, I can open and flash back on the 4. X mobile phone. I can only open the app on the 5. X and 6. X mobile phones

2. I have encountered the same problem recently, but this time it is different from the last time. This time it is because my as has been upgraded to 2.3.. so I have encountered this problem twice and decided to record it today

The treatment method of this problem is divided into three parts:

1. Turn off the instant run of Android studio, setting ----- search for instant run, as shown in the figure:

2. Then clear out all caches of as. Method: delete the build files

3. Clear project clean up the project

Then rerun the project
