签名的 apk 不适用于低于 7.1.* 的设备

Question

I added a described question sometime ago, Signed APK, “App not installed” in some devices, and in some devices same apk is working fine The issue is stil unsolved

But just now I noticed that it is working fine on android devices on version 7.1.* and above, but below that it isn' working. Even it isn't working on emulator with MarshMallow. But I have set the minimum sdk on 18, so it should work fine. You can the Manifest, Gradle(app and project level) files on the questioon I provided link to.

Answer 1

For layout failures, you need to read the cause of the cause of the cause (etc) in your stack trace until you find the original error.

According to the stack trace, the issue is with your resource drawable/car_background .

Caused by: android.content.res.Resources$NotFoundException: Resource "com.diginfoexpert.MBAutodeals:drawable/car_background" (7f070069) is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f070069 a=-1 r=0x7f070069}

I'm not really sure why the issue would present on 7.1 devices. The only hint that may or may not be relevant according to 7.1 release notes is added support for circular launcher icons . I don't really see anything in 7.0 either.

Couple other off hand possibilities:

• Maybe you are using a vector asset and it is malformed.
• Maybe you are using a vector asset and not using app:srcCompat .
• Maybe you have an invalid file of name car_background in an API specific resource bucket.

Hopefully, this will get you on the right track.
