error description:

Error:Some file crunching failed, see logs for details

recently a lot of readers have asked me why I still get an error after I add it according to my method. So let me add a little bit here.

note ⚠ ️ : this is a question! So if you read the error log for Gradle, you can read the error log for Gradle.

click on the Gradle Console in the lower right corner. View gradle detail log:

problem 1:

images in resource files are not PNG files.

problem 2:

is not given. Figure 9 has margins.

Log Log 1:

AAPT: libpng error: Not a PNG file
Error: Some file crunching failed, see logs for details
:app:mergeDebugResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ‘:app:mergeDebugResources’.
> Error: Some file crunching failed, see logs for details

* Try:
Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output.

BUILD FAILED

reason 1 solution:

in the build.gradle file of project app, add:

in the android TAB

aaptOptions {
        cruncherEnabled = false
        useNewCruncher = false
}

reason 2 solution:

We looked at the log and found that there is no margin. What is margin?Let’s look at the following two pictures

Boundless space (with no black edges)

There are margins and there are black edges all around.

so how to set up?

Click on the white edge, the position of the click will be black, left and right or drag up and down to change the black edge, so as to set the size of the margin.

error reasons may not only have the above two kinds of log, if you encounter other reasons, welcome everyone harassment!!
