There is no compiler error. I am getting this error in runtime.

By using android new Android App Bundle i have found Resource Not Found Crashes in 2 of my google play store apps :-

Here is the stacktrace from fabric for one of the app:-

The activities working fine even the newly create fragments work, but if i go to the old fragment classes the app stops working and i can see the error in console :

I need downgrade my minsdk for keep compatibility with some devices, so I need downgrade my version from minsdk16 -> 15. But im having this error:

Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.github.flipagram:android-assetcopier:0.1.1] C:\Users\beto_.gradle\caches\transforms-1\files-1.1\android-assetcopier-0.1.1.aar\7ee049aa00fd85016b1a1ae60ce050df\AndroidManifest.xml as the library might be using APIs not available in 15 Suggestion: use a compatible library with a minSdk of at most 15, or increase this project's minSdk version to at least 16, or use tools:overrideLibrary="flipagram.assetcopylib" to force usage (may lead to runtime failures)

This is my current build.grandle, but when i change the minsdk to 16, get the error showed before.

Exactly as the title suggests when I have a floating action button anywhere in my layout in any xml file the preview stops working, I can literally comment it out and it will instantly redraw perfectly. any ideas?

I have tried resetting multiple times syncing, invalidating caches etc. When i reset the view is rendered fine but only for pages open any i open after will not render and navigating back to the previously rendered layout breaks it

The only thing I can think of is I use clans floating action button in my project, but it's the Google one that breaks my preview.

EDIT I've removed clans cleaned project invalidated caches restarted and still the issue persists

also if i change FloatingActionButton to ExtendedFloatingActionButton the preview draws fine, looking into those two it seems they extend completely different classes

Also using AndroidX

here is an example of an xml that will not render

I want to make the AlertDialog box for my app look like the ones on Android > 6.0.0 ( as depicted in the following screenshots) for all lower android version till 4.4.4. I have applied a custom style for the dialog box.

Following is the style in styles.xml for AlertDialog:

The issue is very simple to explain, I'm getting error

Exception while processing task java.io.IOException: java.lang.ArrayIndexOutOfBoundsException: 4

while building APK. At first, I didn't enable minify and it worked (but produced NoClassFoundError). That's why I enabled the minify in the build.gradle file. Initially, I got a lot of warnings from pro guard, So I ignored all of them using -dontwarn. After ignoring all warnings I got the above-mentioned exception. I don't know what went wrong. Here I've attached both gradle file and pro guard content.

build.gradle

For the first time I'm trying to use Android Studio (3). Probably I'm asking a silly question, but I didn't find any exact answer for my level of knowledge in internet.

I'm trying to modify an android project, and it's more than one hour Android Studio is just updating and syncing gradle. After all these, it shows such a warning:

I have been developing apps using firebase for over an year now. Today when I open Android Studio suddenly all my projects built on Firebase are throwing the following error:
