Error: Program type already present: com.getcapacitor.AndroidProtocolHandler

I want to generate APK of the ionic app but I am getting
Program type already present: com.getcapacitor.AndroidProtocolHandler
error while building the ionic 4 app with angular. I have searched this on the internet and find one solution which says change
implementation 'ionic-team:capacitor-android:1+'
to
implementation project(':capacitor-android')"
in dependencies in build.gradle file but I already have implementation project(':capacitor-android')" in my dependency and I'm still getting the error.
This is link to the solution I have tried: https://github.com/oxylian/capacitor-facebook-login/issues/3
This is my build.gradle file

The problem is the date picker plugin, it has that line that you have mentioned
https://github.com/triniwiz/capacitor-datepicker/blob/master/src/android/capacitor-datepicker/build.gradle#L45
There is a pull request fixing it, but hasn’t been merged

app:transformClassesWithDexForDebug exception and java.util.concurrent.ExecutionException

I am getting below Error while running my Application.
Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

I think the issue is with my .gradle file. Maybe some duplication for dependency in my .gradle file. I have removed one but, still getting the error.

Try adding multiDexEnabled true in defaultConfig.
Moreover, its not recommended to use com.google.android.gms:play-services:11.0.2 directly rather include the dependencies you want to work with separately. Like if you want to work with Google Maps, then add only com.google.android.gms:play-services-maps:11.1.0 and so on.

com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536
You've hit the dex limit for the number of methods that can be used in which affects all device lower than Android 5.0(21).
To fix this you need to enable multi-dex in your gradle and have your application extends MultiDexApplication to work around with the max Dex limit.
android {
defaultConfig {
...
minSdkVersion 21
targetSdkVersion 26
multiDexEnabled true
}
...

ClassDefNoFound on API 22 x_86 level API

I am facing a strange problem in API level 22 (lollipop) mobiles.
Mobiles using these API levels are working fine
API 24
API 23
But when i run my app on API level 22 mobile, it gives me following error message.
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.squareup.picasso.Picasso"
on path: DexPathList[[zip file

at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56)
However this is not Picasso related problem, if i remove Picasso library it starts giving me error messages on other classes.

Did you manually re-sync gradle after your changes? Did you also change build-tools version in your build.gradle to match API 22 as well? The errors you're showing I've only seen when gradle hasn't rebuilt or resynced properly. I would also try to manually do it from the command line... (in OS X), ./gradlew clean, ./gradlew assemble

This is the error that i got after try the resolve

I highly suggest not to compile compile 'com.google.android.gms:play-services:8.4.0'
as it is,
Which is one of the main cause of 64K method dex limit.
The separate compilations beyond play-services itself is listed Here, Use the one you really need rather than compiling the whole play-services.

Is your project a very large one? I'm suspecting that it may be going over the method limit of 64k. Have a look at this documentation. It may help.
