For an app targeting Android SDK Version 31(Android 12 OS) or above we need to set the android:exported="true" for any of our app's own activity and any 3rd party library's activity in our app's manifest, where ever the <intent-filter... is added.
We faced this issue for auth0 Android SDK.

Manifest Errors after upgrading Gradle

I have recently decided to upgrade my Android project to gradle 4.4 (because jack was way too slow), but I now have another issue.
Please, do NOT reply with "android.enableAapt2=false" as this is not a solution, it basically just ignores all these errors.
50% of my AndroidManifest.xml reports errors. (you can see the contents below)

Why my app is not compatible with my own phone in google play

I know this questions has been asked a lot but I really don't get any answer
My app is not compatible with any phone:

Don't use this code in manifest.. if you are using android studio
just check in your app.gridle file min and target SDK api no

Error:The value of attribute "android:name" associated with an element type "null" must not contain the '<' character

I am a novice trying to figure out the error. But I have reached upon no solution even after trying it several times.
I am sharing the android-manifest.xml file code. More details are after this code.

So, what I am trying to do here is to integrate a chat feature in a small time-stopper app that I just created for the learning purpose and I am integrating it also for the learning purpose.
When I build gradle,Result shows Error:The value of attribute "android:name" associated with an element type "null" must not contain the '<' character.
and
Error:Cannot read packageName from C:\Users\APnaturals\AndroidStudioProjects\TimeStopper\app\src\main\AndroidManifest.xml
When I replace APP_PKG_NAME with the one mentioned in here
manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.home.timestopper"
Gradle Build fails again without giving any cause.

<category android:name="<APP_PKG_NAME>" />
Looks like you forgot to configure your package name in this element.

Simply remove the APP_PKG_NAME from metadata and put your package name or ID, as in androidmanifest.xml not allow <>.

Apk only supported by 1 device

I have a problem with an application that I try to publish on the platform the Play Store. When I uploaded the .apk file I have seen that it is only compatible with 1 device. I have reviewed the file AndroidManifest.xml and I have not found anything that restricts the use in other device. The application takes the same permissions as any other similar application that I have published, and this other is compatible with more than 8000 devices. The only thing that is different is that in this new app I've added the service GCM with their required permissions, and the bitcoinj-0.12.3 library. What is the reason for which is not compatible with more devices? These are all the permissions that I have declared in the file AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.my.app" >
<uses-permission android:name="android.permission.CAMERA" />

This a scrrenshot of analisis from Google Play:
EDIT: I have read the post Android app is supported by 0 devices, but I haven't managed to fix anything
EDIT 2: Posted the complete AndroidManifest.xml file.

you can prevent the problem by doing this in your build.gradle
compile 'com.google:bitcoinj:0.11.3#jar'
// the above #jar is important
// context: https://stackoverflow.com/questions/22730620/bad-apk-when- using-bitcoinj-from-maven-central
