Layout null pointer error

[imperialstormtrooper]

I have hooked up the code as described in the ReadMe and am getting the following error when my Activity is rendering:

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.graphics.drawable.Drawable.isProjected()' on a null object reference at android.graphics.drawable.LayerDrawable.isProjected(LayerDrawable.java:422) at android.view.View.invalidateInternal(View.java:16653) at android.view.View.invalidate(View.java:16613) at android.view.View.setFrame(View.java:20958) at android.view.View.layout(View.java:20851) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.RelativeLayout.onLayout(RelativeLayout.java:1080) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.RelativeLayout.onLayout(RelativeLayout.java:1080) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1791) at android.widget.LinearLayout.layoutHorizontal(LinearLayout.java:1780) at android.widget.LinearLayout.onLayout(LinearLayout.java:1546) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1791) at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1635) at android.widget.LinearLayout.onLayout(LinearLayout.java:1544) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1791) at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1635) at android.widget.LinearLayout.onLayout(LinearLayout.java:1544) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1791) at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1635) at android.widget.LinearLayout.onLayout(LinearLayout.java:1544) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.FrameLayout.layoutChildren(FrameLayout.java:323) at android.widget.FrameLayout.onLayout(FrameLayout.java:261) at android.widget.ScrollView.onLayout(ScrollView.java:2492) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.FrameLayout.layoutChildren(FrameLayout.java:323) at android.widget.FrameLayout.onLayout(FrameLayout.java:261) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.FrameLayout.layoutChildren(FrameLayout.java:323) at android.widget.FrameLayout.onLayout(FrameLayout.java:261) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1791) at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1635) at android.widget.LinearLayout.onLayout(LinearLayout.java:1544) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.widget.FrameLayout.layoutChildren(FrameLayout.java:323) at android.widget.FrameLayout.onLayout(FrameLayout.java:261) at com.android.internal.policy.DecorView.onLayout(DecorView.java:945) at android.view.View.layout(View.java:20854) at android.view.ViewGroup.layout(ViewGroup.java:6401) at android.view.ViewRootImpl.performLayout(ViewRootImpl.java:2912) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:2599) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1743) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:7773) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:911) at android.view.Choreographer.doCallbacks(Choreographer.java:723) at android.view.Choreographer.doFrame(Choreographer.java:658) E/AndroidRuntime: at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:897) at android.os.Handler.handleCallback(Handler.java:789) at android.os.Handler.dispatchMessage(Handler.java:98) at android.os.Looper.loop(Looper.java:164) at android.app.ActivityThread.main(ActivityThread.java:6949) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.Zygote$MethodAndArgsCaller.run(Zygote.java:327) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1374)

I have verified it is the inclusion of the country code that is causing the error (when I remove all references it works). I am using the control in a DialogFragment, the xml:

<com.hbb20.CountryCodePicker android:id="@+id/sms_text_ccp" android:layout_width="wrap_content" android:layout_height="wrap_content" />

The reference itself causes the error (even if I don't hook it up). If I do hook it in it looks like:

CountryCodePicker mCountryCodePicker = dialog.findViewById(R.id.sms_text_ccp);

Here is the inclusion in my gradle:

dependencies { implementation project(':androidpdfview100') implementation 'com.android.support:support-v13:27.1.1' implementation 'com.google.code.gson:gson:2.8.0' implementation 'joda-time:joda-time:2.5' implementation 'com.google.android.gms:play-services-maps:11.6.2' implementation 'com.hbb20:ccp:2.2.2' implementation('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') { transitive = true; } implementation 'com.urbanairship.android:urbanairship-sdk:8.6.+' implementation 'com.google.android.gms:play-services-gcm:11.6.2' // Recommended for in-app messaging implementation 'com.android.support:cardview-v7:27.1.1' // Recommended for location services implementation 'com.google.android.gms:play-services-location:11.6.2' }

I have included all my dependencies in case there is some conflict. I did notice that including the co,.hbbb20.2.2.2 also forced me to upgrade to 27 sdk and the supporting libraries.

Thanks

Hey, here is one of the same issues people faced in the past.

I would like to copy the same answer here. If it works, please post back here so that we can close this issue

Most probably you are using parent="@android:style/Theme.Holo.Light.DarkActionBar" as your app theme's parent. Nowadays it is recommended to switch to parent theme parent="Theme.AppCompat.Light.DarkActionBar". This will let you use latest Android features in your app and also fixes this error.

If you do not want change your Theme parent, here is a workaround:

1. Download the zip file using this link => https://goo.gl/c6usWS
2. Extract the zip file you will get one, folder named "drawable-v21"
3. Copy this folder and paste it into your project's res/ folder. (/app/src/main/res/drawable-v21) If you already have this folder, simply merge this new folder with your existing one.
4. Rebuild the project
5. Run the app

If you don't want to change the the support library versions you can exclude them while fetching CCP artifact. Simply add exclude instructions in gradle file. For example,

implementation('com.hbb20:ccp:2.2.2', {
        exclude group: 'com.android.support'
    })

I hope this will be helpful.

Harsh, Thanks for the quick reply. Sorry I missed the previous error report - the title threw me off. That was the problem, and your zip file suggestion fixed the issue ( tried the theme change but it ended up blowing up on action bar creation - this app is really old, I will try theme changes later when I am not under a deadline). I am not too worried about moving to 27, having recently moved to 26 and fixed the related issues it brought. Thanks again for the help and the very cool country code picker Stephen
