android studio gradle中的渲染错误相关

Question

I'm trying to use this lib (tokenautocomplete) from splitwise.

I inserted it on my build.gradle and it synced normally.

But, when I try to use some dependency from this lib, like this for example:

    <com.tokenautocomplete.TokenCompleteTextView
        android:id="@+id/searchView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

I get the following rendering problem:

Rendering Problems The following classes could not be instantiated: - com.tokenautocomplete.TokenCompleteTextView (Open Class, Show Exception, Clear Cache) Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE Exception Details java.lang.InstantiationException at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at android.view.LayoutInflater.rInflate_Original(LayoutInflater.java:806) at android.view.LayoutInflater_Delegate.rInflate(LayoutInflater_Delegate.java:64) at android.view.LayoutInflater.rInflate(LayoutInflater.java:782) at android.view.LayoutInflater.rInflate_Original(LayoutInflater.java:809) at android.view.LayoutInflater_Delegate.rInflate(LayoutInflater_Delegate.java:64) at android.view.LayoutInflater.rInflate(LayoutInflater.java:782) at android.view.LayoutInflater.inflate(LayoutInflater.java:504) at android.view.LayoutInflater.inflate(LayoutInflater.java:385)

I'm with this problem for a few hours, did my google searches and found nothing.

I would like some help.

By the way, my dependencies in my build.gradle look like this:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile "com.android.support:support-v4:23.1.0"
compile "com.android.support:appcompat-v7:23.1.0"
compile "com.android.support:support-v13:23.0.+"
compile "com.beardedhen:androidbootstrap:2.0.0"
compile "com.splitwise:tokenautocomplete:2.0.2@aar"
compile "com.google.android.gms:play-services-location:7.5.0"
compile "com.android.support:design:23.0.1"
}

Answer 1

This is because the TokenCompleteTextView in the library you are using is not properly configured to support Android Studio's preview.

The view will (presumably) still work fine if you run your app on a device or the emulator.

If you want support for Android Studio's preview pane, you should file a bug with the library's author.
