Trying to call the interface method 'void android.support.v7.widget.DecorContentParent.setWindowCallback (android.view.Window $ Callback)'

here is my project:

project

animated_path.xml:

<?xml version="1.0" encoding="utf-8"?> <animated-vector xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:drawable="@drawable/triangle" tools:targetApi="21"> <target android:name="t" android:animation="@animator/path"/> </animated-vector>

path.xml:

 <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <objectAnimator android:duration="3000" android:propertyName="pathData" android:repeatCount="infinite" android:repeatMode="reverse" android:valueFrom="M 100 100 L 300 100 L 300 300 L 100 300z" android:valueTo="M 100 100 L 300 100 L 200 300 L 200 300z" android:valueType="pathType"/> </set>

AndroidManifest.xml:

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.kycq.reader"> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".LoadingActivity" android:theme="@style/ActivityTheme"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> <activity android:name=".MainActivity" android:theme="@style/ActivityTheme"> </activity> </application> </manifest>

LoadingActivity.java:

 public class LoadingActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_loading); } }

activity_loading.xml:

 <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.kycq.reader.LoadingActivity"> </RelativeLayout>

styles.xml:

 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item> </style>

build.gradle:

 apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "23.0.2" defaultConfig { applicationId "com.kycq.reader" minSdkVersion 14 targetSdkVersion 23 versionCode 1 versionName "1.0" // enable vectorDrawable vectorDrawables.setUseSupportLibrary(true) } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' // use 23.2.0 compile 'com.android.support:appcompat-v7:23.2.0' }

why am I getting an error when using the "animated vector" in the beta version of Android Studio 2.0?

error

Incredibly, when I delete "res / animator" and "animated_path.xml" and then rebuilds the project, it works.

it makes me go crazy, I don’t know why, and how to solve the problem, can anyone help me?

Scary, it once throws an error:

  java.lang.RuntimeException: Unable to start activity ComponentInfo{com.kycq.reader/com.kycq.reader.LoadingActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

but I set the ActivityTheme style to LoadActivity.

Now I publish the project on the Internet: https://drive.google.com/open?id=0B7cSTEJuaMZBLW9VYWM5X0szVlk

We had a similar question this morning. How do I fix it:

  • Remove the application level attribute from the android:theme="@style/AppTheme" manifest file android:theme="@style/AppTheme" .

  • Add an activity level attribute like this:

     [Activity(MainLauncher = true, Theme = "@style/AppTheme")]

This problem occurs when your buildToolsVersion not updated according to the version of playservices and other dependencies
