Mihir Srivastava :

I am using androidx to create a basic directory app. Using a FloatingActionButton to add entries. The App runs perfectly on an emulator but when ran on my mobile it shows an android.view.InflateException.

The Error - 

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.vestige.directory2, PID: 10648
    java.lang.RuntimeException: Unable to start activity ComponentInfo{com.vestige.directory2/com.vestige.directory2.Activities.MainActivity}: android.view.InflateException: Binary XML file line #26: Binary XML file line #26: Error inflating class com.google.android.material.floatingactionbutton.FloatingActionButton

FloatingActionButton XML (This code is from line 26 as in the error.)- 

 <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_plus_white" />

MainActivity Code - 

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = findViewById(R.id.fab);

        fab.setOnClickListener(v -> addInformation());

I have referred many solution and mostly all of them talk about changing android:backgroundTint to app:backgroundTint which as you can see I am not even using.

My build.gradle(Module: app) dependencies - 

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.android.material:material:1.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    // Room components
    implementation "androidx.room:room-runtime:$rootProject.roomVersion"
    annotationProcessor "androidx.room:room-compiler:$rootProject.roomVersion"
    androidTestImplementation "androidx.room:room-testing:$rootProject.roomVersion"

    // Lifecycle components
    implementation "androidx.lifecycle:lifecycle-extensions:$rootProject.archLifecycleVersion"
    annotationProcessor "androidx.lifecycle:lifecycle-compiler:$rootProject.archLifecycleVersion"

    //Gson
    implementation 'com.google.code.gson:gson:2.8.5'
}

My styles.xml - 

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.MaterialComponents.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>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.MaterialComponents.Dark.ActionBar" />

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.MaterialComponents.Light" />

</resources>

ic_plus_white.xml - 

<vector android:height="23dp"
    android:viewportHeight="512"
    android:viewportWidth="448"
    android:width="20dp"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <path

</vector>

SOLVED: Just had to move my drawable ic_plus_white.xml from drawable-v-24 folder to drawable folder. Solved the issue!

Deˣ :

Please make sure your app or the activity theme inherits one of the following themes:

  • Theme.MaterialComponents
  • Theme.MaterialComponents.NoActionBar
  • Theme.MaterialComponents.Light
  • Theme.MaterialComponents.Light.NoActionBar
  • Theme.MaterialComponents.Light.DarkActionBar
  • Theme.MaterialComponents.DayNight
  • Theme.MaterialComponents.DayNight.NoActionBar
  • Theme.MaterialComponents.DayNight.DarkActionBar

It seems your drawable/ic_plus_white is not a valid drawable. Please verify it's content too.
