Add this to dependencies: implementation ‘androidx.appcompat:appcompat:1.0.2’. Add this: import androidx.fragment.app.FragmentTransaction;. Switch your activity extends from Activity to AppCompatActivity. Change from getFragmentManager() to getSupportFragmentManager(). This will fix your issue.
Note that you can get around this 20dp peek feature by setting the clickable attribute to true on the FrameLayout within the DrawerLayout. android:clickable=”true” for instance : http://developer.android.com/training/implementing-navigation/nav-drawer.html <android.support.v4.widget.DrawerLayout xmlns:android=”http://schemas.android.com/apk/res/android” android:id=”@+id/drawer_layout” android:layout_width=”match_parent” android:layout_height=”match_parent”> <!– The main content view –> <FrameLayout android:id=”@+id/content_frame” android:layout_width=”match_parent” android:layout_height=”match_parent” android:clickable=”true” /> <!– The navigation drawer –> <ListView android:id=”@+id/left_drawer” android:layout_width=”240dp” android:layout_height=”match_parent” android:layout_gravity=”start” … Read more
From the quoted documentation: it is strongly recommended to use the Activity Result APIs introduced in AndroidX Activity 1.2.0-alpha02 and Fragment 1.3.0-alpha02. Neither of those are in your dependencies, at least the portion from your question. You have been manipulating appcompat, not activity or fragment. Add either or both of: implementation “androidx.activity:activity:1.2.0” implementation “androidx.fragment:fragment:1.3.0” (or … Read more
I experienced this exact same problem today, and was able to solve. Turns out the issue was a version mismatch between the expected version of androidx.lifecycle:lifecycle-viewmodel used by the module where the “failing” class is and a later version in some other dependent code. So in my case, my module was using version 2.1.0 of … Read more
After I upgraded my Android studio and gradle plugin, I ran into similar issue because of the below line. I was using this <import type=”java.lang.String” /> in my layout file. Removing this import solved the issue. Just as in managed code, java.lang.* is imported automatically.
I had the same issue. The cause of the issue for me was that my Worker class was a nested class. The moment I made it an independent class, it worked.
I caught this error when I tried to add Jetpack to my existing app. I followed Suraj’s answer, even used the newest Kotlin gradle plugin, and couldn’t exactly figure out what was wrong. I also followed the official setup guide and it didn’t work. Everything seemed okay, but nothing helped. Installing Android Studio 4.0 canary … Read more
You need to use com.google.android.material.appbar.AppBarLayout. Version 1.0.0 is already out So you can use implementation ‘androidx.appcompat:appcompat:1.0.0’ Add dependency implementation ‘com.google.android.material:material:1.0.0’ See Material Component integration for latest release version. And use <com.google.android.material.appbar.AppBarLayout android:layout_width=”match_parent” android:layout_height=”wrap_content”> </com.google.android.material.appbar.AppBarLayout> For other artifact and Class Mapping see the AndroidX migration Doc.
I think that’s because you’re missing one dependency: implementation “androidx.lifecycle:lifecycle-common-java8:$lifecycle_version” Get the latest version of lifecycle-common-java8 here See the documentation: If you use Java 8 Language, then observe events with DefaultLifecycleObserver. To include it you should add “androidx.lifecycle:lifecycle-common-java8:” to your build.gradle file.
Ofcourse, we have Progress Bars in Jetpack Compose: CircularProgressIndicator: Displays progress bar as Circle. It is indeterminate. Themed to Primary color set in styles. Another variant is determinate that takes progress in argument as Float (0.0f – 1.0f) Example: // Indeterminate CircularProgressIndicator() // Determinate CircularProgressIndicator(progress = 0.5f) LinearProgressIndicator: Displays progress bar as line. It is … Read more
