I'm trying to preview my MainActivity XML file and I'm getting this error:
java.lang.ClassNotFoundException: android.support.v4.widget.DrawerLayoutImpl
My Main Fragment and Navigation Drawer Fragment are working just fine.
Searched all over these forums and tried a bunch of things to no avail. I know it must be an issue with the library and my gradle build but I'm not sure what I'm doing wrong:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion '21.0.0'
defaultConfig {
applicationId "com.example.example"
minSdkVersion 17
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:support-v4:21.0.0'
compile 'com.parse.bolts:bolts-android:1.1.2'
compile 'com.android.support:support-v13:21.0.0'
compile fileTree(dir: 'libs', include: 'Parse-*.jar')
compile project(':facebook')
}
v4 was added automatically by android studio since I was using a navigation drawer. v13 I included myself (by going to project structure-->dependencies and adding it there) thinking it would help. I copied both .jar files to my libs folder thinking that would help as well. Cleaned project/synced gradle did all of that, not sure what else to do.
Just in case, here is what Android Studio created for me for activity_main.xml
<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout

space available using match_parent in both dimensions. -->
<FrameLayout

<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.

android:layout_gravity="left" instead. -->
<!-- The drawer is given a fixed width in dp and extends the full height of
the container. -->
<fragment android:id="@+id/navigation_drawer"
android:layout_width="@dimen/navigation_drawer_width"
