How to solve this error? gradlew clean not helps. Build folders deletion also not working. Android studio shows no errors while compiling.
I had this problem and just found the solution - answer is RTFM! Here are the instructions: https://developer.android.com/tools/building/multidex.html
Multidexing is a new feature and so requires a support library to be compatible with pre-lollipop devices. You need to add the following to your gradle file dependencies:
compile 'com.android.support:multidex:1.0.0'
Also enable multidex output in your gradle file:
android {
compileSdkVersion 21
buildToolsVersion "21.1.0"
defaultConfig {
...
minSdkVersion 14
targetSdkVersion 21
...
// Enabling multidex support.
multiDexEnabled true
}
}
And then add the multidex support application to your manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.multidex.myapplication">
<application
...
android:name="android.support.multidex.MultiDexApplication">
...
</application>
</manifest>
Note: If your app already extends the Application class, you can override the attachBaseContext() method and call MultiDex.install(this) to enable multidex. For more information, see the MultiDexApplication
reference documentation.
@Override
protected void attachBaseContext(Context context) {
super.attachBaseContext(context);
MultiDex.install(this);
}
Again, see the instruction above for more information...
Hope this helps
Was stuck for hours due to this issue but finally got the solution.
Step#1:
dependencies {
compile 'com.android.support:multidex:1.0.0'
}
Step#2:
defaultConfig {
multiDexEnabled true
}
Step#3:
public class AppController extends Application {
@Override
public void onCreate() {
super.onCreate();
MultiDex.install(this);
}
}
Happy coding!
Following solution worked for me:
Add
multiDexEnabled = true
in yourdefault Config
Add compile
com.android.support:multidex:1.0.0
in your dependenciesApplication class extend MultiDexApplication
instead of justApplication
In our case we got this error when we updated "support-v4" lib from 19 to 24 version.
Version 19 contains NavUtilsJB class:
But version 24 does not contain NavUtilsJB class:
Solution for this issue was just to create NavUtilsJB class inside our project:
package android.support.v4.app;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
class NavUtilsJB {
public static Intent getParentActivityIntent(Activity activity) {
return activity.getParentActivityIntent();
}
public static boolean shouldUpRecreateTask(Activity activity, Intent targetIntent) {
return activity.shouldUpRecreateTask(targetIntent);
}
public static void navigateUpTo(Activity activity, Intent upIntent) {
activity.navigateUpTo(upIntent);
}
public static String getParentActivityName(ActivityInfo info) {
return info.parentActivityName;
}
}
