Error : java.lang.NoClassDefFoundError Android

问题:

I am following this tutorial to create swipe tabs. But I get the above error.

My gradle dependencies sturucture

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:22.2.0'
}

Here are my files. MainActivity.java

import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);


    TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
    tabLayout.addTab(tabLayout.newTab().setText("Tab 1")); //this line gives error
    tabLayout.addTab(tabLayout.newTab().setText("Tab 2")); //this line gives error
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

    final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
    PageAdapter pageAdapter = new PageAdapter(getSupportFragmentManager());
    viewPager.setAdapter(pageAdapter);
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
    tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });
 }

}

And my PageAdapter.java file is

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;

public class PageAdapter extends FragmentStatePagerAdapter {

  public PageAdapter(FragmentManager fm) {
    super(fm);
  }

  @Override
  public Fragment getItem(int position) {

    switch (position) {
        case 0:
            return new InstaPicSwipeTab();
        case 1:
            return new SongsDownloadSwipeTab();
    }
    return null;
 }

 @Override
 public int getCount() {
    return 2;
 }
}

And this is what LogCat is giving me

How to solve this error?

回答1:

The version of support library and design library should be the same.

I changed my

compile 'com.android.support:appcompat-v7:23.1.1'

to

compile 'com.android.support:appcompat-v7:23.0.1'

and issue fixed for me.

Note: my compileSdkVersion and buildToolVersion is below compileSdkVersion 23 buildToolsVersion "23.0.1"

回答2:

this comes up when a class exists at compile time but not at runtime, right click on the app go to open module settings select dependencies click on the + and select 'library dependency' select design and click ok, wait for gradle to run, re-run your app, am sure that will fix it.

your top level gradle will need to look like this

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion '23.0.2'

defaultConfig {
    applicationId "aubry.chromio.com.dressup"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"

}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile fileTree(dir: 'libs', include: ['*.java'])
    compile fileTree(dir: 'libs', include: ['*.so'])


    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:design:23.1.0'

}

回答3:

You must have to import same appcompat and design libraries and also 12.2.0 version.

I fix it by importing these libraries.

compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:recyclerview-v7:25.2.0'
compile 'com.android.support:support-v4:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'

回答4:

You just add this: compile 'com.android.support:design:22.2.0' or high version : compile 'com.android.support:design:25.0.0' is nice.

support:design has contained support:appcompat.
