andriud studio 用 gradle 加入第三方 library 后编译没问题，在机器上测试报 java.lang.NoClassDefFoundError

[fenjuly]

我看到遇到相同问题的解决办法是在项目根目录运行./gradlew clean 我尝试了但是错误依然在

希望各位能帮忙看一下，非常感谢！

dependencies {
compile "com.daimajia.swipelayout:library:1.0.9@aar"
}

我的代码：MainActivity.java

public class MyActivity extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
SwipeLayout swipeLayout = (SwipeLayout) findViewById(R.id.sample1);

//set show mode.
swipeLayout.setShowMode(SwipeLayout.ShowMode.LayDown);

//set drag edge.
swipeLayout.setDragEdge(SwipeLayout.DragEdge.Left);

swipeLayout.addSwipeListener(new SwipeLayout.SwipeListener() {
@Override
public void onClose(SwipeLayout layout) {
//when the SurfaceView totally cover the BottomView.
}

@Override
public void onUpdate(SwipeLayout layout, int leftOffset, int topOffset) {
//you are swiping.
}

@Override
public void onOpen(SwipeLayout layout) {
//when the BottomView totally show.
}

@Override
public void onHandRelease(SwipeLayout layout, float xvel, float yvel) {
//when user's hand released.
}
});
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

确定组件下载下来了？repositories写好了？

[fenjuly]

@dupengtao 嗯，编译都通过了

[inferjay]

是否开启了混淆？如果开启了混淆，需要在proguard-android.txt中配置混淆规则，忽略第三方libray的规则：
-dontwarn com.daimajia.swipe.**
-keep class com.daimajia.swipe.**{*;}
有木有更详细的错误日志？

[fenjuly]

@inferjay 你好，谢谢你的回答，不过我关闭了混淆的runProguard false。 下面是我的详细错误日志

@inferjay 我已经找到问题了The problem is class not found, the missing class is in android support library. Just add the support library then solved. Clear?

还是感谢你
