先上图吧就两张静止图片吧：

接三方SDK官方文档先看（http://docs-im.easemob.com/im/android/sdk/import）
按照官方文档一步一步来，注册并创建应用,到环信官网下载环信 SDK。然后根据自己的需要导入自己想要的功能。我这里主要是单聊，以及圆形头像与昵称的保存。保存数据用的是ormlite。主要记录一下坑。这里就不具体讲登录注册了。
问题：public class MyChatFragment extends EaseChatFragment implements EaseChatFragment.EaseChatFragmentHelper 如果报错的话需要依赖
implementation 'android.arch.lifecycle:extensions:1.1.1'
问题：设置圆形头像找到EaseUserUtils
image.png
public static void setUserAvatar(Context context, String username, ImageView imageView){
EaseUser user = getUserInfo(username);
RequestOptions optionsCircle = new RequestOptions();
DrawableTransitionOptions transitionOptions = new DrawableTransitionOptions();
optionsCircle.placeholder(R.drawable.icon_head);
optionsCircle.transform(new GlideCircleTransform());
optionsCircle.diskCacheStrategy(DiskCacheStrategy.ALL);
if(user != null && user.getAvatar() != null){
try {
int avatarResId = Integer.parseInt(user.getAvatar());
Glide.with(context)
.load(avatarResId)
.apply(optionsCircle)
// .transition(transitionOptions.crossFade())
.into(imageView);
} catch (Exception e) {
Glide.with(context)
.load(user.getAvatar())
.apply(optionsCircle)
// .transition(transitionOptions.crossFade())
.into(imageView);
}
}else Glide.with(context)
.load(R.drawable.icon_head)
.apply(optionsCircle)
// .transition(transitionOptions.crossFade())
.into(imageView);
}
问题：发送的缩略图大小修改在EaseChatRowImage类里面 ，接收 登录环信后台修改大小
new AsyncTask<Object, Void, Bitmap>() {
@Override
protected Bitmap doInBackground(Object... args) {
File file = new File(thumbernailPath);
if (file.exists()) {
return EaseImageUtils.decodeScaleImage(thumbernailPath, 480, 480);
} else if (new File(imgBody.thumbnailLocalPath()).exists()) {
return EaseImageUtils.decodeScaleImage(imgBody.thumbnailLocalPath(), 480, 480);
} else {
if (message.direct() == EMMessage.Direct.SEND) {
if (localFullSizePath != null && new File(localFullSizePath).exists()) {
return EaseImageUtils.decodeScaleImage(localFullSizePath, 480, 480);
} else {
return null;
}
} else {
return null;
}
}
}
protected void onPostExecute(Bitmap image) {
if (image != null) {
imageView.setImageBitmap(image);
EaseImageCache.getInstance().put(thumbernailPath, image);
}
}
}.execute();
问题：UserCacheManager 获取用户个人信息默认通过本地数据库里面查询，有则使用本地的信息，没有则调取服务器信息
代码注释的地方则是从服务器上获取
/**
* 获取用户信息
* @param userId 用户环信ID
* @return
*/
public static UserCacheInfo get(final String userId){
UserCacheInfo info = null;
// 如果本地缓存不存在或者过期，则从存储服务器获取
if (notExistedOrExpired(userId)){
// HttpHelper.getInstance().getImInfo(context,userId, new NetWorkDataProcessingCallBack() {
// @Override
// public void onSuccess(Object response, String urlType, String msg) {
// if (response == null) return;
//
// UserBean userBean = (UserBean) response;
// save(userId,userBean.getName(),userBean.getImg());
// }
//
// @Override
// public void onError(String urlType, String msg) {}
// });
}
// 从本地缓存中获取用户数据
info = getFromCache(userId);
return info;
}
CjImHelper 这个类主要是环信的初始化之类的东西，以及消息的监听
public class CjImHelper {
private final String LOG_TAG = getClass().getSimpleName();
private Context mContext;
private EaseUI easeUI;
public boolean isVideoCalling;
public boolean isVoiceCalling;
// 记录是否已经初始化
private boolean isInit = false;
//监听
private EMConversationListener convListener;
public void setConvListener(EMConversationListener convListener) {
this.convListener = convListener;
}
private static CjImHelper mInstance;
private CjImHelper() {
}
public synchronized static CjImHelper getInstance() {
if (mInstance == null) {
mInstance = new CjImHelper();
}
return mInstance;
}
/**
* init helper
*
* @param context
* application context
*/
public void init(Context context) {
this.mContext =context;
initEasemob();
}
private void initEasemob(){
int pid = android.os.Process.myPid();
String processAppName = getAppName(pid);
// 如果APP启用了远程的service，此application:onCreate会被调用2次
// 为了防止环信SDK被初始化2次，加此判断会保证SDK被初始化1次
// 默认的APP会在以包名为默认的process name下运行，如果查到的process name不是APP的process name就立即返回
if (processAppName == null ||!processAppName.equalsIgnoreCase(mContext.getPackageName())) {
Log.e(LOG_TAG, "enter the service process!");
// 则此application::onCreate 是被service 调用的，直接返回
return;
}
if(isInit){
return ;
}
/**
* SDK初始化的一些配置

问题：混淆崩溃问题附上自己的百度地图，环信，Ormlite的混淆代码。。。最开始用demo里面的easeui混淆之后百度地图老是崩溃，最后发现替换里面的百度地图架包和so文件用最新的就好了，这是个大坑。。。。附上demo地址：https://github.com/lcjiang1993/CjEaseUiDemo 。 希望对出现问题的朋友有所帮助吧。
