引入SDK，jar包
修改AndroidManiFest 加入权限，activity
添加友盟appkey
配置各个平台的appkey
然后就可以分享：

new ShareAction(MainActivity.this).setPlatform(SHARE_MEDIA.QQ)
.withText("hello")
.setCallback(umShareListener)
.share();

监听：

private UMShareListener umShareListener = new UMShareListener() {
@Override
public void onStart(SHARE_MEDIA platform) {
//分享开始的回调
}
@Override
public void onResult(SHARE_MEDIA platform) {
Log.d("plat","platform"+platform);

            Toast.makeText(MainActivity.this, platform + " 分享成功啦", Toast.LENGTH_SHORT).show();

    }

    @Override
    public void onError(SHARE_MEDIA platform, Throwable t) {
        Toast.makeText(MainActivity.this,platform + " 分享失败啦", Toast.LENGTH_SHORT).show();
        if(t!=null){
            Log.d("throw","throw:"+t.getMessage());
        }
    }

    @Override
    public void onCancel(SHARE_MEDIA platform) {
        Toast.makeText(MainActivity.this,platform + " 分享取消了", Toast.LENGTH_SHORT).show();
    }
};

mShareAPI.getPlatformInfo(UserinfoActivity.this, SHARE_MEDIA.SINA, umAuthListener);

其中umAuthListener为授权回调，构建如下，其中授权成功会回调onComplete，取消授权回调onCancel，授权错误回调onError，对应的错误信息可以用过onError的Throwable参数来打印

private UMAuthListener umAuthListener = new UMAuthListener() {
@Override
public void onStart(SHARE_MEDIA platform) {
//授权开始的回调
}
@Override
public void onComplete(SHARE_MEDIA platform, int action, Map<String, String> data) {
Toast.makeText(getApplicationContext(), "Authorize succeed", Toast.LENGTH_SHORT).show();

}

@Override
public void onError(SHARE_MEDIA platform, int action, Throwable t) {
    Toast.makeText( getApplicationContext(), "Authorize fail", Toast.LENGTH_SHORT).show();
}

@Override
public void onCancel(SHARE_MEDIA platform, int action) {
    Toast.makeText( getApplicationContext(), "Authorize cancel", Toast.LENGTH_SHORT).show();
}};
