本人开发的开发者技术变现资源聚集地,大家支持下，下面是网址

一.生成key

二.mac os项目变大

删除 项目中app->build文件夹的intermediates文件夹

三.项目生成jar 和aar

四.android 友盟推送与阿里电商sdk同时继承冲突

（ERROR: Dex writing phase: classes.dex has too many IDs. Try using multi-dex)

这个原因是同时集成的友盟消息推送与阿里电商联盟的sdk jar中有相同的类，解决方法。

将PushSDK生成.arr文件后倒入项目，分别继承问题解决.  

路径：

cd /Users/hangliao/Desktop/umeng_message201710181609_3.1.3a.upush/PushExample/Pushlib/build/outputs/aar/Pushlib-release.aar

五.xls在线转换csv

https://cloudconvert.com/xls-to-csv

       contentLayout=(LinearLayout)convertView.findViewById(R.id.paomadeng_linelayout);

lunbo_textview = new TextView(getActivity());
lunbo_textview.setText("12121212");
lunbo_textview.setTextSize(13);
lunbo_textview.setSingleLine(true);
//设置字体颜色

Resources resource =   getActivity().getBaseContext().getResources();
ColorStateList csl = resource.getColorStateList(R.color.white_color);

lunbo_textview.setTextColor(csl);
LinearLayout.LayoutParams lunbo_textviewLayoutParameter = new LinearLayout.LayoutParams(LinearLayout.LayoutParams    .MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    lunbo_textviewLayoutParameter.topMargin=45;
lunbo_textviewLayoutParameter.leftMargin=13;
lunbo_textviewLayoutParameter.rightMargin=1;
lunbo_textview.setLayoutParams(lunbo_textviewLayoutParameter);

contentLayout.addView(lunbo_textview);



1.app真机调试报错

adb install -r 中出现INSTALL_FAILED_UNKNOWN_SOURCES，怎样解决？

D:android_code708 ools>adb install -r D:work_feixunGallery2.apk
3030 KB/s (7663016 bytes in 2.469s)
pkg: /data/local/tmp/Gallery2.apk
Failure [INSTALL_FAILED_UNKNOWN_SOURCES] 

解决：设置->安全->未知来源（允许安装来自未知来源的应用）。
